      录入
     

 

二、浏览器url：event.target.baseURI;

created(){
           this.keyupEnter() }, methods:{            keyupEnter(){                document.onkeydown = e =>{                    let body = document.getElementsByTagName('body')[0]                    if (e.keyCode === 13 && e.target.baseURI.match(/inputbook/) && e.target === body) {                        console.log('enter')                        this.handleAddBook()                    }                }            },            handleAddBook(){                if(this.validate()){                    this._printQrcode()                }              }}
