General - Question - Get value of SelectedIndex

How do I get the value of a SelectedIndex?

See below code

<script>
function toggleTextBox(){

var x = document.myform.hotOrderList.options;

if(x.[this.selectedIndex].value == 'Yes'){

document.myform.txtHotOrderName.style.display = '';
}
else{
document.myform.txtHotOrderName.style.display = 'none';
}
}
</script>

Regards,
Edmond

This is not ASP, this is JavaScript.

this would work:

Code:

if (document.myform.hotOrderList.value == 'Yes') {

if(document.myform.refreshList.options[document.myform.refreshList.options.selectedIndex].value == 'No'){
document.myform.refreshnum.style.display = '';
document.myform.refreshnote.style.display = '';
}
else{
document.myform.refreshnum.style.display = 'none';
document.myform.refreshnote.style.display = 'none';

in order for this to work, you must have form named "myform" and this
form should have drop down element named "refreshList", case sensitive.
if you don't have any of those you will, indeed, get error.

Ah crap, sorry, I edited your post rather than posting a new one.

Can you respost your code, including the <option> tags?

Sorry dude!

hey.. it's ok
here is the code - see below

the dropdown list is reading from db
it doesn't have to be..

Code:

<body onload="toggle();">

<form name="myform">

<script>
function toggle(){
	var s = document.myform.refreshList;
	
	if(s.options[s.selectedIndex].value  == 'No'){
	document.myform.refreshnum.style.display = '';
		document.myform.refreshnote.style.display = '';
	}
	else{ 
	document.myform.refreshnum.style.display = 'none';
		document.myform.refreshnote.style.display = 'none';
	}
}
</script>

<select size="1" name="refreshList" onChange="toggle();" tabindex="3">
<option selected></option>
	
<%  
If refreshList <> "" Then
   Response.Write "<option selected>" & refreshList & "</option>"
End If
	
sql = "Select refresh From refresh Order By id"
set conn = Server.CreateObject("ADODB.Connection")
conn.open "provider=sqloledb;data Source=server;initial catalog=dashboard;integrated security=SSPI;"            
set rs = conn.execute(sql)
	            
do while not rs.eof
thisfield = trim(rs(0))
      	if isnull(thisfield) or thisfield="" then
	'                 
      	else
    		response.write "<option>" & thisfield & "</option>"
       	end if
             rs.movenext
loop
	%>		
</select>

you get error because your form does not contain element
named "refreshnum". add such element and try again.
