jquery selecter not compatible with

[[email protected]…]

old jquery 1.4.2 $("#foo").find('input[name=test[]]'); is right; new jquery 1.5.0 is error must $("#foo").find("input[name='test[]']"); More rigorous, but cannot and front version compatible

Thanks for taking the time to contribute to the jQuery project by writing a bug report.

As you didn't provide the test case required by the ​bug reporting guidelines I went ahead and made this one myself ​http://jsfiddle.net/jitter/njF8R/ . As you can see input[name=test[]] isn't a valid CSS selector and neither is it a valid selector in jQuery (if this worked in an earlier version then it was actually a bug that got fixed). So you should fix your code to use a valid selector.

The documentation is also pretty clear about these kind of selectors:

​http://api.jquery.com/category/selectors/

If you wish to use any of the meta-characters ( such as !"#$%&'()*+,./:;[email protected][\]^{`{|}~ ) as a literal part of a name, you must escape the character with two backslashes}

​http://api.jquery.com/category/selectors/attribute-selectors/

Attribute values in selector expressions must be surrounded by quotation marks.

​http://api.jquery.com/attribute-equals-selector/

Quotes are mandatory.

Basically a dupe of #8120
