调了 好几天的问题 treeview 的js 处理复选框之间的关系，选中子框父框自动选中，单独执行 没问题 放到框架页里 就有问题

刚开始的js 这么写的

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'));
    if (parentChkBox != null) {
        var ChildsChkAll = true;
        var Boxs = parentDiv.getElementsByTagName('INPUT');
        var m = 0;
        var n = 0;
        for (var i = 0; i < Boxs.length; i++) {

            if (Boxs[i].type == 'checkbox') {
                m++;
            }
            if (Boxs[i].type == 'checkbox' && Boxs[i].checked == false) {
                n++
            }
        }
        if (m == n) {

            ChildsChkAll = false;
        }
        parentChkBox.checked = ChildsChkAll;
        OnTreeNodeChildChecked(parentChkBox);
    }
}
    } 

　　然后 加了个catch 就完事了

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 
    try
    {
    var parentDiv = ele.parentElement.parentElement.parentElement.parentElement.parentElement;

    var parentChkBox = document.getElementById(parentDiv.id.replace('Nodes', 'CheckBox'));
    if (parentChkBox != null) {
        var ChildsChkAll = true;
        var Boxs = parentDiv.getElementsByTagName('INPUT');
        var m = 0;
        var n = 0;
        for (var i = 0; i < Boxs.length; i++) {

            if (Boxs[i].type == 'checkbox') {
                m++;
            }
            if (Boxs[i].type == 'checkbox' && Boxs[i].checked == false) {
                n++
            }
        }
        if (m == n) {

            ChildsChkAll = false;
        }
        parentChkBox.checked = ChildsChkAll;
        OnTreeNodeChildChecked(parentChkBox);
    }
}
    catch(e)
    {
    
    
    }
}
