Description
I can't get element value by id if id value contains "[number]".
Lets say i have input field:
<input type="text" name="USERNAME[0]" id="USERNAME[0]" value="username" />
When I call alert($('#USERNAME[0]').val()); then it says undefined, but if I use this example:
<input type="text" name="USERNAME2" id="USERNAME2" value="username2" />
and call alert($('#USERNAME2').val()); then I get correct value.
Little example: http://office.5dvision.ee/~kullar/Testid/jQuery_Test/jquery.php
you are falling afoul of the escaping rules: jQuery interprets [] as indices, so you'll need to specify your hardcoded square brackets as \\[\\] to jQuery (which means you'll need to write \\\\[\\\\] into the string).
Try alert($('#USERNAME\\\\[0\\\\]').val()); .
