Help with Form Validator

[argrafic]

i have the following validator:

 

function formValidator(){
// Make quick references to our fields
var nom = document.getElementById('nombre');
var pes = document.getElementById('peso');
var eda = document.getElementById('edad');
var sex = document.getElementById('sexo');
var hrt = document.getElementById('TOTAL');

// Check each input in the order that it appears in the form!
if(isAlphanumeric(nom, "Nombre es requerido.")){
	if(isNumeric(pes, "Peso es requerido y debe ser un número.")){
		if(isNumeric(eda, "Edad es requerido y debe ser un número.")){
			if(madeSelection(sex, "Sexo es requerido.")){
				if(validate_required(hrt, "El total de horas debe de sumar 24.")) {
						return true;
				}
			}
		}
	}
}


return false;

}

function isEmpty(elem, helperMsg){
if(elem.value.length == 0){
	alert(helperMsg);
	elem.focus(); // set the focus to this input
	return true;
}
return false;
}

function isNumeric(elem, helperMsg){
var numericExpression = /^[0-9]+$/;
if(elem.value.match(numericExpression)){
	return true;
}else{
	alert(helperMsg);
	elem.focus();
	return false;
}
}

function isAlphabet(elem, helperMsg){
var alphaExp = /^[a-zA-Z]+$/;
if(elem.value.match(alphaExp)){
	return true;
}else{
	alert(helperMsg);
	elem.focus();
	return false;
}
}

function isAlphanumeric(elem, helperMsg){
var alphaExp = /^[0-9a-zA-Z]+$/;
if(elem.value.match(alphaExp)){
	return true;
}else{
	alert(helperMsg);
	elem.focus();
	return false;
}
}

function lengthRestriction(elem, min, max){
var uInput = elem.value;
if(uInput.length >= min && uInput.length <= max){
	return true;
}else{
	alert("Please enter between " +min+ " and " +max+ " characters");
	elem.focus();
	return false;
}
}

function madeSelection(elem, helperMsg){
if(elem.value == "Please Choose"){
	alert(helperMsg);
	elem.focus();
	return false;
}else{
	return true;
}
}

function emailValidator(elem, helperMsg){
var emailExp = /^[\w\-\.\+]+\@[a-zA-Z0-9\.\-]+\.[a-zA-z0-9]{2,4}$/;
if(elem.value.match(emailExp)){
	return true;
}else{
	alert(helperMsg);
	elem.focus();
	return false;
}
}

function validate_required(field,alerttxt){
with (field)
{
	if (value != 24) {
		alert(alerttxt);
		return false;
	} else {
			return true
			}
}
}

 

i have an issue with the isAlphanumeric validation form, because when people enter a name with spaces it says that it sends teh message that the name fieldname is empty and should be filled.

 

how can i correct it so that it "reads" spaces?

 

thanks!

create a function (untested):

 

function replaceStuff(str){
     if(str.match(/^[a-zA-Z]+$/){
          if(str.match(/ /)){
               return true;
          }
          return true;
     }else{
          return false;
     }
}

Or

function replaceStuff(str){
     return ( str.match(/^[a-zA-Z]+$/) && str.match(/ /) );
}

thanks for the help guys...

 

but i found the solution... and it was pretty simple

 

function isEmpty(elem, helperMsg){
if(elem.value.length == 0){
	alert(helperMsg);
	elem.focus(); // set the focus to this input
	return true;
}
return false;
}

 

that part (in the same code) helped me validate what i wanted...
