Hi,
I have a novices question. I have a list box control which when selected hunts through a client side array and if it finds a match ( its supposed to ) write contents of the array element to the SAME page.
the only way I have been able to do this so far is with a textarea. Is there a way to write the contents of the client array element below mt control, document.write appears to create a new page.
So I have initially
Company A
Company B
Company C
Company D
If someone clicks on "Company A" then details of Company A are listed below the listbox control
Thanks in advance.

If you are using ASP,
then u can write the code like this.
The following code should be of before the HTML Code
<%
Response.write("<SCRIPT language=javascript>")
'To Create New Array
Response.Write("var state=new Array();")
'Function Starting
Response.Write("function f1(){")
'Creating Default for State
Response.Write("form1.selState.options[0]=new Option('- - Select a State - -',-1);")
dim i,loc,cn,rs,j
set cn=server.CreateObject("adodb.connection")
set rs=server.CreateObject("adodb.recordset")
cn.open "Provider=SQLOLEDB.1;Password=studies;Persist Security Info=True;User ID=studies;Initial Catalog=studies;Data Source=cgvak84"
set rs=cn.Execute("Select * from cgvak_edport_location order by loc_loc_icode")
i=-1
j=1
loc=0
Response.Write("state[" & i+1 & "]=new Array();")
while not rs.EOF
if clng(loc)<> clng(rs.Fields("loc_loc_icode")) then
j=0
i=i+1
loc=rs.Fields("loc_loc_icode")
'To Create a Two Dimensional Array
Response.Write("state[" & i & "]=new Array();")
'To Store the Country Icode in the 0th Element [0][0]
Response.Write("state[" & i & "][" & j & "]='" & rs.Fields("loc_loc_icode") & "';") j=j+1
'To Store the State Icode and Name
Response.Write("state[" & i & "][" & j & "]='" & rs.Fields("loc_icode") & "|" & rs.Fields("loc_name") & "';")
j=j+1
else
response.Write("state[" & i & "][" & j & "]='" & rs.Fields("loc_icode") & "|" &
rs.Fields ("loc_name") & "';")
j=j+1
end if
rs.MoveNext
wend
rs.close
set rs=nothing
%>
}
</script>
<script language=javascript >
function selCountry_onchange()
{
var i,len,len1,hidval
if (form1.selCountry.value==-1)
{
toRemove();
form1.selState.options[0]=new Option('- - Select a State - -',-1);
return;
}
len=state.length;
for (i=0;i<len;i++)
{
if (state[i][0]==form1.selCountry.options[form1.selCountry.selectedIndex].value)
{
toRemove();
for (j=0;j<state[i].length;j++)
{
if (j==0)
{
form1.selState.options[0]=new Option('- - Select a State - -',-1);
}
else
{
sp=state[i][j].split("|");
form1.selState.options[j]=new Option(sp[1],sp[0]);
}
}
}
}
}
function toRemove()
{
len=form1.selState.length;
for(k=0;k<=len;k++)
{
form1.selState.remove(0);
}
}
//-->
</SCRIPT>
<html>
<body onload=f1()>
</body>
</html>

No, sorry I should have explained in more detail, I don't want another trip to the server. I have already populated an array on the client to avoid another trip.

I think you can do it with layers but I'm not over-familiar with writing to layers and it's awkard making it cross-browser compatable.
One thing I did was to have all the javascript in a page in a hidden frame which then wrote javascript and the current output to the main frame.
This was mind numbing though because the javascipt in the "control" page has being written dynamically using server-side javascript.
This meant I had three "levels" of javascript:
Server-side JavaScript writing client-side JavaScipt to write Client-side JavaScript in another page. AAAARRRGGHHH!
works well though! :)

Yes,
the server side JavaScript for client, this is what I was using in the first instance, populating array on server passing back to client, bit of a nightmare, and looks very dirty, but as you say, works ok.
Thanks Mark.
