uniapp 生成二维码插件:https://ext.dcloud.net.cn/plugin?id=3870
公司的二维码链接有加密,原先的uniapp是生成二维码的插件,扫码反应太慢,故在网上搜索,整理此插件。
<template> <view> <view style="margin-top: 26upx;margin: 40upx;"> <ayQrcode ref="qrcode" :modal="modal_qr" :url="url" @hideQrcode="hideQrcode" /> </view> </view> </template> <script> import ayQrcode from "@/components/ay-qrcode/ay-qrcode.vue" export default { components: { ayQrcode, }, data() { return { //二维码相关参数 modal_qr: false, url: ‘https://pixabay.com/images/search/?order=ec‘, // 要生成的二维码值 } }, onLoad() { let that = this; that.showQrcode();//一加载生成二维码 }, methods: { // 展示二维码 showQrcode() { let _this = this; this.modal_qr = true; // uni.showLoading() setTimeout(function() { // uni.hideLoading() _this.$refs.qrcode.couponQrCode() }, 50) }, //传入组件的方法 hideQrcode() { this.modal_qr = false; }, } } </script> <style lang="scss"> </style>
