vue后台管理，刷新浏览器或者关闭浏览器弹窗提示

APP.vue中定义方法

beforeunloadHandler(e) {

    //if (this.$route.name !== "login" && !isHomePage && invalid != 0) {
      //  this.beforeUnloadTime = new Date().getTime();
       // e = e || window.event;
        //if (e) {
         // e.returnValue = "关闭提示";
        //}
        //return "关闭提示";
      //}
}

　mounted中监听 beforeunload  事件

window.addEventListener('beforeunload', e => this.beforeunloadHandler(e))

　　

destroyed中卸载事件

window.removeEventListener('beforeunload', e => this.beforeunloadHandler(e))
