z-tree 回显所有选中的id

//回显选择的checkbox函数 function treeHxIdFun(obj) {     var objTree = $.fn.zTree.init($("#demo"), setting, nodes);     var zTreeObj = $.fn.zTree.getZTreeObj("demo");     var zTree = objTree.getCheckedNodes(false);     for(var i = 0; i < obj.length; i++){         zTreeObj.checkNode(zTreeObj.getNodeByParam("id", obj[i]));         zTreeObj.selectNode(zTreeObj.getNodeByParam("id", obj[i]));     }; };

obj =["34", "3", "34#add"] 数组，id 与树形的所有id 一致
