小编改写了一个扫码二维码功能,这个虽然网络上的案例有很多,基本上都是扫一下后就弹出提示框,提示框里就是二维码的链接,小编改成扫描二维码后对应相对的网站,包含了内部浏览器,为什么要弄个内部浏览器呢?因为mui跳转网站内容的话那APP就会自动关闭掉,所以需要弄个内部浏览器用于浏览外链网站的。
如何实现呢?添加三个文件(点击进入扫码 -> 扫码 ->扫码后的结果)
- index.html:是首页,需要写个点击事件进入扫码页(小编就不写这个页面了)
- Ewm.html:是扫码页
- target.html:是扫码后的结果页面
Ewm页面
<!doctype html>

self.append(baiduWV);
});
</script>
</body>
</html>
效果:
扫码页面(有闪光灯功能)
扫码后
别忘记引入mui自带的css和js喔!!!
