javascript validation does not work - javascript

validateType(), validateStatus(), validateMessage() does not work.
any ideas?
validateEmail() and validateName() works.
I been trying to debug this for a while without any luck. I have exhausted myself.
Thank you for the help!
The form is called contact.

remove
if (validateSubject() == false)
{
return false;
}
You haven't defined a validateSubject() function


you dont have a function named validateSubject()
which is called here
if (validateSubject() == false)
{
return false;
}


function javaScriptValidation()
{
return validateName() && validateEmail() && validateSubject() && validateType() && validateStatus() && validateMessage();
}
Add ValidateSubject() implementaion and change:
function validateName()
{
var letters = /^[A-Za-z]+$/;
if (!letters.test(name1.value))
{
alert("Invalid Name (only letters)");
name1.focus();
return false;
}
return true; //add this line to each method
}


please replace with the following js
function javaScriptValidation(form) {
var namePattern = /^[A-Za-z]+$/;
var emailPattern = /^([a-zA-Z0-9_\.\-])+\#(([a-zA-Z0-9\-])+\.)+([a-zA-Z0-9]{2,4})+$/;
// name
if (!namePattern.test(form.name.value)){
alert("Invalid Name (only letters)");
form.name.focus();
return false;
}
//email
if (!emailPattern.test(form.email.value)){
alert("Invalid Email");
form.email.focus();
return false;
}
//type
if(form.type.selectedIndex == 0){
alert("You must select the reason to contact");
form.type.focus();
return false;
}
//status
if((form.status[0].checked == false) && (form.status[1].checked == false) && (form.status[2].checked == false) && (form.status[3].checked == false)){
alert("Please select your status");
return false;
}
//subject
if (!namePattern.test(form.subject.value)){
alert("please write a subject");
form.subject.focus();
return false;
}
//message
if (!namePattern.test(form.message.value)){
alert("please write a message");
form.message.focus();
return false;
}
return true;
}
add name for select box
<select id="type1" class="type" name="type">
add this on form tag onsubmit validation
<form name="contact" method="post" action="" onsubmit="return javaScriptValidation(this)">

how to get external form validation to work with jQuery

Okay, I'm trying to get a contact form to work and it is, sort of. The data is passing through, but I can't get the jQuery to work. If I type in two different email addresses it doesn't catch it. Here is the relevant code I used:
HTML
<aside>
<form action="sendmail.php" method="post" name="contact_form" id="contact_form">
<fieldset>
<legend>sign up now!</legend><br>
<p>Sign up for my email list and get a free mini coloring book!</p><br>
<img src="Images/minicoloirngbook.jpg" alt="mini coloring book"><br>
<label for="name"> Name:</label>
<input type="text"name="name" id="name" required><span>*</span><br>
<label for="email">Email Address:</label>
<input type="email" name="email" id="email" required><span>*</span><br>
<label for="verify">Verify Email:</label>
<input type="email" name="verify" id="verify" required> <span>*</span><br>
<div id="buttons">
<input type="submit" id="submit" value="Sign Up">
</div>
</fieldset>
</form>
</aside>
and here is the Javascript:
$("#contact_form").submit(event => {
let isValid = true;
// validate the first name entry
const name = $("#name").val().trim();
if (name == "") {
$("#name").next().text("This field is required.");
isValid = false;
} else {
$("#name").next().text("");
}
$("#name").val(name);
// validate the email entry with a regular expression
const emailPattern = /\b[A-Za-z0-9._%+-]+#[A-Za-z0-9.-]+\.[A-Za-z]{2,4}\b/;
const email = $("#email").val().trim();
if (email == "") {
$("#email").next().text("This field is required.");
isValid = false;
} else if ( !emailPattern.test(email) ) {
$("#email").next().text("Must be a valid email address.");
isValid = false;
} else {
$("#email").next().text("");
}
$("#email").val(email);
// validate the verify entry
const verify = $("#verify").val().trim();
if (verify == "") {
$("#verify").next().text("This field is required.");
isValid = false;
} else if (verify !== email) {
$("#verify").next().text("Must match first email entry.");
isValid = false;
} else {
$("#verify").next().text("");
}
$("#verify").val(verify);
// prevent the submission of the form if any entries are invalid
if (isValid == false) {
event.preventDefault();
}
}),
I think that the answer is probably something really simple that I can't see and would appreciate your help in figuring it out.

