Very Slow IE Multiple Selector performance on big html page

[anonymous]

This occurs on a rather big html page: 150kBytes and more than 700 "input, select, td and textarea" objects. Using IE6 or IE8, the unresponsive-script popup appears. The bug existed in jQuery 1.4.4 too.

Example code slow statement:

anchor.find("input,select,td,textarea");

Same effect but now fast:

anchor.find("input"); anchor.find("select"); anchor.find("td"); anchor.find("textarea");

"Workaround", actual code:

if ($.browser.msie) {

form.find("input").tooltip(); form.find("select").tooltip(); form.find("td").tooltip(); form.find("textarea").tooltip();

} else {

form.find("input,select,td,textarea").tooltip();

}

This was introduced in 1.4.3 when use of sourceIndex was dropped.

Duplicate of #7341.

For this case your "IE-only" solution works for all browsers, so just use that. Also, consider using event delegation via .delegate() rather than using .tooltip() for all 700 elements.

Thanks! I copied the 1.4.2 sourceIndex sorting code to our local jquery 1.5.2 version.

Version 1.6.1 fixes this. Thanks!
