Compound selectors dont work well in IE7

[stuart.innes@…]

tried something like in IE7 $(".item1 a, .item2 a").live('click',function(){

do stuff

})

The script will timeout(prompt to force stop) with medium data-sets (about 150-200 matching items)or takes an inordinate length of time to complete.

Thanks for taking the time to contribute to the jQuery project! Please provide a reduced test case on  http://jsfiddle.net that reproduces the issue experienced to help us assess your ticket.

Additionally, test against the jQuery (edge) version to ensure the issue still exists.

It wouldn't surprise me that this peformed poorly in IE6/7, since the only way to satisfy that query is to make a pass through the entire document to find the correct classes and descendants. And it has to be done each time a click occurs. Other browsers support querySelectorAll so they can do this faster.

Try a better-qualified selector, using ids or just a single class selector qualified by a tag name, such as div.itemX.

Replying to stuart.innes@…:

the bug is that selecting $('#a #b #c'); is not working in ie7, to solve it I used $('#a #b').find('#c');

this bug should be reopened
