Blank page when calling changePage on dynamically generated page #23

Open sergehuber opened 12 years ago

sergehuber commented 12 years ago

Hello,

First of all thanks for the work on multiview, it looks really powerful and actively maintained, which is great. I really believe this functionality should go into the core of JQuery Mobile because it is so essential !

I'm having a real issue. I've started my code using the examples from : http://jquerymobile.com/test/docs/pages/page-dynamic.html before actually integrating with multiview, and all seemed to work fine.

Now I'm trying to get it to work with multiview but whenever I click a link I get a blank page. I've seen that maybe I should specify the pageContainer myself, so I've tried adding that. Right now here is the code I'm using : 

    var pageSelector = urlObj.hash.replace(/\?.*$/, "");
    console.log('pageSelector=' + pageSelector + ' node=' + node);
    if (node) {

        if ($(pageSelector).length == 0) {
            console.log("showNodeDetails: unable to find page with selector " + pageSelector + ", aborting rendering !");
            return;
        }
        var $page = renderNode(pageSelector, node);

        // We don't want the data-url of the page we just modified
        // to be the url that shows up in the browser's location field,
        // so set the dataUrl option to the URL for the category
        // we just loaded.
        options.dataUrl = urlObj.href;
        options.pageContainer = $('div:jqmData(id="main")');

        // Now call changePage() and tell it to switch to
        // the page we just modified.
        if (!refresh) {
            console.log("showNodeDetails: Now changing page dynamically...options.pageContainer=" + options.pageContainer);
            $.mobile.changePage($page, options);
        }
    } else {
        console.log("No valid node for " + nodePath + " was found !");
    }

Despite specifying the pageContainer (and I checked by debugging that I to get a valid object), whenever I change the page it becomes completely blank, as if the pageContainer was being ignored or something.

I'd appreciate any help, especially since I have to demo this in two days and would love to give multiview a nice plug :)

hm. If you can post your basic html, I could have a quick look (also deadline on Monday....)

For now I can only guess:

Multiview navigation works similar to the dynamic page example, BUT I'm not preventdefaulting the original changePage. The dynamic page example (a) catches the changePage on pagebeforechange,(b) modifies parameters, (c) STOPS IT and (d) fires a NEW changePage, while I'm only re-directing the incoming changePage.

If you are tampering with the original event, this may be a reason it's not working (latest version here).

If you want to track your changePage call through the multiview plugin, set consoles at the following points:

Incoming: 1) mainEventBindings, on pagebeforechange = here I capture all incoming changePage calls before modifying. console.log(data) to see what is coming in.

2) mainEventBindings, inside "backFix-handler" (you should not end up INSIDE on forward transitions), here I check for the last backwards transition on a panel

3) mainEventBindings, inside all IFs, that end the function with return. Multiview only allow data.toPage to be a string, but since you get a white page, you should not end here.

Forward transitions: 4) panelTrans function = There is an if-else statement. If = panel transition, else = JQM transition. Console both and see which one fires. Also inside the if = panel transition, console.log( data ) after it's modified to see what comes out.

Cleanup 5) PaneltransitionCleaner = this will fire on all transitions (back/fwd JQM/multiview), but the problem must be prior to it.

Let me know, what you get from the consoles. Then we see, where we go from there

Hello,

Thank you so much for your (very) quick reply !

I'm not sure if the HTML would help in it's current state since it has a lot of non-multiview code and I would probably need to simplify it greatly to send it here. I'll see if I can get that done.

Also I had a quick question, I'm no big javascript expert: do you have a recommendation to dump object to the console log ? Because I tried adding a console.log to the pagebeforechange but I get something like : 

            console.log("multiview.pagebeforechange data=" + data);

produces:

2012-06-22 20:53:37.635 Wise[3770:13403] [INFO] multiview.pagebeforechange data=[object Object]

I'm still working on integrating all the suggestions you made, as soon as I have done that I'll send some logs.

Btw the deadline I have is actually a webinar, if you're interested here is the invitation info: http://www.jahia.com/cms/home/about-us/events/content-main/events-list/jahia-webinar---native-multi-pla.html

Best regards, Serge Huber.

Ok I've added a few logs, hopefully in the right locations, here is the log extract I get from clicking on a link with a data-panel='main' from a panel menu.

