js树插件zTree获取所有选中节点数据的方法

本文实例讲述了js树插件zTree获取所有选中节点数据的方法。分享给大家供大家参考。具体分析如下：

由于刚接触Tree方面的东西。在网上看到了zTree，是中国人写的。所以API肯定是中文的。而且评论也很好。所以尝试用zTree在项目中。这个获取所有选中节点数据很简单。看一下API就能看懂了。所以我就直接上代码了。

代码如下:

<!DOCTYPE html>
<HTML>
<HEAD>
    <TITLE> ZTREE DEMO - Standard Data </TITLE>
    <meta http-equiv="content-type" content="text/html; charset=UTF-8">

        var setting = {   
            check:{
                enable:true
            },
            /*data: {
                simpleData: {
                    enable: true
                }
            }*/
            data:    {
                simpleData:{
                    enable:true
                }
            },
            callback:{
                onCheck:onCheck
            }
        };

var zNodes =[
            { id:1, pId:0, name:"随意勾选 1", open:false},
            { id:11, pId:1, name:"随意勾选 1-1", open:true},
            { id:111, pId:11, name:"随意勾选 1-1-1"},
            { id:112, pId:11, name:"随意勾选 1-1-2"},
            { id:12, pId:1, name:"随意勾选 1-2", open:true},
            { id:121, pId:12, name:"随意勾选 1-2-1"},
            { id:122, pId:12, name:"随意勾选 1-2-2"},
            { id:2, pId:0, name:"随意勾选 2",  open:false},
            { id:21, pId:2, name:"随意勾选 2-1"},
            { id:22, pId:2, name:"随意勾选 2-2", open:true},
            { id:221, pId:22, name:"随意勾选 2-2-1"},
            { id:222, pId:22, name:"随意勾选 2-2-2"},
            { id:23, pId:2, name:"随意勾选 2-13"}
        ];

$(document).ready(function(){
            $.fn.zTree.init($("#treeDemo"), setting, zNodes);
        });
            function onCheck(e,treeId,treeNode){
            var treeObj=$.fn.zTree.getZTreeObj("treeDemo"),
            nodes=treeObj.getCheckedNodes(true),
            v="";
            for(var i=0;i<nodes.length;i++){
            v+=nodes[i].name + ",";
            alert(nodes[i].id); //获取选中节点的值
            }
            }
        //-->
