layuiadmin框架，每次刷新整个页面，都会回到首页，现在想保持在当前页面，
layuiAdmin侧边栏菜单刷新保持当前页面，利用缓存来处理，供自己参考如下：

   layui.config({base: '__ROOT__/homeStatic/layuiadmin/' //静态资源所在路径}).extend({index: 'lib/index' //主入口模块}).use('index',function (){var $ = layui.$, admin = layui.admin, form = layui.form, table = layui.tablevar active = {//点击菜单缓存当前页面menuEvent(){// 刷新$('#LAY-system-side-menu li').click(function(){var tabNum = $(this).index();var tabUrl = $(this).find('a').attr('lay-href');var homeTabMenu = {};if(typeof tabUrl=='undefined') {//二级菜单处理，缓存路径及tab的索引$('#LAY-system-side-menu .layui-nav-child').click(function (){let tabUrl = $(this).find('a').attr('lay-href');let tabNum = $(this).index();let homeTabMenu = {};// console.log(tabUrl)// console.log(homeTabNum)// if(typeof tabUrl=='undefined') {//// }homeTabMenu.tabNum = tabNum;homeTabMenu.tabUrl = tabUrl;sessionStorage.setItem("homeTabMenu", JSON.stringify(homeTabMenu));});}else{// console.log(tabUrl)// console.log(homeTabNum)homeTabMenu.tabNum = tabNum;homeTabMenu.tabUrl = tabUrl;sessionStorage.setItem("homeTabMenu",  JSON.stringify(homeTabMenu));}})},//刷新保持页面stopPage(){// // //刷新保持在当前页面var homeTabMenu = sessionStorage.getItem("homeTabMenu");homeTabMenu = JSON.parse(homeTabMenu);// console.log(homeTabMenu)// console.log(homeTabMenu!='' && homeTabMenu.hasOwnProperty('tabUrl'))// // 将之前的URL设置为iframe的srcif (homeTabMenu!=null && homeTabMenu.hasOwnProperty('tabUrl')) {var a = homeTabMenu.tabUrl;$(`#LAY-system-side-menu a[lay-href="${a}"]`).click();$(`#LAY-system-side-menu a[lay-href="${a}"]`).parents('li').addClass('layui-nav-itemed');}},init:function (){this.menuEvent();this.stopPage();}}active.init();});
