Hi

Im currently try to run this scrippt where by when the user clicks the delete button the function deleteline() function runs which will display the line id on the page. However I cant seem to get the lineid value to be sent to the broswer.

Any ideas?

Andy

Code: 
<SCRIPT id=DebugDirectives runat=server language=javascript>
// Set these to true to enable debugging or tracing

<script language="JavaScript" type="text/javascript">
<!--
SetPageTitle('View Order')

<%
if len(request("recID")) > 0 then
	strRecordid = request("recID")
else
	strRecordid = request("OrderNo")

Use hidden form fields to submit it or response.write out the form field that may exist already.

Don't have time to read all the code. If you be more specific on when and where the ID is a more detailed reply may come about.

question: why are you response.write'ing "all" of your static HTML code out?

I agree....I used to response.write everything that was conditional, but it takes way more time and is more prone to TAG errors. ASP will work around it if you put it as follows:

Code: 
<% IF myVar = True THEN %>
<P> Hello, your value was correct </p>
<% END IF %>

<A href="[URL unfurl="true"]http://www.easycgi.com/shared_hosting/?kbid=4815&img=easycgi_120x60_5.gif">[/URL]

Actually I believe onpnt meant replacing things like:
Code: 
Response.Write "<script language=""JavaScript"" type=""text/javascript"">" & VbCr
Response.Write "<!--// "& VbCr
Response.Write "function ConfirmChoice()"& VbCr
Response.Write "{ "& VbCr
Response.Write "answer = confirm(""Are you sure you want to delete this order?"")"& VbCr
Response.Write "if (answer !=""0"") "& VbCr
Response.Write "{ "& VbCr

Response.Write "window.location = 'showorder.asp?switch=d&OrderID=" & strRecordid & "&recID=" & strRecordid & "'"& VbCr
Response.Write "} "& VbCr
Response.Write "}"& VbCr
Response.Write "//-->"& VbCr
Response.Write "</script>"& VbCr

with something like:
Code: 
%>
<script language="JavaScript" type="text/javascript">
<!--// 
function ConfirmChoice()
{
answer = confirm("Are you sure you want to delete this order?")
if (answer !="0")
{

window.location = 'showorder.asp?switch=d&OrderID=<%=strRecordid%>&recID=<%=strRecordid%>'
}
}
//-->
</script>

(more stuff, more stuff)
%>

Esaping back into HTML to output a single line often isn't as efficient as just Response.Writing it. Escaping out to write many lines is generally more efficient than Response.Writing each one, especially when you have a concatenation on each line (concatenation is costly).

I'm fairly certain that was what the benchmarks said when we did them, though I don't think I ever followed up to determine where the break even point was between Response.Writing many times vs escaping to HTML.

There is another big plus with not using Response.Write all over the place - you can read it. The worst part of debugging is when you can't understand what it is doing or supposed to do.

Keep it clean and simple.

Inside your while loop you have this line
Code: 
Response.Write "<Input Type=Button onclick=DeleteLine(); return false; value=""Delete"" id=Button1 name=Button1></TD></TR>"
which will be translated to this
Code: 
<Input Type=Button onclick=DeleteLine(); return false; value="Delete" id=Button1 name=Button1></TD></TR>
Can you see what is wrong with this?

Why don't you send the id to the Javascript function like this?
Code: 
%>
<Input Type=Button onclick='DeleteLine(<%=objRs("id")%>);' value="Delete" id=Button1 name=Button1></TD></TR>
<%
Then change your DeleteLine() function to accept a parameter like this (I am following Tarwin's lead and getting rid of the Response.Write):
Code: 
<script language="JavaScript" type="text/javascript">
<!--// 
function DeleteLine(id)
{
  answer = confirm("Are you sure you want to delete this line?")
  if (answer)
  {
    window.location = 'showorder.asp?switch=dl&OrderID=" +id+ "&recID=" +id+ "&lID=" +id+ "'"
  } 
}
//-->
</script>
Although I don't know what the difference is between OrderID, recID, and lID. That is for you to figure out.

Hope this helps.

Quick fix:
Code: 
window.location = 'showorder.asp?switch=dl&OrderID=[COLOR=red]'[/color] +id+ [COLOR=red]'[/color]&recID=[COLOR=red]'[/color] +id+ [COLOR=red]'[/color]&lID=[COLOR=red]'[/color] +id

Thanks for all your ideas.

I used the
Code: 
%>
<Input Type=Button onclick='DeleteLine(<%=objRs("id")%>);' value="Delete" id=Button1 name=Button1></TD></TR>
<%

method however the function at the top doesnt seem to pick up the id. Do I need to pass this through the browser when it refreshes ie. a hidden text box?

Did you modify your javascript like that last code box from Einstein displayed? Your existing javascript function wasn't expecting an argument or using it, so you needed to modify it to acceptthat argument. Your already doing an address change in your function, it's just a matter of giving it the right id to pass in the querystring.