Please note that I am indeed implementing the changePage with the preventDefault mechanism as in the JQM example, and also that I am changing to a DOM page (not of type string) in the second call. I think this is possibly the problem, see my (beginner's) analysis below.

Here is the log :

I think the problem occurs in the following code:

            // block trailing hashchange (objects) - including dialogs/custom selects               
            if (typeof data.toPage !== 'string' ) {                 

                if ( data.options.role != "custom-select" ) {
                    o._backFix = false;
                    console.log('multiview.pagebeforechange return because of non-string toPage and non-custom select');
                    return;
                    } 
                }

As my toPage is not of type string, and I don't set any role (not sure what this is btw), the method stop executing here and returns.

I hope this is enough to help diagnose the problem, please let me know how I can assist you in getting to the bottom of this, your helps is GREATLY appreciated.

Best regards, Serge Huber.

Don't put any text in the console.log, when you want to see the object.

console.log("this is ="+ data )

will give you object object

console.log("this is=")
console.log( data )

will give you the full object with all parameters

frequent commented 12 years ago

Then if you get the data object, check what:

 data.toPage
 data.options.fromPage
 data.options.pageContainer

are. If any of these are empty or wrong or toPage is an object, you have your false transition.

Not sure how to handle prevDefault, but if you have to use it, you have to make sure, that what initially gets "passed into" the multiview pageBeforeChange handler also gets "passed out" (including your changes I assume).

If you have an object as data.toPage... which I'm just rechecking is probably the case depending on what this is:

   var $page = renderNode(pageSelector, node);

then you have to create the data-url or path you want to go to by hand and pass it in as a string:

If you can use data-url, try either one of those:

  $page.jqmData('url')  or  $page.attr('data-url')

To see how to make an object into a string check my BACKFIX option in MAINEVENTBINDINGS. I'm doing the same there, because the last backwards transition before reaching the first page only passes on object as far as I noticed. So I need to convert the object to string to trigger the transition.

Try the same.

Hi,

Thanks again for your help, the week-end was a frustrating one. I tried adding console logs for the data, for example in the following form : 

                console.log("multiview.pagebeforechange");
                console.log(data.toPage);
                console.log(data.options.fromPage);
                console.log(data.options.pageContainer);

But then in the output I would always get :

2012-06-25 08:50:38.478 Wise[1341:13403] [INFO] multiview.pagebeforechange

2012-06-25 08:50:38.480 Wise[1341:13403] [INFO] error JSON.stringify()ing argument: TypeError: JSON.stringify cannot serialize cyclic structures.

I then tried to use the decycle Javascript code from https://github.com/douglascrockford/JSON-js and tried to modify this to look like console.log(JSON.stringify(JSON.decycle(data)) but this was even worse, I was getting infinite loops (so much for decycling :().

I then started writing my own object dumping code, but this was not trivial for someone still a bit young in Javascript code but at least I got some results. I used the following code : 

var alreadyVisited = [];
var currentPath = [];

function dumpObjectProperties(curObject) {

    recurseDumpObjectProperties(curObject, 0);

    alreadyVisited = [];
    currentPath = [];
}

function getNodePath(htmlNode) {

    var path = [];

    do {
        path.unshift(htmlNode.nodeName + (htmlNode.id ? ' id="' + htmlNode.id + '"' : '') + (htmlNode.className ? ' class="' + htmlNode.className + '"' : ''));
    } while ((htmlNode.nodeName.toLowerCase() != 'html') && (htmlNode = htmlNode.parentNode));

    return path.join(" > ");

