Re: Javascript Validation Coldfusion ?
Hi
I have just tried all your suggestions shown below and it is still not working?
The javascript validation kicks in for the two input fields and displays Title of the
Uploaded File
but the two select boxes did not activate the validation messages?
Any ideas why?, I have attached the code snippet below that I am using.
---
SCRIPT LANGUAGE=JavaScript
!-- Begin
function checkFields() {
missinginfo = ;
if (document.form.dltitle.value == ) {
missinginfo += \n - Title of the File Uploaded;
}
if (document.form.dlsummary.value == ) {
missinginfo += \n - Descriptive Summary of Uploaded File;
}
if(document.form.area.value == 1){
missinginfo += \n - Please select option for Sel1;
}
if(document.form.dlos.value == 1){
missinginfo += \n - Please select option for Sel2;
}
if (missinginfo != ) {
missinginfo =

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

Re: Javascript Validation Coldfusion ?
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
script
function validateSelect(){
if (document.form.fieldname[selectedIndex].value == ){
alert(Please select an option in the select box.);
return false;
}
}
/script
onsubmit=return validateSelect()
This assumes that you have an option in the select box with an empty
value...
option value=(select option)

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?

if (document.form.filesummary.value == ) {
missinginfo += \n - Descriptive Summary of Uploaded File;

Re: Javascript Validation Coldfusion ?
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. - Original Message - From: [EMAIL PROTECTED] To: CF-Talk [EMAIL PROTECTED] Sent: Thursday, August 16, 2001 6:40 AM Subject: RE: Javascript Validation Coldfusion ?

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:
select name=sel1
option value=1 SELECTEDChoose option for this select/option
option value=2Option2 Sel 2/option
/select
select name=sel2
option value=1 SELECTEDChoose option for this select/option
option value=2Option 2 Sel2/option
/select
I do not know what you are asking as far as your CFFILE question though.

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. JoAnn A.

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.

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
