Disable console.log statements (shows up with Ajax hyperlinks on 0.40-alpha1 and 0.40-dev3) #308

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?

Ajax Hyperlinks don't seem to be working anymore on 0.40-dev3. The following 
works fine on 0.40-dev2, but links don't work on 0.40-dev3.

main.html:

<!DOCTYPE html>
<html>
<head>
   <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
   <meta name="viewport" content="width=device-width; initial-scale=1.0; maximum-scale=1.0; user-scalable=0;"/>
   <link rel="stylesheet" href="iui/iui.css" type="text/css" />
   <link rel="stylesheet" href="iui/t/default/default-theme.css" type="text/css"/>
   <script type="application/x-javascript" src="iui/iui.js"></script>
</head>
<body>
   <div class="toolbar">
      <h1 id="pageTitle"></h1>
      <a id="backButton" class="button" href="#"></a>
   </div>
   <ul id="main" title="Main" selected="true">
      <li><a href="screen1.html">Go to Screen #1</a></li>
   </ul>
</body>
</html>

screen1.html:

<div id="screen1" class="panel" title="Screen 1">
<ul><li>Hello 1</li></ul>
</div>

What is the expected output? What do you see instead?

I expect the link to work (it does on 0.40-dev2).

What version of the product are you using? On what operating system?

0.40-dev3, Firefox 3.6.23 on Windows XP.

Please provide any additional information below.

Yikes!  Do you have a live URL I can test this on?  When you say the links 
"don't work" what do you mean?  What happens?  Nothing?  Have you looked in a 
browser debugger for error messages, etc?

Ajax links work fine in 0.40-alpha1 in the music sample, here:

(Although I haven't tested with Firefox 3.6 on Windows XP)

Hello. With "don't work" I mean that the new page does not load. The "spinning" 
image is shown but it keeps spinning forever.

I tried the two URLs you posted. Regular links work fine, Ajax links (e.g. the 
"Stats" link in the music demo or the "Ajax links" in the Link types demo) do 
not.

Looking at the Firefox javascript console, each time I click on one of those 
the following is logged three times:

Error: console is not defined
Archivo de origen: 
http://iui.googlecode.com/hg-history/REL-0.40-alpha1/web-app/iui/iui.js
Línea: 258

This is the following line in showPageByHref:

console.log("xhr.readyState = " + xhr.readyState);

Perhaps this is the cause of the problem.

As a side note: Once I click on one of these Ajax links the spinner keeps 
spinning forever and the page does not load, but more importantly -- once I get 
into this state none of the other links work either. The only option seems to 
be to reload the whole page.

Thanks.  In your app or local copy, try either deleting line 258 or commenting 
it out with //

We need to turn off all console.log statements in the next release.  Sorry 
about that.

Yes, commenting out the console.log line makes the link work.

I would like to suggest to use try..catch blocks so that in case of something 
going wrong, the iui.busy flag is not kept set forever.

In my case, the call to console.log caused an exception and from then on, no 
links on the page would work anymore (because iui.busy flag was set). This can 
be easily avoided:

    showPageByHref: function(href, args, method, replace, cb)
    {
            try
            {
                [...rest of the code...]
            }
            catch (err)
            {
                iui.busy = false;
            }
    },

Thanks for following up.   Thanks also for suggesting the try..catch block -- 
the busy flag makes that a really good idea.

We'll use Issue #25 for tracking the try/catch work.  (And I'm changing the 
summary of this one to indicate that the console.log is, in fact, the problem)

Short-term fix (commenting out 2 console.log statements) is checked into source 
control:
http://code.google.com/p/iui/source/detail?r=da4b81fa4b508a8bad8cb2b40c0784475a0

(first iUI change checked in to source control since we switched to Git)
