HTML 5 Validation Customization

I would like to have a form that:
Display validation messages in a custom format instead of the default style.
Display all invalid field bubbles at once instead of one at a time.
Right now, I am stuck with the boring browser-specific message appearance and I don't see the next error until I correct the last one. This is a really bad user experience, so looking for a few pointers on how to address this.
This is my current JavaScript code:
const contactUsForm = document.querySelector('#Form');
if (contactUsForm) {
function Validate() {
validatedFields = contactUsForm.querySelectorAll('[data-validation-required],[data-validation-format]');
validatedFields.forEach(field => {
/* RegEx patterns */
const emailPattern = /^((([a-z]|\d|[!#\$%&'\*\+\-\/=\?\^_`{\|}~]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])+(\.([a-z]|\d|[!#\$%&'\*\+\-\/=\?\^_`{\|}~]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])+)*)|((\x22)((((\x20|\x09)*(\x0d\x0a))?(\x20|\x09)+)?(([\x01-\x08\x0b\x0c\x0e-\x1f\x7f]|\x21|[\x23-\x5b]|[\x5d-\x7e]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(\\([\x01-\x09\x0b\x0c\x0d-\x7f]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]))))*(((\x20|\x09)*(\x0d\x0a))?(\x20|\x09)+)?(\x22)))#((([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])*([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])))\.)+(([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])*([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])))$/i;
if (field.getAttribute('type') === 'email')
{
field.setAttribute('pattern', emailPattern);
}
if (field.validity.valueMissing) {
field.setCustomValidity(field.dataset.validationRequired);
}
else if (field.validity.patternMismatch) {
field.setCustomValidity(field.dataset.validationFormat);
}
else {
field.setCustomValidity('');
}
field.reportValidity();
contactUsForm.checkValidity();
/* Recheck on field value change */
field.addEventListener('change', function() {
field.setCustomValidity('');
Validate();
});
});
}
Validate();
contactUsForm.addEventListener('submit', function(e) {
e.preventDefault;
if (e.checkValidity() == false) {
return false;
}
else {
// form.submit()
}
});
}

Styling validation bubbles/tooltips used to be feature but only exclusive to Chrome, however it got removed.
More information about it here:
How do you style the HTML5 form validation messages?
However, you can create your own tooltips or bubbles to display validation messages. With use of a div container and a span and a little bit of CSS, you can create a bubble with almost any kind of look you can image.
.ttCont {
position: relative;
display: inline-block;
}
.ttCont .ttText {
display: inline-block;
visibility: hidden;
min-width: 200px;
background-color: darkblue;
color: #fff;
text-align: center;
border-radius: 6px;
padding: 5px;
opacity: 0;
transition: opacity 0.5s;
/* Place bubble to the right of container */
position: absolute;
z-index: 1;
top: 5px;
left: 105%;
}
.ttCont .ttText::after {
content: " ";
position: absolute;
top: 50%;
right: 100%; /* To the left of the bubble */
margin-top: -5px;
border-width: 5px;
border-style: solid;
border-color: transparent darkblue transparent transparent;
}
.ttCont .ttText.active{
visibility: visible;
opacity: 1;
}
Use of custom bubbles now means that you might need to use less of the ValidityState API, however you can still validate your fields using the same approach. Instead of using field.reportValidity(), you can create a custom function that shows a bubble whenever each field validates
function customReportValidatity(elem, type) {
let msg = "";
///check if validity is based on required or mismatch///
switch (type) {
case 'required':
msg = $(elem).attr('data-validation-required');
///without jQuery
// msg = elem.dataset.validationRequired;
break;
case 'format':
msg = $(elem).attr('data-validation-format');
///without jQuery
// msg = elem.dataset.validationFormat;
break;
default:
break;
}
///make popup appear///
let ttText = $(elem).parent().children('.ttText');
$(ttText).text(msg);
$(ttText).addClass('active');
///without jQuery
// let ttText = elem.parentElement.querySelector('.ttText');
// ttText.innerText = msg;
// ttText.classList.add('active');
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.0/jquery.min.js"></script>
With that styling and custom function, you can apply it to your existing code for any form you are willing to apply to. In this case, I made an example form that takes in a name and email that are required, while the description is not required.
const contactUsForm = document.querySelector('#Form');
const submitBtn = document.querySelector('#submitBtn');
if (contactUsForm) {
function customReportValidatity(elem, type) {
let msg = "";
///check if validity is based on required or mismatch///
switch (type) {
case 'required':
msg = $(elem).attr('data-validation-required');
///without jQuery
// msg = elem.dataset.validationRequired;
break;
case 'format':
msg = $(elem).attr('data-validation-format');
///without jQuery
// msg = elem.dataset.validationFormat;
break;
default:
break;
}
///make popup appear///
let ttText = $(elem).parent().children('.ttText');
$(ttText).text(msg);
$(ttText).addClass('active');
///without jQuery
// let ttText = elem.parentElement.querySelector('.ttText');
// ttText.innerText = msg;
// ttText.classList.add('active');
}
function Validate() {
let isValid = true;
/* RegEx patterns */
const emailPattern = /^((([a-z]|\d|[!#\$%&'\*\+\-\/=\?\^_`{\|}~]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])+(\.([a-z]|\d|[!#\$%&'\*\+\-\/=\?\^_`{\|}~]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])+)*)|((\x22)((((\x20|\x09)*(\x0d\x0a))?(\x20|\x09)+)?(([\x01-\x08\x0b\x0c\x0e-\x1f\x7f]|\x21|[\x23-\x5b]|[\x5d-\x7e]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(\\([\x01-\x09\x0b\x0c\x0d-\x7f]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]))))*(((\x20|\x09)*(\x0d\x0a))?(\x20|\x09)+)?(\x22)))#((([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])*([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])))\.)+(([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])*([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])))$/i;

