项目需求:H5项目需要实现扫描二维码或条形码功能。
html5-qrcode使用
1.安装
npm install html5-qrcode --save-dev
2.引入
-
- import { Html5Qrcode } from 'html5-qrcode';
3.定义所需变量
- data: function() {
- return {
- html5QrCode: null,
- isShow: false,
- scanReasonList: []
- };
- },
4.创建容器(可根据需求写样式)
- <div class="reader" v-if="isShow">
- <div id="reader-box"></div>
- </div>
5.实现扫码逻辑
在一个button或者其他节点上绑定事件“scanCode”
- scanCode() {
- this.startScan();
- },
- startScan() {
- this.isShow = true;
- Html5Qrcode.getCameras().then(devices => {
- if (devices && devices.length) {
- this.html5Qrcode = new Html5Qrcode('reader-box');
- this.html5Qrcode.start(
- {
- facingMode: 'environment'
- },
- {
- fps: 10,
- qrbox: { width: 250, height: 250 }
- },
- (decodeText, decodeResult) => {
- if (decodeText) {
- this.scanReasonList.push(decodeText);
- this.stopScan();
- this.isShow = false;
- }
- },
- err => {
- console.log('失败', err);
- }
- );
- }
- });
- },
- stopScan() {
- this.html5Qrcode.stop();
- },

至此,可基本实现扫码功能。具体的参数配置可参考官网 Getting started | ScanApp
