ztree ajax初始化,ztree的初始化是怎样的机制?

var departmentTreeSetting = {

data: {

simpleData: {

enable: true,

idKey: "id",

pIdKey: "pid",

rootPId: 'ROOT'

}

},

async: {

enable: true,

type:"get",

url:"#{app.ctx.path}/rest/crm/department/#{param.companyUuid}?selectedDepartmentId=#{param.selecteddepartmentId}"

},

view: {

selectedMulti: false

},

check : {

autoCheckTrigger : false,

chkboxType : {"Y": "ps", "N": "ps"},

chkStyle : "checkbox",

enable : #{param.multiple ? true : false},

nocheckInherit : false,

radioType : "level"

},

callback: {

beforeClick: departmentTreeBeforeClick,

onClick: buildingTreeClick

}

};

$(document).ready(function(){

if(#{not empty param.companyUuid}){

buildingTree=$.fn.zTree.init($("#departmentTree"), departmentTreeSetting);

}

});

//-----------------------------

这样就能实现异步加载树节点功能，提高加载效率，其中url:"#{app.ctx.path}/rest/crm/department/#{param.companyUuid}?selectedDepartmentId=#{param.selecteddepartmentId}"为获部门节点nodes的json对象的服务，可自己修改。
