当我尝试使用变量来指定要使用的类列表中的哪个元素时,我得到“对象不支持此属性或方法”(运行时错误“438”)错误.
For tdNum = 0 To 1000
If document.getElementsByClassName("prod-somm")(tdNum).getElementById("no-piece").innerText = ItemNbr Then
Cells(cell, 2).Value = document.getElementsByClassName("prod-somm")(tdNum).getElementById("col-action").getElementsByTagName("span")(0).innerText
Exit For
End If
Next tdNum
HTML:
<table align="center" cellspacing="0" class="prod-somm">
<tbody>
<tr>
<td align="center" rowspan="2" class="prod-somm-image"></td>
<td class="prod-somm-texte" valign="top">
<a href="/eng/Balance-of-system/Fuse-and-holder/Wohner-31110.000/p/284" id="no-piece">
90-FT017
<span class="prod-somm-sepno"></span>
<span id="panier_fab_284">Wohner</span>
<span id="panier_nomanufact_284">31110.000</span>
</a>
<a href="/eng/Balance-of-system/Fuse-and-holder/Wohner-31110.000/p/284"></a>
</td>
</tr>
<tr>
<td id="col-action">
<div class="prix">
<span id="panier_prix_284">10.43</span>
</div>
</td>
</tr>
</table>
问题发生在if document.getElementsByClassName(“prod-somm”)(tdNum).getElementById(“no-piece”).innerText = ItemNbr Then
目标是使程序在搜索结果列表中运行,直到找到与我的Excel电子表格中的项目编号匹配的项目编号,然后获取与该项目对应的价格.
编辑:
这是整个代码.可能会让我想要做的更清楚一些.

最佳答案 方法getElementById仅在html文档上可用,而不在html元素上.
但是由于你有重复的id,这里你最好的选择可能是使用querySelector获取目标元素.
请注意,标准强制使用唯一ID,但不会在浏览器中强制执行.
这是一个可以帮助您入门的示例:
' execute the query
Dim xhr As New MSXML2.XMLHTTP60
xhr.Open "GET", "https://rematek-energie.com/eng/pg/1/r/5", False
xhr.send
' load the html
Dim html As New HTMLDocument, html2 As Object
Set html2 = html
html2.write xhr.responseText
' scrap the html
Dim elements As MSHTML.IHTMLElementCollection
Dim element As MSHTML.IElementSelector
Dim link As IHTMLElement
Set elements = html.getElementsByClassName("prod-somm")
For i = 0 To elements.Length - 1
Set element = elements(i)
' get the link with id="no-piece"
Set link = element.querySelector("a[id='no-piece']")
If Not link Is Nothing Then
' display the product code
Debug.Print link.FirstChild.data
End If
Next
