Form validation question
I'm working on a site where people register and choose their own username. In the registration form I'd like to, onBlur from the username field, immediately check to see if that username is already in use and if so, trigger an alert that returns them to the field. What's the best way to do this? Thanks in advance for any help. Les ~| Want to reach the ColdFusion community with something they want?

Re: Form validation question
The JQuery Validate plugin has a method whereby, aside from any standard checks you put in place (not empty, alphanumeric only, etc), it will make an Ajax request and assign a field it's validation status based upon the Ajax status return. http://bassistance.de/jquery-plugins/jquery-plugin-validation/ Steve Cutter Blades Adobe Certified Professional Advanced Macromedia ColdFusion MX 7 Developer Co-Author of Learning Ext JS http://www.packtpub.com/learning-ext-js/book _ http://blog.cutterscrossing.com On 10/15/2009 2:05 PM, Les Irvin wrote: I'm working on a site where people register and choose their own username.

Tricky Form validation Question (for me at least)
This is probably going to take more javascript than I know how to do, since I suck at javascript... First page of a multi-part form has a drop-down of admin namex to pick from. select name=selectAdmin option value=xoxOther - Enter Information Below!/option cfloop query=AIData option value=#MyData.AdminEmail##MyData.AdminNam1#/option /cfloop /select If you ain't in the list, then you should fill in adminNAME and adminEMAIL text fields below that. I've not quit figured out how to validate this on one page. If Other is picked in the select, then I need validation for adminNAME and adminEMAIL to happen before the form can be submitted. If Other ain't picked, then ignore them... I can check for this on the NEXT page of the form and force them to fill in the blanks there, but I want it to take place all on the first page. ~| Introducing the Fusion Authority Quarterly Update. 80 pages of hard-hitting, up-to-date ColdFusion information by your peers, delivered to your door four times a year. http://www.fusionauthority.com/quarterly Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:256130 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4
RE: Tricky Form validation Question (for me at least)
I assume that when the OTHER is selected, the id is ZERO or xox I
didn't know if that was cryptic or not.
// Check for zero option selection
if ( document.form[ 0 ].elements[ selectAdmin ].value == 0 ){
// Validate on OTHER admin info
} else {
// Validate on select box data

if (
(document.yourFormName.selectAdmin.selectedIndex == 0)
(
(document.yourFormName.theTextFieldName.value == ) ||
(document.yourFormName.theTextFieldEmail.value == )
)
)
{
alert('you did it all wrong!');
return false;
}
this assumes that the 'Other' option will always be the first option
in the select list. if this changes, you can modify the first line of
the 'if' as so:
if (
(document.yourFormName.selectAdmin.options[document.yourFormName.selectAdmin.selectedIndex]
..value== xox)
etc

Actually, 'value' works as long as you give it the value from the form
instead of the index.

Re: Tricky Form validation Question (for me at least)
If you are looking for client side validation, CFFORM/CFINPUT is your
friend. You don't need to know any javascript to use it, CF writes the
Javascript for you. Check the live- or quick-docs for specific usage.
If you are looking to make things a bit more fancy, you could throw an
onChange event on your select list that would have the second fields
disabled unless other was selected. It would be something like
select name=selectAdmin onChange=if (this[this.selectedIndex].value !=
'xox') {document.formname.adminName.disabled = true;
document.formname.adminEMAIL.disabled = true;}
else {document.formname.adminName.disabled = false;
document.formname.adminEMAIL.disabled = false;}
That would give your users the info visually that they didn't need to fill
out the second fields if they are not other.
You would still need to use CFFORM to do validation on the second two fields
in the case of other.

RE: Tricky Form validation Question (for me at least)
Anyone of these should work fine as the first if() in the function I
posted...
if(document.forms[0].selectAdmin.selectedIndex == 0) {}
if(document.forms[0].selectAdmin.options[0].selected) {}
if(document.forms[0].selectAdmin.value == 'xox') {}
They seem to all work well across the board for me.

I've always used the options array as well but recently have been using
value with no problems or complaints.

Subject: Re: Tricky Form validation Question (for me at least)
maybe i'm just old and a creature of habit, but i've always referenced
select elements via the options array. i've seen people access the
value directly (and i know it works in newer browsers)...but when i
cry a little :)
i have looked into it to see if it's valid (standard) or not...i've
asked people that I consider to be JS gurus...and i've never gotten
any answer other than it works.
i know newer browsers will support it, but i still don't know if it's
standard, so I prefer to stick to the old-fashioned way (FWIW).

form
select onchange=alert( this.value );
option value=AONE/option
option value=BTWO/option
option value=CTHREE/option
/select
/form
Works fine for me.

Select elements do not have a value property. Replace value with
selectedIndex (use this capitalization) and the above code should work
fine.

Ben:
As of the 1.5 standard, I don't believe JavaScript (ECMAScript, whatever)
included a value property for form elements. As others have said, I've
always used selectedIndex on the options array to get the selected option,
and then referenced that option's value as in:
var formEle = getElementById('formName');
alert(formEle.options[formEle.selectedIndex].value);
All that said, it could be that either value has simply become a
non-standard property to the form element or, because of newer browser's
implementations of the DOM, it has become a semi-standard property. I
haven't been able to find any standards that suggest its status one way or
the other. I also didn't spend too much time looking 8^).
According to the latest standards I've seen, value is not standard. This
could have changed but, because there are so may other ways to get to it and
none of us seem to know for sure whether or not it has become a new addition
to a standard, I'll stick with the other ways of doing it. But that's
obviously a choice that everyone will have to make on their own.
If anyone decides to do some more testing on this, I'd be interested in
knowing if the form element's value is read/write or read only. I would
suspect that it's read only but it would be interesting to find out what
happens if you try to write to the property.

