Vue press enter to implement the login process

First bind the listener event in mounted

mounted(){
    //绑定事件
     window.addEventListener('keydown',this.keyDown);
  }

Writing a method to listen for events

 methods:{
    keyDown(e){
        //如果是回车则执行登录方法
      if(e.keyCode == 13){
        this.login();
      }
    }
}

Event to be destroyed last

	destroyed(){
        window.removeEventListener('keydown',this.keyDown,false);
  }
