Question
Creating dynamic pulldown
I use the following code to create a dynamic pulldown list :
<select name="buyerSite" style="width:160px;">
<option selected value="0"><< -- Select One -- >></option>
<cfoutput query="qryGet_Site">
<option value="#qryGet_Site.buyersite#">#qryGet_Site.buyersite#</option>
</cfoutput>
</select>
It seems to work when I make a selection from the pulldown. But I am a little confused about the option selected value = "0" statement. When the form is first displayed, << -- Select One -->> is displayed in the pulldown window. If I decide not to make a selection, is the value "0" being passed ?
In my javascriptt edit, I have if (formName.buyerSite.selectedIndex.value == "0".....alert(messese)...etc.,
but nothing is displayed and the form processes.
I tried "0" and 0 and the javascript does not work. What am I doing wrong ? I just need to validate if a pulldown option was selected or not.
Thanks
