jQuery Incorrectly Parses Form Variable Names Containing # Character and [array]

[[email protected]…]

Given the following general structure, embedded inside a web page with a form, etc. Testing in FireFox 7.0.1 with jQuery v1.6.1

===================================================

<table class="form-table targetOne">

<tr> <th valign="top">Location</th> <td>

<label>

<input type="radio" value="page" name='foo#bar[baz]' checked='checked' />Page </label> &nbsp;

<label>

<input type="radio" value="profile" name='foo#bar[baz]' />Profile </label> &nbsp;

<label>

<input type="radio" value="tab" name='foo#bar[baz]' />Tab </label> &nbsp;

</td>

</tr>

</table>

======================================================================

jQuery("input[name=foo#bar[baz]]:checked").val();

...returns "undefined", when it should return the value of the currently selected radio button.

Changing the "name" in the form to match...

jQuery("input[name=foo#bar]:checked").val(); WORKS

jQuery("input[name=foo[baz]]:checked").val(); WORKS

jQuery("input[[email protected][baz]]:checked").val(); WORKS

But the # character combined with a sub-array causes jQuery to fail.

Have you tried escaping the special character and putting the mandatory quotes around the attribute value?

Have you tried escaping the special character and putting the mandatory quotes around the attribute value?

Please post an example of what you're referring to.

Escaping the '#' character solves this: ​http://jsfiddle.net/GQeGW/
