javascript multi-level checkbox selection effect_form special effects

Today I finally figured out the effect of department multi-selection
See the picture:

First share the core code:
1: js script

Copy code The code is as follows:

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 = "";
treeHTML = option.text "
";
}
function dispKidsByPid(pid,degree) {
for (var i =0;iif (pid==checkList[i].parentid) {
dispCheck(checkList[i],degree);
dispKidsByPid(checkList[i] .id,degree 1);
}
}
}
function checkOption(option)
{
var deptCheckList=document.getElementsByName("deptOption");
/ /Check the parent element
if(option.parentId!=0){
var parentChecked="0";
for(var i=0;iif (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");
//Check child elements
for(var i=0;iif("dept_" deptCheckList[i].parentId== option.id){
deptCheckList[i].checked=option.checked;
checkSubOption(deptCheckList[i]);
}
}
}

Copy code The code is as follows:
