jquery select element by name attribute

Question

I have an input with the name attribute:

<input type="text" name="data[foo][bar]" />

how can I select this element?

I tried $("input[name=data[foo][bar]]") but in vein.

Answer 1

Use

$("input[name=data\\[foo\\]\\[bar\\]]")

The documentation says:

If you wish to use any of the meta-characters ( such as !"#$%&'()*+,./:;<=>?@[]^`{|}~ ) as a literal part of a name, you must escape the character with two backslashes: \. For example, if you have an element with id="foo.bar", you can use the selector $("#foo\.bar").

Answer 2

$("input[name='data[foo][bar]']") 

Answer 3

Add quotes to the attribute value, otherwise you get conflicting square brackets and a parse error:

$("input[name='data[foo][bar]']")

Answer 4

$('input[name="data[foo][bar]"]')
