<p><a href="/zh-CN/docs/Web/HTML/Global_attributes" style="text-decoration: underline;">全局属性</a> <strong>draggable</strong> 是一个枚举类型的属性，用于标识元素是否允许使用 <a href="/zh-CN/docs/DragDrop/Drag_and_Drop" title="https://developer.mozilla.org/En/DragDrop/Drag_and_Drop">拖放操作 API</a> 拖动。它的取值如下：</p>

<ul>
 <li><span style="font-family: Courier New;">true，表示元素可以被拖动</span></li>
 <li><span style="font-family: Courier New;">false，表示元素不可以被拖动</span></li>
</ul>

<p>如果该属性没有设值，则默认值 为 <span style="font-family: Courier New;">auto ，表示使用浏览器定义的默认行为。</span></p>

<p>这个属性是<em>枚举类型</em>，而不是 <em>布尔类型</em> 。这意味着必须显式指定值为 <span style="font-family: Courier New;">true</span> 或者 <span style="font-family: Courier New;">false</span> ，像 <code>&lt;label draggable&gt;Example Label&lt;/label&gt; 这样的简写是不允许的。正确的用法是</code> <code>&lt;label draggable="true"&gt;Example Label&lt;/label&gt;。</code></p>

<p>默认情况下，只有已选中的文本、图片、链接可以拖动。对其它的元素来说，必须按拖动机制的顺序设置 <strong>ondragstart</strong> 事件才能正常工作， 见 <a href="/zh-CN/docs/DragDrop/Drag_Operations" title="https://developer.mozilla.org/En/DragDrop/Drag_Operations">综合示例</a> 。</p>
