我们公司使用基于浏览器的程序进行业务运营。我的目标是自动从系统中获取一些数据。
该网站本身使用相当多的帧,但我正在做相当不错的处理。我面前的问题是导航到我的数据所在的屏幕。
链接本身是用javascript编码的,我没有看到锚标记 (图像为+/-,或间距不可见):
源代码
<div id='Nav_4' aTag='aTarget' title='Target' aUrl="javascript:top.aaa.submitPage('NavigateTo','~/aPages/aPage.aspx?UC=a')">
<img alt='' style="margin-left:0px; width:0px "/>
<img src='/a/a.axd?d=a' alt='(Collapsed)' aAltX='(Expanded)' imgType='exp' />
<img alt=''style='width:5px; visibility:hidden;'>
<span atxt='1' class=" breadcrumbTreeItem">
Target
</span></div>
由于我无法获取标签,或者在文档中搜索链接,我试图找到包含“目标”的span标记并尝试激活它。
这是工作代码! (i5是迭代器)
Set ie = GetOpenIEByURL("https://aaa.com/AAA.htm")
fIter = 0
For Each frmSet In ie.document.getElementsByTagName("Frame")
If Left(frmSet.src, 7) = "aaa/AAA" Then
myFrame = f_Iter
Exit For
End If
f_Iter = f_Iter + 1
Next
With ie
For i5 = 0 To ie.document.frames(myFrame).document.all.tags("SPAN").Length - 1
With .document.frames(myFrame).document.all.tags("SPAN").Item(i5)
If InStr(.innerText, "Target") > 0 Then
.Click
Exit For
End If
End With
Next i5
End With
此外,在模块中,添加以下代码:
'Finds an open IE site by checking the URL
Function GetOpenIEByURL(ByVal i_URL As String) As InternetExplorer
Dim objShellWindows As New ShellWindows
'ignore errors when accessing the document property
On Error Resume Next
'loop over all Shell-Windows
For Each GetOpenIEByURL In objShellWindows
'if the document is of type HTMLDocument, it is an IE window
If TypeName(GetOpenIEByURL.document) = "HTMLDocument" Then
'check the URL
If Left(GetOpenIEByURL.document.URL, 30) = Left(i_URL, 30) Then
'leave, we found the right window
Exit Function
End If
End If
Next
End Function
答案 0 :(得分:0)
查看您的代码,我看到了
elementList = ie.document.frames(myFrame).document.getElementsByTagName("span")
哪个应与Set
一起使用,如下所示:
Set elementList = ie.document.frames(myFrame).document.getElementsByTagName("span")
就Dim
行上的错误而言,您始终可以将其定义为Object
或Variant
,这仍应有效,因为{{返回}的类型1}}应该仍然有效。
响应您的更新,点击按钮,我使用:
getElementsByTagName
与你的代码混合,我会像这样(未经测试)把它放在一起:
Set objButton = IEPage.getelementbyid("buttonname")
IEPage.onmousedown 'There is JS code that catches these actions for validation, so we artificially trigger them on the page. Your requirements may vary.
objButton.Focus
objButton.Click
