从后台传过来id,怎么默认选取节点 我找了api找了好久@zTreeAPI

var treeObj = $.fn.zTree.getZTreeObj("utreeDemo");
treeObj.checkAllNodes(false);
var listTr = datagrid.FSystemMenu.split(",");
for(var i=0, l=listTr.length; i < l; i++){
var nd = treeObj.getNodeByParam("id",listTr[i],null);
if(nd){
treeObj.checkNode(nd,true,false);
}
多看看api
