Answer 3

You need to escape with " \\\\ "

From Jquery docs:

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 4

Put the name value in quotes:

$('input[name="field_name[array_key]"]').removeClass('selected');

As stated by the jQuery docs :

Quotes are mandatory

Here's a live example of the above code.
