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:

  1. 基于jquery用户界面插件的集合
  2. 为一些当前用于交互的js应用提供必要的功能
  3. 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")
  4. 开发产品时可节省时间和资源
  5. 简单,但很强大
  6. 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>

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)

导入之前的工具类

导入tree_data1.json文件

index.js文件

  • 存在执行选项卡选中操作
  • 不存在执行新增的操作
