I programmed this to check my form data, however, it does not work. First I check all the values, if they are null, then I check if email adress is valid and then I check if the checkbox is checked.
When I submit the form with no values on input, it successfully loads the document specified in action="#", which should not happen because of the return false;.
function validateForm() {
var meno = document.forms["registracia"]["meno"].value;
var priezvisko = document.forms["registracia"]["priezvisko"].value;
var telefon = document.forms["registracia"]["telefon"].value;
var email = document.forms["registracia"]["email"].value;
var vek = document.forms["registracia"]["vek"].value;
var praca = document.forms["registracia"]["praca"].value;
var motto = document.forms["registracia"]["motto"].value;
var osoba = document.forms["registracia"]["osoba"].value;
if (meno == null || meno =="" || priezvisko == null || priezvisko =="" ||
telefon == null || telefon =="" || email == null || email =="" ||
vek == null || vek =="" || praca == null || praca =="" ||
motto == null || motto =="" || osoba == null || osoba =="" ||) {
alert("Musíte vyplniť všetky údaje.");
return false;
}
var re = /^(([^<>()[\]\\.,;:\s#\"]+(\.[^<>()[\]\\.,;:\s#\"]+)*)|(\".+\"))#((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/;
if(!re.test(email)) {
alert("Zadajte platnú e-mailovú adresu.");
return false;
}
if(!document.forms["registracia"]["suhlas"].checked) {
alert("Musíte súhlasiť s uverejnením vašej fotografie.");
return false;
}
}
You had an extra || at the end of your if condition. You can also make it a bit more readable, see below.
function validateForm() {
var form = document.forms["registracia"];
if ( !form.meno.value
|| !form.priezvisko.value
|| !form.telefon.value
|| !form.email.value
|| !form.vek.value
|| !form.praca.value
|| !form.motto.value
|| !form.osoba.value ) {
alert("Musíte vyplniť všetky údaje.");
return false;
}
var re = /^(([^<>()[\]\\.,;:\s#\"]+(\.[^<>()[\]\\.,;:\s#\"]+)*)|(\".+\"))#((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/;
if(!re.test(form.email.value)) {
alert("Zadajte platnú e-mailovú adresu.");
return false;
}
if( !form.suhlas.checked ) {
alert("Musíte súhlasiť s uverejnením vašej fotografie.");
return false;
}
}

I currently have a working function that checks if all of the forms fields are not blank. For part of a form, i have a hidden div that will appear if one of the fields has an answer of yes selected in the drop down. when i have the drop down item selected as yes, i would like for the function to check if any one of those fields are left empty, and when the drop down has an answer of no, i don't want the function to check the values of the hidden div items. i can't seem to figure out a way to accomplish this. this is what i have tried so far. the variable label2 contains the value of the drop down menu, Yes/No.

I have a sign up form on my page at http://business.uglyopportunities.com/affiliate-signup/ (scroll down to see the form)
Keep in mind, I am not very good with JS so this may be a simple error.
Anyways, here is the first line of my form telling it to validate:
<form accept-charset="UTF-8" action="xxxxx" class="infusion-form" method="POST" name="myform" onsubmit="return validateForm();">
and here is my validateForm javascript:
<script type="text/javascript">
function validateForm() {
var a = document.forms["myform"]["inf_field_FirstName"].value;
var b = document.forms["myform"]["inf_field_Email"].value;
var c = document.forms["myform"]["inf_field_Phone1"].value;
var d = document.forms["myform"][" inf_field_StreetAddress1"].value;
var e = document.forms["myform"][" inf_field_City"].value;
var f = document.forms["myform"][" inf_field_State"].value;
var g = document.forms["myform"][" inf_field_PostalCode"].value;
var h = document.forms["myform"][" inf_other_Username"].value;
var i = document.forms["myform"][" inf_other_Password"].value;
var j = document.forms["myform"][" inf_other_RetypePassword"].value;
if (a == null || a == "" || a == "First Name Here") {
alert("Please enter your First Name!");
return false;
}
if (c == null || c == '' || c == "Enter Your Phone Here" || c.length < 9) {
alert("Please insert your phone number!");
return false;
}
if (d == null || d == '' || d == "Street Address”) {
alert("Please insert your street address ");
return false;
}
if (e == null || e == '' ||e == "City”) {
alert("Please insert your city");
return false;
}
if (f == null || f == '' || f == "State”) {
alert("Please insert your state ");
return false;
}
if (g == null || g == '' ||g == "Postal Code”) {
alert("Please insert your postal code");
return false;
}
if (h == null || h == '' || h == "Username”) {
alert("Please insert your username ");
return false;
}
if (i == null || i == '' ||i == "password”) {
alert("Please insert your password");
return false;
}
if (j == null || j == '' || j == "password”) {
alert("Please re - type your password ! ");
return false;
}
var emailRegEx = /^[A-Z0-9._%+-]+#[A-Z0-9.-]+\.[A-Z]{2,4}$/i;
if (document.myform.inf_field_Email.value.search(emailRegEx) == -1) {
alert("Please enter a valid email address.");
return false;
}
}
</script>
and that is not working. However, when I used this code, it worked fine:
<script type="text/javascript">
function validateForm() {
var a=document.forms["myform"]["inf_field_FirstName"].value;
var b=document.forms["myform"]["inf_field_Email"].value;
var c=document.forms["myform"]["inf_field_Phone1"].value;
if (a==null || a=="" || a=="First Name Here") {
alert("Please enter your First Name!");
return false;
}
if (c==null || c==''|| c=="Enter Your Phone Here" || c.length < 9) {
alert("Please insert your phone number!");
return false;
}
var emailRegEx = /^[A-Z0-9._%+-]+#[A-Z0-9.-]+\.[A-Z]{2,4}$/i;
if (document.myform.inf_field_Email.value.search(emailRegEx) == -1) {
alert("Please enter a valid email address.");
return false;
}
}
</script>

You have a white space here:
var d = document.forms["myform"][" inf_field_StreetAddress1"].value;
// ^-----------------------
You have the same problem with for e,f,g,h,i,j
Also, you used the wrong quotes sign:
"Street Address”
// ^--------------
You did it several times.
As gdoron says, it's probably an spelling problem. You cannot begin the name of an element with a whitespace http://www.w3.org/TR/html401/types.html#type-name
onsubmit="check_rfields();" in form tag of html. But getting failed in validation.
function check_rfields() {
var name = document.getElementById("id_rname").value;
var email = document.getElementById("id_remail").value;
var cemail = document.getElementById("id_rcemail").value;
var password = document.getElementById("id_rpassword").value;
var cpassword = document.getElementById("id_rcpassword").value;
if(name=='' || name==0
&& email=='' || email==0
&& cemail=='' || cemail ==0
&& password=='' || password==0
&& cpassword=='' || cpassword==0 ) {
document.getElementById("onsubmitErr").innerHTML
= "All fields arerequired";
return false;
}
return true;
}
If you want the submit to fail (on failed validation), use:
onSubmit="return check_rfields()"
Problem:
I have a web page. When I fill in the data and hit save, it gives me a a confirmation pop up box. On cancel I want to refresh the page. So the data entered is cleared.
Here is the code for confirmation so far:

if ((anum.test(x)) && (anum.test(y)) && (anum.test(z)) && (anum.test(a)) && (anum.test(b)) && (anum.test(c)))
testresult = confirm('save change?');
else {
