Attribute not equal selector [name!=”value”]

Select elements that either don't have the specified attribute, or do have the specified attribute but not with a certain value.

This selector is equivalent to :not([attr='value']).

Because [name!="value"] is a jQuery extension and not part of the CSS specification, queries using [name!="value"] cannot take advantage of the performance boost provided by the native DOM querySelectorAll() method. For better performance in modern browsers, use $( "your-pure-css-selector" ).not( "[name='value']" ) instead.

jQuery( "[attribute!='value']" )

version added: 1.0

Examples:

Finds all inputs that don't have the name 'newsletter' and appends text to the span next to it.
