Hello I have this function right here:
function formCheck() {
var valid = true;
var error;
resetBorders('.customer-create-form');
$('.customer-create-form :input[required]').each(function() {
if ($(this).val().length == 0) {
valid = false;
error = "* Alle felter skal udfyldes";
$(this).css('border-color', 'red');
}
});
if ($('input[name="postal_code"]').val().length != 0 && !$.isNumeric($('input[name="postal_code"]').val())) {
valid = false;
error = "* Ugyldig post nummer";
$('input[name="postal_code"]').css('border-color', 'red');
}
if (valid == true) {
return true;
} else {
$('.error-firm-settings-1-form').html(error);
}
return false;
}
I want to set this into a function for itself, but when I do it and update the valid to false, the formCheck() does not register it, and it continues. How do I do so it set it to false in the formCheck() function.
if ($('input[name="postal_code"]').val().length != 0 && !$.isNumeric($('input[name="postal_code"]').val())) {
valid = false;
error = "* Ugyldig post nummer";
$('input[name="postal_code"]').css('border-color', 'red');
}

Trying to make an address book for school and entered two fields and having validation. It seems like it's only validating the first field which is the name and ignoring the rest? I'm not sure if I have something wrong? It keeps displaying not a valid name as the error message and nothing else.
var validate_birthdate = my.isBirthdateBad(add_birthdate);
if (!valid_name.test(add_name)) {
alert("not a valid name");
valid_contact = false;
} else if (add_address.length > 0) {
if (!valid_address.test(add_address)) {
alert("not a valid address: " + add_address);
valid_contact = false;
}
} else if (add_birthdate.length > 0) {
if (!valid_birthdate.test(add_birthdate)) {
alert("not a valid birthdate");
valid_contact = false;
}
} else if (add_gender.length > 0) {
if (!valid_gender.test(add_gender)) {
alert("not a valid gender");
valid_contact = false;
}
} else if (add_ocupation.length > 0) {
if (!valid_occupation.test(add_occupation)) {
alert("not a valid job title");
valid_contact = false;
}
} else if (validate_birthdate) {
alert("not a valid birthdate: " + validate_birthdate);
valid_contact = false;
} else if (!(add_photo !== undefined) &&
(add_photo.length > 0) &&
(add_photo.indexOf("data:image/jpeg") === 0)) {
alert("image is not a jpeg!");
valid_contact = false;
}
// note the use of the "anonymous" function
// this returns an array of all of the matched contacts! Powerful!
var exists = _address_book_contacts.filter(function (contact) {
//check to see if the current "add_name"
// is found in the address book!
return contact.name() === add_name;
});
if (exists && (exists.length > 0)) {
if (!confirm("WARNING: " +
add_name +
" exists in database. " +
"Would you like to add again?")) {
valid_contact = false;
}
}
I have some problem when I check the function validation, I need when checking all the cassis is true hide the parent div * errors message *
var error_pass = false;
$('#pass').focusout(function(){
check_pass();
error_pass = false;
if(error_pass !== true){
console.log('its showing!');
}else{
$('.test').fadeOut('522');
}
});
function check_pass() {
var fpass= $('#pass').val();
switch(error_pass = true){
case(fpass.length < 6 ? $('#pass-error-message3').css('color','red'):$('#pass-error-message3').css('color','green') ):
$('#pass-error-message3').show();
case(fpass.search(/(?=.[a-z])(?=.*[A-Z])/) == -1 ? $('#pass-error-message4').css('color','red') : $('#pass-error-message4').css('color','green')):
$('#pass-error-message4').show();
case(fpass.search(/\d/) == -1 ? $('#pass-error-message2').css('color','red'):$('#pass-error-message2').css('color','green')):
$('#pass-error-message2').show();
default:break;
}
}
Use if else statements like this
function validation() {
var error = false;
if (fpass.length < 6) {
error = true;
$('#pass-error-message3').css('color', 'red').show();
} else {
$('#pass-error-message3').css('color', 'green');
}
if (fpass.search(/(?=.[a-z])(?=.*[A-Z])/) == -1) {
error = true;
$('#pass-error-message4').css('color', 'red').show();
} else {
$('#pass-error-message4').css('color', 'green')
}
if(fpass.search(/\d/) == -1){
error = true;
$('#pass-error-message2').css('color','red').show();
}else{
$('#pass-error-message2').css('color','green');
}
if(error === false){
hideParentDiv(); // Here hide the div
}
}
Much cleaner approach
I am having a hard time trying to do a correct form validation. I have Name, Email, and Phone Number fields. I implemented the validation check for all of them and when I click on the submit query, it returns email as false, but not anything else. It also will still submit the form. How do I fix this?
