zTree树节点代码讲解

下面贴一些自己敲的代码，在文档中都介绍的很清楚，每一项都能找到，我就不备注了。

$(document).ready(function(){

ansyTree();

$("#submitForm").click(function(){

var nodes = treeObj.getCheckedNodes(true);

if(nodes.length==0){

$.messager.alert('提示','请选择要分配的资源....' );

return ;

}

var mdId="";

for(var i=0;i if(nodes[i].id!='0')

mdId+=","+nodes[i].id;

}

$.ajax({

type : 'post',

url:parent.basePath+'server/role/insertRoleModule.do',

dataType:"json",

data:{

ROLE_ID:roleId,

MD_ID:mdId.substr(1)

},

success: function (retVal) {//回调函数

$.messager.alert('提示',retVal.message);

},

beforeSend:function(){

$.messager.progress({title : '提示', text : '数据处理中，请稍后....'});

},

complete :function(){

$.messager.progress('close');

}

});

});

});

var treeObj;

function ansyTree(){

var rootNode = [

{id:0,"name":"系统菜单(根目录)",isParent:true, open:true}

]

treeObj= $.fn.zTree.init($("#treeDemo"), {

treeId:'moduleTree',

async: {

enable: true,

url : parent.basePath+'server/role/selectRoleModuleTree.do',

type:"post",

autoParam: ["id=PM_ID"],

otherParam: {"ROLE_ID":roleId},

dataFilter: null

},

callback: {

onAsyncSuccess:function(event, treeId, treeNode, msg){

expandNodes(treeNode.children);

}

},

view: {

dblClickExpand: false

},

check: {

enable: true

}

},rootNode);

expandNodes(treeObj.getNodes());

}

function expandNodes(nodes){

if (!nodes) return;

for (var i=0, l=nodes.length; i treeObj.expandNode(nodes[i], true, false, false);

}

}
