In jQuery: header selector usage example_jquery

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

This selector can match heading elements, that is (h1-h6).

Grammar structure:

Copy code The code is as follows:

$(":header")

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:

$(".qiantai:header").css("color","blue ")

The above code can set the font color in the title element with the class name qiantai to blue.
If not used with other selectors, the default state is to be used with the * selector, for example, $(":header") is equivalent to $("*:header").

Example code:

Example 1:

The above code can set the text color in the title element whose class attribute value is qiantai to blue.

Example 2:

Copy code The code is as follows:

Front desk section



• html area


• div css area


• jQuery Zone


• Javascript Zone

Backstage area



• ASP Zone


• php area

Click to see the effect

Since the above code does not specify a selector to be used with the :header selector, it is used with the * selector by default. Therefore, the above code can set the text color of the title element in all elements in the current document to blue.

I hope this article will be helpful to everyone’s jQuery programming.
