You can't access the ASP variables directly, because ASP is done on the
server, and Javascript is on the client (web browser). By the time the
Javascript is "executing" the ASP has already finished.

You can try this though :-

Items[1]=["First Name", "<%=strFirstNam e%>",""]
Items[2]=["Last Name", "<%=strLastName %>",""]

HTH!

Re: Using ASP Variables

I've done something like the following to get ASP variables into javascript

<%
strFirstName = (whatever you want it to equal)
strLastName = (whatever you want it to equal)

Response.Write "<script language=JavaSc ript>"
Response.Write "var sFirstName=" & strFirstName
Response.Write "var sLastName=" & strLastName
Response.Write "</script>"

Now, the variables sFirstName and sLastName are available to your JavaScript

What you have done, is written a <script> block via ASP that gives you
JavaScript variables....

Re: Using ASP Variables

Bengee:
Thanks for the help. the <%= info didn't help. Do you know if the javascript
code can use it if I create a session object for the variable? I tried some
of this with no luck.

There's no way Javascript can access an ASP variable. However,
Javascript is the "output" from the ASP code, so you can set a
Javascript variable to be that of an ASP variable. Once this is set
though and being viewed in the browser, you can't change it server-side
without some sort of re-sumbit mechanism.

Have a look a Mike's example below.

Bengee:
I'm trying what Mike mentioned since it really makes sense; getting ASP to
generate the javascript code, but it doesn't work for me yet. I have the
response.buffer =True set. Not sure what I'm doing wrong.

Post some code here then and let us have a look.

Re: Using ASP Variables

Here is my exact code. This page receives a URL as the following
"NewPage.asp?TB LS=AttMarket&TB LS=ConfComment"

In ASP, a reference to Request("TBLS") will return the string
"AttMarket,Conf Comment"

I take that info and save it into a JavaScript array that I can access
throughout the page on the client side...
<preliminary HTML stuff>
<body onload="Loaded( )">
<%

'-- A bunch of code that means nothing as far as your question goes...

'-- Throw out some JavaScript make it easy to get to the Request
parameters.
Response.Write "<script Language=" & chr(34) & "JavaScript " & chr(34) & ">"
Response.Write "numTables= " & Request("TBLS") .Count & ";"
Response.Write "allTables = new Array(" & (Request("TBLS" ).Count - 1) &
");"
For i = 1 to Request("TBLS") .Count
Response.Write "allTables[" & (i - 1) & "] = " & chr(34) &
Request("TBLS") (i) & chr(34) & ";"
Next
Response.Write "</script>"

'-- More code that means nothing

%>
</body>

This is the code generated (from View->Source)

<body onload="Loaded( )">
<script Language="JavaS cript">numTable s=2;allTables = new
Array(1);allTab les[0] = "AttMarket";all Tables[1] = "ConfCommen t";</script>
<more html stuff>
</body>

Trivial:

Items[1]=["First Name", "<%= session('FirstN ame') %>",""];
Items[2]=["Last Name", "<%= session('LastNa me') %>",""];

If <%= %> doesn't evaluate properly inside double-quotes (I'm not sure how
ASP deals with this), then you could use something like:

Items[1]=["First Name", <%= dquote(session( "FirstName" )) %>,""];
Items[2]=["Last Name", <%= dquote(session( "LastName") ) %>,""];

(where dquote() is a little function that you provide that wraps the passed
string in double-quotes)

Sorry, I should've replied to Graig L posting.
But my point still stands. You can not use client-side javascript to
read data directly from a database.

Hey Gang:
I'll try what Jeff said to do as soon as I get a chance - probably this
afternoon. Will let you know and post the working code for others.

Re: Using ASP Variables

I think I can get this to a simplier problem now that I have played with it.
Here is what is happening. This code works for what I'm trying to do:

<SCRIPT language=JavaSc ript>

var strFirstName="D on"

var strLastName="Ro se"

</SCRIPT>

<SCRIPT>

Items[0]=[strFirstName, "", ""];

Items[1]=[strLastName, "", ""];

</SCRIPT>

This code getting ASP to write the javascript equivalent like this, doesn't
work:

<%

response.write "<SCRIPT Language=" & chr(34) & "JavaScript " & chr(34)

response.write "var strFirstName=" & chr(34) & "Don" & chr(34)

response.write "var strLastName=" & chr(34) & "Rose" & chr(34)

response.write "</SCRIPT>"

%>

<SCRIPT>

Items[0]=[strFirstName, "", ""];

Items[1]=[strLastName, "", ""];

</SCRIPT>

If I can just get this right, I can get the rest working on my own.
