安拆

npm install html5-qrcode

代码

<template>
	<view class="container">
		<button class="scan" @click="scanCode">掀开相机扫码</button>
		<view class="reader-box" v-if="isScaning">
			<view class="reader" id="reader"></view>

	</view>
</template>
<script>
	import {
		Html5Qrcode
	} from 'html5-qrcode';
	export default {
		data() {
			return {

				isScaning: false,
			}
		},
		methods: {
			startScan() {
				this.isScaning = true;

测试成果

uniapp运转到涉猎器

到此那篇闭于uniapp正在h5页里完成扫码罪能(html5-qrcode)的文章便引见到那了,更多相闭html5 qrcode扫码形式请搜刮剧本之野之前的文章或者持续涉猎上面的相闭文章,心愿巨匠之后多多支撑剧本之野!
