There are implicit iterations in jquery, so we don't need to manipulate some elements again. But if different elements are involved and have different operations, you need to do each traversal. This paper uses 10 cases of li setting different transparency to illustrate the each method.

Syntax:

$(element) .each (function (index,element) {})

Parameter index: represents the element index, which in this case is 0-9

Parameter element: represents the object, in this case each li

Case effect:

The code is as follows

Li {width: 100px; height: 100px; background-color: green; list-style: none; float: left; margin-left: 10px } $(function () {/ / page load, change the transparency of each li $("li") .each (function (index,element) {/ / the first parameter is the index, the second parameter is the object $(element) .css ("opacity", (index+1) / 10);})}) 1 2 3 4 5 6 7 7 8 9 10 this is the end of the introduction to "how to use the each () method in jQuery".