This should do it. Here is the jsfiddle if you like to play with the code: https://jsfiddle.net/bogatyr77/xk6ez3aq/7/
$("form").submit(function(e) {
var name = $("#a").val();
if (name == "") {
$("#nameerror").text("This field is required.");
alert('false');
} else {
alert('true');
$("#nameerror").remove();
}
//email1
var emailPattern = /\b[A-Za-z0-9._%+-]+#[A-Za-z0-9.-]+\.[A-Za-z]{2,4}\b/;
const email = $("#b").val();
if (email == "") {
$("#email1error").text("This field is required.");
isValid = false;
} else if (!emailPattern.test(email)) {
$("#email1error").text("Must be a valid email address.");
isValid = false;
} else {
$("#email1error").remove();
}
//eamil 2
var verify = $("#c").val();
if (verify == "") {
$("#email2error").text("This field is required.");
isValid = false;
} else if (verify !== email) {
$("#email2error").text("Must match first email entry.");
isValid = false;
} else {
$("#email2error").remove();
}
if (isValid == false) {
event.preventDefault();
}
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<form action="javascript:alert('ok')">
<label for="name"> Name:</label>
<input type="text" name="name" id="a"><span>*</span>

2 Functions have to be true to submit the form. (Javascript)

So the two Functions (chForumular() and validate_user_text()) have both to be true to submit the form. Right now you cant send the form without fil in the username, age(in the code Alter) and your E-Mail. but the second function (validate_user_text) should check if there is any swear word in the message (=Nachricht) right know it submits the form after you fil in the three fields (e-mail, name and age). iven if you type in an swearword in the textarea. (something like: sorry ((asshole)))
If you dont understand a Word you think could be important just write the word to me so I can translate...(German and Swissgerman Words in the Code)
Here is my code so far:

// document.Formular.Ort.focus();

if (document.Formular.Mail.value == "") {

document.Formular.Mail.focus();
return false;

There are much better ways to do this. This is not an elegant way. I see this code is from an example or tutorial. Please check other tutorials on this subject, as this is just a quick way of implementing what you want.

Onclick Validation not working

I've been working on this assignment for the longest while. My form validations weren't working previously but then I found out what the error was & everything was working perfectly.
Later on, I had made some changes to the code then deleted those changes and now the validations aren't working again & I can't seem to find what the problem is this time.
Below is my unfinished code:
function validateEmail() {
var email = document.getElementById('email').value;
if( email==null || email=="")
{
alert("Please input an email address");
}
}
function validateFName() {
var firstname = document.getElementById('firstname').value;
if( firstname==null || firstname=="")
{
alert("Please input a last name");
return false;
}
}
function validateLName() {
var lastname = document.getElementById('lastname').value;
if( lastname==null || lastname=="")
{
alert("Please input a last name");
}
}
function validateGender() {
var gender = document.getElementById('gender').value;
if( gender==null || gender=="")
{
alert("Please select a gender");
}
}
function validateDate() {
var date = document.getElementById('date').value;
if( date==null || date=="")
{
alert("Please select a date");
}
}
function validateVName() {
var vname = document.getElementById('vname').value;
if( vname==null || vname=="")
{
alert("Please input a victim's name");
}
}
function validateVEmail() {
var vemail = document.getElementById('vemail').value;
if( vemail==null || vemail=="")
{
alert("Please input a victim's email");
}
}
<div id="navi">
<nav>
<ul class="fancyNav">
<li id="home">Home</li>
<li id="news">TRUTH</li>
<li id="about">DARE</li>
</ul>
</nav>
</div>
<div id="box">

<input type="submit" onclick="validateFName(); validateLName(); validateGender(); validateDate(); validateVName(); validateVEmail();" /> <br>
</form>
</div>

