How to prevent the click event in JQuery?

There is one toggle switch, When click on a toggle it switches ON and popup with close and Ok button appears.
But if I again click on a toggle then it switches off and toggle disappears.
The actual requirement is, with a every click for which the toggle switches ON and popup appears, the toggle switch should not get switch OFF until user click on close button which is present in popup.

<script>
$(document).ready(function () {
var status = 0;
$(document).on('click', '#isImpliedDelete', function () {
status++;
console.log(status);
var popup = document.getElementById("myPopup");
popup.classList.toggle("show");
if (status % 2 == 0) {
$("#submitBtn").prop('disabled', false);
} else {
$("#submitBtn").prop('disabled', true);
}
});
$("#isImpliedDelete").click(function () {
$("#myPopup").show();
if ($("#submitBtn").prop('disabled', false) == true) {
$("#myPopup").show();
}
});
$("#ok").on('click', function () {
$("#myPopup").hide()
$("#submitBtn").prop('disabled', false);
});
$("#close").on('click', function () {
if ($("#myPopup").show() == true) {
$("#myPopup").hide();
}
$("#isImpliedDelete").click();
$("#submitBtn").prop('disabled', false);
console.log("close");
});
});

In terms of logic, what you want to do is check first if the modal is visible or not. If it isn't, then the switch should launch the modal. If it's visible, then the switch should remain in it's current state (we'll use e.preventDefault(); to do this).
Here is a modified version of your fiddle:
EDIT2: updated fiddle based on new comment:
http://jsfiddle.net/5fb4xc0L/1/
One observation about your code:
I see that you are using the jquery hide function BUT you are also using separate "show" and "hide" classes to visually toggle the visibility of the modal. You cannot use hide() to hide the element then expect that toggling the class .show to bring it back. Here is an explanation

I didn't understand what you actually want but i just solve your toggle problem. have a look
$(document).ready(function(){
$(document).on('click','#isImpliedDelete',function(){
$(this).attr('disabled', true);
$('#myPopup').addClass('show');
})
$(document).on('click','#ok',function(){
$(this).parents('.popup').next('.input-group-prepend').find('input[type="checkbox"]').prop('checked', false);
$('#myPopup').removeClass('show');
$('#isImpliedDelete').removeAttr('disabled')
})
})

Create toggle element without ::before and ::after

How can I create a toggle element without using pseduo ::before and ::after?
I want to create a toggle on an html page but without using the pseudo ::before and ::after.
I am currently using the method from w3Schools given here: https://www.w3schools.com/howto/howto_css_switch.asp
However, I don't want any ::before or ::after psuedo classes. I just want classes by alone, if possible. I tried rewriting my own class for this but didn't seem to work as intended.
/* The switch - the box around the slider */
.switch {
position: relative;
display: inline-block;
width: 60px;
height: 34px;
}
/* Hide default HTML checkbox */
.switch input {
opacity: 0;
width: 0;
height: 0;
}
/* The slider */
.slider {
position: absolute;
cursor: pointer;
top: 0;
left: 0;
right: 0;
bottom: 0;
background-color: #ccc;
-webkit-transition: .4s;
transition: .4s;
}
.slider:before {
position: absolute;
content: "";
height: 26px;
width: 26px;
left: 4px;
bottom: 4px;
background-color: white;
-webkit-transition: .4s;
transition: .4s;
}
input:checked + .slider {
background-color: #2196F3;
}
input:focus + .slider {
box-shadow: 0 0 1px #2196F3;
}
input:checked + .slider:before {
-webkit-transform: translateX(26px);
-ms-transform: translateX(26px);
transform: translateX(26px);
}
/* Rounded sliders */
.slider.round {
border-radius: 34px;
}
.slider.round:before {
border-radius: 50%;
}
I tried making a sliderbefore element myself without the psudeo and it didn't seem to work. (it was missing the small circle inside the toggle)
.sliderbefore {
border-radius: 34px;
position: absolute;
cursor: pointer;
top: 0;
left: 0;
right: 0;
bottom: 0;
background-color: #ccc;
transition: .4s;
box-shadow: 0 0 1px #2196F3;
}

