详解layuiAdmin单页版根据后台json数据动态生成左侧菜单栏
layuiAdmin单页版根据后台json数据动态生成左侧菜单栏
使用模板方式加载菜单
lay-url=“菜单接口”
lay-headers=“将token带入请求头”，如果没有，去掉就行
在模板中使用console.log 示例： {{# console.log(1) }}
layui.data(‘layuiAdmin’).token 调用本地存储的token,token名需要和本地存储对应
json字段名不需要和这里的一样，json字段名改变，模板里面也要相应的修改
<div class="layui-side layui-side-menu"> <div class="layui-side-scroll"> <script type="text/html" template lay-url="https://easy-mock.com/mock/5c131015dada7b27ac3a5c36/titi/treemenu" lay-headers="{'x-auth-token': layui.data('layuiAdmin').token}" lay-done="layui.element.render('nav', 'layadmin-system-side-menu');" id="TPL_layout"> <ul class="layui-nav layui-nav-tree" lay-shrink="all" id="LAY-system-side-menu" lay-filter="layadmin-system-side-menu"> {{# var path = layui.router().path ,dataName = layui.setter.response.dataName; layui.each(d[dataName], function(index, item){ var hasChildren = typeof item.list === 'object' && item.list.length > 0 ,classSelected = function(){ if(index == 0){ return hasChildren ? 'layui-nav-itemed' : 'layui-this'; } return ''; } ,url = typeof item.href === 'string' ? item.href : item.name; }} <li data-name="{{ item.name || '' }}" data-jump="{{ item.href || '' }}" class="layui-nav-item {{ classSelected() }}"> <a href="javascript:;" {{ hasChildren ? '' : 'lay-href="'+ url +'"' }} lay-tips="{{ item.title }}" lay-direction="2"> <i class="layui-icon {{ item.icon }}"></i> <cite>{{ item.title }}</cite> </a> {{# if(hasChildren){ }} <dl class="layui-nav-child"> {{# layui.each(item.list, function(index2, item2){ var hasChildren2 = typeof item2.list == 'object' && item2.list.length > 0 ,classSelected2 = function(){ if(index==0){ return hasChildren2 ? 'layui-nav-itemed' : 'layui-this'; } return ''; } ,url2 = typeof item2.href === 'string' ? item2.href : [item.name, item2.name, ''].join('/'); }} <dd data-name="{{ item2.name || '' }}" data-jump="{{ item2.href || '' }}" {{ classSelected2() ? ('class="'+ classSelected2() +'"') : '' }}> <a href="javascript:;" {{ hasChildren2 ? '' : 'lay-href="'+ url2 +'"' }}>{{ item2.title }}</a> {{# if(hasChildren2){ }} <dl class="layui-nav-child"> {{# layui.each(item2.list, function(index3, item3){ var match = path[0] == item.name && path[1] == item2.name && path[2] == item3.name ,url3 = typeof item3.href === 'string' ? item3.href : [item.name, item2.name, item3.name].join('/') }} <dd data-name="{{ item3.name || '' }}" data-jump="{{ item3.href || '' }}" {{ match ? 'class="layui-this"' : '' }}> <a href="javascript:;" lay-href="{{ url3 }}">{{ item3.title }}</a> </dd> {{# }); }} </dl> {{# } }} </dd> {{# }); }} </dl> {{# } }} </li> {{# }); }} </ul> </script> </div> </div>