Function to count number of line breaks acts differently on $(window).on('resize') and $(document).ready

I have a function which counts the number of line breaks in a div, depending on the width of the window. While the functions works fine when placed in the $(window).on('resize') function, it does not work when put in $(document).ready() function. I want it to work right on page load, and also window resize, how do I support both?
JSFiddle
Javascript/jQuery:
// functions called in both document.ready() and window.resize
$(document).ready(function(){
var lineCount = getLineCount();
postItems(lineCount);
$('.answer').text("Ready");
});
$(window).on('resize', function(){
var lineCount = getLineCount();
postItems(lineCount);
$('.answer').text("Number of lines: " + lineCount);
});
// calculates the amount of lines required to hold the items
function getLineCount() {
var lineWidth = $('.line').width();
var itemWidthSum = 0;
var lineCount=1;
$('.item').each(function(index, element) {
if((lineWidth - itemWidthSum) > ($(element).outerWidth())) {
itemWidthSum = itemWidthSum + $(element).outerWidth();
} else {
lineCount++;
itemWidthSum = $(element).outerWidth();
}
});
return lineCount;
}
// overlays rows for the amount of linebreaks
function postItems(lineCount){
var container = $('<div />');;
for(var i = 1; i <= lineCount; i++) {
container.append('<div class="line">' + i + '</div>');
}
$('.line-wrap').html(container);
}
You'll see at the start of the page, it incorrectly shows 17 lines, and then once you resize it will show the correct amount.

The issue lies in the first line of getLineCount(). Originally you had
var lineWidth = $('.line').width();
but no elements with the class "line" exist yet on your page (since they get added in your postItems() method. I changed it to
var lineWidth = $(".container").width();
instead, and now your code should be working. Snippet posted below:
$(document).ready(function(){
var lineCount = getLineCount();
postItems(lineCount);
$('.answer').text("Ready");
});
$(window).on('resize', function(){
var lineCount = getLineCount();
postItems(lineCount);
$('.answer').text("Number of lines: " + lineCount);
});
// calculates the amount of lines required to hold the items
function getLineCount() {
var lineWidth = $('.container').width();
var itemWidthSum = 0;
var lineCount=1;
$('.item').each(function(index, element) {
if((lineWidth - itemWidthSum) > ($(element).outerWidth())) {
itemWidthSum = itemWidthSum + $(element).outerWidth();
} else {
lineCount++;
itemWidthSum = $(element).outerWidth();
}
});
return lineCount;
}
// overlays rows for the amount of linebreaks
function postItems(lineCount){
var container = $('<div />');;
for(var i = 1; i <= lineCount; i++) {
container.append('<div class="line">' + i + '</div>');
}
$('.line-wrap').html(container);
}

Jquery functions continue to apply even the CSS is changed. How do I stop this?

