实现思路： 1、ztree中节点是通过一个json的Array作为数据源、，所以直接操作json字符串，然后转为json对象数组。 2、然后用新构成的json数组对象重新初始化ztree对象。 复制代码 代码如下: <BR> var zTreeObj1;<BR> var zTreeObj2;<BR> var leftDivStr = "[";<BR> var rightDivStr = "[";<BR> var setting = {<BR> edit: {<BR> enable: false,<BR> showRemoveBtn: false,<BR> showRenameBtn: false<BR> },<BR> data: {<BR> simpleData: {<BR> enable: true<BR> }<BR> },<BR> callback: {<BR> //onClick : menuOnClick<BR> }<BR> };<BR> function menuOnClick(event, treeId, treeNode, clickFlag) {<br><br> }<BR> //注册toSource函数，解决ie不支持Array的toSource()方法的问题<BR> Array.prototype.toSource = function (){<BR> var str = "[";<BR> for(var i = 0 ;i<this.length;i++){<BR> str+="{id:\""+this[i].id+<BR> "\",pId:\""+this[i].pId<BR> +"\",name:\""+this[i].name<BR> +"\",isParent:\""+this[i].isParent<BR> +"\",file:\""+this[i].file<BR> +"\",icon:\""+this[i].icon<BR> +"\",open:\""+this[i].open<BR> +"\"},";<BR> }<BR> if(this.length != 0){<BR> str = str.substring(0, str.length-1);<BR> }<BR> str +="]";<BR> return str; <P> } ;<BR> //注册unique函数，去掉array中重复的对象（id相同即为同一对象）<BR> Array.prototype.unique = function (){<BR> var r = new Array();<BR> label:for(var i = 0, n = this.length; i < n; i++) {<BR> for(var x = 0, y = r.length;