}

function recurseDumpObjectProperties(curObject, depthPadding) {
    var depthPaddingString = "";
    for (i =0; i < depthPadding; i++) {
        depthPaddingString += " ";
    }
    if ($.inArray(curObject, alreadyVisited) !== -1) {
        console.log(depthPaddingString + 'already visited object at ' + currentPath);
        return;
    }
    if (depthPadding > 4) {
        console.log(depthPaddingString + 'aborting output because of depth');
        return;
    }
    alreadyVisited.push(curObject);
    currentPath.push(curObject);
    console.log(depthPaddingString + '{');
    for (var objectPropertyKey in curObject) {
        var objectPropertyValue = curObject[objectPropertyKey];
        if (objectPropertyKey == 'outerHTML' || objectPropertyKey == 'innerHTML') {
            console.log(depthPaddingString + '   ' + objectPropertyKey + ' : \'HTML stripped\'');
        } else if (objectPropertyKey == 'outerText' || objectPropertyKey == 'innerText') {
                console.log(depthPaddingString + '   ' + objectPropertyKey + ' : \'Text stripped\'');
        } else if (typeof objectPropertyValue == 'object') {
            if (objectPropertyValue instanceof Node) {
                console.log(depthPaddingString + '   ' + objectPropertyKey + ' : ' + getNodePath(objectPropertyValue));
            } else {
                console.log(depthPaddingString + '   ' + objectPropertyKey + ' : ');
                recurseDumpObjectProperties(objectPropertyValue, depthPadding + 2);
            }
        } else if (typeof objectPropertyValue == 'function') {
            // don't dump functions, they are not needed most of the time.
        } else {
            console.log(depthPaddingString + '   ' + objectPropertyKey + ' : ' + curObject[objectPropertyKey]);
        }
    }
    console.log(depthPaddingString + '}');
    currentPath.pop();
}

I got the following result for a single page click:

As you can see it seems that the multiview event handler is always called before my own pagebeforechange code, which is the one that actually builds the page. As you have correctly analyzed I do pass an object to the changePage method (the second time), but I haven't had the time to try your suggestions yet, as I am not sure how to integrate them yet.

I should mention that I am also using the page parameters the same way they are provided in the example provided by the JQuery Mobile documentation here: http://jquerymobile.com/test/docs/pages/page-dynamic.html

Hi Serge,

I have my deadline in 2hrs. I will check once I'm back home and cought some sleep... I also did a lot of improv over the weekend. I will commit this afternoon. Then you can try again with the latest version, which is running ok on my project site (regular JQM pages with popovers and main/menu with popovers)

Regards,

Sven

Hi,

Thanks again for your help, the week-end was a frustrating one. I tried adding console logs for the data, for example in the following form : 

                console.log("multiview.pagebeforechange");
                console.log(data.toPage);
                console.log(data.options.fromPage);
                console.log(data.options.pageContainer);

But then in the output I would always get :

2012-06-25 08:50:38.478 Wise[1341:13403] [INFO] multiview.pagebeforechange

2012-06-25 08:50:38.480 Wise[1341:13403] [INFO] error JSON.stringify()ing argument: TypeError: JSON.stringify cannot serialize cyclic structures.

I then tried to use the decycle Javascript code from https://github.com/douglascrockford/JSON-js and tried to modify this to look like console.log(JSON.stringify(JSON.decycle(data)) but this was even worse, I was getting infinite loops (so much for decycling :().

I then started writing my own object dumping code, but this was not trivial for someone still a bit young in Javascript code but at least I got some results. I used the following code : 

var alreadyVisited = [];
var currentPath = [];

function dumpObjectProperties(curObject) {

    recurseDumpObjectProperties(curObject, 0);

    alreadyVisited = [];
    currentPath = [];
}

function getNodePath(htmlNode) {

    var path = [];

    do {
        path.unshift(htmlNode.nodeName + (htmlNode.id ? ' id="' + htmlNode.id + '"' : '') + (htmlNode.className ? ' class="' + htmlNode.className + '"' : ''));
    } while ((htmlNode.nodeName.toLowerCase() != 'html') && (htmlNode = htmlNode.parentNode));

    return path.join(" > ");

