Javascript Error when editor is not visible #4

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Hi,

I use the editor on a div with multiple tabs (also divs). When the tab with the 
editor is invisible then 
every few milliseconds you get an JS error ("null value").

Debugging a packed JS file is not very practical, so I cannot see where the 
error occurs.

BTW I could really use the un-packed JS files of WMD. When will you upload them?

Thanx, Bart

I should add: the visibility of the div is done with CSS.

I have same error, which occurs in wmd-base.js line 475

7.setTop=function(6f, 70, 71){
    var _72=_7.getPixelVal(_6f.style.top);
...

}

Uncaught TypeError: Cannot read property 'style' of null

Occurs while using jQuery Tabs, when WMD is on a hidden tab.

I'm experiencing the same error.  The following error messages are repeated in 
a seemingly infinite loop.

This is from firebug in Firefox 3.6.8

First:
uncaught exception: [Exception... "Component returned failure code: 0x80004005 
(NS_ERROR_FAILURE) [nsIDOMNSHTMLTextAreaElement.selectionStart]" nsresult: 
"0x80004005 (NS_ERROR_FAILURE)" location: "JS frame :: 
http://localhost:3000/javascripts/wmd/wmd-base.js :: anonymous :: line 565" 
data: no]

Second:
[Break on this error] (no source for )
_6f is null
[Break on this error] var _72=_7.getPixelVal(_6f.style.top); 

Background:
My WMD include tag is nestled right against the closing body tag.  
I'm on OS X 10.6.4
Firefox 3.6.8

Context:
I experience the error when I use unobtrusive javascript to update the form 
container that holds my  WMD text field.

I get this error when I do not use the wmd library correctly. If the wmd editor 
is hidden when you load the page, then you need to add the following line 
BEFORE you load the wmd script: 

wmd_options = { autostart: false };

I recall there is something in the docs about it.
