repeated toggle() goes out of sync (IE8)

[nbr]

I tried using $(...).toggle() for two elements of which one was hidden and one visible.

Expected results: the visible one goes hidden and vice versa. The next click returns the elements as they originally were.

Actual results on IE8: the first toggling was ok, but the second click hides both elements.

See attached test case, or here: ​http://www.iki.fi/naapuri/testit/toggle.html

Showing IE8's display none bug

[brianmoschel]

This issue is a bug in IE8 where display:none under certain circumstances will not allow the element's height and width to be 0px. Since ":hidden" checks 0 height and width, toggle() keeps trying to hide the element instead of show()-ing it.

The attached HTML file shows a simple test case with 3 span elements. The middle span element is set to display:none, but in IE8 the height is 19px and width is 4px. Earlier IE's and other browsers all show the height and width of this element at 0px.

Setting height and width to 0 manually doesn't help, and I haven't found any info on this bug on the web. So the possible solutions are a) find a method to force height/width of elements to 0 in IE8 (not sure how) or b) change ":hidden" to check display:none instead of 0'ed height and width.

This seems to happen with inline elements that have inline elements before and after them. The problem goes away when you remove the first span.

Actually, this is the same issue as experienced in #4512, which was solved using:

force = /^{tr$/i.test( elem.nodeName ); ticket #4512}

This ticket can be resolved by adding span to that regex:

force = /^{tr|span$/i.test( elem.nodeName ); ticket #4512}

However, someone has recently reopened #4512, saying they see the same issue with ul elements, and I've even seen it with divs that have display:inline, so I don't think this is a good solution. Might this be something that uses feature detection testing?

I just found this issue (the hard way) on jQuery 1.4.2 and IE8. Using the toggle.html attached file and changing to jQuery 1.4.2, same thing happens; this is a bummer for the latest version of jQuery and IE!

A simple workaround is to use a <div style='display: inline'> instead of a <span> tag.

This should be fixed now with the fix for #4512.
