How can I remove a class from an element with a matching attribute/value?

Question

Using jQuery, how can I remove the class header from all <th> elements with the attribute nofilter="True"?

<th class="header" nofilter="True" scope="col" align="left">City</th>

The result should be:

<th nofilter="True" scope="col" align="left">City</th>

Answer 1

As the comments noted, I rushed my answer, the correct statement would be

$("th[nofilter='True']").removeClass("header");

Answer 2

Use the Attribute Equals Selector:

$("th[nofilter='True']").removeClass("header");

Answer 3

$("th[nofilter='True']").removeClass("header");

this should work for nofilter="True" only
