e3.1做一个部门树，根结点为部门，可生成的树根结点和子结点同级：
json数据：[{"id":-1,"open":true,"parentId":0,"name":"部门","isParent":true},{"id":2,"open":false,"parentId":-1,"name":"技术部","isParent":true},{"id":3,"open":false,"parentId":-1,"name":"销售部","isParent":true},{"id":4,"open":false,"parentId":-1,"name":"车间","isParent":true},{"id":1,"open":false,"parentId":-1,"name":"财务部","isParent":false}]，
js脚本：
var setting = {
async : {
enable : true,
url : "${pageContext.request.contextPath}/department/department.action",
autoParam : [ "id=id" ],
data : {
key : {
name : "name"
},
simpleData : {
enable : true,
idKey : "id",
pIdKey : "parentId",
rootPId : -1
}
} }
}; $(document).ready(function() {
$.fn.zTree.init($("#treeDemo"), setting);
});


自己解决了，是语法错误，感谢zTreeAPI 提供这么功能强大又好用的树var setting = {
async : {
enable : true,
url : "${pageContext.request.contextPath}/department/department.action",
autoParam : ["id=id"]
},
data : {
key : {
name : "name"
},
simpleData : {
enable : true,
idKey : "id",
pIdKey : "parentId",
rootPId : -1
}
}
}; $(document).ready(function() {
$.fn.zTree.init($("#treeDemo"), setting);
});