JSFiddle: http://jsfiddle.net/GVQpL/
JavaScript Code:
function validateForm(/*fullName, email, phoneNumber*/)
{
//-------------------------NAME VALIDATION-----------------------------//
var fullNameV = document.forms["queryForm"]["fullName"].value;
if (fullNameV == null || fullNameV == "")
{
alert("Name must be filled out!");
return false;
}
else if(fullNameV.indexOf(" ") <= fullNameV.length)
{
alert("Not a valid name");
return false;
}
//-------------------------EMAIL VALIDATION-----------------------------//
var emailV = document.forms["queryForm"]["email"].value;
if (emailV == null || emailV == "")
{
alert("Email must be filled out!");
return false;
}
var atpos = emailV.indexOf("#");
var dotpos = emailV.lastIndexOf(".");
if (atpos < 1 || dotpos < atpos + 2 || dotpos + 2 >= x.length)
{
alert("Not a valid e-mail address");
return false;
}
//-------------------------PHONE # VALIDATION-----------------------------//
var phoneNumberV = document.forms["queryForm"]["phoneNumber"].value;
if (phoneNumberV == null || phoneNumberV == "")
{
alert("Phone Number must be filled out!");
return false;
}
var error = "";
var stripped = phoneNumberV.replace(/[\(\)\.\-\ ]/g, '');
if (phoneNumberV == "")
{
error = alert("You didn't enter a phone number.\n");
phoneNumberV.style.background = 'Yellow';
}
else if (isNaN(parseInt(stripped)))
{
error = alert("The phone number contains illegal characters.\n");
phoneNumberV.style.background = 'Yellow';
}
else if (!(stripped.length == 10))
{
error = alert("The phone number is the wrong length. Make sure you included an area code.\n");
phoneNumberV.style.background = 'Yellow';
}
return error;
}
Update your fiddle's html for the function to be called onsubmit="return validateForm()" and removed the required="required" changed your function to work, you can see it here:
http://jsfiddle.net/GVQpL/3/
function validateForm(/*fullName, email, phoneNumber*/)
{
//-------------------------NAME VALIDATION-----------------------------//
var fullNameV = document.forms["queryForm"]["fullName"].value;
if (fullNameV == null || fullNameV == "")
{
alert("Name must be filled out!");
document.forms["queryForm"]["fullName"].focus();
return false;
}
else if(fullNameV.indexOf(" ") >= fullNameV.length)
{
alert("Not a valid name");
document.forms["queryForm"]["fullName"].focus();
return false;
}
//-------------------------EMAIL VALIDATION-----------------------------//
var emailV = document.forms["queryForm"]["email"].value;
if (emailV == null || emailV == "")
{
alert("Email must be filled out!");
document.forms["queryForm"]["email"].focus();
return false;
}
var emailReg = /^([\w-\.]+#([\w-]+\.)+[\w-]{2,4})?$/;
if(!emailReg.test(emailV)){
alert("Not a valid e-mail address");
document.forms["queryForm"]["email"].focus();
return false;
}
//-------------------------PHONE # VALIDATION-----------------------------//
var phoneNumberV = document.forms["queryForm"]["phoneNumber"].value;
if (phoneNumberV == null || phoneNumberV == "")
{
alert("Phone Number must be filled out!");
document.forms["queryForm"]["phoneNumber"].focus();
return false;
}
var error = "";
var stripped = phoneNumberV.replace(/[\(\)\.\-\ ]/g, '');
if (phoneNumberV == "")
{
alert("You didn't enter a phone number.\n");
document.forms["queryForm"]["phoneNumber"].focus()
document.forms["queryForm"]["phoneNumber"].style.background = 'Yellow';
return false;
}
else if (isNaN(parseInt(stripped)))
{
alert("The phone number contains illegal characters.\n");
document.forms["queryForm"]["phoneNumber"].focus();
document.forms["queryForm"]["phoneNumber"].style.background = 'Yellow';
return false;
}
else if (!(stripped.length == 10))
{
alert("The phone number is the wrong length. Make sure you included an area code.\n");
document.forms["queryForm"]["phoneNumber"].focus();
document.forms["queryForm"]["phoneNumber"].style.background = 'Yellow';
return false;
}
if(!confirm('Are you sure you want to submit your DSLR query?')){
return false;
}
return true;

I have created a form that validates using JQuery and JavaScript. The only problem is, would be that it validates one field at a time. So the user has to correct the first field first and then press submit again to see if the next field is valid.
What I would like to to do, is have the JQuery validate the whole form after pressing submit and show all the applicable error messages.