}

function recurseDumpObjectProperties(curObject, depthPadding) {
    var depthPaddingString = "";
    for (i =0; i < depthPadding; i++) {
        depthPaddingString += " ";
    }
    if ($.inArray(curObject, alreadyVisited) !== -1) {
        console.log(depthPaddingString + 'already visited object at ' + currentPath);
        return;
    }
    if (depthPadding > 4) {
        console.log(depthPaddingString + 'aborting output because of depth');
        return;
    }
    alreadyVisited.push(curObject);
    currentPath.push(curObject);
    console.log(depthPaddingString + '{');
    for (var objectPropertyKey in curObject) {
        var objectPropertyValue = curObject[objectPropertyKey];
        if (objectPropertyKey == 'outerHTML' || objectPropertyKey == 'innerHTML') {
            console.log(depthPaddingString + '   ' + objectPropertyKey + ' : \'HTML stripped\'');
        } else if (objectPropertyKey == 'outerText' || objectPropertyKey == 'innerText') {
                console.log(depthPaddingString + '   ' + objectPropertyKey + ' : \'Text stripped\'');
        } else if (typeof objectPropertyValue == 'object') {
            if (objectPropertyValue instanceof Node) {
                console.log(depthPaddingString + '   ' + objectPropertyKey + ' : ' + getNodePath(objectPropertyValue));
            } else {
                console.log(depthPaddingString + '   ' + objectPropertyKey + ' : ');
                recurseDumpObjectProperties(objectPropertyValue, depthPadding + 2);
            }
        } else if (typeof objectPropertyValue == 'function') {
            // don't dump functions, they are not needed most of the time.
        } else {
            console.log(depthPaddingString + '   ' + objectPropertyKey + ' : ' + curObject[objectPropertyKey]);
        }
    }
    console.log(depthPaddingString + '}');
    currentPath.pop();
}

I got the following result for a single page click:

As you can see it seems that the multiview event handler is always called before my own pagebeforechange code, which is the one that actually builds the page. As you have correctly analyzed I do pass an object to the changePage method (the second time), but I haven't had the time to try your suggestions yet, as I am not sure how to integrate them yet.

I should mention that I am also using the page parameters the same way they are provided in the example provided by the JQuery Mobile documentation here: http://jquerymobile.com/test/docs/pages/page-dynamic.html

Thanks a lot Sven for all your help, and good luck with your deadline !

On my side I will try to see if I can do anything about the ordering of events, since I think this might be a part of the problem.

Best regards, Serge Huber.

Hi Serge,

I have my deadline in 2hrs. I will check once I'm back home and cought some sleep... I also did a lot of improv over the weekend. I will commit this afternoon. Then you can try again with the latest version, which is running ok on my project site (regular JQM pages with popovers and main/menu with popovers)

Regards,

Sven

Hi,

Thanks again for your help, the week-end was a frustrating one. I tried adding console logs for the data, for example in the following form :

               console.log("multiview.pagebeforechange");
               console.log(data.toPage);
               console.log(data.options.fromPage);
               console.log(data.options.pageContainer);

But then in the output I would always get :

2012-06-25 08:50:38.478 Wise[1341:13403] [INFO] multiview.pagebeforechange

I then tried to use the decycle Javascript code from https://github.com/douglascrockford/JSON-js and tried to modify this to look like console.log(JSON.stringify(JSON.decycle(data)) but this was even worse, I was getting infinite loops (so much for decycling :().

I then started writing my own object dumping code, but this was not trivial for someone still a bit young in Javascript code but at least I got some results. I used the following code :

var alreadyVisited = [];
var currentPath = [];

function dumpObjectProperties(curObject) {

   recurseDumpObjectProperties(curObject, 0);

   alreadyVisited = [];

As you can see it seems that the multiview event handler is always called before my own pagebeforechange code, which is the one that actually builds the page. As you have correctly analyzed I do pass an object to the changePage method (the second time), but I haven't had the time to try your suggestions yet, as I am not sure how to integrate them yet.

I should mention that I am also using the page parameters the same way they are provided in the example provided by the JQuery Mobile documentation here: http://jquerymobile.com/test/docs/pages/page-dynamic.html

sergehuber commented 12 years ago

Ok here is the latest from my analysis. Basically I am building URLs for pages that look like this :

test

I was using the "pagebeforechange" event as it was provided in the JQuery example to remove the parameters, prevent the default event, and then perform a call to the "#viewNode_jnt_folder" page dynamically.

This seems to be completely incompatible with the current version of multiview, because I cannot seem to be able to put a hook in the proper location to perform this rewrite. I tried using the click, but it seems that a "hashchange" is also being triggered and basically it seems that for each page change both a click and a hashchange are being generated ? The hashchange is also listened to by multiview so I wasn't sure how to get around this.

Maybe multiview could add it's own events so that we could plugin such logic ?

I didn't try yet with the https://github.com/jblas/jquery-mobile-plugins/tree/master/page-params but I'm not sure how well that works with multiview ?

