LayUI之动态树

思路

静态页面数据是什么样？
分析需要什么样的数据？
我们如何得到这些数据？
将现有的数据如何转换成我们需要的数据？
将具有层级关系的数据渲染成树形结构.

main.jsp

<div class="layui-side layui-bg-black">
    <div class="layui-side-scroll">
      <!-- 左侧导航区域（可配合layui已有的垂直导航） -->
      <ul class="layui-nav layui-nav-tree" lay-filter="test" id="layui_menus">
        <li class="layui-nav-item layui-nav-itemed">
          <a class="" href="javascript:;">menu group 1</a>
          <dl class="layui-nav-child">
            <dd><a href="javascript:;" onclick="openTab('','','')">menu 1</a></dd>
            <dd><a href="javascript:;">menu 2</a></dd>
            <dd><a href="javascript:;">menu 3</a></dd>
            <dd><a href="">the links</a></dd>
          </dl>
        </li>
        <li class="layui-nav-item">
          <a href="javascript:;">menu group 2</a>
          <dl class="layui-nav-child">
            <dd><a href="javascript:;">list 1</a></dd>
            <dd><a href="javascript:;">list 2</a></dd>
            <dd><a href="">超链接</a></dd>
          </dl>
        </li>
        <li class="layui-nav-item"><a href="javascript:;">click menu item</a></li>
        <li class="layui-nav-item"><a href="">the links</a></li>
      </ul>
    </div>
  </div>

此处后台代码...

main.js

let layer,$,element;
layui.use(['jquery', 'layer', 'element'], function(){
	layer = layui.layer
	,$ = layui.jquery
	,element = layui.element;
	$.ajax({
		url:'${pageContext.request.contextPath }/permission.action?methodName=menus'
		,dataType:'json'
		,success:function(data){
			let htmlstr = '';
			let json = data.data;
			$.each(json,function(i,n){
				htmlstr += '<li class="layui-nav-item layui-nav-itemed">';
				htmlstr += ' <a class="" href="javascript:;">'+json[i].text+'</a>';
				if(json[i].hasChildren){
					let children = json[i].children;
					$.each(children,function(index,node){
						htmlstr += '<dl class="layui-nav-child">';
						htmlstr += '<dd><a href="javascript:;" onclick="openTab(\''+children[index].text+'\',\''+children[index].attributes.self.url+'\',\''+children[index].id+'\');" >'+children[index].text+'</a></dd>';

				htmlstr += '</li>';

			$("#layui_menus").html(htmlstr);

LayUI之动态选项卡

思路

选项卡简介
动态添加选项卡
重复选项卡的限定
切换指定选项卡
选项卡样式
用户登录-结果返回R类的增强

1.选项卡

<style>
	.layui-tab-title>li:first-child>i{
		display:none;
	}
	.layui-tab>.layui-tab-content{
		padding:0px;
	}
	body,html{
		padding:0px;
		margin:0px;
		overflow:hidden;
	}
</style>

main.jsp

<div class="layui-body">
    <!-- 内容主体区域 -->
    <div style="padding: 15px;">
    	<div class="layui-tab" lay-filter="openTab" lay-allowclose="true">
		  <ul class="layui-tab-title">
		    <li class="layui-this" lay-id="-1">首页</li>
		  </ul>
		  <div class="layui-tab-content">
		    <div class="layui-tab-item layui-show">首页内容</div>
		  </div>
		</div>
    </div>

main.js

function openTab(title,url,id){
	let $node = $("li[lay-id='"+id+"']");
	if($node.length == 0){
		element.tabAdd('openTab', {
	      title: title
	      ,content: "<iframe frameborder='0' src='"+url+"' scrolling='auto' style='width:100%;height:100%;'></iframe>"

LayUI之用户管理

思路

用户查询
用户角色case when后台处理
用户新增
用户修改
用户删除

1.用户查询

2.case when的处理

	}

				"(case rid\r\n" + 
				"when 1 then '管理人员'\r\n" + 
				"when 4 then '参与者'\r\n" +