<input type="submit" onclick="validateFName(); validateLName(); validateGender(); v
typo in function name, onclick="validateFName()...
it should be validateLName()
and you define duplicate
<!DOCTYPE html>
<html> // remove this one

The best possible solution would be to not use any alert boxes at all but instead embed the error message next to the place of the error, but that would be more involved. Instead, to stick with this solution, first add an id to your submit button:
<button type="submit" id="truth-submit">Submit</button>
Then, attach an onclick handler through JavaScript (and rewrite your code to be more re-usable):
// Only run when the window fully loads
window.addEventListener("load", function() {
function validateEmail() {
var email = document.getElementById("email").value;
if (email === null || email === "") {
return "Please input an email address";
}
return "";
}
function validateFName() {
var firstname = document.getElementById("firstname").value;
if (firstname === null || firstname === "") {
return "Please input an first name";
}
return "";
}
function validateLName() {
var lastname = document.getElementById("lastname").value;
if (lastname === null || lastname === "") {
return "Please input an last name";
}
return "";
}
function validateGender() {
var gender = document.getElementById("gender").value;
if (gender === null || gender === "") {
return "Please select a gender";
}
return "";
}
function validateDate() {
var date = document.getElementById("date").value;
if (date === null || date === "") {
return "Please select a date";
}
return "";
}
function validateVName() {
var vname = document.getElementById("vname").value;
if (vname === null || vname === "") {
return "Please input a victim's name";
}
return "";
}
function validateVEmail() {
var vemail = document.getElementById("vemail").value;
if (vemail === null || vemail === "") {
return "Please input a victim's email";
}
return "";
}
document.getElementById("truth-submit").addEventListener("click", function(event) {
// Grab all of the validation messages
var validationMessages = [validateFName(), validateLName(),
validateGender(), validateDate(), validateVName(), validateVEmail()];
var error = false;
// Print out the non-blank ones
validationMessages.forEach(function(message) {
if (message) {
alert(message);
error = true;
}
});
// Stop submission of the form if an error occurred
if (error) {
event.preventDefault();
}
}, false);
}, false);

Javascript validation is not working in html registration form

I am using php mysql for user registration. I have added javascript validation to check if any field is blank or not. But the form validation is not working. the form is

Please help me.

Lets have a look at your function valide()
It has some mistakes and it does not return true when everything is ok...
Since it does not return true, form is not submitted...
Here is a corrected version:
function valide(){
var fname=document.forms["regForm"]["fname"].value;
var username=document.forms["regForm"]["username"].value;
var subject = document.forms["regForm"]["background"].value;
var password=document.forms["regForm"]["password"].value;
var conpassword=document.forms["regForm"]["conpassword"].value;
var email=document.forms["regForm"]["email"].value;
var atpos=email.indexOf("#");
var dotpos=email.lastIndexOf(".");
// Let me warn you:
// There are many many people with names less than 7 characters
if (fname==null || fname=="" || fname.length<7) {
alert("Please provide Your full name");
return false;
} // if returned so else is not required
if (username==null || username==""){
if(username.length<6){
alert("Username must contains atleast 6 charecters");
} else
alert("Please provide a username");
return false;
} // if returned so else is not required
if(subject==null || subject == ""){
alert("Enter Background");
return false;
} // if returned so else is not required
if (password == null || password==""){
// length = 0 or password is null here so:
// if(password.length<8) is unnecessary
if(password == ""){
alert("Password must contain at least 8 charecters");
} else
alert("Please insert your password");
return false;
} // if returned so else is not required
if (conpassword != password){
alert("Confirm password doesn't match");
return false;
} // if returned so else is not required
if (email==null || email==""){
alert("Email must be filled out.");
return false;
} // if returned so else is not required
if (atpos <1 || (dotpos <atpos+2) || (dotpos + 2 >= email.length)){
alert("Not a valid e-mail address");
return false;
} // if returned no else needed.
// and now this function should return:
return(true);
}
