使用了技术有： bootstrap、 jstree、 font-awesome 、jquery

这些可以到官网去下：下面会给链接的

需要ajax 动态获取后台属性菜单的json数据请看下面：

把core下的data改成如下。

"data" : function(obj, callback) {
$.ajax({
type : "POST",
url : "/treeviewisjstree/JSTreeServlet",
dataType : "json",
async : false,
success : function(result) {
console.info(result);
if (result) {
callback.call(this, result);
} else {
$("#jstree_div").html("暂无数据！");
}
}
});
}

json数据的格式：

[
{
"id": "ajson1", //id
"parent": "#", // 父节点 #标识这个是根节点
"text": "Simple root node", //显示的文本
"a_attr":{
"href":"链接",
"id": 1
},
"li_attr": {
"href":"属性",
"id": 2
},
"state" :{ //启动状态
"opened" : false,
"disabled" : false,
"selected" : true
}
}, {
"id": "ajson2",
"parent": "#",
"text": "Root node 2"
}, {
"id": "ajson3",
"parent": "ajson1",
"icon" : "fa fa-file",
"text": "Child 1"
}, {
"id": "ajson4",
"parent": "ajson2",
"icon" : "fa fa-file",
"text": "Child 2"
}, {
"id": "ajson6",
"parent": "ajson4",
"icon" : "fa fa-file",
"text": "Child 6"
}, {
"id": "ajson5",
"parent": "ajson4",
"icon" : "fa fa-file",
"text": "Child 5"
}, {
"id": "ajson7",
"parent": "ajson4",
"icon" : "fa fa-file",
"text": "Child 7"
}
]
