jquery的树形控件ztree怎么用?怎么导入?

还有比这个更详细的吗？ztree-demo

1.引入库文件
2.写配置文件 ，比如

var setting = {
    data: {
        simpleData: {
            enable: true
        }
    }
};

var zNodes =[
    { id:1, pId:0, name:"父节点1 - 展开", open:true},
    { id:11, pId:1, name:"父节点11 - 折叠"},
    { id:111, pId:11, name:"叶子节点111"},
    { id:112, pId:11, name:"叶子节点112"},
    { id:113, pId:11, name:"叶子节点113"},
    { id:114, pId:11, name:"叶子节点114"},
    { id:12, pId:1, name:"父节点12 - 折叠"},
    { id:121, pId:12, name:"叶子节点121"},
    { id:122, pId:12, name:"叶子节点122"},
    { id:123, pId:12, name:"叶子节点123"},
    { id:124, pId:12, name:"叶子节点124"},
    { id:13, pId:1, name:"父节点13 - 没有子节点", isParent:true},
    { id:2, pId:0, name:"父节点2 - 折叠"},
    { id:21, pId:2, name:"父节点21 - 展开", open:true},
    { id:211, pId:21, name:"叶子节点211"},
    { id:212, pId:21, name:"叶子节点212"},
    { id:213, pId:21, name:"叶子节点213"},
    { id:214, pId:21, name:"叶子节点214"},
    { id:22, pId:2, name:"父节点22 - 折叠"},
    { id:221, pId:22, name:"叶子节点221"},
    { id:222, pId:22, name:"叶子节点222"},
    { id:223, pId:22, name:"叶子节点223"},
    { id:224, pId:22, name:"叶子节点224"},
    { id:23, pId:2, name:"父节点23 - 折叠"},
    { id:231, pId:23, name:"叶子节点231"},
    { id:232, pId:23, name:"叶子节点232"},
    { id:233, pId:23, name:"叶子节点233"},
    { id:234, pId:23, name:"叶子节点234"},
    { id:3, pId:0, name:"父节点3 - 没有子节点", isParent:true}
];
$(document).ready(function(){   //初始化
        $.fn.zTree.init($("#treeDemo"), setting, zNodes);//#treeDemo就是你要填树形结构的容器
    });

看了你评论里的代码，才知道。
zTree 的容器 className 别忘了设置为 "ztree"！！！

<div id='treeDemo'  class="ztree"> a</div>
