在本教程中,我们将看到jQuery after和InsertAdter方法。
两者都执行相同的任务,在每个选定的元素后插入文本或者html,但语法是完全不同的。
after()的语法:
$("selectors").after("element to be inserted") ;
Example :
$("div").after("");
InsertAfter()语法:
$("element to be inserted") .insertAfter("selectors");
Example:
$("element to be inserted").insertAfter("div");
让我们通过示例来理解:
<!doctype>
<html>
<head>
<title>Jquery after and insertAfter example example </title>
<script src="http://code.jquery.com/jquery-2.2.3.min.js"></script>
</head>
<h2>Jquery after and insertAfter example example</h2>

.red{
border:3px dotted red;
color:red;
font-family: arial narrow;
}
.blue{
border:3px dotted red;
color:blue;
font-family: arial narrow;
}
</style>
<script type="text/javascript">
$(document).ready(function(){
$("#afterButton").click(function(){
$("div").after("inserting using after");
});
$("#insertAfterButton").click(function(){
$("inserting using insertAfter").insertAfter("div");
});
$("#reset").click(function(){
location.reload();
});
});
</script>
<body>
