Phone Number Regex Validation error while showing/hiding Elements

I am working on a form where I am showing a div when a user submits the form and it checks if all the fields values are not blank. I have achieved that part and it is working fine.
Now the problem is when I am validating the phone number using regex, it is showing error but still displays the div and form is also submitted successfully. It should not get submit till the user enters a correct phone number, it gives an error and still, the form gets submitted. I know the error is there but I am not understanding where I am wrong. Please guide me.
function mySub() {
const user = document.getElementById('pmname').value.trim();
const uemail = document.getElementById('pmemail').value.trim();
const uphone = document.getElementById('pmphone').value.trim();
const uregx = /^[0-9]{10}$/;
const upmmb = uregx.test(uphone);
if (user == "" || uemail == "" || uphone == "" || upmmb == "") {
document.getElementById('agy').style.display = 'none';
alert("Enter Valid Mobile Number");
document.getElementById('pmphone').focus();
} else {
document.getElementById('agy').style.display = 'block';
}
}
#agy {
display: none;

How to trigger default Bootstrap 4 form validation error message from custom external script

In our contact form, I'm trying to only allow submissions from email addresses from the United States, since we can only do business in that one country. How can I trigger the default error message when a form submit attempt is made, so that "invalid" message appears the same way it appears for the first name and last name fields?
In the code below, for the sake of example, I'm allowing only 'com', 'edu', 'gov', 'net', 'org'. The goal is to trigger a message whenever an email address other than those above is entered into the email field.
$(document).ready(function() {
$(function() {
$("#testform").submit(function() {
str = $('input[name=emailAddress]').val();
str = str.split('#').slice(0);
str = str[1].split('.').slice(0);
var allowedDomains = ['com', 'edu', 'gov', 'net', 'org'];
alert("str = " + str[1]);
if ($.inArray(str[1], allowedDomains) !== -1) {
alert(str + ' is allowed');
} else {
alert('not allowed');
event.preventDefault();
event.stopPropagation();
$('#emailAddress').addClass('invalid');
}
});
});
});

jQuery form validation fails only on a specific input

I have a fairly straightforward validation function that only checks if input is empty or not. I'm using it across a half dozen different forms and it seems to be working everywhere except one specific input id="driver_first_name" . Can't figure out why it fails there.
If I leave all fields empty I get errors on all of them, and is generally correct across any combination I have tried except driver_first_name In the case that I fill out everything except driver_first_name the form submits anyways.
Any insight on what might be going on here?
Thank you!
My Validation function is this:
function validateForm(form, fields) { //add exit anbimation and reset the container state
$(".form-input-error").remove();
var result=false;
$.each( fields.rules, function( key, value ) {
if(!$("#"+key+"").val()){
$("#"+key+"").addClass("form-error");
$( "<div class='form-input-error'>"+value.message+"</div>" ).insertBefore("#"+key+"");
result = false;
//console.log(this.val());
}
else{
$("#"+key+"").removeClass("form-error");
result = true;
}
});
return result;
}
I am calling my validation on my submit triggers, generally like this for fields that should not be empty:
$(".app-canvas").on('click', ".submitNewDriver", function () {//list all drivers trigger
var checkInputs = {
rules: {
driver_first_name: {
message: "First Name is Required"
},
driver_last_name: {
message: "Last Name is Required"
},
driver_address_street: {
message: "street is Required"
}
}
};
if(validateForm($("#addDriverForm"),checkInputs) == true){
console.log("form submit");
addNewDriver();
}
else{
console.log("form errors");
}
});
My full form HTML is

Your validation logic is a little messed up. This is what's happening:
#driver_first_name is validated as invalid... result is set false
#driver_last_name is validated as valid... result is set true
#driver_address_street is validated as valid... result is set true
After all that the code thinks the form is valid. You're only preventing the form from being submitted if the last field as validated as not-valid.
Change your logic to assume the form is valid from the beginning. Then set it to false if any of the fields are invalid.
I also don't see anything in your code that actually prevents the form submition, so I also added e.preventDefault()
function validateForm(form, fields) { //add exit anbimation and reset the container state
$(".form-input-error").remove();
var result = true;
$.each(fields.rules, function(key, value) {
if (!$("#" + key + "").val()) {
$("#" + key + "").addClass("form-error");
$("<div class='form-input-error'>" + value.message + "</div>").insertBefore("#" + key + "");
result = false;
//console.log(this.val());
} else {
$("#" + key + "").removeClass("form-error");
}
});
return result;
}
$(".app-canvas").on('click', ".submitNewDriver", function(e) { //list all drivers trigger
var checkInputs = {
rules: {
driver_first_name: {
message: "First Name is Required"
},
driver_last_name: {
message: "Last Name is Required"
},
driver_address_street: {
message: "street is Required"
}
}
};
if (validateForm($("#addDriverForm"), checkInputs) == true) {
console.log("form submit");
} else {
e.preventDefault();
console.log("form errors");
}

Javascript code:
<script>
function ValidationEvent() {
var email = document.getElementById("email").value;
var username = document.getElementById("username").value;
var cemail = document.getElementById("cemail").value;
// Conditions
if (email.match != cemail.match) {
alert("Your email doesn't match!");
}
if(mysqli_num_rows($result) != 0)
{
alert("Username already taken!");
}
else {
alert("Thank you");
}
}
</script>
Am I approaching the function in the wrong way is there another easier way and is it okay i put an sql statement in my java script ?

