uni-app自定义app端的扫码界面

不负时光不负卿 · 发表于 2019-12-21 17:33:00

记得当时是在西班牙有这样的一个需求，需要自定义扫码页面，还需要加上西班牙文，当时是在一个组件里面找到了这样的一个方法，全文大部分使用的app端的Native里面的方法，记录一下，跑路了项目代码要删库了

效果图大概是这样的

以下是vue页面代码
<template>
<view></view>
</template>
<script>
import { mapState, mapMutations } from 'vuex';
var barcode = null;
export default {
data() {
return {
name: 'PUEDES ENCONTRAR EL QR AQUÍ', //要在扫码界面自定义的内容
flash: false, //是否打开摄像头
type: 'scan-listener'
};
},
onLoad(d) {
var pages = getCurrentPages();
var page = pages[pages.length - 1];
// #ifdef APP-PLUS
plus.navigator.setFullscreen(true); //全屏
var currentWebview = page.$getAppWebview();
this.createBarcode(currentWebview); //创建二维码窗口
this.createView(currentWebview); //创建操作按钮及tips界面
// #endif
},
computed: {
...mapState(['token', 'user', 'powerBank', 'rackData', 'orderNum', 'slotId']),
i18n() {
return this.$t('richScan');
}
},
methods: {
...mapMutations(['tokenStorage', 'powerBankStorage']),
// 扫码成功回调
onmarked(type, result) {
var text = '未知: ';
console.log('内容' + JSON.stringify(result));
switch (type) {
case plus.barcode.QR:
text = 'QR: ';
break;
case plus.barcode.EAN13:
text = 'EAN13: ';
break;
case plus.barcode.EAN8:
text = 'EAN8: ';
break;
}
plus.navigator.setFullscreen(false);
let results = result.match(/WXXH.*/gi) + '';
this.powerBankStorage(results);
console.log(typeof this.powerBank);
uni.redirectTo({
url: '/pages/money/paydeposit'
});
// this.$eventHub.$emit(this.type, {
// result: result
// });
barcode.close();
},
// 创建二维码窗口
