RE: Javascript Validation & Coldfusion ?
Can you show me what your form looks like? I have a suspicion that your problem may lie there. In order for my code to work, you have to make sure that at least one of your options for your select is equal to one and that it is a value that you do not want them to be using. Also, on my demo, I went ahead and gave my form a name, such as TestForm and then called it specifically in my code such as document.TestDemo.[selectfeildname].value Hope this helps Larry Juncker Cold Fusion developer -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Friday, August 17, 2001 3:56 AM To: CF-Talk Subject: Re: Javascript Validation & Coldfusion ?

Re: Javascript Validation & Coldfusion ?
hi,
Just a improvement i suggest as this command works in netscape as well as
in IE.
if
(document.form.select_fld_name[document.form.select_fld_name.options.selectedIndex].value
== "0")
The mentioned one
if (document.form.fieldname[selectedIndex].value == ""){
may not work in netscape.
thanks
regards
Sanjeevi

First I recommend you send a blank email to
[EMAIL PROTECTED] and join JS-Jive, the javascript list.
You'll get lots of help with Javascript.
But to answer your question, you need to access the selectedIndex property
of a select box to validate it
function validateSelect(){
if (document.form.fieldname[selectedIndex].value == ""){
alert("Please select an option in the select box.");
return false;
}
}
onsubmit="return validateSelect()"
This assumes that you have an option in the select box with an empty
value...

I have added validation (shown below in the js) for the two text input
fields but need to build in validation for the two select boxes and also a
CFFile field as these are required fields in the form, any ideas on how to
integrate this into what I have below?

RE: Javascript Validation & Coldfusion ?
I do something similar, but run into problems with page caching.
For instance, if an item was added to the database table the populates the
drop-down, between the time you submitted, and hit the OK button to the
alert box, the new item will not appear in the drop down.
The only way around this that I can see is to force no caching of the form
page. Unfortunately, enforcing no caching introduces some other little
issues (Data Missing messages when hitting the back button).
So, I think we will be moving to JS validation on the submitting page -
which would resolve these issues.
Hope this info helps someone.

I tend to place the js in the action page, assuming the dropdown is in a
form.
This is what I use to force someone to select a value from a prefix field.
alert("Please Select a Prefix");
history.back();

RE: Javascript Validation & Coldfusion ?
You're right. Dummy me. I inherited a site that works like this and when I
needed to validate another field, I just parked it with the others. Not the
best answer.

Why would you put it in the action page. You are requiring an extra trip to
the server if you do that. If you put your validation in the calling page
and trigger it with the onclick event of the submit button you save that
trip.

RE: Javascript Validation & Coldfusion ?
Try the following for your two select fields:
if(document.form.sel1.value == 1){
missinginfo += "\n - Please select option for Sel1";
}
if(document.form.sel2.value == 1){
missinginfo += "\n - Please select option for Sel2";
}
Be sure and set up both Selects as follows for this to work:
Choose option for this select
Option2 Sel 2
Choose option for this select
Option 2 Sel2
I do not know what you are asking as far as your CFFILE question though.

Hi
How do you add validation to drop down form select boxes using Javascript. I
have added validation (shown below in the js) for the two text input fields
but need to build in validation for the two select boxes and also a CFFile
field as these are required fields in the form, any ideas on how to
integrate this into what I have below?
