|

<p>The <code><a href="/after">.after()</a></code>和<code>.insertAfter()</code> 实现同样的功能。主要的不同是语法——特别是（插入）内容和目标的位置。
|
||
对于 <code> .after()</code>, 选择表达式在函数的前面，参数是将要插入的内容。对于 <code>.insertAfter()</code>, 刚好相反，内容在方法前面，它将被放在参数里元素的后面。</p>

<p>请看下面的HTML：</p>

|

|

</div>
|
||
<p>我们可以创建内容然后同时插在好几个元素后面：</p>
|
||
<div class="syntaxhighlighter javascript nogutter">
|
||
<table>
|
||

|
||
<tr>
|
||
<td class="gutter">
|

<div class="line n1">1</div>

</td>
|

<td class="code">
|
||
<pre><div class="container"><div class="line"><code>$(<span class="string">'<p>Test</p>'</span>).insertAfter(<span class="string">'.inner'</span>);</code></div></div></pre>
|
||
</td>
|
||
</tr>
|
||
</tbody>
|
||
</table>
|
||
</div>
|
||
<p>结果如下：</p>
|

<div class="syntaxhighlighter xml nogutter">

|

|

|

|

</div>
|
||
<p>我们也可以在页面上选择一个元素然后插在另一个元素后面：</p>
|
||
<div class="syntaxhighlighter javascript nogutter">
|
||
<table>
|
||
<tbody>
|
||
<tr>
|
||
<td class="gutter">
|
||
<div class="line n1">1</div>
|
||
</td>
|
||
<td class="code">
|
||
<pre><div class="container"><div class="line"><code>$(<span class="string">'h2'</span>).insertAfter($(<span class="string">'.container'</span>));</code></div></div></pre>
|
||
</td>
|
||
</tr>
|
||
</tbody>
|
||
</table>
|
||
</div>
|
||
<p>如果一个被选中的元素被插在另外一个地方，它将被移动到目标元素的后面，注意是移动而不是复制：</p>
|
||
<div class="syntaxhighlighter xml nogutter">
|

|

<p>如果有多个目标元素，会将克隆拷贝插入的元素，插入到每个目标元素的后面，然后返回新集合（原始元素和克隆元素）。</p>
|
||
<p><strong>jQuery 1.9之前,</strong> 追加到单元素的情况下
|
||
没有创建一个新的集合，而返回原来的集合，当使用一个未知个数的元素时，这使我们难以使用<code>.end()</code>方法。</p>
