function onClick(event, treeDemo, zNodes) {

		if(!zNodes.isParent){

	    alert( zNodes.id+"***"+zNodes.name);

			}

	};

	var setting = {

			dataType:"json",

		callback: {

			onClick: onClick

		},

		async: {

	        dataFilter: function (zNodes) {

	            eval(zNodes);///////

	            alert( eval(zNodes));

	            return nodes.children;////////

	        }

		}

	};

		

	

		var zNodes;

		var str = <%=request.getAttribute("str").toString()%>;

		zNodes = str;

		$(document).ready(function(){

			setting.async. dataFilter;

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

		});

传递 str数据为 [{"children":[{"children":[{"children":[],"open":true,"orgId":4,"orgName":"分1部门1"},{"children":[],"open":true,"orgId":5,"orgName":"分1部门2"}],"open":true,"orgId":2,"orgName":"分1"},{"children":[{"children":[],"open":true,"orgId":6,"orgName":"分2部门1"},{"children":[],"open":true,"orgId":7,"orgName":"分2部门3"}],"open":true,"orgId":3,"orgName":"分2"},{"children":[],"open":true,"orgId":8,"orgName":"分3"},{"children":[{"children":[],"open":true,"orgId":12,"orgName":"分3部门1"}],"open":true,"orgId":9,"orgName":"分3"},{"children":[{"children":[],"open":true,"orgId":11,"orgName":"分4部门1"}],"open":true,"orgId":10,"orgName":"分4"},{"children":[{"children":[],"open":true,"orgId":14,"orgName":"分5部门1"}],"open":true,"orgId":13,"orgName":"分5"},{"children":[],"open":true,"orgId":15,"orgName":"分6"}],"open":true,"orgId":1,"orgName":"总公司"}]

dataFilter: function (zNodes) { eval(zNodes);/////// alert( eval(zNodes)); return nodes.children;//////// } ================改成以下试一下================ dataFilter:function (treeId, parentNode, childNodes) { return childNodes; }

上面那代码是我们案例里使用的写法。 1.你先确定一下能不能正常返回json数据。 2.你返回的数据我觉得是不是多了父节点了，也就是说返回的数据应该是：[ {"children":[ {"children":[], "open":true, "orgId":4, "orgName":"分1部门1"}, {"children":[], "open":true, "orgId":5, "orgName":"分1部门2"} ], "open":true, "orgId":2, "orgName":"分1"}, {"children":[ {"children":[], "open":true, "orgId":6, "orgName":"分2部门1"}, {"children":[], "open":true, "orgId":7, "orgName":"分2部门3"} ], "open":true, "orgId":3, "orgName":"分2"}, {"children":[], "open":true, "orgId":8, "orgName":"分3"}, {"children":[ {"children":[], "open":true, "orgId":12, "orgName":"分3部门1"} ], "open":true, "orgId":9, "orgName":"分3"}, {"children":[ {"children":[], "open":true, "orgId":11, "orgName":"分4部门1"} ], "open":true, "orgId":10, "orgName":"分4"}, {"children":[ {"children":[], "open":true, "orgId":14, "orgName":"分5部门1"} ], "open":true, "orgId":13, "orgName":"分5"}, {"children":[], "open":true, "orgId":15, "orgName":"分6"} ] 把“总公司”部分删除试试。
