Hi everyone, first off I would just like to say that javascript it not my thing so please bear with me. I am using the below script to validate my form, at the moment the script changes the class of the input if it is not valid, but I would quite like it to also change the class of a input after it has been validated. Below is the script:


var Validate = new Class({

getOptions: function(){
return {
validateOnBlur: true,
errorClass: 'error',
errorMsgClass: 'errorMessage',
dateFormat: 'dd/MM/yy',
onFail: Class.empty,
onSuccess: false,
showErrorsInline: true,
label: 'Please wait...'
};
},

initialize: function(form, options){
this.setOptions(this.getOptions(), options);

this.form = $(form);
this.elements = this.form.getElements('.required');

this.list = [];

this.elements.each(function(el,i){
if(this.options.validateOnBlur){
el.addEvent('blur', this.validate.bind(this, el));
}
}.bind(this));

this.form.addEvent('submit', function(e){
var event = new Event(e);
var doSubmit = true;
this.elements.each(function(el,i){
if(! this.validate(el)){
event.stop();
doSubmit = false
this.list.include(el);
}else{
this.list.remove(el);
}
}.bind(this));

if(doSubmit){
if(this.options.onSuccess){
event.stop();
this.options.onSuccess(this.form);
}else{
this.form.getElement('input[type=submit]').setProperty('value',this.options.label);
}
}else{
this.options.onFail(this.getList());
}

}.bind(this));

},

getList: function(){
var list = new Element('ul');
this.list.each(function(el,i){
if(el.title != ''){
var li = new Element('li').injectInside(list);
new Element('label').setProperty('for', el.id).setText(el.title).injectInside(li);
}
});
return list;
},

validate: function(el){
var valid = true;
this.clearMsg(el);

switch(el.type){
case 'text':
case 'textarea':
case 'select-one':
if(el.value != ''){
if(el.hasClass('email')){
var regEmail = /^[A-Z0-9._%-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$/;
if(el.value.toUpperCase().match(regEmail)){
valid = true;
}else{
valid = false;
this.setMsg(el, 'Please enter a valid email address');
}
}

if(el.hasClass('security')){
var regSec = /<? echo $sec; ?>/;
if(el.value.match(regSec)){
valid = true;
}else{
valid = false;
this.setMsg(el, 'The securty number does not match the picture');
}
}

if(el.hasClass('number')){
var regNum = /[-+]?[0-9]*\.?[0-9]+/;
if(el.value.match(regNum)){
valid = true;
}else{
valid = false;
this.setMsg(el, 'Please enter a valid number');
}
}

if(el.hasClass('postcode')){
var regPC = /^([Gg][Ii][Rr] 0[Aa]{2})|((([A-Za-z][0-9]{1,2})|(([A-Za-z][A-Ha-hJ-Yj-y][0-9]{1,2})|(([A-Za-z][0-9][A-Za-z])|([A-Za-z][A-Ha-hJ-Yj-y][0-9]?[A-Za-z])))) [0-9][A-Za-z]{2})$/
if(el.value.match(regPC)){
valid = true;
}else{
valid = false;
this.setMsg(el, 'Please enter a valid postcode');
}
}

if(el.hasClass('date')){
var d = Date.parseExact(el.value, this.options.dateFormat);
if(d != null){
valid = true;
}else{
valid = false;
this.setMsg(el, 'Please enter a valid date in the format: '+this.options.dateFormat.toLowerCase());
}
}

}else{
valid = false;
this.setMsg(el);
}
break;

case 'checkbox':
if(!el.checked){
valid = false;
this.setMsg(el);
}else{
valid = true;
}
break;

case 'radio':
var rad = $A(this.form[el.name]);
var ok = false;
rad.each(function(e,i){
if(e.checked){
ok = true;
}
});
if(!ok){
valid = false;
this.setMsg(rad.getLast(), 'Please select an option');
}else{
valid = true;
this.clearMsg(rad.getLast());
}
break;

}
return valid;
},

setMsg: function(el, msg){
if(msg == undefined){
msg = el.title;
}
if(this.options.showErrorsInline){
if(el.error == undefined){
el.error = new Element('span').addClass(this.options.errorMsgClass).setText(msg).injectAfter(el);
}else{
el.error.setText(msg);
}
el.addClass(this.options.errorClass);
}
},

clearMsg: function(el){
el.removeClass(this.options.errorClass);
if(el.error != undefined){
el.error.remove();
el.error = undefined;
}
}

});

Validate.implement(new Options);
Validate.implement(new Events);

And it is started by this code on the page that I am using it on:

window.addEvent('domready', function(){
var myFormValidation = new Validate('contact',{
errorClass: 'red'
});
});

Thanks in advance for any help