First, don't use inline HTML event handling attributes (like "onsubmit") as they create "spaghetti code", anonymous global event handling wrapper functions and don't conform to the modern W3C DOM Event handling standard.
Second, your .php results have to be gotten from somewhere. You'll need to put a call into that file for its results before you can use them.
Next, you were using the .match() string method incorrectly to compare the emails against each other. All you really need to do is compare the values entered into the email fields (it's also a good idea to call .trim() on form values to strip out any leading or trailing spaces that might have been inadvertently added).
Once you restructure your code to use standards, the JavaScript will change as follows (FYI: This won't work in the Stack Overflow snippet environment because form submissions are blocked, so you can see a working version here):
// When the DOM is loaded:
window.addEventListener("DOMContentLoaded", function(){
// Get references to the DOM elements you will need:
var frm = document.getElementById("frm");
// Don't set variables to the values of DOM elements,
// set them to the DOM elements themselves so you can
// go back and get whatever properties you like without
// having to scan the DOM for them again
var email = document.getElementById("email");
var username = document.getElementById("username");
var cemail = document.getElementById("cemail");
// Set up a submit event handler for the form
frm.addEventListener("submit", validationEvent);
// All DOM event handling funcitons receive an argument
// that references the event they are responding to.
// We need that reference if we want to cancel the event
function validationEvent(evt) {
// Conditions
if (email.value.trim() !== cemail.value.trim()) {
alert("Your email doesn't match!");
// Cancel the form submit event
evt.preventDefault();
evt.stopPropagation();
return;
}
// You need to have already gotten the "mysqli_num_rows($result)" value
// from your .php file and saved it to a variable that you can then check
// here against "!=0"
if(mysqli_num_rows($result) != 0) {
alert("Username already taken!");
// Cancel the form submit event
evt.preventDefault();
evt.stopPropagation();
} else {
alert("Thank you");
}
}
});

For checking the emails with email & cemail use
email.localeCompare(cemail)
This will check the string comparison betwwen two emails
And for mysqli_num_rows , is not defined any where in javascript, so we will get the undefined error in console, so need to write a different funnction with that name.

First give a name and an action to your form
<form class="form-horizontal" id="myform" action="chkValues.php" method="post" >
....
<div class="form-group">
<div class="col-sm-12">
<input type="email" id="email" placeholder="Email" name="email" class="form-control" required>
</div>
</div>
<div class="form-group">
<div class="col-sm-12">
<input type="email" id="cemail" placeholder=" Re-enter Email" name="cemail" class="form-control" required>
</div>
</div>
....
</form>
Then put this script at the bottom
<script>
$('#myForm').on("sumbit", function(){
// cancel the original sending
event.preventDefault();
$.ajax({
var form = $(this);
var action = form.attr("action"),
method = form.attr("method"),
data = form.serialize();
})
.done: function(data) // is called wehn the call was okay
{
if( data.substr(0, 5) == "Error"){
alert(data); // sent the sting of the "error message" begining with "Error"
}else{
top.location.href = data; // sent the sting of the "success page" when all was okay and data are saved in the database
}
}
.fail(function() {
alert( "Error: Getting data from Server" );
})
});
</script>
in the php file check the values an return an error if something went wrong.
<?php
if(!isset($_POST['email']) || !isset($_POST['cemail'])){
die("Error: Please fill out both email fields.");
if($_POST['email'] != $_POST['cemail'] ){
die("Error: The Email adresses do not match.");
}
here do what you want to do with the data.
when finish just send the new url
echo "success.html";
}
?>

Form Validation with jQuery - Weird Redirect

Alright, so I'm trying to do form validation with jQuery. Not sure why but when you click submit it redirects you to the page you're at already.
The forms action is blank and I included the javascript file in the header.
I will put the code below. Let me know if you see whats wrong. I want it to validate with jQuery then send you to a php file with those values in the method POST.
Register.js:
$(document).ready(function() {
$('button[name=regsubmit]').click(function(){
var fname = $('input[name=regfirstname');
var lname = $('input[name=reglastnaame');
var email = $('input[name=regemail');
var password = $('input[name=regpassword');
var repeatpassword = $('input[name=regrepeatpassword');
var username = $('input[name=regusername');
var atpos = email.indexOf("#");
var dotpos = email.indexOf(".");
if (fname==null || fname=="")
{
alert('First name must be filled out!');
return false;
}
if (lname==null || lname=="")
{
alert('Last name must be filled out!');
return false;
}
if (atpos<1 || dotpos<atpos+2 || dotpos+2>=email.length)
{
alert('Not a valid e-mail address!');
return false;
}
if (username==null || username=="")
{
alert("Username field must be filled out!");

Alright your JS and HTML is a big mess of stuff, so I won't recreate it all, but basics:
Give your form an ID:
<form id="SomeForm" name="register" method="POST">
Then prevent default action, and submit if passes:
// reference the button by the ID you gave it
$('#regsubmit').click(function(e){
// stop original submission
e.preventDefault();
// all your checking stuff here, but if true, then:
document.getElementById('SomeForm').submit();
});
This ensures that you are referencing the button correctly, preventing submission correctly, and submitting only if valid.

prevent default action on submit
$('button[name=regsubmit]').click(function(e)
{
e.preventDefault();
//your code below
}
