1.EasyUI是什么?:

jQuery EasyUI是一组基于jQuery的UI插件集合体,而jQuery EasyUI的目标就是帮助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。

2.jQuery EasyUI有以下特点

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、支持HTML5(通过data-options属性)
5、开发产品时可节省时间和资源
6、简单,但很强大
7、支持扩展,可根据自己的需求扩展控件
8、目前各项不足正以版本递增的方式不断完善

4.Easyui的导入

我们使用一个框架首先我们要导入它的jar包和文件

5、引入必要的js和css样式文件

要想在页面中使用EasyUI,那么首先要做的就是在页面中引入必要js和css样式文件,以在jsp文件中使用EasyUI为例,文件引入的顺序如下所示:

<link rel="stylesheet" type="text/css" href="easyui/themes/default/easyui.css">   
<link rel="stylesheet" type="text/css" href="easyui/themes/icon.css">   
<script type="text/javascript" src="easyui/jquery-1.7.2.min.js"></script>   
<script type="text/javascript" src="easyui/jquery.easyui.min.js"></script>  

案例

1、通过layout布局

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>后台展示</title>
<link rel="stylesheet" type="text/css" href="${pageContext.request.contextPath }/static/js/public/easyui5/themes/default/easyui.css">   
<link rel="stylesheet" type="text/css" href="${pageContext.request.contextPath }/static/js/public/easyui5/themes/icon.css">   
<script type="text/javascript" src="${pageContext.request.contextPath }/static/js/public/easyui5/jquery.min.js"></script>   
<script type="text/javascript" src="${pageContext.request.contextPath }/static/js/public/easyui5/jquery.easyui.min.js"></script>  
</head>
<body class="easyui-layout">
	<div data-options="region:'north',border:false" style="height:60px;background:#B3DFDA;padding:10px">north region</div>
	<div data-options="region:'west',split:true,title:'West'" style="width:150px;padding:10px;">west content</div>
	<div data-options="region:'east',split:true,collapsed:true,title:'East'" style="width:100px;padding:10px;">east region</div>
	<div data-options="region:'south',border:false" style="height:50px;background:#A9FACD;padding:10px;">south region</div>
	<div data-options="region:'center',title:'Center'"></div>
</body>

</html>

2、通过tree(树形菜单)加载菜单

树形(tree)的结构目录 (tree_data1.json)

[{
	"id":1,
	"text":"菜单管理",
	"children":[{
		"id":11,
		"text":"财务",
		"state":"closed",
		"children":[{
			"id":111,
			"text":"日常报销"
		},{
			"id":112,
			"text":"Wife"
		},{
			"id":113,
			"text":"Company"
		}]
	},{
		"id":12,
		"text":"后勤",
		"children":[{
			"id":121,
			"text":"Intel"
		},{
			"id":122,
			"text":"费用缴纳",
			"attributes":{
				"p1":"Custom Attribute1",
				"p2":"Custom Attribute2"
			}
		},{
			"id":123,
			"text":"Microsoft Office"
		},{
			"id":124,
			"text":"Games",
			"checked":true
		}]
	},{
		"id":13,
		"text":"index.html"
	},{
		"id":14,
		"text":"about.html"
	},{
		"id":15,
		"text":"welcome.html"
	}]
}]

TreeNode(实体类)

package com.caoguangli.entity;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

/**
 * 作用是通过TreeNode类转成
 * tree——data1.json的字符串
 * @author Administrator
 *
 */
public class TreeNode {

	private String id;
	private String text;
	private List<TreeNode> children = new ArrayList<>();
    private Map<String, Object> attributes = new HashMap<>();
	
    
    public String getId() {
		return id;
	}
	public void setId(String id) {
		this.id = id;
	}
	public String getText() {
		return text;
	}
	public void setText(String text) {
		this.text = text;
	}
	public List<TreeNode> getChildren() {
		return children;
	}
	public void setChildren(List<TreeNode> children) {
		this.children = children;
	}
	public Map<String, Object> getAttributes() {
		return attributes;
	}
	public void setAttributes(Map<String, Object> attributes) {
		this.attributes = attributes;
	}
	public TreeNode(String id, String text, List<TreeNode> children, Map<String, Object> attributes) {
		super();
		this.id = id;
		this.text = text;
		this.children = children;
		this.attributes = attributes;
	}
	public TreeNode() {
		super();
	}
	@Override
	public String toString() {
		return "TreeNode [id=" + id + ", text=" + text + ", children=" + children + ", attributes=" + attributes + "]";
	}
    
    
}

MenuDao(继承JsonBaseDao)

package com.caoguangli.dao;

import java.sql.SQLException;

			sql += " and parentid=-1";

//		这里面存放的是数据库中的菜单信息

		return listMap;
	}
	
	/**

	private void mapToTreeNode(Map<String, Object> map, TreeNode treeNode) throws InstantiationException, IllegalAccessException, SQLException {

		for (Map<String, Object> map : listMap) {
			treeNode = new TreeNode();
			mapToTreeNode(map, treeNode);
			listTreeNode.add(treeNode);
		}
	}
}

MenuAction (继承ActionSupport )

package com.caoguangli.web;

import java.util.List;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import com.caoguangli.dao.MenuDao;
import com.caoguangli.entity.TreeNode;
import com.caoguangli.framework.ActionSupport;
import com.caoguangli.util.ResponseUtil;
import com.fasterxml.jackson.databind.ObjectMapper;

public class MenuAction extends ActionSupport {

	private MenuDao menuDao = new MenuDao();
	 
	public String menuTree(HttpServletRequest req,HttpServletResponse resp) {
		ObjectMapper om = new ObjectMapper();
		try {
//			获取到easyui框架所识别的json格式
			List<TreeNode> listTreeNode = this.menuDao.listTreeNode(req.getParameterMap(), null);
			ResponseUtil.write(resp, om.writeValueAsString(listTreeNode));
		} catch (Exception e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		return null;
		
	}
}

mvc.xml配置

<action path="/menuAction" type="com.caoguangli.web.MenuAction"></action>

index.js

$(function() {
	$('#tt').tree({    
    url:'menuAction.action?methodName=menuTree'   
});
})

界面效果:

3、Tabs(通过菜单去打开不同的tab页)

选项卡显示一批面板。但在同一个时间只会显示一个面板。每个选项卡面板都有头标题和一些小的按钮工具菜单,包括关闭按钮和其他自定义按钮。

<div data-options="region:'center',title:'Center'">
	   <div id="menuTab" class="easyui-tabs" style="width:500px;height:250px;">   
            <div title="首页" style="padding:20px;display:none;">欢迎界面</div>    
	</div>

index.jsp

$(function() {
	$('#tt').tree({    
	    url:'menuAction.action?methodName=menuTree',
	    	onClick: function(node){
	    		alert(node.text);  // 在用户点击的时候提示
	    		// add a new tab panel    $.extends
	    		var content = '<iframe scrolling="no" frameborder="0" src="'+node.attributes.menuURL+'" width="99%" height="99%"></iframe>';
	    		if($('#menuTab').tabs('exists',node.text)){
//	    			存在执行选项卡选中已有的选项卡操作
	    			$('#menuTab').tabs('select',node.text);
	    		}else{
//	    			不存在执行新增的操作
	    			$('#menuTab').tabs('add',{    
		    		    title:node.text,    
		    		    content:content,    
		    		    closable:true   
		    		}); 
	    		}    		
	    	}
	});  
})
