javascript 多级checkbox选择效果

今天总算把部门多选的效果整出来
见图：

先共享核心代码：
1：js脚本


代码如下:

var treeHTML = "";
var checkList = new Array(); /*only init here*/
var barString = "└";/*┝└*/
var degreeString = "　";
function makeTree(id,text,value,parentid,isCheck) {
this.id = id;
this.text = text;
this.value = value;
this.parentid = parentid;
this.isCheck=isCheck;
}
function dispCheck(option,degree) {
for (var i=1;i<=degree;i++) {
treeHTML += degreeString;
}
treeHTML += barString;
treeHTML += "<input type='checkbox' name='deptOption' onclick='checkOption(this);checkSubOption(this)' id='dept_"+option.value+"' value='"+option.value+"' parentId='"+option.parentid+"' "+ option.isCheck+">";
treeHTML += option.text+"</input><br/>";
}
function dispKidsByPid(pid,degree) {
for (var i=0;i<checkList.length;i++) {
if (pid==checkList[i].parentid) {
dispCheck(checkList[i],degree);
dispKidsByPid(checkList[i].id,degree+1);
}
}
}
function checkOption(option)
{
var deptCheckList=document.getElementsByName("deptOption");
//检查父元素
if(option.parentId!=0){
var parentChecked="0";
for(var i=0;i<deptCheckList.length;i++){
if(deptCheckList[i].parentId==option.parentId){
if(deptCheckList[i].checked){
parentChecked="1";
break;
}
}
}
if(parentChecked=="1")
document.getElementById("dept_"+option.parentId).checked=true;
else
document.getElementById("dept_"+option.parentId).checked=false;
checkOption(document.getElementById("dept_"+option.parentId));
}
}
function checkSubOption(option){
var deptCheckList=document.getElementsByName("deptOption");
//检查子元素
for(var i=0;i<deptCheckList.length;i++){
if("dept_"+deptCheckList[i].parentId==option.id){
deptCheckList[i].checked=option.checked;
checkSubOption(deptCheckList[i]);
}
}
}
