 <html>
<head>
<meta charset="utf-8">
<title>Simple Registration Form</title>
<script type="text/javascript">
    function checkName(form)              /* for real name verification */
    {
        var oRE = /^[a-z0-9]+[_.-]?[a-z0-9]+$/i;
       var isCorrectFormat = oRE.test(text);
       if (!isCorrectFormat)
        {
          alert("Invalid characters in username. It can only contain...");
          return false;
        }             


 if (form.realname.value == '')
        {
            alert('Error: Username cannot be blank!');
            form.realname.focus();
            return false;
        }
        
        return true;
    }
    
    function checkEmail(form) /* for email validation */
    {
        if (/^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*(\.\w{2,3})+$/.test(form.email.value))
        {
            return true;
        }
        
        alert('Invalid E-mail Address! Please re-enter.');
        return false;
    }
    
    function validatePwd(form) /* password & retype-password verification */
    {
        var invalid = ' ', minLength = 6;
        var pw1 = form.password.value, pw2 = form.password2.value;
 
        if (pw1 == '' || pw2 == '')
        {
            alert('Please enter your password twice.');
            return false;
        }
 
        if (form.password.value.length < minLength)
        {
            alert('Your password must be at least ' + minLength + ' characters long. Try again.');
            return false;
        }
 
        if (document.form.password.value.indexOf(invalid) > -1)
        {
            alert('Sorry, spaces are not allowed.');
            return false;
        }
        else
        {
            if (pw1 != pw2)
            {
                alert('You did not enter the same new password twice. Please re-enter your password.');
                return false;
            }
            else
            {
                alert('Successfull.');
                return true;
            }
        }
    }
    
    function validPhone(form) /* phone no validation */
    {
        var valid = '0123456789', phone = form.phoneno.value;
        
        if (phone == '')
        {
            alert('This field is required. Please enter phone number');
            return false;
        }
        
        if (!phone.length > 1 || phone.length < 10)
        {
            alert('Invalid phone number length! Please try again.');
            return false;
        }
        
        for (var i = 0; i < phone.length; i++)
        {
            temp = '' + phone.substring(i, i + 1);
            
            if (valid.indexOf(temp) == -1)
            {
                alert('Invalid characters in your phone. Please try again.');
                return false;
            }
        }
        
        return true;
    }
    
    function validate()
    {
        var form = document.forms['form'];
        
        if (!checkName(form) || !checkEmail(form) || !validatePwd(form) || !validPhone(form))
        {
            return false;
        }
