使用插件,第一步依然是引入:



<link rel="stylesheet" href="zTreeStyle/zTreeStyle.css" type="text/css">  
<script type="text/javascript" src="jquery-1.4.4.min.js"></script>  
<script type="text/javascript" src="jquery.ztree.all.js"></script>



 //详细的引入请参见API——如果有较多地方需要引入,请将引入部分抽取为专门的JSP页面,使用 <include />,例如,引入的页面:



<link href="${ctxStatic}/treeTable/themes/vsStyle/treeTable.min.css" rel="stylesheet" type="text/css" />
<script src="${ctxStatic}/treeTable/jquery.treeTable.min.js" type="text/javascript"></script>



    如何引入:



<%@include file="/WEB-INF/views/include/treeview.jsp" %>



  接下来看实例:



zTreeObj = $.fn.zTree.init($("#treeDemo"), setting, zNodes);



大致分析:

其中,$.fn.zTree.init为初始化树的方法,它接收三个参数,第一个为ztree的DOM容器,通常为 <ul> 或 <div>,例如:



<ul id="treeDemo" class="ztree"></ul>
<div id="ztree" class="ztree"></div>



//请务必设置class为 ztree,以指定为ztree的容器。

  第二个参数为ztree的配置,用于显示树的显示样式,例如:



// zTree 的参数配置,深入使用请参考 API 文档(setting 配置详解)
var setting = {};



//详细配置后续补充

  第三个参数为ztree的数据源,格式为JSON:



var zNodes = [  
  {name:"test1", open:true,"checked":"true", children:[  
     {name:"test1_1","checked":"true"}, {name:"test1_2"}]},  
  {name:"test2", open:true, children:[  
     {name:"test2_1"}, {name:"test2_2"}]}  
  ];



这样,一个最简单的树便可以加载了:

jquery ztree 选中状态 jquery ztree api_数据库_03

【使用开关函数隐藏与显示】:



$(".a").click(function(){
    $("p").toggle()
})



 

引用网友的理解:zTree的实现就是用setting把树的模型结构定义好,然后用zNodes当数据源,把数据浇灌到这个树

 settings实例:



var setting = {data:{simpleData:{enable:true,idKey:"id",pIdKey:"pId",rootPId:'0'}},
            callback:{onClick:function(event, treeId, treeNode){
                    var id = treeNode.pId == '0' ? '' :treeNode.pId;
                    $('#officeContent').attr("src","${ctx}/sys/office/list?id="+id+"&parentIds="+treeNode.pIds);
                }
            }
        };



查阅API可以得知:(回调函数部分这里暂时不进行展开,可以参见官网API)

    其中,simpleData的作用:不需要用户再把数据库中取出的 List 强行转换为复杂的 JSON 嵌套格式,这样,我们就可以使用简单的JSON格式,通过在JSON中指定id,pid来确定ztree的结构关系,而不用通过复杂的JSON嵌套来确定树的关系:



var setting = {
    data: {
        simpleData: {
            enable: true,
            idKey: "id",
            pIdKey: "pId",
            rootPId: 0
        }
    }
};
var treeNodes = [
    {"id":1, "pId":0, "name":"test1"},
    {"id":11, "pId":1, "name":"test11"},
    {"id":12, "pId":1, "name":"test12"},
    {"id":111, "pId":11, "name":"test111"}
];



 效果如下:
