Vue

一、给button按钮绑定@keyup.enter

<div class="btn">
       <Button  type="primary" @click="handleAddBook" @keyup.enter="handleAddBook">录入</Button>
</div>

 

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()
                }  
            }
}