RE: Tricky Form validation Question (for me at least)
As of the 1.5 standard, I don't believe JavaScript (ECMAScript, whatever) included a value property for form elements. Well, strictly speaking, this isn't a JavaScript thing as much as an HTML DOM thing. It's up to the DOM to specify what's what in the browser. In the case of SELECT fields: http://www.w3schools.com/htmldom/dom_obj_select.asp According to this, the VALUE attribute is available for SELECT, and is writeable. I've never tried to do this, though. I still refer to the values of options through the options array, because originally that was the only thing that would work in both Netscape and IE. If anyone decides to do some more testing on this, I'd be interested in knowing if the form element's value is read/write or read only. I would suspect that it's read only but it would be interesting to find out what happens if you try to write to the property. If the above URL is correct, it's writeable. Again, though, if I want to change an option's value, I just delete and recreate the option using the Option constructor.

CF 5 Form validation Question
Argh - trying to dev a CF 5 app on box running MX 7 - and I can't always remember what won't work in CF 5! OK - form validation... cfinput id=firstName name=firstName type=text required=Yes message=You must enter your first name maxLength=25 / According to CF 5 docs, I don't see a darned thing wrong with that. It runs fine locally too. When I put it out on the testing server (CF version unknown, but probably 6 or something...), the above is IGNORED completely and the form submits... If I do a view-source for the page containing the form, the proper javascript seems to have been generated for the page. Any idea what might be causing this? ~| Message: http://www.houseoffusion.com/lists.cfm/link=i:4:229643 Archives: http://www.houseoffusion.com/cf_lists/threads.cfm/4 Subscription: http://www.houseoffusion.com/lists.cfm/link=s:4 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4 Donations Support: http://www.houseoffusion.com/tiny.cfm/54
Form Validation Question
This is sort of confusion to explain, but I will try. I'm attempting to validate a form using the example in MASTERING COLD FUSION 4, pg 390, ex 15.4. Of course the book example is ultra simple. 3 easy text fields, submits to another script that validates by checking to see if value is zero. This is Cold Fusion validation by the way, no Java Script. I would have used, client side JavaScript but could not get CFSELECT to give the popup using the simple message attribute. I know there are other ways w/JavaScript but I'm deep into this way and I think I am close. So, submit the form and then the next script checks for zero values. If a zero value is found, a "you messed up" message is generated and the form field is re-presented to be fixed. All works well, except I'm using a few textareas. If the textareas do not get filled out on the "fix it page" and submitted, they are not giving an error since there is some value in there. !--- Check if an address has been provided --- CFIF Len(Form.Address) is 0 CFSET Valid = False CFSET Error = Error "An Address is required.BR" CFSET address = " textarea name=""Address"" rows=""3"" VALUE=""#Form.Address#"" /textarea" /CFIF But, with another Formfield, !--- Check if a last name has been provided --- CFIF Len(Form.lastName) is 0 CFSET Valid = False CFSET Error = Error "A last Name is required.BR" CFSET lastName = "INPUT TYPE=TEXT NAME=""lastName"" SIZE=30 MAXLENGTH=50 VALUE=""#Form.lastName#""" /CFIF the above can be submited over and over and will trigger the zero value.

Maybe I'm missing the point of your question, but if I do understand what you're saying correctly, then I think the cause of your problem may be as simple as correcting the way you're nesting the double quotes in your code. -Original Message- From: Patricia Lee [mailto:[EMAIL PROTECTED]] Sent: Friday, December 08, 2000 11:55 AM To: CF-Talk Subject: RE: Form Validation Question use len(trim(form.lastname)) If the textbox (You did mean textbox, not text area, yes? a text block is a single line field that can only accept 255 charachters, while a textarea is multiline and has no max character restriction) is empty, this combination of functions returns 0 so your cfif could look like this.. cfif len(trim(form.lastname)) !--- Any number, 1 through whatever, will trip this part --- do something cfelse !--- the number 0 trips this part --- don't /cfif The secret is the trim function. it gets rid of all leading and trailing zeros... and will make your function return 0 when it should. -Original Message- From: Jeff Fongemie [mailto:[EMAIL PROTECTED]] Sent: Friday, December 08, 2000 10:04 AM To: CF-Talk Subject: Form Validation Question This is sort of confusion to explain, but I will try. I'm attempting to validate a form using the example in MASTERING COLD FUSION 4, pg 390, ex 15.4. Of course the book example is ultra simple. 3 easy text fields, submits to another script that validates by checking to see if value is zero. This is Cold Fusion validation by the way, no Java Script. I would have used, client side JavaScript but could not get CFSELECT to give the popup using the simple message attribute. I know there are other ways w/JavaScript but I'm deep into this way and I think I am close. So, submit the form and then the next script checks for zero values. If a zero value is found, a "you messed up" message is generated and the form field is re-presented to be fixed. All works well, except I'm using a few textareas. If the textareas do not get filled out on the "fix it page" and submitted, they are not giving an error since there is some value in there. !--- Check if an address has been provided --- CFIF Len(Form.Address) is 0 CFSET Valid = False CFSET Error = Error "An Address is required.BR" CFSET address = " textarea name=""Address"" rows=""3"" VALUE=""#Form.Address#"" /textarea" /CFIF But, with another Formfield, !--- Check if a last name has been provided --- CFIF Len(Form.lastName) is 0 CFSET Valid = False CFSET Error = Error "A last Name is required.BR" CFSET lastName = "INPUT TYPE=TEXT NAME=""lastName"" SIZE=30 MAXLENGTH=50 VALUE=""#Form.lastName#""" /CFIF the above can be submited over and over and will trigger the zero value. What is wrong with my textareas so they make it past my checking for zero values??
