小程序webview 如何使用wx-open-launch-weapp?
<div class="home">测试按钮
<wx-open-launch-weapp
id="launch-btn"
username="gh_579f93fee087"
@launch="handleLaunchFn"
@error="handleErrorFn"
>
<script type="text/wxtag-template">
<style>.wx-btn { width: 200px; height: 40px; text-align: center; line-height: 40px; font-size: 16px; border-radius: 20px; background: #62c655; color:#fff; border: 0;}</style>
<button class="wx-btn">跳转小程序</button>
</script>
</wx-open-launch-weapp>
</div>
在微信网页里打开是可以的,但webview的小程序里按钮不显示是为什么啊
