EasyUI入门 | 易学教程

jQueryEasyUI

jQuery EasyUI是一组基于jQuery的UI插件集合体,目标就是帮助web开发者更轻松的打造出功能丰富并且美观的UI界面。
开发者不需要编写复杂的javascript，也不需要对css样式有深入的了解，开发者需要了解的只有一些简单的html标签。
Query EasyUI 提供了用于创建跨浏览器网页的完整的组件集合，包括功能强大的 datagrid（数据网格）、treegrid（树形表格）、 panel（面板）、combo（下拉组合）等等。用户可以组合使用这些组件，也可以单独使用其中一个。

EasyUI特点

Query EasyUI为提供了大多数UI控件的使用，如：accordion，combobox，menu，dialog，tabs，validatebox，datagrid，window，tree等等。

特点：

基于jquery用户界面插件的集合
为一些当前用于交互的js应用提供必要的功能
EasyUI支持两种渲染方式分别为javascript方式（如：$('#p').panel({...})）和html标记方式（如：class="easyui-panel"）
开发产品时可节省时间和资源
简单，但很强大
支持扩展，可根据自己的需求扩展控件

EasyUI实例

layout布局

导入需要的外部资源文件（js和css）以及jar包

EasyUI实例所需要用到的jar文件

引入js文件和css文件

新建一个jsp页面在<head>引入js文件和css样式</head>（切记query.min.js一定得在jquery.easyui.min.js上，顺序不能颠倒）

 1 <head>
 2 <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
 3 <title>Insert title here</title>
 4 <!-- Ctrl+Shift+r -->
 5 <link rel="stylesheet" type="text/css" href="${pageContext.request.contextPath }/static/js/public/easyui5/themes/default/easyui.css">   
 6 <link rel="stylesheet" type="text/css" href="${pageContext.request.contextPath }/static/js/public/easyui5/themes/icon.css">  
 7 <script type="text/javascript" src="${pageContext.request.contextPath }/static/js/public/easyui5/jquery.min.js"></script>  
 8 <script type="text/javascript" src="${pageContext.request.contextPath }/static/js/public/easyui5/jquery.easyui.min.js"></script>   
 9 <script type="text/javascript" src="${pageContext.request.contextPath }/static/js/index.js"></script>   
10 </head>

效果图

通过树形菜单tree加载菜单和tabs(通过菜单去打开不同的tab页)

导入工具类

导入tree_data1.json文件

 1 [{
 2     "id":1,
 3     "text":"My Documents",
 4     "children":[{
 5         "id":11,
 6         "text":"Photos",
 7         "state":"closed",
 8         "children":[{
 9             "id":111,
10             "text":"Friend"
11         },{
12             "id":112,
13             "text":"Wife"
14         },{
15             "id":113,
16             "text":"Company"
17         }]
18     },{
19         "id":12,
20         "text":"Program Files",
21         "children":[{
22             "id":121,
23             "text":"Intel"
24         },{
25             "id":122,
26             "text":"Java",
27             "attributes":{
28                 "p1":"Custom Attribute1",
29                 "p2":"Custom Attribute2"
30             }
31         },{
32             "id":123,
33             "text":"Microsoft Office"
34         },{
35             "id":124,
36             "text":"Games",
37             "checked":true
38         }]
39     },{
40         "id":13,

42     },{
43         "id":14,
44         "text":"about.html"
45     },{
46         "id":15,
47         "text":"welcome.html"
48     }]
49 }]
