<p><code><strong>HTMLSelectElement.remove()</strong></code> 方法从一个 select 元素中删除指定序数的 option 元素。没有传参时为删除当前元素本身：<a href="/en-US/docs/Web/API/ChildNode/remove">ChildNode.remove()</a>。</p>

<h2 id="语法">语法</h2>

<pre class="syntaxbox"><em>collection</em>.remove(<em>index</em>);
</pre>

<h3 id="参数">参数</h3>

<ul>
 <li><code>index</code><em> </em>是从 option {{ domxref("HTMLOptionElement") }} 集合中要移除元素的序数。如果序数对应的元素不存在，调用这个方法就没有任何效果。</li>
</ul>

<pre class="brush: js">var sel = document.getElementById("existingList");
sel.remove(1);

/*
  上面的代码会将下面的 select 元素结构：

  &lt;select id="existingList" name="existingList"&gt;
    &lt;option value="1"&gt;Option: Value 1&lt;/option&gt;
    &lt;option value="2"&gt;Option: Value 2&lt;/option&gt;
    &lt;option value="3"&gt;Option: Value 3&lt;/option&gt;
  &lt;/select&gt;

  变成这样：

  &lt;select id="existingList" name="existingList"&gt;
    &lt;option value="1"&gt;Option: Value 1&lt;/option&gt;
    &lt;option value="3"&gt;Option: Value 3&lt;/option&gt;
  &lt;/select&gt;
