In jQuery: last selector usage example_jquery

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

This selector matches the last element in a collection of elements.

Grammar structure:

Copy code The code is as follows:

$(":last")

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:last").css("color","green" )

The above code can set the font color in the last li element in the li element collection to green.
If not used with other selectors, the default state is to be used with the * selector , for example, $(":last") is equivalent to $("*:last").

Example code:

Example 1:

Copy code The code is as follows:

The above code can set the font color in the last li element in the li element collection to green.

Example 2:

Since there is no specified selector to match the :last selector, it will be used to match the * selector by default, so the font color in the button button will be set to green.
