Append () Inserts the specified content in front of the end tag of the selected element (that is, the interior of the selected element). 
<HTML> 　　 <Head> 　　　　 <Scripttype= "Text/javascript"src= "/jquery/jquery.js"></Script> 　　　　 <Scripttype= "Text/javascript">
$ (). Ready (function() {$ ("Button"). Click (function() {$ ("span"). Append ("<a href="#">ddddd</a>")})
})</Script> </Head><Body>    <span>Aaaaaaaaaaaaaaa</span><Button>After function</Button></Body></HTML>

The results are as follows:

<span>aaaaaaaaaaaaaaa<a href= "#" >ddddd</a></span>
More than one a tag inside the span tag

After () inserts the specified content after the end tag of the selected element (that is, outside of the selected element). 
<HTML>    <Head>        <Scripttype= "Text/javascript"src= "/jquery/jquery.js"></Script> 　　　　  <Scripttype= "Text/javascript">$ (). Ready (function() {$ ("Button"). Click (function() {$ ("span"). After ("<a href="#">ddddd</a>")})
})</Script></Head><Body>    <span>Aaaaaaaaaaaaaaa</span><Button>After function</Button></Body></HTML>

The results are as follows:

<span>aaaaaaaaaaaaaaa</span>
<a href= "#" >ddddd</a>

The span tag has one more a tag behind it.

AppendTo () still inserts the specified content in front of the end tag of the selected element (that is, the interior of the selected element), except that the jquery function does not have the same wording. 
<HTML> 　　 <Head> 　　　　 <Scripttype= "Text/javascript"src= "/jquery/jquery.js"></Script> 　　　　 <Scripttype= "Text/javascript">
$ (). Ready (function() {$ ("Button"). Click (function() {//$ ("span"). AppendTo ("<a href=" # ">ddddd</a>"), so the wording is incorrect　　　　　　　　 　　 $("<a href="#">ddddd</a>"). AppendTo ("span") 　　　　　　　})
})</Script></Head><Body> 　　 <span>Aaaaaaaaaaaaaaa</span><Button>After function</Button></Body></HTML>

The results are as follows:

<span>aaaaaaaaaaaaaaa<a href= "#" >ddddd</a></span>
More than one a tag inside the span tag

The effect is the same as the APPEND function, except that they are written in the opposite way.

The difference between pretend () and before () is the same as the difference between append () and after ().
