iFrame re-directs to an error page
I have a form that posts to an iFrame for processing. The iFrame then posts a form forwards in the parent window 开发者_Go百科to a confirmation.
I have added a session variable in the confirmation to indicate that the process is finished.
If the user clicks the back button the form in the iFrame redirects to an error page, but obviously that displays in the iFrame itself.
How can I make the error page trigger in the parent?
If Session("Complete") = 1 Then
Response.Redirect("default.asp?Re-Entry")
End If
Instead of a Response.Redirect, you should use the following:
Response.Write( "<script language='Javascript'>" + _
"window.parent.document.location.href = " + _
"'default.asp?Re-Entry';" + _
"</script>")
It will send back to the iFrame a portion of JavaScript that will instruct it's parent (the main page) to navigate to the error page.
Here is the complete code of my tests:
<%@ Language="VBScript" %>
<%
If Request("op") = "process" Then
If Session("Processed") = 1 Then
Response.Write( "<script>" + _
"window.parent.document.location.href = " + _
"'error.asp?msg=AlreadyProcessed';" + _
"</script>")
Else
Session("Processed") = 1
Response.Write( "<script>" +
"alert('Hello, " + Request("name") + "!');" + _
"</script>")
End If
Response.End
End If
%>
<html>
<body>
<iframe name="parallel" id="parallel" width="100%" height="50" />
<form method="POST" target="parallel" action="iFrame.asp">
<input type="hidden" name="op" value="process" />
<b>Your Name</b><br/>
<input type="text" name="name" width="250" /><br/>
<button type="submit">Submit!</button>
</form>
</body>
</html>
I hope it helps.

Response.Write("<scr" + "ipt language='Javascript'>" + _
"document.parent.navigate('default.asp?Re-Entry');" + _
"</scr" + "ipt>")
