使用原生集成的控件 barcode 调试时在PC端无法调试 需要build 或者云打包到真机上才可以调试
功能常见 点击扫描按钮,然后在此页面的基础上创建扫描页面并开始扫描
扫描控件 我是放在dialog(vant2)弹窗中的
此方法在点击扫描按钮后,会有一秒中的黑屏,各种百度和GPT搜,可能是创建扫描控件和初始化摄像头不及时造成,并且此方法在连续扫描时,极容易卡死在黑屏页面,此方法不推荐实际开发使用。仅做踩坑记录。
解决办法,在扫描控件创建好之前选择一个页面也代替黑屏,就是做个动画盖住黑屏,
- <template>
- <!--1.首先,弹窗页面中要有el-dialog组件即弹窗组件,我们把弹窗中的内容放在el-dialog组件中-->
- <!--2.设置:visible.sync属性,动态绑定一个布尔值,通过这个属性来控制弹窗是否弹出-->

- :visible.sync="detailVisible"
