'document' is undefined?

Hello,

I'm getting the following error with a JavaScript function I'm using:

----------------------------------------------------------

Microsoft JScript runtime error '800a1391'
'document' is undefined
pe/verify.asp, line 24

----------------------------------------------------------

The following function is the one that's causing the error and is on line 24. Frankly, I have no idea why the error's appearing. I thought the document object was automatically included in JavaScript? Here's the function:

----------------------------------------------------------

<SCRIPT LANGUAGE="JScript" runat=server>

function SendInfo()
{
document.frmMain.submit();
}

</SCRIPT>

----------------------------------------------------------

Note that this is being used along with VBScript in an ASP page, so it's already determined with VBScript whether the form should be submitted or not. This is a predefined, read-only, hidden form that is used only to send information between pages. I'm open to any suggestions, I'm on a deadline with this project.

Thanks in advance.

try replacing document.frmMain.submit(); with document.forms[0].submit();

Why you want the following 'runat=server'. This may be the cause of the problem. 'runat=server' means you want the script to run at the server.

Try this :

<SCRIPT LANGUAGE="JavaScript">

function SendInfo()
{
document.frmMain.submit();
}

</SCRIPT>

Well, I tried nzjonboy's solution, and the same error showed up, unfortunately.

With nimaig's solution, the error mentioned above didn't appear, but it said that the variable SendInfo() was undefined. That's why I need it to run on the server, so that VBScript and ASP (which runs on the server) can access it.

nimaig

I don't think you can access the document object using Server side JavaScript.

Can you be bit more descriptive why you want the SendInfo() to be in Server side.

programming_novice

ASKER

I need SendInfo to be on the Server side because that's the only way VBScript (which is server-side in an ASP page) can access it.

However, if anyone can think of any alternatives, I'd be glad to hear them.

nimaig

Why you want VBScript to access this method. Can you please explain the scenerio.

nzjonboy

>it said that the variable SendInfo()
was undefined

how are you calling the SendInfo function?

if you are calling it along these lines

sendInf = SendInfo()

then perhaps you could try putting a return true; statement after the submit.

nzjonboy

nimaig

If I am not mistaken, you want the form to be submitted as soon as the page gets loaded. If so
you can do something like this.
<HTML>
<HEAD>
<SCRIPT LANGUAGE="JScript" runat=server>

</SCRIPT>
</HEAD>
<body onLoad="SendInfo()">
<form name="frmmain">
</form>
</body>
</head>

If you want conditional submit, you can modify the SendInfo something like this
function SendInfo(){
<% if form has to be submitted { %>
document.frmMain.submit();
<% } %>
}

programming_novice

ASKER

nimaig, I tried your method, but instead of using the VBScript inside the JScript, I just used JScript to carry out the conditional program flow. However, now I always get the error that's supposed to come up when the form isn't supposed to be sent, even if it is. Any ideas?

BTW, I've increased the points to 150.

nimaig

Can you post your code please ...

Try something like this. I don't have server to run server side JavaScript/JScript so I haven't tested the code.

<SCRIPT LANGUAGE="JScript" runat=server>

function Reset()
{
Response.Write("top.location.href = 'default.asp');
}

var strUID = Request.Form("username");
var strPass = Request.Form("password");

var strRita = perRita;
var strRitaPass = perRitaPass;
var strAdmin = perAdmin;
var strAdminPass = perAdminPass;
var submitFlag = true;

switch (strUID)
{
case strRita:
if (strPass = strRitaPass)
{
submitFlag = true;
}
else
{
Response.Write("Error: You have entered an incorrect password. Please go back and try again.");
submitFlag = false;
}

case strAdmin:
if (strPass = strAdminPass)
{
submitFlag = true;
}
else
{
Response.Write("Error: You have entered an incorrect password. Please go back and try again.");
submitFlag = false;
}

default:
Response.Write("Error: You have entered an incorrect user name and/or password. Please go back and try again.");
submitFlag = false;

}

if(submitFlag){
Response.Write("<SCRIPT language='JavaScript'>function SubmitForm(){ document.frmMain.submit(); } </SCRIPT>");
}else{
Response.Write("<SCRIPT language='JavaScript'>function SubmitForm(){ } </SCRIPT>");
}
</SCRIPT>

</HEAD>
<BODY onLoad="SubmitForm()">

OK, sorry to be a bother, but now I get a different error:

"Active Server Pages error 'ASP 0138'

Nested Script Block

/pe/verify.asp, line 31

A script block cannot be placed inside another script block. "

This error is on the "if(submitFlag)" line with writing the script tags inside the Response.Write.

Try this :

<HTML>
<HEAD>

<SCRIPT LANGUAGE="JScript" runat=server>

Response.Write("top.location.href = 'default.asp'");

var strUID = Request.Form("username");

I'm still getting the same error as before:

It says (or my code says) that I've entered an incorrect user name and/or password, even if I've entered correct values?

Also, because this is really important and I'm running on deadline, I've raised the number of points to 200 (it'll leave me with 6 points, but I'm desperate for an answer, so oh well).

I'm still getting my error message about the username being incorrect. BTW, I'm running this on PWS.

nimaig

May I know from where r u getting this value.

var strUID = Request.Form("username");
var strPass = Request.Form("password");

Try with some constant value like

var strUID = "Rita";
var strPass = "whs";

programming_novice

ASKER

This is a verification page for a web database app. strUID is the value of the information sent from the previous log-in page. There are multiple users (only two in this example), which is why I need to know what the value is each time, and not use a constant.

nimaig

I never meant to tell you to use constant. I told u to check if the code works using constant. Anyway, I have rectified the problem u r facing. Try the code below.

Ok, well, now I don't get my error all the time, and if I enter an incorrect username, I get the correct error (thanks). However, as long as it's a valid username, I get logged in, even if I enter an incorrect password. Any suggestions?

Thanks again.
