❮ 上一个 ❮ 元素对象 参考 下一个 ❯

示例

设置元素的外部文本

document.getElementById("myH1").outerText = "Changed content!";
自己试试 »

描述

outerText 属性设置或返回指定节点的文本内容。

此属性类似于内部 innerText 属性，实际上 获取 outerText 返回的结果与 获取 innerText 属性相同。

设置 元素的 outerText 时存在一个重要区别，因为元素本身将被删除。

提示： 还可以查看 outerHTML 属性。

浏览器支持

表中的数字指定完全支持该属性的第一个浏览器版本。

属性
outerText 43 11 不支持 6 61

语法

返回节点的文本内容

node.outerText

设置节点的文本内容（替换整个节点）

node.outerText = text

属性值

值 类型 描述
text 字符串 指定要插入的文本内容

技术细节

返回值 一个字符串，表示节点及其所有后代的文本内容
