I would like to match email address with the confirm email address. I have tried this validation but it's not working. Don't know why.
function ValidationRequired(field, alerttxt){
with (field){
if (value==null || value==""){
alert(alerttxt);
return false;
}else{
return true;
}
}
}
function ValidateThisForm(thisform){
with(thisform){
if(ValidationRequired(EmailAddress, "You must supply an e-Mail address.") == false){
EmailAddress.focus();return false;
}
}
with(thisform){
if(ValidationRequired(EmailAddressConfirm, "You must confirm your e-Mail address.") == false){
EmailAddressConfirm.focus();return false;
}
}
with(thisform){
if(ValidationRequired(EmailAddress != EmailAddressConfirm, "Those emails don\'t match!") == false){
EmailAddressConfirm.focus();return false;
}
}
return true;
}
The first parameter to the function ValidationRequired is supposed to be a field. In the code that is supposed to match the email addresses, the first parameter is not a field, but a boolean expression.
with(thisform){
if(ValidationRequired(EmailAddress != EmailAddressConfirm, "Those emails don\'t match!") == false){
EmailAddressConfirm.focus();return false;
}
}
You could solve this in a few different ways. One way would be to write a second validation function that takes two field parameters and compares the values of two fields.
But if you want to know why the code isn't working, it's because your not passing a field to the function.

I am trying to write a JS function which blocks users from submitting a personal email. Here is the code. When I remove the "alert" line, the user is blocked from a successful form submission. But there is no alert that prompts them to enter a business email.
$("form").submit(function(){
// Get the email value from the input with an id="Email-2"
var email_addr = $('#Email-2').val();
// The regex to check it against
var re = '[a-zA-Z_\\.-]+#((hotmail)|(yahoo)|(gmail))\\.[a-z]{2,4}';
// Check if the email matches
if(email_addr.match(re)){
// Email is on the filter list
// Return false and don't submit the form, or do whatever
window.alert("Enter Business Email");
return false;
} else {
// Email ok
// Allow the form to be submitted
return true;
}});
Below is where there error is occuring. I'm new to Javascript so it very likely could be a syntax issue.
window.alert("Enter Business Email");
return false;
I found a solution that worked, changed the code to the following:
$('#wf-form-Book-Demo-Form').submit(function(){
var email = $('#Email-2').val();
var reg = /^([\w-\.]+#(?!gmail.com)(?!yahoo.com)(?!hotmail.com)(?!yahoo.co.in)(?!aol.com)(?!abc.com)(?!xyz.com)(?!pqr.com)(?!rediffmail.com)(?!live.com)(?!outlook.com)(?!me.com)(?!msn.com)(?!ymail.com)([\w-]+\.)+[\w-]{2,4})?$/;
if (reg.test(email)){
return 0;
}
else{
alert('Please Enter Business Email Address');
return false;
}
});
I would like to know how can i pass a function after form is submitted so that i can pass the input box values to a hidden field. So for an instance if i submitted the form on page 63 and i want the value to be passed to the other page how can i do so??
Kindly throw some light on this.........
function validate()
{
$('#first_name').focus();
// var TYUrl = $('#TY_Url').val();
// alert($('#TY_Url'));
var valid =true;
var WebRequestInfo=document.getElementById('elq_form');
if(valid && WebRequestInfo.email.value=='')
{
alert('Please enter your email address.');
WebRequestInfo.email.focus();
valid=false;
return false;
}
if (valid && WebRequestInfo.first_name.value=='') {
alert('Please enter your first name.');
WebRequestInfo.first_name.focus();
valid=false;
return false;
}
if (valid && WebRequestInfo.last_name.value=='') {
alert('Please enter your last name.');
WebRequestInfo.last_name.focus();
valid=false;
return false;
}
if(valid=true)
{
var TYUrl = $('#TY_Url').val();
TYUrl += "?first_name=" + encodeURIComponent($("#first_name").val()) + "&last_name=" + encodeURIComponent($("#last_name").val()) + "&email=" + encodeURIComponent($("#email").val());
$('#TY_Url').val(unescape(TYUrl));
document.forms[0].submit()
}
return valid;
}
For client-Side , you could use cookies to save these data. Then on every page reload you could load them.
You can find here how to use cookies with javascript : http://www.w3schools.com/js/js_cookies.asp
Another way could be to use session data but you need to do some server side work there.
How about localStorage for HTML5? Data will be saved on client side.

I am trying to use JavaScript to redirect to a PHP page on my site, however, when I do it, nothing happens, apart from the alert boxes if I do not fill in the parameters. Is there something I am doing wrong?
document.getElementById("submit").onclick = check;
function check()
{
if(document.getElementById("name").value == "")
alert("The field 'Name' is required.");
else if (document.getElementById("message").value == "")
alert("The field 'Message' is required");
else
window.location.href = "scripts/main/contact.php?msg=" + document.getElementById("message").value;
}
Your default form action takes place overriding your redirect. Return false from the handler to prevent it from taking place:
function check()
{
if(document.getElementById("name").value == "")
alert("The field 'Name' is required.");
else if (document.getElementById("message").value == "")
alert("The field 'Message' is required");
else
window.location.href = "scripts/main/contact.php?msg=" + document.getElementById("message").value;
return false; // <------ here
}
I have this email form validation script:
<script type="text/javascript" language="javascript">
function validateForm(thisform){
if(thisform.Name.value=="") {
alert("Ooouuupppsss... You did not enter your Name.");
thisform.Name.focus();
return false;
}
if(thisform.Email.value=="") {
alert("Ooouuupppsss... You did not enter a valid Email Address.");
thisform.Email.focus();
return false;
}
if(thisform.Subject.value=="") {
alert("Ooouuupppsss... You did not enter your Subject.");
thisform.Subject.focus();
return false;
}
if(thisform.Message.value=="") {
alert("Ooouuupppsss... You did not enter your Message.");
thisform.Message.focus();
return false;
}
}</script>
Can someone please tell me what do I have to add in this script in order to make the users enter a valid email address. Also I would like in the rest of the fields to make users to enter text (not links).
