.size() returns 1 on multiple objects

[dominik.kukacka@…]

Hey,

I don't know if this is a bug but I think so.

I tried to select <input name="names[]"/> with $('input[name=names
[
]').size() and it returns zero!

The same with an ID But then it returns 1. <input id="names"/> with $('#names').size()

It works if I do it with a class (.names)

Here is a demo: ​http://lab.codecookie.net/jquery_array_selector/

This is not a bug, just an improperly escaped selector.

If you have a look at ​http://api.jquery.com/category/selectors/, you can see your exact example is covered:

"If you wish to use any of the meta-characters (#;&,.+*~':"^$[]()=>|/@ ) as a literal part of a name, you must escape the character with two backslashes. For example, if you have an an input with name="names[]"...", etc.

The #jquery IRC channel on Freenode or the support forums are also a great way to ask these types of questions.

Cheers.

yeah but if you had looked at my example you would have seen that I escaped it! $("input[name=names
[
]]").size()

ok here it looks not the right way.

I put two backslashes before each [ and ]

Hey,

here is the test case on jsFiddle.net: ​http://jsfiddle.net/FqXPb/

Thanks providing the test case! jQuery requires the uses of quotes when using attribute selectors not matter if you escape or not the meta characters.
