复制代码 代码如下:
function onTreeNodeChecked() {
var ele = event.srcElement;
if (ele.type == 'checkbox') {
var childrenDivID = ele.id.replace('CheckBox', 'Nodes');
var div = document.getElementById(childrenDivID);
if (div != null) {
var checkBoxs = div.getElementsByTagName('INPUT');
for (var i = 0; i < checkBoxs.length; i++) {
if (checkBoxs[i].type == 'checkbox')
checkBoxs[i].checked = ele.checked;
}
}
onTreeNodeChildChecked(ele);
}
}
function onTreeNodeChildChecked(ele) {
//自动处理上级
var parentDiv = ele.parentElement.parentElement.parentElement.parentElement.parentElement;
var parentChkBox = document.getElementById(parentDiv.id.replace('Nodes', 'CheckBox'));
