请问，怎么把多个二维码的内容展示在文本框？

scan: function(e) {
var that = this;
uni.scanCode({
onlyFromCamera: true,
success: function(res) {
console.log(JSON.stringify(res)); //{"result":"http://www.baidu.com","scanType":"QR_CODE","charSet":"utf8","path":"","errMsg":"scanCode:ok"}
console.log('条码类型：' + res.scanType); //条码类型
console.log('条码内容：' + res.result); //条码内容
that.result = res.result;
console.log(that.result)
},

                fail: function(res) {  
                    uni.showToast({  
                        icon: 'none',  
                        title: '请重新扫码'  
                    })  

                }  
            });  
        },
