VBA 如果使用的范围包含 word/text/value，则返回上一步

Question

我写了一个从网站下载数据的宏，网站完全加载后，它会通过html标签抓取数据，但有时由于未知错误导致数据抓取错误，我想在每个变体 'x' 完成后添加一个检查，例如如果activesheet中包含“中报”字样，则返回“'Select报表类型”步骤重新抓取。另外，我知道一些 variables/data 类型不是一开始就设置的。谁能帮忙解决这个问题？提前致谢！

这已经清理了很多。

我添加了一个 SelectReportType: 行标签。每当您想返回到该条件时，请使用插入行

Goto SelectReportType

它会带你到那个地方。更好的方法是将该代码放在一个单独的函数中，这样您就可以在“中报”测试为真时随时调用它。但我没有很好地遵循你的代码，无法理解你正在做什么来帮助你。

VBA 如果使用的范围包含 word/text/value，则返回上一步

VBA If used range contains a word/text/value, go back to previous step

vba

if-statement

goto

redo

contain
