Attribute Not Equal Selector [name!=”value”]

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

jQuery(“[attribute!=’value’]:)

attribute: An attribute name.

value: An attribute value Can be either a valid identifier or a quoted string. 

The selector is equivalent to : not ([attr=’value’])

Additional Notes:

  • 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 providing by the native DOM query Selectpr All () method. For better performance in modern browsers, use $(“your-pure-CSS-Selector”).not(“[name=’value’]”) instead.

Example:

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