"unexpected call to method or property access" in IE8

in Using jQuery • 2 years ago

I've built a menu based off the tutorial by Soh Tanaka at http://www.sohtanaka.com/web-design/mega-drop-downs-w-css-jquery/.

The menu works in Firefox, Chrome, Safari and even in IE. However IE8 gives the error:
"unexpected call to method or property access". I'm pulling the jQuery library from http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.js so I can narrow down the error. IE says the problem is at line 4075 character 5. That line is:

this.appendChild( elem );

I've got Firebug installed in Firefox and I'm not getting any error at all. This only happens in IE8 (that I've tested) but the menu works fine. In fact all my jQuery elements are working.

In the page I'm using these plug-ins (listed in the order they are set in the page):

jQuery 1.4.2
jQuery UI 1.8
CKEditor
CKEditor Adapters
BlockUI
jQuery Form (for serializing forms)
ColorBox
HoverIntent

Any clues as to why IE8 is griping? Oh and if I have my document.ready() at the top of the page then the UI breaks. However putting the document.ready() at the end of the page works.

IE8 has a *great* debugger. Load the page and press F12, then debug the script. Take a look at the call stack at the point of the error and see who's causing it.

Actually the debugger seems to be no help at all. The call stack simply points me to exactly what I already knew (screenshot attached). However it doesn't seem to point to what is triggering the call?

The screenshot of the debugger is the results of simply loading the page. The page only has the menu on it and nothing else. The error occurs when the page is first rendered and only occurs in IE.

This is really odd. Today the error is disappearing and reappearing today. Back-and-forth, on-and-off. I literally didn't change a bit of code. Just fired up the browser to look at the problem again and it's wasn't happening. Then it came back. Refresh again and it's gone. It's been intermittent like this all morning.

Co-worker is working on another page and the error showed up for him but not for me when I hit the page. Seems that there's some gremlins in IE8 (big surprise eh?)

I have thesame problem - the error only shows when I try to use jquery.tooltip on mouseover (the tooltip isn't working because of this)

still looking for a solution

I've just been working through a similar problem with my site. An initial fix was to remove any 'button' elements from my document.ready function ( written: '$(function()' ) - as it seems IE 8 (and using I.E Tester 5.5, 6 & 7) does not support this JQueryUI feature:

JS Before Code:
$(function() {
$("yourBtn").button().click(function() { yourFunction() });
});

HTML Before Code:
<yourBtn>Submit</yourBtn>

JS After Code:
$(function() {

});

HTML After Code:
<a href="#" onclick="yourFunction(); return false;">Submit</a>

No single fix is going to solve all problems, but hopefully this helps some of you.

Kind Regards

Jim

I had this problem. It turned out to be an extra closing tag in the value I was trying to append, which IE apparently doesn't like. Check the value of "elem" right before you append it.

I had the same message, again IE8 specific, with jQuery 1.3.2 or 1.4.2. After a bit of testing, it turns out that IE8 can't insert into elements it doesn't recognise, like the HTML5 <section> and <header> elements. The debugger shows that these elements have the 'canHaveHtml' property set to false, which could be useful if you need to code around this. The simple workaround is to use good old-fashioned <div> elements instead.

Searching around, I found that others have had this problem trying to insert into <ul> or <tbody> elements. Since these only accept a specific child element (<li> or <tr>), IE doesn't trust you to insert arbitrary text into them.

I recommend you try the HTML Shiv (http://code.google.com/p/html5shiv/) or Modernizr Library (http://www.modernizr.com/). That will take the troublesome unrecognizable elements and make them understandable to IE 6, 7 and 8.

So I ran into this same error trying to do this:

var theFields = $( "fieldset", theForm );
$( "#child-within-theForm", theForm ).append( theFields );

adding .innerHTML to my theFields object makes it work fine.

var theFields = $( "fieldset", theForm );
$( "#child-within-theForm", theForm ).append( theFields.innerHTML );

Hope this helps!

I was calling $("#my_element_id").button() on img (image) elements which seemed to drive IE bonkers. I'm still working on a fix.

Hello,

I had the same problem. The reason in my case was invalid markup. I.e. try to validate your html code and probably the bug will disappear.

I had same error while trying to use Craig Thompson's Simpletip on an img element which is in a table cell. I wrapped the img in a span and applied the Simpletip to that and it did the trick.

<td style="width: 10px">
<span id ="spancoldstartstatusled"><img alt="" id="coldstartstatusled" src="../images/icons/ledgray.png" /></span>
</td>
