Example of usage of [attribute!=value] selector in jQuery_jquery

The example in this article describes the usage of the [attribute!=value] selector in jQuery. Share it with everyone for your reference. The specific analysis is as follows:

This selector matches all elements that do not contain the specified attribute, or that have an attribute that is not equal to a specific value.
This selector is equivalent to: not[([attr=value]).
To match elements that have a specific attribute but are not equal to a specific value, use [attr]:not([attr=value])
