Question

我在尝试从网站中提取 href 时遇到困难。我已经坚持了几天了。如下图所示，我可以获得所有其他必需的信息。我已经为该类尝试了多种变体，并尝试通过 a 标签获取它，但是我无法解决。

这是我最近的尝试，仍然无法解决

问题，有人可以指出正确的班级吗？

        If element.getElementsByClassName("product-card ")(0).getElementsByClassName("listing-fpa-link")(0) Is Nothing Then
            wsSheet.Cells(sht.Cells(sht.Rows.Count, "A").End(xlUp).Row + 1, "A").Value = "-"
        Else
            HtmlText = element.getElementsByClassName("product-card")(0).getElementsByClassName("listing-fpa-link")(0).href
            wsSheet.Cells(sht.Cells(sht.Rows.Count, "A").End(xlUp).Row + 1, "A").Value = HtmlText
        End If

结果

一如既往地提前致谢。

Answer 1

好的，我已经解决了这个问题。我将父类更改为 Set elements = HTML.getElementsByClassName("search-page__result")

然后把我的代码改成

   If element.getElementsByClassName("js-click-handler listing-fpa-link tracking-standard-link")(0) Is Nothing Then
            wsSheet.Cells(sht.Cells(sht.Rows.Count, "A").End(xlUp).Row + 1, "A").Value = "-"
        Else
            HtmlText = element.getElementsByClassName("js-click-handler listing-fpa-link tracking-standard-link")(0).href
            wsSheet.Cells(sht.Cells(sht.Rows.Count, "A").End(xlUp).Row + 1, "A").Value = HtmlText
        End If

结果

难以从网站抓取产品 href
