HTML DOM previousSibling 属性

❮ Element 对象

实例

返回某节点之前紧跟的节点的HTML内容:

var x = document.getElementById("item2").previousSibling.innerHTML;
亲自试一试 »

定义和用法

previousSibling 属性返回同一树级别的指定节点的上一个节点。

返回的节点作为节点对象返回。

此属性与 previousElementSibling区别在于, previousSibling 将前一个同级节点作为元素节点、文本节点或注释节点返回,而 previousElementSibling 将前一个同级节点作为元素节点返回(忽略文本和注释节点)。

该属性是只读的。

提示: 使用 nextSibling 属性返回同一树级别的指定节点的下一个节点。

提示: 使用 childNodes 属性返回指定节点的任何子节点。
