Is there any Problem in the below JavaScript Form Validation Code
function validation() {
var uName = document.querySelector('#user').value;
var email = document.querySelector('#mail').value;
var pas = document.querySelector('#pass').value;
var cPas = document.querySelector('#cPass').value;
var ucheck = /^[a-zA-Z0-9]{3,15}$/;
var cmail = /^[a-zA-Z0-9_.-]{3,}@[A-Za-z0-9]{2,6}[.]{1}[a-zA-Z.]{2,9}$/;
var cpas = /(?=.*[A-Z])(?=.*[0-9])(?=.*[!@#$%^&*])[A-Z]{1}[a-z0-9!@#$%^&*]{5,20}$/
if (ucheck.test(uName)) {
document.querySelector('#uError').innerHTML = "";
} else {
document.querySelector('#uError').innerHTML = "Please Enter Corrent User Name";
return false;
}
if (cmail.test(email)) {
document.querySelector('#mError').innerHTML = "";
} else {
document.querySelector('#mError').innerHTML = "Please Enter Your Email Address";
return false;
}
if (upas.test(pas)) {
document.querySelector('#pError').innerHTML = "";
} else {
document.querySelector('#pError').innerHTML = "Password Length 5-20 Camel Case Alpha Num with Special Char";
return false;
}
