Vant Weapp 版本

1.10.12

描述一下你遇到的问题。

感谢vant-weapp团队提供组件

我的问题:
使用tabs组件,但是tab是通过数据请求,然后数据遍历渲染出来的。小程序统计JS报错Cannot read properties of null (reading \'width\')
查看组件源码发现,猜测可能是tabs组件中在mountd使用requestAnimationFrame执行任务,是否可以将requestAnimationFrame替换为nextTick 。因为渲染tags有可能内部tab还没有遍历渲染完,就不能获取到内部的tab元素

  1. 一个固定静态tab
  2. 其他tab通过数据遍历

我尝试了一下setTimeout去异步获取数据并设置data 但是没有看到控制台有错误信息 可以提供一个小程序代码片段吗?
