js获取子元素 原生获取子元素

js原生获取子节点:

1.封装成公用方法,以便于复用.

function deleteTextNode(id) {var _elem = document.getElementById(id),_child = _elem.childNodes,i = 0;for (; i < _child.length; i++) {if (_child[i].nodeName === "#text") {_elem.removeChild(_elem.childNodes[i]);}}return _child;}

2.调用方法传入id获取到子元素.

var children = deleteTextNode("wrap");
