点击到iframe中的链接 [英] click to a link in iframe

问题描述
我正在寻找一种方法来单击VBA代码中iframe中的链接
i search for a method to click to a link in an iframe in VBA code
我仍然做了什么：
Set IEApp = GetObject("new:{D5E8041D-920F-45e9-B8FB-B1DEB82C6E5E}")
IEApp.Visible = True
IEApp.navigate "https://meineseite.../LoginForm.jsp" 'anpassen
Start = Now
Do: Loop Until IEApp.Busy = False
Do: Loop Until IEApp.Busy = False
Do: Loop Until IEApp.Document.ReadyState = "complete"
Do
'On Error Resume Next
If DateDiff("s", Start, Now) > 0 Then Exit Do
Loop Until IEApp.ReadyState <> 4
Set IEDocument = IEApp.Document
IEDocument.all.USER.Value = "Benutzer"
IEDocument.all.PASS.Value = "Passwort"
IEDocument.getElementsByName("LoginForm")(0).submit
工作完美。因此，现在有一个字段用于输入名称，然后打开一个包含2个或更多链接的框架。所以我必须搜索正确的。
完成了...但是如何单击这些链接之一？
work perfectly. so now there is a field to give a Name in, and then it's open a frame with 2 to or more links. so i have to search the right. its done... but how can i click on one of these links?
我尝试了以下操作：
Call IEDocument.frames(1).execScript("choose('Objektnummer, Referenznummer')", "JavaScript")
IEDocument.parentWindow.frames.Navigate "choose('Objektnummer, Referenznummer')"
IEDocument.parentWindow.Links(2).Click
也许我是这样写的：
IE.Document.getElementById("?").contentDocument.getElementById("?").Click
，但是我在中输入了什么？ ？
but what have i put into "?" ?
所以这是iframe代码：
so here is the iframe code:
DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
</head>
<script type="text/javascript">
function choose(wert) {
top.document.getElementById("links").value=wert;
parent.absenden("LINKS");
top.document.getElementById("IFRAME").style.visibility = "hidden";
}
function close(){
top.document.getElementById("IFRAME").style.visibility = "hidden";
}
</script>
<body bgcolor="white">
<span style="font-family:sans-serif; font-size:12px;">
<table style="font-size:12px;font-weight:none;" width="100%" border="0" cellspacing="0" cellpadding="0">
<tr>
<td colspan="2" align="right">
<a href="JavaScript:close();" style="text-decoration:none;color:#000000;font-weight:bolder;">X </a>
</td>
</tr>
<tr> <td colspan='2' nowrap="nowrap"> <a href="javascript:choose('nichtgewaehlt')">Bitte wählen</a> </td> </tr>
<tr> <td colspan='2' nowrap="nowrap"> <a href="javascript:choose('Objektnummer, Referenznummer')">Objektname</a> </td> </tr>
<tr> <td colspan='2' nowrap="nowrap"> <a href="javascript:choose('Objektnummer2, Referenznummer2')">Objektname2</a> </td> </tr>
</table>
</span>
</body>

推荐答案
尝试使用CSS选择器将iframe中的元素定位为目标。
Try using a CSS selector to target the element within the iframe.
如果您认为这是计时问题，则可以
If you think it is a timing problem you can
1）循环，而目标元素为空，即未设置；超时以避免潜在的无限循环
1) loop while target element is nothing i.e. not set; with timeout to avoid potential for infinite loop
Dim t As Date, ele As Object, waitTime As Long
t = Timer
waitTime = 10 '<== secs
Do
DoEvents
On Error Resume Next
Set ele = IEDocument.frames("IFRAME").document.querySelector("a[href=javascript:choose('Objektnummer, Referenznummer')]")
On Error GoTo 0
If Timer - t = waitTime Then Exit Do '<==To avoid infinite loop
Loop While ele Is Nothing
Call IEDocument.iframe.execScript("Choose('Objektnummer,Referenznummer')", "JavaScript")
2）设置一个明确的等待时间
2) Set an explicit wait
Application.Wait Now + TimeSerial(0,0,5) '<== adjust 5 which is number of seconds
Call IEDocument.iframe.execScript("Choose('Objektnummer,Referenznummer')", "JavaScript")