With classList.toggle:
const a= document.getElementsByClassName('a');
const b= document.getElementsByClassName('b');
function changeColor(){
a[0].classList.toggle("d");
b[0].classList.toggle("e");
}
.a{
position: absolute;
border:1px solid red;
width: 500px;
height:300px;
background:green;
}
.b {
left:51px;
position: absolute;
top:2px;
float: right;
border-radius:50%;
width: 35px;
height:35px;
background: white;
transition: all 0.1s;
}
.c {
position: absolute;
top:40px;
left:130px;
border-radius:20px;
width: 90px;
height:40px;
background: #ced0d4;
}
.d{
background: blue;
}
.e{
left:4px;
}
<div class="a">
<div class="c" onclick="changeColor()">
<div class="b"></div>
</div>
</div>

I was able to create a toggle element by using javascript and html only instead of psuedo :before and :after
<html><head></head>
<script type="text/javascript">
function toggle(button) {
if (button.value == "OFF") {
button.value = "ON";
} else {
button.value = "OFF";
}
}
</script>
<body>
<form action="">
<input type="button" id="1" value="ON" style="color:blue"
onclick="toggle(this);">
</form></body></html>
The element is an input which has a Value of ON.
The Toggle function will switch the toggler on and off when clicked.

converting HTML button to CSS Switch to function with Javascript

I have the following code that works very nice and sweetly
HTML
<button id="changeColor">changeColor</button>
-Javascript
<script>
document.getElementById("changeColor").addEventListener('click', function(){
document.getElementsByClassName("Bkground")[0].style.backgroundColor = document.getElementById("changeColor").check ? "white" : "black";
});
</script>
- I would like to use the CSS Switch below instead of the HTML button to switch between white and black
<style>
.switch {
position: relative;
display: inline-block;
width: 60px;
height: 34px;
}
.switch input {
opacity: 0;
width: 0;
height: 0;
}
.slider {
position: absolute;
cursor: pointer;
top: 0;
left: 0;
right: 0;
bottom: 0;
background-color: #ccc;
-webkit-transition: .4s;
transition: .4s;
}
.slider:before {
position: absolute;
content: "";
height: 26px;
width: 26px;
left: 4px;
bottom: 4px;
background-color: white;
-webkit-transition: .4s;
transition: .4s;
}
input:checked + .slider {
background-color: #2196F3;
}
input:focus + .slider {
box-shadow: 0 0 1px #2196F3;
}
input:checked + .slider:before {
-webkit-transform: translateX(26px);
-ms-transform: translateX(26px);
transform: translateX(26px);
}
/* Rounded sliders */
.slider.round {
border-radius: 34px;
}
.slider.round:before {
border-radius: 50%;
}
</style>
<label class="switch">
<input type="checkbox">
<span class="slider round"></span>
</label>
-please note that my class is "Bkground" that's why I had document.getElementsByClassName(Bkground)
I want to fix two things
I would like to use the CSS Switch instead of the HTML button to switch between white and black
I want to be able to switch between two colors (black and white) when the button being clicked
like
<script>
if ( document.getElementById("changeColor").addEventListener('click', function(){
document.getElementsByClassName("mainWrapper fullWidth")[0].style.backgroundColor = document.getElementById("changeColor").changeColor ? "white" : "black");
else ( document.getElementById("changeColor").addEventListener('click', function(){
document.getElementsByClassName("mainWrapper fullWidth")[0].style.backgroundColor = document.getElementById("changeColor").changeColor ? "black" : "white");)
});
</script>

