+---
+<p><strong><code>Range.setEnd()</code></strong>方法用于设置 <a href="https://developer.mozilla.org/zh-CN/docs/Web/API/Range" title="Range表示包含节点和部分文本节点的文档片段。"><code>Range</code></a>的结束位置。</p>
+
+<p> </p>
+
+<p>如果结束节点类型是 <code>Text</code>， <code>Comment</code>, or <code>CDATASection</code>之一, 那么 <code>endOffset指的是</code>从结束节点算起字符的偏移量。 对于其他 <code>Node</code> 类型节点， <code>endOffset</code>是指从结束结点开始算起子节点的偏移量。</p>
+
+<p>如果设置的结束点在起始点之上（在文档中的位置），将会导致选区折叠，起始点和结束点都会被设置为指定的结束位置。</p>
