1、附加点击事件：
TreeView1.Attributes.Add("onclick", "CheckEvent()");
2、JS脚本：
function public_GetParentByTagName(element, tagName) {
var parent = element.parentNode;
var upperTagName = tagName.toUpperCase();
//如果这个元素还不是想要的tag就继续上溯
while (parent && (parent.tagName.toUpperCase() != upperTagName)) {
parent = parent.parentNode ? parent.parentNode : parent.parentElement;
}
return parent;
}
//设置节点的父节点Cheched——该节点可访问，则他的父节点也必能访问
function setParentChecked(objNode) {
var objParentDiv = public_GetParentByTagName(objNode, "div");
if (objParentDiv == null || objParentDiv == "undefined") {
return;
}
var objID = objParentDiv.getAttribute("ID");
objID = objID.substring(0, objID.indexOf("Nodes"));
objID = objID + "CheckBox";
var objParentCheckBox = document.getElementById(objID);
if (objParentCheckBox == null || objParentCheckBox == "undefined") {
return;
}
if (objParentCheckBox.tagName != "INPUT" && objParentCheckBox.type == "checkbox")
return;
objParentCheckBox.checked = true;
setParentChecked(objParentCheckBox);
}
//设置节点的子节点uncheched——该节点不可访问，则他的子节点也不能访问
function setChildUnChecked(divID) {
var objchild = divID.children;
var count = objchild.length;
for (var i = 0; i < objchild.length; i++) {
var tempObj = objchild[i];
if (tempObj.tagName == "INPUT" && tempObj.type == "checkbox") {
tempObj.checked = false;
}
setChildUnChecked(tempObj);
}
}
//设置节点的子节点cheched——该节点可以访问，则他的子节点也都能访问
function setChildChecked(divID) {
var objchild = divID.children;
var count = objchild.length;
for (var i = 0; i < objchild.length; i++) {
var tempObj = objchild[i];
if (tempObj.tagName == "INPUT" && tempObj.type == "checkbox") {
tempObj.checked = true;
}
setChildChecked(tempObj);
}
}
//触发事件
function CheckEvent() {
var objNode = event.srcElement;
if (objNode.tagName != "INPUT" || objNode.type != "checkbox")
return;
if (objNode.checked == true) {
setParentChecked(objNode);
var objID = objNode.getAttribute("ID");
var objID = objID.substring(0, objID.indexOf("CheckBox"));
var objParentDiv = document.getElementById(objID + "Nodes");
if (objParentDiv == null || objParentDiv == "undefined") {
return;
}
setChildChecked(objParentDiv);
}
else {
var objID = objNode.getAttribute("ID");
var objID = objID.substring(0, objID.indexOf("CheckBox"));
var objParentDiv = document.getElementById(objID + "Nodes");
if (objParentDiv == null || objParentDiv == "undefined") {
return;
}
setChildUnChecked(objParentDiv);
}
}
还有点问题，点击取消时上级不会取消，没有半选状态
