Dropdown runs a query to populate checkboxes - ASP

Hello,

I have an ASP form that has a dynamic dropdown list.  I need the user's selection in the list to populate the form's checkboxes as either being checked or unchecked.

Ie.  In the admin maintenance section the admin will select from a drop down list values such as Admin, Marketing, Accounting, Finance, Sales, etc... the selection will populate checkboxes that represent their access levels, such as Full Access, Limited Access, etc..

The problem with the code that I have now is that it won't allow for a selection.  It keeps submitting the first item and won't allow the user to select any other items.

<select name="Role" onClick="onChangeRole()">
<%
dim oneRole
dim nRoleId
      
sSQL = "SELECT * FROM Role"
set oRs = Server.CreateObject("ADODB.Recordset")
oRs.Open sSQL, oConn,3,3

if not ors.EOF then  ' check to see if recordset empty

oRs.MoveFirst

Do while not oRs.EOF

oneRole = ors.Fields("role")
if strRoleSelected = oneRole then
nRoleId = ors.Fields("roleID")
Response.Write "<option selected  value='" & strRoleSelected & "'>" & strRoleSelected
else
Response.Write "<option  value='" & oneRole & "'>" & oneRole
end if

ors.MoveNext
loop

end if

oRs.Close
oConn.Close

%>
</option>
</select>



<SCRIPT LANGUAGE="JavaScript">
<!--
function onChangeRole()
{
      var GuiList = eval("document.forms[0].Role");
      var strRole = GuiList.value;
      document.forms[0].action = "ChangeRoles.asp?Role=" + strRole;
      document.forms[0].submit();
      
}
function onClickSave()
{
      document.forms[1].submit();
}

// -->

</SCRIPT>

Hi,

  Not exactly certain what you want, but....

1) you should probably be using the onchange event handler, not the onclick event handler.  As soon as the user tries displaying the drop down, s/he is clicking -- so the selected option (if any) will be submitted.

<select name="Role" onchange="onChangeRole()">

2) if you want more than one option to be selected, you need to make the select element 'multiple' :

<select name="Role" multiple onchange="onChangeRole()">


3) Also, you probably should send the form object and the selected option's value to the function so that if the form moves from position '0' to position 'x', it doesn't crash and require a rewrite:

<select name="Role"  onchange="onChangeRole(this.form, this.options[this.selectedIndex].value)">

function onChangeRole(formObj, strRole)
{
    formObj.action = "ChangeRoles.asp?Role=" + strRole;
    formObj.submit();
     
}
