How do I select item in <SELECT>

[K. Lobe]

list box based on a POST method to the same page.

frm.cmbList.Value=Request.Form("cmbList") doesn't work.

When the page loads, it reloads the <SELECT>, so not sure how to get the
list to go to the item.

Any ideas?

many thnx,

Assuming you've got a window_onload event:
frm.cmbList.Value="<%=Request.Form("cmbList")%>"

At the end of the page... you want to make sure this doesn't execute until
after the <select> has loaded.

Something like this... see a JavaScript newsgroup for better syntax and
examples (the only ASP-related part here is getting the ASP variable into
client-side script).

<script>
var selected = 0;
for (i=0; i<document.frm.cmbList.options.length; i++)
{
if (document.frm.cmbList.options.value ==
"<%=request.form("cmbList")%>")
{
selected = i;
i = document.frm.cmbList.options.length;
}
}
document.frm.cmbList.selectedIndex = selected;
</script>

You could also consider building the select list in ASP, e.g.

<%
dim options(3)
options(0) = "foo"
options(1) = "bar"
options(2) = "fu"
options(3) = "barred"
response.write "<select>"
for i = 0 to 3
response.write "<option value='" & options(i) & "'"
if options(i) = request.form("cmbList") then
response.write " selected"
end if
response.write ">" & options(i)
next
response.write "</select>"
%>
