Question

<script language="javascript">
 $(function() {
   var select_value="";
  function zTreeOnDblClick(event, treeId, treeNode) {
   if(null!=treeNode.otherParam){
    $("#choices > option").each(function (i){
     select_value+=$(this).val();
    });
    if(-1==select_value.indexOf(treeNode.otherParam)){
        $("#choices").append("<option id='"+treeNode.id+"' value='"+treeNode.otherParam+"'>"+treeNode.name+"</option>");
    }
   }
  };
   var setting = {
    data : {
     simpleData : {
      enable : true
     }
    },
    isSimpleData : true,
    callback: {
     onDblClick: zTreeOnDblClick
    }
   };

   var zNodes = [
   {id : 1,pId : 0,name : "组织架构",open : true}
   <%
    List<UmDepartinfo> departlist= (List<UmDepartinfo>)request.getAttribute("DepartList");
    if(null!=departlist&&departlist.size()>0){
     for(UmDepartinfo u:departlist){

Answer 1

参考 http://www.ztree.me/v3/demo.php#_502  配置成 异步加载模式就可以了

Answer 2

异步加载，setting里面有async属性，配置一下即可
