Java一个组织树里边增加一个节点，然后把另一个节点下面的数据放在新创建的这个节点里。如何实现

</script>

    <!--表格树js -->

    <script>

        $(function(){

              

            var setting = {

               

                view:{showLine:true, showIcon: false}, //有没有连线和显不示显示图标

               //下面语句可以让pid相同的分层

                data: {

                    simpleData: {

                        enable: true //自动成圣树结构

                    }

                },

                callback: {

            onClick: zTreeOnClick //回调点击函数

        }

            }    

           

            //动态获取数据自动生成树

            $.ajax({

                type: "post",

                url: "../tools/admin_ajax.ashx?action=GetCallContent&time=" + Math.random(),//链接地址

                dataType: "html",

                success: function (data) {

                    //转换一下json

                    var zNodes = []

                  //  alert(myNodes)

                    for (var i = 0 i < myNodes.length i++) {    //判断                 

                        if (myNodes[i].open != null) {

                            if (myNodes[i].checked != null && myNodes[i].checked )

方法很简单。插件中是将数据写死在js里面的。只要是这个格式即可。所以在你从后台把数据从数据库读取出来后。按照tree需要的这个格式，把数据拼接成这个格式。通过ajax传回前台再调用绑定方法即可。

读取数据-组成需要的格式-传到前台js中-再执行tree的绑定方法调用即可。