You need to simple change (add and remove a CSS class), and change UI based on it. This will be easiest.
$(document).ready(function(){
$("#changeColor").click(function(){
$("p").toggleClass("changed");
$("#changeColor").toggleClass("changed");
$("body").toggleClass("changed");
});
});
body {background: pink;}
body.changed {background:gray;}
button {background: yellow;}
button.changed {background: green;}
p {background: orange;}
p.changed {background: blue;}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
<button id="changeColor">Toggle</button>

Disabling page reloading while using form

I want to use a form with a checkbox as follow :
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
<style>
.switch {
position: relative;
display: inline-block;
width: 60px;
height: 34px;
}
.switch input {
opacity: 0;
width: 0;
height: 0;
}
.slider {
position: absolute;
cursor: pointer;
top: 0;
left: 0;
right: 0;
bottom: 0;
background-color: #ccc;
-webkit-transition: .4s;
transition: .4s;
}

content: "";

}
input:checked + .slider:before {
-webkit-transform: translateX(26px);

transform: translateX(26px);
}
/* Rounded sliders */
.slider.round {
border-radius: 34px;
}

border-radius: 50%;
}
</style>
</head>
<body>
<h2>Toggle Switch</h2>
<label class="switch">
<form id= "test" method="POST" action="test">
})
<input type="checkbox"
name='switch'
onClick="document.forms['test'].submit();"
>
<span class="slider round"></span>
</label>
</form>
</body>
So far I've been able to do it for submit button using the following script:
....
// wait for the DOM to be loaded
$(document).ready(function() {
// bind 'myForm' and provide a simple callback function
$('#test').ajaxForm(function() {
alert("");
});
....
But this isn't working apparently for checkbox. Any idea how may I do it!
thanks in advance !

This will be done as below:
$(document).ready(function() {
$('#test').on('submit', function(e) {
e.preventDefault();
alert("");
});

You need to use the "onchange" event instead of "onclick" and check the value. If it is checked, submit the form. And remove the event after, otherwise the form can be submited multiple times when toggling.
But it sounds simpler to use a button and style it like a checkbox with an image.
<button type="submit"><img src="/img/checkbox.png" alt="Checkbox" /></button>
You need no additional javascript for this and it is trivial to make the on/off state with CSS.
Also obviously use your ajaxForm function to avoid a page reload. Otherwise the "on" state will never be visible.

Try using the preventDefault() function, along the lines:
....
// wait for the DOM to be loaded
$(document).ready(function() {
const form = document.getElementById('test');
form.onsubmit = function (event) {
alert("");
// For this example, don't actually submit the form
event.preventDefault();
}
....

Use e.preventDefault(); in on click event
Codepen example
How preventDefault() works?
Also there are some mistakes in HTML structure
you opened label tag before the form so you should close it after
the form.
there are additional bracket and parenthesis

$(document).ready(function() {
$('#togglSwitch').change(function() {
alert("Handler for .submit() called.");
event.preventDefault();
$(this).closest("form").submit();
});
});
.switch {
position: relative;

}

Note:- You need to add event.preventDefault and need to add submit event on change is the solution for your problem

Call function on onclick of CheckBox

Here write the code of Ajax to submit the form.

How to make a switch change between two sets of text?

