I have a simple classic asp that uses a web service which returns a url that I need to display. I'm having problems displaying the returned string. I can not figure out the correct syntax to do this. Here is the code:

<html>
<head>
<title>Calling a webservice from classic ASP</title>
</head>
<body>
<%
If Request.ServerVariables("REQUEST_METHOD") = "POST" Then
Dim xmlhttp
Dim chartUrl
Dim DataToSend
DataToSend="acctNum="&Request.Form("txtacctNum")&"&MRN="&Request.Form("txtMRN")
Dim postUrl
postUrl = " http://localhost/edChartLink2/edChartLink2/edChartLink.asmx/GetToken"
Set xmlhttp = server.Createobject("MSXML2.XMLHTTP")
xmlhttp.Open "POST",postUrl,false
xmlhttp.setRequestHeader "Content-Type:", "application/x-www-form-urlencoded"
xmlhttp.send DataToSend & "
"
Response.Write(xmlhttp.responseText)
//chartUrl = xmlhttp.responseText

document.write=xmlhttp.responseText

End If
%>
<FORM method=POST name="form1">
Enter the two Values to be Added

<INPUT type="text" name="txtacctNum">
<INPUT type="text" name="txtMRN">



<INPUT type="submit" >
</form>
</body>

I get the url back in xmlhttp.reponsetext with no problem but I have tried using document.write windows.write in various formats and I still get an error.

Error Type:
Microsoft VBScript runtime (0x800A01A8)
Object required: ''
/edChartlink2/edChartlink2/Allscript2.asp, line 21

Can anybody shed some light on this and tell me what is the correct syntax.

Note: I'm new at this, thanks
Jose'

Solution 1

document object does not exist in VB. It's a javascript thingie and even in Javascript, document.write is a method and not a property. Should be used like

document.write("whatever...")

Comment from OP:
So how would I call the url from my code?

Thanks

Manas,
The OP is executing javascript on the server side of classic code. I don't think this will work. There is no document object for server side javascript code. He needs the Response object to write to the output stream.

Never mind, early monday morning, need to finish my cup of tea first. I thought he was using javascript, on second look he is using vbscript.

Solution 3

The other responder has already explained the cause of the issue.

Just replace the line:

VB

document.write=xmlhttp.responseText

with

VB

document.write(xmlhttp.responseText)

and it should work fine.

As Yusuf pointed out that document is a DOM object and couldn't be processed at server side.

You are already writing the value of xmlhttp.responseText to the Response, what the next line is for?
Commenting that line should work fine.

~~This does not seem right solution, see my comment in Manas's answer.~~

:)BTW, in Classic ASP any scripting language including JavaScript can be used.

Yusuf 23-Feb-11 8:52am

I know javascript can be used. Can you call the document DOM from the server side? like document.write

Ankur^\m/ 23-Feb-11 9:09am

Oh I see what you mean. AFAIK, you are correct. 'Document' is DOM object and must be present inside the script tag. How could a DOM object be processed on the server?!
I haven't tried it though.

Anyways I will edit my answer.
Thanks a lot! :)

But it seems the solution worked for OP because he accepted the answer and haven't left any comment.

Hi I ended up using Response.Redirect xmlhttp.reponseText. But that is giving me problems in which I open up separate thread.

Thanks for your help

Ankur^\m/ 25-Feb-11 8:22am

I will check it out.

Thanks for informing. :)
