本文主要是介绍vue做一个锁屏禁止页面前进后退，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
1.在router.beforeEach()路由首首位加上以下代码
/*** 判断锁屏*///登录的时候存的md5加密的密码let oldPasswordld = localStorage.getItem("lockPassword");//锁屏页面的md5加密密码let newlockPassword = localStorage.getItem("newlockPassword");console.log(oldPasswordld,newlockPassword)if (newlockPassword !== oldPasswordld && to.path !== '/screen') {next('/screen')}
2.书写锁屏页面和相关路由
下面代码为screen/index.js 为锁屏的页面 首先进入这个页面 默认执行一次 unlock方法里面的localStorage.setItem(“newlockPassword”, md5(this.userForm.newPw));
把解锁的密码存到本都对象存储里面，这样路由就好做处理。

};
