EasyUI Introduction

easyui is a collection of user interface plug-ins based on jQuery.

easyui provides the necessary functionality for creating modern, interactive, JavaScript applications.

Using easyui, you don’t need to write a lot of code. You only need to define the user interface by writing some simple HTML tags.

easyui is a complete framework that perfectly supports HTML5 web pages.

easyui saves the time and scale of your web development.

easyui is very simple but powerful.

In the process of backend management system development, the top and left layouts are the most common page layout method. Now let’s take a look at how to quickly build a usable page framework using easyui, the jquery front-end framework.

1. Introduce the files required by easyui into the page

<%-- 加载easyui的样式文件，bootstrap风格 --%>
<link href="${ctx }/css/themes/bootstrap/easyui.css" rel="stylesheet">
<link href="${ctx }/css/themes/icon.css" rel="stylesheet">
<%-- 加载jquery和easyui的脚本文件 --%>
<script src="${ctx }/js/jquery-easyui-../jquery.min.js"></script>
<script src="${ctx }/js/jquery-easyui-../jquery.easyui.min.js"></script>
<script src="${ctx }/js/jquery-easyui-../locale/easyui-lang-zh_CN.js"></script>

2. Build the necessary html structure in the body part of the page

<body>
<div id="home-layout">
<!-- 页面北部，页面标题 -->
<div data-options="region:'north'" style="height:50px;">
<!-- add your code -->
</div>
<!-- 页面西部，菜单 -->
<div data-options="region:'west',title:'菜单栏'" style="width:200px;">
<div class="home-west">
<ul id="home-west-tree"></ul>
</div>
</div>
<!-- 页面中部，主要内容 -->
<div data-options="region:'center'">
<div id="home-tabs">
<div title="首页">
<h2 style="text-align: center">欢迎登录</h2>
</div>
</div>
</div>
</div>
</body>

One thing to note here: when easyui uses layout, north and south need to specify the height, west and east need to specify the width, and center will automatically adapt to the height and width.

3. Use js to initialize the easyui component

I personally recommend using js code to initialize easyui components instead of using the data-options attribute in the easyui tag. Because for backend developers, writing js code may be more familiar than writing html tags, and this makes the html code more concise.

<script>
$(function(){
/*
* 初始化layout
*/
$("#home-layout").layout({
//使layout自适应容器
fit: true
});
/*
* 获取左侧菜单树，并为其节点指定单击事件
*/
$("#home-west-tree").tree({
　　　　//加载菜单的数据，必需
url: "${ctx }/pages/home-west-tree.json",
method: "get",
　　　　//是否有层次线
lines: true,
　　　　//菜单打开与关闭是否有动画效果
animate: true,
　　　　//菜单点击事件
onClick: function(node){
if(node.attributes && node.attributes.url){
　　　　　　　　　//打开内容区的tab，代码在其后
addTab({
url: "${ctx }/" + node.attributes.url,
title: node.text
});
}
}
});
　　/*
* 初始化内容区的tabs
*/
$("#home-tabs").tabs({
fit : true,
　　　　//tab页是否有边框
border : false
});})
</script>
<script>
/*
* 在内容区添加一个tab
*/
function addTab(params){
var t = $("#home-tabs");
var url = params.url;
var opts = {
title: params.title,
closable: true,
href: url,
fit: true,
border: false
};
//如果被选中的节点对应的tab已经存在，则选中该tab并刷新内容
//否则打开一个新的tab
if(t.tabs("exists", opts.title)){
var tab = t.tabs("select", opts.title).tabs("getSelected");
t.tabs("update", {
tab: tab,
options: opts
});
}else{
t.tabs("add", opts);
}
}
</script>

4.json format required by easyui-tree component

The transmission format used by easyui is json, which has strict restrictions on the format of json content, so please pay attention to check the api

[{
"text":"区域管理",
"attributes":{
"url":"pages/consume/area/areaList.jsp"
}
},{
"text":"预约信息管理",
"children":[{
"text":"商户预约信息查询",
"attributes":{
"url":"/pages/consume/reservation/merchantReservation/merchantReservationList.jsp"
}
}]
},{
"text":"准入申请管理",
"children":[{
"text":"商户准入申请",
"state":"closed",
"children":[{
"text":"商户待处理申请",
"attributes":{
"url":"waterAply.do&#63;method=toList&channelType=1&handleFlag=aply_wait"
}
},{
"text":"商户审批中申请",
"attributes":{
"url":"waterAply.do&#63;method=toList&channelType=1&handleFlag=aply_current"
}
},{
"text":"商户审批通过申请",
"attributes":{
"url":"waterAply.do&#63;method=toList&channelType=1&handleFlag=aply_pass"
}
},{
"text":"商户被拒绝申请",
"attributes":{
"url":"waterAply.do&#63;method=toList&channelType=1&handleFlag=aply_refuse"
}
}]
}]
},{
"text":"准入审批管理",
"children":[{
"text":"商户审批管理",
"state":"closed",
"children":[{
"text":"当前任务",
"children":[{
"text":"商户当前初审任务",
"attributes":{
"url":"pages/consume/approval/merchantApproval/merchantApprovalTrial.jsp"
}
},{
"text":"商户当前复审任务",
"attributes":{
"url":"pages/consume/approval/merchantApproval/merchantApprovalRetrial.jsp"
}
}]
},{
"text":"商户已完成任务",
"attributes":{
"url":"pages/consume/approval/merchantApproval/merchantApprovalDone.jsp"
