if id includes char DOT the size() will be wrong in IE7

[zhengxianquan@…]

Example html:

span id="hotel.query.keyword"
span id="hotel_query_keyword"

Example Code:

var id = "span#hotel\\\.query\\\.keyword";
alert($(id).size()); //'''is 1 in FF but 0 in my IE7'''
id = "span#hotel_query_keyword";
alert($(id).size()); //is 1 both in FF and IE

In firefox 3.6.13, every thing is OK.
In IE7, the first result will be different to FF.

Whatever happened to people actually searching to see if an issue exists ...?

Duplicate of #7533.

It's not the same.

Please take a look to: ​http://jsfiddle.net/QYUPQ/1/

That link provides absolutely no evidence to suggest that this bug is not exactly the same as #7533. Furthermore, it’s invalid—you can’t have two elements with the same ID.

Your test case is invalid. There are two elements with the same id. That is not allowed.

This attribute assigns a name to an element. This name must be unique in a document. ​http://www.w3.org/TR/html4/struct/global.html#h-7.5.2
