javascript - 通过VBA提取隐藏在页面源代码中的javascript表

Question

我想从由 javascript 创建的页面中提取表格，但它的元素未显示在页面源代码中。这是页面 ( Link )。

在 Firefox 中，我可以通过“查看选择源”找到源的隐藏部分。但 VBA 无法访问隐藏元素:

    <div class="dataTables_wrapper no-footer" id="arzeshdarayi_wrapper"><div class="dt-buttons"><a href="#" aria-controls="arzeshdarayi" tabindex="0" class="dt-button buttons-copy buttons-html5"><span>Copy</span></a><a href="#" aria-controls="arzeshdarayi" tabindex="0" class="dt-button buttons-excel buttons-html5"><span>Excel</span></a><a href="#" aria-controls="arzeshdarayi" tabindex="0" class="dt-button buttons-print"><span>Print</span></a></div><div class="dataTables_filter" id="arzeshdarayi_filter"><label><input aria-controls="arzeshdarayi" placeholder="جستجو" class="" type="search"></label></div><table style="width: 100%;" aria-describedby="arzeshdarayi_info" role="grid" id="arzeshdarayi" class="display dataTable no-footer" cellspacing="0" width="100%">

Answer 1

试试这个。它应该为您获取所需的表格数据:

Sub TableData()
    Dim IE As New InternetExplorer, html As HTMLDocument
    Dim post As Object, elem As Object, trow As Object

    With IE
        .Visible = False
        .navigate "http://www.iafi.ir/%DA%AF%D8%B2%D8%A7%D8%B1%D8%B4%D8%A7%D8%AA/%D8%A7%D8%B1%D8%B2%D8%B4-%D8%AF%D8%A7%D8%B1%D8%A7%DB%8C%DB%8C-%D9%87%D8%A7-%D9%88-%D8%AA%D8%B9%D8%AF%D8%A7%D8%AF-%D9%88%D8%A7%D8%AD%D8%AF-%D9%87%D8%A7"
        While .readyState < 4: DoEvents: Wend
        Set html = .document
    End With

    Application.Wait Now + TimeValue("00:00:05") 'this is the trick here to get the data

    Set post = html.getElementById("arzeshdarayi")

    For Each elem In post.Rows
        For Each trow In elem.Cells
            c = c + 1: Cells(r + 1, c) = trow.innerText
        Next trow
        c = 0
        r = r + 1
    Next elem
    IE.Quit
End Sub