Here is My JS:
function validateUserName()
{
var u = document.forms["NewUser"]["user"].value
var uLength = u.length;
var illegalChars = /\W/; // allow letters, numbers, and underscores
if (u == null || u == "")
{
$("#ErrorUser").text("You Left the Username field Emptyyy");
return false;
}
else if (uLength < 4 || uLength > 11)
{
$("#ErrorUser").text("The Username must be between 4 and 11 characters");
return false;
}
else if (illegalChars.test(u))
{
$("#ErrorUser").text("The Username contains illegal charectors men!");
return false;
}
else
{
return true;
}
}
function validatePassword()
{
var p = document.forms["NewUser"]["pwd"].value
var cP = document.forms["NewUser"]["confirmPwd"].value
var pLength = p.length;
if (p == null || p == "")
{
$("#ErrorPassword1").text("You left the password field empty");
return false;
}
else if (pLength < 6 || pLength > 20)
{
$("#ErrorPassword1").text("Your password must be between 6 and 20 characters in length");
return false;
}
else if (p != cP)
{
$("#ErrorPassword1").text("Th passwords do not match!");
return false;
}
else
{
return true;
}
}
function validateEmail()
{
var e = document.forms["NewUser"]["email"].value
var eLength = e.length;
var emailFilter = /^[^#]+#[^#.]+\.[^#]*\w\w$/;
var illegalChars = /[\(\)\<\>\,\;\:\\\"\[\]]/;
if (eLength == "" || eLength == null)
{
$("#ErrorEmail").text("You left the email field blank!");
return false;
}
else if (e.match(illegalChars))
{
$("#ErrorEmail").text("ILEGAL CHARECTORS DETECTED EXTERMINATE");
return false;
}
else
{
return true;
}
}
function validateFirstName()
{
var f = document.forms["NewUser"]["fName"].value;
var fLength = f.length;
var illegalChars = /\W/;
if (fLength > 20)
{
$("#ErrorFname").text("First Name has a max of 20 characters");
return false;
}
else if (illegalChars.test(f))
{
$("#ErrorFname").text("Numbers,letter and underscores in first name only");
return false;
}
else
{
return true;
}
}
function validateLastName()
{
var l = document.forms["NewUser"]["lName"].value;
var lLength = l.length;
var illegalChars = /\W/;
if (lLength > 100)
{
$("#ErrorLname").text("Last Name has a max of 100 characters");
return false;
}
else if (illegalChars.test(f))
{
$("#ErrorLname").text("Numbers,letter and underscores in last name only");
return false;
}
else
{
return true;
}
}
function validateForm()
{
valid = true;
//call username function
valid = valid && validateUserName();
//call password function
valid = valid && validatePassword();
//call email function
valid = valid && validateEmail();
//call first name function
valid = valid && validateFirstName();
//call first name function
valid = valid && validateLastName();
return valid;
}
And here is my submit form code:
$('#your-form').submit(validateForm);
Instead of returning true or false return a string containing the error and an empty string if no error was found.
Then validateForm could be something like
function validateForm()
{
error = "";
//call username function
error += "\n"+validateUserName();
//call password function
error += "\n"+validatePassword();
...
if(error === ""){
return true;
}
$("#ErrorLname").text(error);
return false;
}

You need to access all the fields and check if the field is valid r not. If the field is valid skip it, otherwise put the field in an array. When all the fields have been checked, then display the error fields from the array all at one time.
I am trying to validate my form on submit and if the input's are all filled in they submit to register.php
My problem being it only works if all inputs are blank - otherwise it errors - I'm just trying to check if any of those fields are blank before submiting
function submitform() {
if ($('#name, #email, #user, #address, #phone').val().length === 0) {
$(this).addClass('warning');
} else {
alert("form submitted");
}
}
You cant do a .val on an array. It should be
function submitform(){
var warning = false;
$('#name, #email, #user, #address, #phone').each(function() {
$(this).val().length === 0){
warning = true;
return;
}
});
if(warning) {
$(this).addClass('warning');
} else {
alert("form submitted");
}
}
you need to check each one of them with the each function in jquery, or a for loop.
$('#name, #email, #user, #address, #phone').each(function(){
if ($(this).val().length === 0){
$(this).addClass('warning');
} else {
alert("form submitted");
}
});
Here's the same example with a for
var formElements = $('#name, #foo');
for (i = 0 ; i < formElements.length ; i++)
{
if ( $(formElements[i]).val().length === 0 )
$(this).addClass('warning');
else {
alert("form submitted");
}
}
function formSubmit() {
var pass = true;
jQuery.each( jQuery('#form :input'), function( key, value ) {
if(!this.value && jQuery(this).attr('class :contains("required")')) {
if (jQuery(this).siblings('.error').length === 0 && jQuery(this).type != 'submit') {
jQuery(this).after('<label class="error"><span class="form-required">*</span> Required</label>');
}
pass = false;
} else {
jQuery(this).siblings('.error').remove();
}
});
if (pass === true) {
document.getElementById('form').submit();
}
}
