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.
