How to get desc of items in select list.

hello-

im trying to cycle thru my list box and get both the value and desc of all the options in it. i use client side javascript to select all the items in the list then call

for(var i=i;i<=Request.Form("lstAvailableCats").Count;i++){
Response.Write(Request.Form("lstAvailableCats").Item(i));
}

but im not getting any output. any help would be great.
thanks - js

typographical error.

for(var i=1;i<=Request.Form("lstAvailableCats").Count;i++){
Response.Write(Request.Form("lstAvailableCats").item(i));
}

i can get all the values now but not the desc's

try this.

var strMsg = '';
for (var i = 0; i < document.frmName.selectName.options.length; i++)
{
strMsg += 'text:' + document.frmName.selectName.options[i].text + '\n';
strMsg += 'value:' + document.frmName.selectName.options[i].value + '\n';
}
alert(strMsg);

are you trying to BUILD a drop down from a form element that was posted?

this is kinda trickey. i have two select boxes, avaiable categories and select categories. the first time the page is loaded the available list is filled from a database. i then allow people to move from the available box to the selected box via client side javascript. if the user fails to fill in one of the fields on the page i reload it and fill back in the fields that they filled in. i want to fill back in both select boxes with the correct values. i can't think of a way to do this server side, so i may have to do it client side.

To do it serverside you need to build the select box something like this.

<select name="selectName">
<%
' get your recordset
Do while not rs.EOF
strOut = strOut & "<option value='" & rs("fieldname") & "'"
If Request.Form("selectName") = rs("fieldname") Then
strOut = strOut & " selected>" & rs("fieldname") & "</option>"
Else
strOut = strOut & ">" & rs("fieldname") & "</option>"
End If
rs.MoveNext
Loop
%>
</select>

yea, i ended up doing it client side. it works well, but i like to do as much as possible server side.

msdixon

server side is good, but it's important not to hit the server too many times. it makes pages an annoyance rather than a help... even on an intranet application.

glad it worked for you.

p.s. did it work with netscape? i know they support the document.createElement() method.
