<p><code><a href="/append">.append()</a></code>和<code>.appendTo()</code>两种方法功能相同，主要的不同是语法——内容和目标的位置不同。对于<code>.append()</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>.appendTo()</code>刚好相反，内容在方法前面，无论是一个选择器表达式
|
||
或创建作为标记上的标记，它都将被插入到目标容器的末尾。</p>

<p>请看下面的HTML:</p>

|

|

<p>我们可以创建内容然后同时插入到好几个元素里面：</p>
|
||
<div class="syntaxhighlighter javascript nogutter">
|

|
||

|
||

|

<td class="gutter">

<td class="code">
|

<pre><div class="container"><div class="line"><code>$(<span class="string">'<p>Test</p>'</span>).appendTo(<span class="string">'.inner'</span>);</code></div></div></pre>
|
||
</td>
|
||
</tr>
|
||
</tbody>
|
||
</table>
|
||
</div>
|
||
<p>每个新的inner <code><div></code> 元素会得到新的内容：</p>
|
||
<div class="syntaxhighlighter xml nogutter">

<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里面：</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>$(<span class="string">'h2'</span>).appendTo($(<span class="string">'.container'</span>));</code></div></div></pre>
|
||
</td>
|
||
</tr>
|
||
</tbody>
|
||
</table>
|
||
</div>
|
||
<p>如果这种方式选择的元素被插入到一个DOM中单一的位置的地方（注：文档中只有一个目标元素），它将被移动到目标中（不是克隆），并返回一组新的插入后的元素集合：</p>
|
||
<div class="syntaxhighlighter xml nogutter">

|

|

|

</table>
|

</div>
|
||
<p>如果有多个目标元素，内容将被复制然后按顺序插入到每个目标里面。新的集合（原始元素加克隆元素）被返回。</p>