I'm trying to make a switch bar change between two sets of text. I've got the switch and the slider working but can't figure out how to attach the funciton to the slider.
I've made testing environment using W3School:
https://www.w3schools.com/code/tryit.asp?filename=FVEFVIB1J6D2
The switch code had the formatting correct but its not taking the formatting for the graphic.
function myFunction() {
var x = document.getElementById("myDIV");
if (x.innerHTML === "Longer text") {
x.innerHTML = "Shorter text";
} else {
x.innerHTML = "Longer text";
}
}
.switch {
position: relative;
display: inline-block;
width: 90px;
height: 34px;
}
.switch input {display:none;}
.slider {
position: absolute;
cursor: pointer;
top: 0;
left: 0;
right: 0;
bottom: 0;
background-color: #009bff;
-webkit-transition: .4s;
transition: .4s;
}
.slider:before {
position: absolute;
content: "";
height: 26px;
width: 26px;
left: 4px;
bottom: 4px;
background-color: white;
-webkit-transition: .4s;
transition: .4s;
}
input:checked + .slider {
background-color: #2ab934;
}
input:focus + .slider {
box-shadow: 0 0 1px #2196F3;
}
input:checked + .slider:before {
-webkit-transform: translateX(55px);
-ms-transform: translateX(55px);
transform: translateX(55px);
}
/* Rounded sliders */
.slider.round {
border-radius: 34px;
}
.slider.round:before {
border-radius: 50%;
}
<p>
<switch onclick="myFunction()">Choose your lenght </switch>
</p>
<label class="switch">
<input type="checkbox">
<span class="slider round"></span>
</label>
<div id="myDIV">Longer Story</div>

You just need to attach a listener to the input changes
HTMLInputElementObject.addEventListener('input', function (evt) {
myFunction();
});
assuming "input" as HTMLInputElementObject:
function myFunction() {
var x = document.getElementById("myDIV");
if (x.innerHTML === "Longer text") {
x.innerHTML = "Shorter text";
} else {
x.innerHTML = "Longer text";
}
}
document.getElementById("mySlider").addEventListener('input', function (evt) {
myFunction();
});
.switch {
position: relative;
display: inline-block;
width: 90px;
height: 34px;
}
.switch input {display:none;}
.slider {
position: absolute;
cursor: pointer;
top: 0;
left: 0;
right: 0;
bottom: 0;
background-color: #009bff;
-webkit-transition: .4s;
transition: .4s;
}
.slider:before {
position: absolute;
content: "";
height: 26px;
width: 26px;
left: 4px;
bottom: 4px;
background-color: white;
-webkit-transition: .4s;
transition: .4s;
}
input:checked + .slider {
background-color: #2ab934;
}
input:focus + .slider {
box-shadow: 0 0 1px #2196F3;
}
input:checked + .slider:before {
-webkit-transform: translateX(55px);
-ms-transform: translateX(55px);
transform: translateX(55px);
}
/* Rounded sliders */
.slider.round {
border-radius: 34px;
}
.slider.round:before {
border-radius: 50%;}
<label class="switch">
<input type="checkbox" id="mySlider">
<span class="slider round"></span>
</label>
<div id="myDIV">Longer text</div>

Your're almost finished. All you have to do is add an onClick callback to the span with the class slider round like this:
<label class="switch">
<input type="checkbox">
<span class="slider round" onclick='myFunction()'></span>
</label>

Your onclick needs to be on the input element or span element like so
<label class="switch">
<input type="checkbox" onclick="myFunction()">
<span class="slider round"></span>
</label>
I also cleaned up your code for you since your style tags was inside the body and you had extra body tags and your elements were outside the html tag for whatever reason.
https://www.w3schools.com/code/tryit.asp?filename=FVEGHO8VCQJA

You have to include the onclick to the checkbox with this as parameter.
<input type="checkbox" onclick='myFunction(this)'>
this is necessary to check if the checkbox is checked or not. If it is true than use the second text, otherwise use the first text.
Example for multiple usage
var text = {
1: ["Longer text", "Shorter text"],
2: ["Another longer text", "Another shorter text"]
// Add more
}
var output1 = document.getElementById("output");
var output2 = document.getElementById("output2");
function switchText(that, output, text) {
switch (that.checked) {
case true:
output.innerHTML = text[1];
break;
default:
output.innerHTML = text[0];
}
}
function switchFirstText(that) {
switchText(that, output1, text[1]);
}
function switchSecondText(that) {
switchText(that, output2, text[2]);
}
.switch {
position: relative;
display: inline-block;
width: 90px;
height: 34px;
}
.switch input {
display: none;
}
