LiveValidation only for an option of a select

Hi,
I have a form where a select has some options: only for one options I would validate a field.
on my html file I have:
SELECT -> name="tipo_nolavorazioni"
OPTION -> 80 (from select name="tipo_nolavorazioni")
FIELD -> name="base"

on js file I have assigna variable like here:

var tipo1 = form.elements['tipo_nolavorazioni'].value;

- if TIPO1 = 80 I would validate field BASE < 250;
- if TIPO1 != 80 I would any validation

My problem is that the first time i load page all works good and when I select TIPO1 = 80 live validation works fine.
But when I change TIPO1 to a value different from 80 (TIPO1 != 80) live validation remains and I can't process my form.

I have add a remove function but dosent' works.

Here my code:

window.addEvent('domready', function(){
  var valid = new LiveValidation('text_2', {insertAfterWhatNode : "errore_base"});
  if (tipo1==80) { valid.add(Validate.Numericality, { maximum: 250, tooHighMessage: "Max 250cm" }); };
  if (tipo1!=80)  { valid.remove(Validate.Numericality, { maximum: 250, tooHighMessage: "Max 250cm" }); valid.destroy(); };
  });

here my forms (now I have comment code that validate my forms because I'm on a live site)

Hello monak83,
I'm not a Chrono professional, but after checking your new post, I think that the following links may help:
How can I disable options in a select drop-down?
P.S: I'm just an automated service😉

thanks for your time but your reply is OT!!!
Any ideas?

Hi monak83,

it looks as though your JavaScript only runs when the page is loaded. You presumably need it to run when the option selected changes?

Hi Bob,
thanks so much for your repli.
Can you make an example?

Hi Bob,
I have seen but seems that my live validation is under function onchange and so it should be called every time i change a value in my select.
Where I'm wrong?

Hi Monak,

As Bob already suggested, you need to set your code to run when the select changes, just wrap the 3 lines inside into a select element change event.

$('select').addEvent('change',function(event) {
    //??
});

Hi Max,
I have added this cod at the bottom of my .js file...but dosen't works.
I have added out of my function updatethis(form) called with onchange.
Where i'm wrong?
http://www.sgagrafica.com/stampa-banner-striscioni.html

window.addEvent('domready', function(){
	 $('select_5').addEvent('change',function(event) {
		var valid = new LiveValidation('text_2', {insertAfterWhatNode : "errore_base"});
		if (tipo1==80) { valid.add(Validate.Numericality, { maximum: 250, tooHighMessage: "Max 250cm" }); };
		if (tipo1!=80)  { valid.remove(Validate.Numericality, { maximum: 250, tooHighMessage: "Max 250cm" }); valid.destroy(); };
	 });
	});

I monak83,

It's a few years since ChronoForms used LiveValidation and I'm not longer very familiar with it. The script you posted doesn't seem to have any onChange event?

Bob

Hi Bob,
on my webpage you can see this:

<select class="cf_inputbox" id="select_5" size="1" title="Effettua una scelta!"  name="tipo_nolavorazioni" 
onkeyup="validateNumber()" onclick="validateNumber()" onChange="updatethis(this.form);">

http://www.sgagrafica.com/stampa-banner-striscioni.html

Any help?

The onChange event calls a function named "updatethis", but the code you had should be triggered when any change is done to the field, assuming the page doesn't have any JS errors.

Where do you have your JS code placed ?

You can see on the HEAD tag of my page http://www.sgagrafica.com/stampa-banner-striscioni.html.
IF you would see a more clear view you can found js file called in head tag here: http://www.sgagrafica.com/forms/banner_peso.js

Hi Monak,

I'm not sure, please try again the code I posted, maybe with a new form field, just make sure the field id matches the one in the code, and check if it works, it may need some debugging before you can get it to work!

Max

Chronoforms add some code like FORM tag so I don't know how debgging this. Do you think is a chronoforms bug or a bug on my JS file?
I can't solve this problem...I hope that experts like you will helpe me!!!
Thanks for your time