I've tried to add different pieces of code which I found on different websites but they did not work and this is because I am not sure if I am adding them right.
Thank you for reading my request.
All the best,
Andi
For e-mail checking you can use following code in else part after checking if e-mail is empty
function validateForm(){
var email = document.getElementById("email").value;
var emailRegEx = /^[A-Z0-9._%+-]+#[A-Z0-9.-]+\.[A-Z]{2,4}$/i;
if (email.search(emailRegEx) == -1) {
alert("e-mail is not valid");
return false;
}
}
and for url with same logic you can use following regular expression
var urlRegEx = /((([A-Za-z]{3,9}:(?:\/\/)?)(?:[-;:&=\+\$,\w]+#)?[A-Za-z0-9.-]+|(?:www.|[-;:&=\+\$,\w]+#)[A-Za-z0-9.-]+)((?:\/[\+~%\/.\w-_]*)?\??(?:[-\+=&;%#.\w_]*)#?(?:[\w]*))?)/;
following is a working example based on your work, you can improve this code it is only for showing you how it should be.
function validateForm(thisform){
if(thisform.Name.value=="") {
alert("Ooouuupppsss... You did not enter your Name.");
thisform.Name.focus();
return false;
}
else{
var name = thisform.Name.value;
if (!checkURL(name)) {
alert("name cannot be a url");
return false;
}
}
if(thisform.Email.value=="") {
alert("Ooouuupppsss... You did not enter a valid Email Address.");
thisform.Email.focus();
return false;
}
else{
var email = thisform.Email.value;
var emailRegEx = /^[A-Z0-9._%+-]+#[A-Z0-9.-]+\.[A-Z]{2,4}$/i;
if (email.search(emailRegEx) == -1) {
alert("e-mail is not valid");
return false;
}
}
if(thisform.Subject.value=="") {
alert("Ooouuupppsss... You did not enter your Subject.");
thisform.Subject.focus();
return false;
}
else{
if (!checkURL(thisform.Subject.value)) {
alert("subject cannot contain a url");
return false;
}
}
if(thisform.Message.value=="") {
alert("Ooouuupppsss... You did not enter your Message.");
thisform.Message.focus();
return false;
}
else{
if (!checkURL(thisform.Message.value)) {
alert("message cannot contain a url");
return false;
}
}
}
function checkURL(url){
var urlRegEx = /((([A-Za-z]{3,9}:(?:\/\/)?)(?:[-;:&=\+\$,\w]+#)?[A-Za-z0-9.-]+|(?:www.|[-;:&=\+\$,\w]+#)[A-Za-z0-9.-]+)((?:\/[\+~%\/.\w-_]*)?\??(?:[-\+=&;%#.\w_]*)#?(?:[\w]*))?)/;
if (url.search(urlRegEx) == -1) {
return true;
}
return false;
}
See this post for regex urls: regular expression for url
See this post for email validation: Validate email address in JavaScript?
See this for X browser event listening, if would use jQuery, ie8 uses attach see this: Javascript add events cross-browser function implementation: use attachEvent/addEventListener vs inline events
I would recommend looping through the form inputs, and checking if its email and if its not run the regex against the link.
(function(){
var validateForm = function(form){
var errors = [], inputs = form.getElementsByTagName('input');
for(var input = 0; input<inputs.length; input++){
var currentInput = inputs[input];
if(currentInput.value === ''){
// handle attributes here for error message, push error message
if(currentInput.attribute('name') === 'email'){
// handle email
// push error message
}
}
}
return errors;
}
var contactForm = document.getElementById('contact');
contactForm.addEventListener('submit', function(e){
var errorMessages = validateForm(contactForm);
if(errorMessages.length === 0){
} else {
e.preventDefault() // stop the form from submitting
// handle your messages
}
}
}());
I'm in the middle of coding CAPTCHA in JavaScript, and I'm trying to get the validation for a contact form to work properly. I'm almost there, the form won't be submitted until the CAPTCHA text-field is entered, but the problem is I'm still getting an error message when I entered the CAPTCHA code correctly.
<script>
function ValidateContactForm()
{
var name = document.ContactForm.name;
var phone = document.ContactForm.phone;
var code = document.ContactForm.code;
if (name.value == "")
{
window.alert("Please enter your name.");
name.focus();
return false;
}
if (phone.value == "")
{
window.alert("Please enter a valid phone number..");
phone.focus();
return false;
}
if (code.value == "")
{
window.alert("Please enter the code as displayed on screen.");
code.focus();
return false;
}
else if (code.value != "")
{
window.alert("Your code does not match. Please try again.");
code.focus();
return false;
}
else {
return true;
}
return true;
}
</script>
Any help would be greatly appreciated. Thanks.
Check this lines, the problem is here:
if (code.value == "")
{
window.alert("Please enter the code as displayed on screen.");
code.focus();
return false;
}
else if (code.value != "")
{
window.alert("Your code does not match. Please try again.");
^^^^^^^^^^^^^
code.focus();
^^^^^^^^^^^^^
return false;
^^^^^^^^^^^^^
}
else {
return true;
}
This code will return false every time.