The fiddle first.
I have nameCards which expand and contract when clicked by adding/removing classes. Additionally, they move to different sections in the page when buttons are clicked (again by adding/removing classes). The problem: Despite them no longer having the classes needed to trigger the functions, the function still applies to them.
In the code, they move from .unmatched to .matched, so the function selector $('.matched.nameCard') should no longer work, but it does, as shown by the fact that the alert from the .click() still shows after it got moved.
I've tried event.stopProgation() basically everywhere in the functions, tried using a local variable instead of the global variable currentCard, and have double checked that the classes are changing by inspecting using .html. By my reasoning, the second they change from .unmatched to .matched the original function should stop working. Can anybody help me figure out why it's not?
Final note, the formatting got screwed up a little in the switch to fiddle, please forgive the funkyness. I tried to get rid of as much extra stuff as possible.
Edit: Changed from #matched in my question to .matched

cardContents.hide();
} else {
cardContents.show();
}
});
//stops card from closing if you click on buttons/input and carries out button events
currentCard.on("click", ".btn", function(event) {
$("#unpairButton").text("Are you sure you want to unpair " + memberName + " and " + pnmName + "?");
});
currentCard.on("click", ".ansField", function(event) {
event.stopPropagation();
});
//.unbind() is the best thing to happen to me
//Unmatched to Matched
$('#pairModal #pairButton').unbind('click').on("click", function(event) {
var pnmLastName = $("#lastName").val();
var pnmFirstName = $('#firstName').val();
currentCard.removeClass('unmatched');
currentCard.addClass('matched');
currentCard.children(".nameCardContents").hide();
var addPNM = $("<div class='matchedNameCardContents'><p class='pnmName'>" + pnmFirstName + " " + pnmLastName + "</p><button type='button' class='btn btn-default' data-toggle='modal' data-target='#unpairModal'>Unpair</button></div>");
currentCard.append("<div><p class='pnmName'>" + pnmFirstName + " " + pnmLastName + "</p><button type='button' class='btn btn-default' data-toggle='modal' data-target='#unpairModal'>Unpair</button></div>");
currentCard.prependTo("#matched");
});
});
});

I figured it out! I looked into event delegation based on the comments and changed everything to take that into account. Here's a preview of what my new functions look like:
$(document).ready(function(){
$('#unmatched').off().on("mouseover", ".unmatched.nameCard", function() {
var currentCard = $(this);
var memberName = $(this).children(".memberName").text();
currentCard.off('click').on("click", function() {
//switches between "active" and "inactive (preClick)" card
$("#unmatched .nameCard").addClass('nameCard preClick');
currentCard.toggleClass('nameCard');
currentCard.toggleClass('nameCard preClick');
var cardContents = $('.nameCardContents');
cardContents.appendTo(currentCard);
if (currentCard.is(".nameCard.preClick") ) {
cardContents.hide();
} else {
cardContents.show();
}
});
//stops card from closing if you click on buttons/input and carries out button events
currentCard.off('click', ".btn").on("click", ".btn", function(event) {
var pnmLastName = $("#lastName").val();
var pnmFirstName = $('#firstName').val();
$("#pairDialog").text("Are you sure you want to pair " + memberName + " with " + pnmFirstName + " " + pnmLastName + "?");
$("#removeMember").text("How long do you want to remove " + memberName + " from recruitment?");
});
});
});

display a div below a selected input field? No JQuery

how to display a div everytime a user focus on a input field. there is already a div and it is hidden. the position of the div will change depending on the position of the selected field and it will be display below
this is my code
formFieldListWrapper.style.top = ((((formSelectedFieldInput.offsetTop > (formWrapper.offsetHeight/2))?((formSelectedFieldInput.offsetTop-(formWrapper.offsetHeight/2))-(formSelectedFieldInput.offsetHeight+formWrapper.offsetHeight*0.02)):(formSelectedFieldInput.offsetTop))/formWrapper.offsetHeight)*100) + "%";
formFieldListWrapper.style.left = ((formSelectedFieldInput.offsetLeft/formWrapper.offsetWidth)*100) + "%";