At this point with my dead line I think I will probably have to look for another way of doing layouts that using multiview, I just can't get it to work properly. I think that there definitely needs to be a best practice for building dynamically generated pages with this plugins, because I'm really struggling for the lack of this.

Regards, Serge Huber.

Agree on best practice. Currently they are not supported very well I think.

Regarding your links: Run these through JQMs $.mobile.path.parseURL( "your_link" ) and see what JQM makes of them.

This is what I get:

   authority       "github.com"
   directory     "/frequent/multiview/issues/"
   domain       "https://github.com"
   doubleSlash   "//"   
   filename     "23"
   hash     "#viewNode_jnt_folder?nodePath=/test"
   host     "github.com"
   hostname    "github.com"
   href      "https://github.com/freq...t_folder?nodePath=/test"
   hrefNoHash  "https://github.com/frequent/multiview/issues/23"
   hrefNoSearch   "https://github.com/frequent/multiview/issues/23"
   password    ""
   pathname   "/frequent/multiview/issues/23"
   port    ""       
   protocol   "https:"
   search  ""
   username  ""

I can only guess a file ending would be helpful as in 23.html

Anyways: JQM always fires two events ("on window.hashChange and on pushstate") on every transition (links and programmatic calls). This is really difficult to tailor to, because you never know:

a) which event comes first, 
b) sometimes there is only one event (last backwards transition/non-pushstate devices)
c) sometimes they are string & object (default), sometimes object only 
d) dialogs, popups also use hashChange but have no means of distinguishing them from pure navigation events

Most of the time working on Multiview goes into trying to identify the correct event and blocking everything else whithout creating infinite loops. I'd say this is about half the plugin code, which I hoped to shrink in size, but which just keeps getting larger... Also I'm having to rely a lot on JQMs data-url, because if you get string in a link like this:

   http://www.somepage.com/folder/with/whatever/foo.html#some

it's not possible to identify an existing page by id only. I can only take one (string preferred), because taking both string and object usually end in infinite loops.

Anyway, sorry I can't help right now with your dynamic links. I'm happy I can get basic deeplinks to work, which is hard enough.

Hello Sven,

Unfortunately I couldn't get it to work on time, but I found one of the problem I was having. I was assuming that links that didn't point to another panel did not need the data-panel attribute but it seems that after debugging it was required. I'm not sure if this was due to the dynamic pages, but this helped solve the pageContainer resolution which was causing some problems.

After that I had some navigation issues, mostly the back navigation that wasn't working and this is where I ran out of time. Also some of the dynamically inserted components were not being properly being created, despite the fact that I was sending "create" triggers.

It seems to me that this is more a global JQM problem than a multiview problem, and that these two libraries are not yet very focus on dynamic pages creationg and insertion, and rely more on server-side generated pages, even if they are loaded through AJAX. Does this assumption seem right ?

Anyway I really wanted to thank you for your help, you have been really great about answering my questions quickly despite being on your own dead line. I hope that I can come back to multiview in the near future.

In the end I chose to go with the basic JQM Docs layout for both smartphone and tablet layouts, despite being a lot less powerful it was simpler for me to get working.

I really think that multiview should become a central part of JQM because it makes no sense to make to have a mobile framework that doesn't handle multiple layouts natively.

Best regards, Serge Huber.

Hello Serge,

re dynamic pages. I'm currently also trying to stay from them. I load a shell page and then add/remove content via Ajax. Right now more of a time contraint, so I haven't been able to give this more thought in multiview. In general, multiview should be able to handle dynamic pages and even content sections, because I have added the pageContainer to JQM urlHistory.

The default JQM urlHistory stores pages without reference to where they are in the document (since default JQM is the body tag). By adding pageContainer to the history, I can tell JQM the page is going on the body (regular JQM page) or on a panel (multiview page). You could to the same with content sections I assume.

Regarding the back button. That is the trickiest part, especially since all browser handle it differently and you have little insight into what is stored. Regarding multiview, there were still some bugs which I'm about to fix up, so the next commit should be ok. Of course... there is also the forward button...

So your project went ahead well. Give multiview some time to sort things out and JQM some time to find a solution that works cross-browser/device for panel layouts.

Cheers,

Sven
