JQuery ZTree简单使用
@(JavaScript)[jQuery, ztree, 入门]
基本概述
zTree 是一个依靠 jQuery 实现的多功能 “树插件”。优异的性能、灵活的配置、多种功能的组合是 zTree 最大优点。专门适合项目开发，尤其是 树状菜单、树状数据的Web显示、权限管理等等。
zTree 是开源免费的软件（MIT 许可证）。在开源的作用下，zTree 越来越完善，目前已经拥有了不少粉丝，并且今后还会推出更多的 zTree 扩展功能库，让 zTree 更加强大。 ——参考《百度百科》
官网：zTree官网
PS：zTree的官方API文档和demo挺详细的，值得一读。
案例
使用标准json数据构造ztree
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>ztree测试</title>
<link rel="stylesheet" type="text/css" href="${pageContext.request.contextPath}/js/easyui/themes/default/easyui.css">
<link rel="stylesheet" type="text/css" href="${pageContext.request.contextPath}/js/easyui/themes/icon.css">
<script type="text/javascript" src="/UploadFiles/2021-04-02/jquery-1.8.3.js">
使用简单json数据构造ztree
<div data-options="iconCls:'icon-remove'" title="功能菜单">
<ul id="ztree2" class="ztree"></ul>
</div>
<!-- 使用简单json数据构造ztree -->
<script type="text/javascript">
$(function() {
var setting = {
data: {
simpleData: {
enable: true
}
}
};
var zNodes = [
{"id":1, "pId":0, "name":"test1"},
{"id":11, "pId":1, "name":"test11"},
{"id":12, "pId":1, "name":"test12"},
{"id":111, "pId":11, "name":"test111"},
{"id":2, "pId":0, "name":"test2"},
{"id":3, "pId":0, "name":"test3"},
{"id":31, "pId":2, "name":"test31"}
];
$.fn.zTree.init($("#ztree2"), setting, zNodes);
});
</script>
发送ajax请求获取动态json数据构造ztree
json内容
[
{ "id":"11", "pId":"0", "name":"菜单1"},
{ "id":"111", "pId":"11", "name":"菜单11", "page":"xx.action"},
{ "id":"112", "pId":"11", "name":"菜单12","page":"xx.action"},
{ "id":"113", "pId":"11", "name":"菜单13", "page":"xx.action"},
{ "id":"114", "pId":"11", "name":"菜单14","page":"xx.action"},
{ "id":"12", "pId":"0", "name":"菜单2"},
{ "id":"121", "pId":"12", "name":"菜单21" ,"page":"xx.action"},
{ "id":"122", "pId":"12", "name":"菜单22" ,"page":"xx.action"},
{ "id":"123", "pId":"12", "name":"菜单23" ,"page":"xx.action"},
{ "id":"13", "pId":"0", "name":"菜单3"},
{ "id":"131", "pId":"13", "name":"菜单31","page":"xx.action"},
{ "id":"132", "pId":"13", "name":"菜单32","page":"xx.action"}
]
html片段
<div data-options="iconCls:'icon-remove'" title="非功能菜单">
<ul id="ztree3" class="ztree"></ul>
</div>
<!-- 发送ajax请求获取动态json数据构造ztree -->
<script type="text/javascript">
$(function() {
var setting = {
data: {
simpleData: {
enable: true
}
}
};
$.ajax({
url:'${pageContext.request.contextPath}/json/menu.json',
type:'get',
data:'',
dataType:'json',
success:function (data) {
$.fn.zTree.init($("#ztree3"), setting, data);
}
});
});
</script>
为ztree节点绑定事件动态添加选项卡
json内容
[
{ "id":"11", "pId":"0", "name":"菜单1"},
{ "id":"111", "pId":"11", "name":"菜单11", "page":"xx.action"},
{ "id":"112", "pId":"11", "name":"菜单12","page":"xx.action"},
{ "id":"113", "pId":"11", "name":"菜单13", "page":"xx.action"},
{ "id":"114", "pId":"11", "name":"菜单14","page":"xx.action"},
{ "id":"12", "pId":"0", "name":"菜单2"},
{ "id":"121", "pId":"12", "name":"菜单21" ,"page":"xx.action"},
{ "id":"122", "pId":"12", "name":"菜单22" ,"page":"xx.action"},
{ "id":"123", "pId":"12", "name":"菜单23" ,"page":"xx.action"},
{ "id":"13", "pId":"0", "name":"菜单3"},
{ "id":"131", "pId":"13", "name":"菜单31","page":"xx.action"},
{ "id":"132", "pId":"13", "name":"菜单32","page":"xx.action"}
]
html文件
<div data-options="iconCls:'icon-save'" title="ztree事件">
<ul id="ztree4" class="ztree"></ul>
</div>
<!-- 为ztree节点绑定事件动态添加选项卡 -->
<script type="text/javascript">
$(function() {
var setting = {
