it just takes some getting used to:
1. write the JS function
<script...>
function checkForm(theForm){
var selInd = theForm.state.selectedIndex;
var boxVal = theForm.state.options[selInd].value;
if( boxVal != "" )
return true;
alert("You must select a state");
return false;
}
2. Put ONSUBMIT in the form tag
<form.... onsubmit="return checkForm(this);">

Subject: Silly Validation Question...
Hey,
Does anyone have a good script or method of making a select box contain a
value other than ""?
I am working on a state drop-down in which the first selection is "Pick
State" with a value of "".
What I want to happen is for a javascript screen to pop up (or something
like that--you know the usual CFFORM javascript validation) if a user tries
to submit the form without choosing a state that has a value. I have seenm
this used many times and even with CFSELECT form fields, but I am having the
worst time trying to implement this.
I want to populate the CFSELECT with a query from a State_Table but do not
want to store a state with a value of "" as not to populate a state field
with NULL answer.
Is there an OnError or someother Javanscript function that could make sure
that a value other than "" was chosen and that the error message could be
configurable. I know that this is so CF 101, but I have never had to do
this and am pulling my hair out in anger.
Thanks a ton,
BW