Why use javascript? This could be chieved by using CSS only
HTML
<div class="holder">
<input type="text" />
<div class="dropdown">
<p>Testing</p>
<p>Css ONLY</p>
<p>Dropdown</p>
</div>
</div>
CSS
.holder {
position: relative;
}
.dropdown {
position: absolute;
border: 1px solid red;
display: none;
}
input:focus + .dropdown {
display: block;
}
UPDATE
little bit misred the question, if You need to position div dynamically like in this fiddle, You cloud use:
HTML
<div class="holder">
<input type="text" />
</div>
<div class="holder" style="margin-top: 30px;">
<input type="text" />
</div>
<div class="dropdown">
<p>Testing</p>
<p>Css ONLY</p>
<p>Dropdown</p>
</div>
CSS
.holder {
position: relative;
}
.dropdown {
position: absolute;
border: 1px solid red;
display: none;
z-index: 1;
background: white;
}
input:focus + .dropdown {
display: block;
}
Javascript to position dropdown div
var inputs = document.querySelectorAll('input');
for (var i = 0; i < inputs.length; i++) {
inputs[i].addEventListener('focus', function(){
this.parentNode.appendChild(document.querySelector('.dropdown'));
});
}

Try the following:
formSelectedFieldInput.addEventListener("focus", setDivToInput, false);
function setDivToInput(e)
{
var inputElement = e.target; //e.target refers to the element that fired the event.
formFieldListWrapper.style.top = inputElement.offsetTop + formFieldListWrapper.offsetHeight + "px";
formFieldListWrapper.style.left= inputElement.offsetLeft + "px";
formFieldListWrapper.style.display = "block";
}
The first line adds a focus event to the input. This sets the div to the input based upon it's position on the page. This is very basic and doesn't behave well when the div runs of the screen. You need to add logic for that.
Now for multiple inputs in a form
var nodes = form.querySelectorAll("input"); //replace with your form element
for (var i = 0; i < nodes.length; ++i)
{
nodes[i].addEventListener("focus", setDivToInput, false);
}
function setDivToInput(e)
{
var node = e.target;
formFieldListWrapper.style.top = node.offsetTop + formFieldListWrapper.offsetHeight + "px";
formFieldListWrapper.style.left= node.offsetLeft + "px";
formFieldListWrapper.style.display = "block";
}
This code sets the focus event to all inputs in the form.

Making a javascript popup draggable

I am creating a JavaScript popup. The code is as below.
The HTML:
<div id="ac-wrapper" style='display:none' onClick="hideNow(event)">
<div id="popup">
<center>
<h2>Popup Content Here</h2>
<input type="submit" name="submit" value="Submit" onClick="PopUp('hide')" />
</center>
</div>
</div>
The CSS:
#ac-wrapper {
position: fixed;
top: 0;
left: 0;
width: 100%;
height: 100%;
background: url("images/pop-bg.png") repeat top left transparent;
z-index: 1001;
}
#popup {
background: none repeat scroll 0 0 #FFFFFF;
border-radius: 18px;
-moz-border-radius: 18px;
-webkit-border-radius: 18px;
height: 361px;
margin: 5% auto;
position: relative;
width: 597px;
}
The Script:
function PopUp(hideOrshow) {
if (hideOrshow == 'hide') document.getElementById('ac-wrapper').style.display = "none";
else document.getElementById('ac-wrapper').removeAttribute('style');
}
window.onload = function () {
setTimeout(function () {
PopUp('show');
}, 0);
}
function hideNow(e) {
if (e.target.id == 'ac-wrapper') document.getElementById('ac-wrapper').style.display = 'none';
}
The jsFiddle Link:
http://jsfiddle.net/K9qL4/2/
The Issue:
The above script works fine, but I need to make the popUp draggable.

Here's some code that will do what you want. It relies only on an object called drag to store all its values, but you can easily alter that. The example relies on there being a div with the id of mydiv (a document.write() is used in this instance to supply that) that has a position attribute of absolute or fixed. You can see it in action at Jamie
document.write("<" + "div id='mydiv' style='background:blue; width:100px;"
"height:100px; position:fixed;'>" + "<" + "/div>");
var drag = new Object();
drag.obj = document.getElementById('mydiv');
drag.obj.addEventListener('mousedown', function(e)
{
drag.top = parseInt(drag.obj.offsetTop);
drag.left = parseInt(drag.obj.offsetLeft);
drag.oldx = drag.x;
drag.oldy = drag.y;
drag.drag = true;
});
window.addEventListener('mouseup', function()
{
drag.drag = false;
});
window.addEventListener('mousemove', function(e)
{
drag.x = e.clientX;
drag.y = e.clientY;
var diffw = drag.x - drag.oldx;
var diffh = drag.y - drag.oldy;
if (drag.drag)
{
drag.obj.style.left = drag.left + diffw + 'px';
drag.obj.style.top = drag.top + diffh + 'px';
e.preventDefault();
}
});

Use the
.draggable();
jquery function, here is your updated fiddle:
