In jQuery: contains selector usage example_jquery

The example in this article describes the usage of the contains selector in jQuery. Share it with everyone for your reference. The specific analysis is as follows:

This selector matches elements containing the given text.
Syntax:

Copy code The code is as follows:

$(":contains(text)")

This selector is generally used in conjunction with other selectors, such as class selectors, element selectors, etc. For example:

Copy code The code is as follows:

$("li:contains('html')").css("color ","blue")

The above code sets the font color in the li element containing "html" in the text to blue.
If not used with other selectors, the default state is to be used with the * selector, for example, $(":contains") is equivalent to $("*:contains").
Parameter list:
