64     function InitTree() {
65      var   treeObj = $.fn.zTree.getZTreeObj("treeDemo");
66         var ojecds = "<%=OJBCDS %>";
67       //  alert(ojecds);
68         var array = ojecds.split(",");
69         var node = null;
70         for (var i = 0; i < array.length; i++) {
71             node = treeObj.getNodeByParam("DEPTCD", array[i], null);
72              
73             treeObj.checkNode(node, true, false);
74             
75         }
76         
77     }

如上面的代码所示：

将initTree()函数放在A处事可以正常执行，若果放在B处就不能够正常的执行甚至出现异常或者报错；

分析：

可能是数据源采用异步加载的方式，整个执行的先后有影响吧；
