Attribute does not equal ([foo!=bar])

Syntax

$('[attr != theValue]')

Description

Select all elements that do not have the attr attribute, or have an attr attribute but with a value other than theValue.

Selectors see attribute values as a single string, $('a[rel!=nofollow]') will select <a rel="nofollow self" href="example.htm">Some text</a>.

Examples

Selector	Selects
$('a[rel!=nofollow]')	all <a> elements that either have no rel attribute, or have one with a value other than nofollow
$('input[name!=myname]')	all <input> elements that either have no name attribute, or have one with a value other than myname
