// Router原理
//页面路由
window.location.href = 'https://www.baidu.com'
history.back(); //回退
// hash路由
window.location = '#hash'

//h5路由
history.pushState('name','Title','/path')
// 推进一个状态
history.pushState('test','Title','#test')
//替换一个状态
history.replaceState('test','Title','/index/test')
window.onpopstate = function(e){
window.location.href //全路径
window.location.pathname //绝对路径
window.lacation.hash //hash路由
window.lacation.search
