Proper Date Validation

// validation for Date
function validDate(formField,fieldLabel,required) {
var result = true;
if (required && !validRequired(formField,fieldLabel))
result = false;

if (result) {
if (formField.value){
var elems = formField.value.split("/");

result = (elems.length == 3); // should be three components

if (result) {
//var day = parseInt(elems[0]);
var day = elems[0];
var month = elems[1];
var year = parseInt(elems[2]);

result = allDigits(elems[0]) && (month > 0) && (month < 13) &&
allDigits(elems[1]) && (day > 0) && (day < 32) &&
allDigits(elems[2]) && ((elems[2].length == 2) '' (elems[2].length == 4));
}
}

if (!result) {
alert('Please enter a date in the format DD/MM/YYYY for the "' + fieldLabel +'" field.');
formField.focus();
}
}
return result;
}
