How to loads the page preloader when user click on nav item - javascript

In my web project, I have used a preloader to load when a page loads.
But I want to load it whenever the user clicks the nav item, if the item clicks show the preloader, and then when the result loads, hide the preloader.
Currently, the preloader works when the nav item clicks and when the requested page started to load.
I would like to know how to load it when as soon as the nav item is clicked.
This is my current code.
<style>
.loader-bg {
position: fixed;
z-index: 999999;
background: #fff;
width: 100%;
height: 100%;
}
.loader {
border: 0 solid transparent;
border-radius: 50%;
width: 150px;
height: 150px;
position: absolute;
top: calc(50vh - 75px);
left: calc(50vw - 75px);
}
.loader:before, .loader:after {
content: '';
border: 1em solid #ff5733;
border-radius: 50%;
width: inherit;
height: inherit;
position: absolute;
top: 0;
left: 0;
animation: loader 2s liner infinite;
opacity: 0;
}
.loader:before {
animation-delay: .5s;
}
#keyframes loader{
0%{
transform:scale(0);
opacity:0;
}
50%{
opacity:1;
}
100%{
transform:scale(1);
opacity:0;
}
}
</style>
<div class="loader-bg">
<div class="loader" id="spinner">
<img src="~/Th/01.png" class="mr-2" alt="logo" width="100px" height="auto" class="center" />
<i class="spinner-border text-secondary"></i>
<label> Please wait...</label>
</div>
</div>
<script>
setTimeout(function () {
$('.loader-bg').fadeToggle();
},
10);
</script>

Why isn't my black overlay appearing when button is clicked?

I am trying to create a pop-up window myself. I want my pop-up box to appear when the button is pressed and everything below to get darkened. However, when I press my button whole page hangs and no popup appears also.
If I remove the div which turns everything background black, my popup is working fine.
Here is my html code which has script tags inside
let visible = false;
$('#showBox').on('click', function(params) {
if (visible) {
$('.box').removeClass('boxVisible');
$('.blackenBackground').removeClass('boxVisible');
visible = false;
} else {
$('.box').addClass('boxVisible');
$('.blackenBackground').addClass('boxVisible');
visible = true;
}
})
.box {
background: pink;
height: 500px;
width: 500px;
position: absolute;
top: 50%;
left: 50%;
z-index: 3;
transform: translate(-50%, -50%);
border-radius: 1%;
opacity: 0;
transition: 0.4s;
transition-timing-function: ease-out;
}
.boxVisible {
opacity: 1;
}
.blackenBackground {
position: fixed;
top: 0;
left: 0;
height: 100vh;
width: 100vw;
background: black;
opacity: 0;
z-index: 2;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="box"></div>
<p>Some lorem text.....
</p>
<button id="showBox">Show Box</button>
<!-- When I remove this popup box works perfectly but background isn't darkening and my page hangs -->
<div class="blackenBackground"></div>

Your fixed position div is blocking mouse events. The opacity is 0 but the box is still technically visible, which catches the click and prevents the button from getting clicked.
Just make sure the box is completely hidden and it should work.
let visible = false;
$('#showBox').on('click', function (params) {
if(visible){
$('.box').removeClass('boxVisible');
$('.blackenBackground').removeClass('boxVisible');
visible = false;
}else{
$('.box').addClass('boxVisible');
$('.blackenBackground').addClass('boxVisible');
visible = true;
}
})
.box{
background: pink;
height: 500px;
width: 500px;
position: absolute;
top: 50%;
left: 50%;
z-index: 3;
transform: translate(-50%, -50%);
border-radius: 1%;
opacity: 0;
transition: 0.4s;
transition-timing-function: ease-out;
}
.boxVisible{
opacity: 1;
display: block;
}
.blackenBackground{
position: fixed;
top: 0;
left: 0;
height: 100vh;
width: 100vw;
background: black;
opacity: 0;
display: none;
z-index: 2;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="box"></div>
<p>Some lorem text.....</p>
<button id="showBox">Show Box</button>
<div class="blackenBackground"></div>

Did you want something like this? I added an id element to the div and changed you addclass call in your Jquery to document.getElementById('dimmer').style.display= 'none / block' in your if-else statements and changed the .css class to
.blackenBackground{
pointer-events: none;
background:#000;
opacity:0.5;
position:fixed;
top:0;
left:0;
width:100%;
height:100%;
display:none;
}

only show modal scroll when a modal is open

Hi can someone tell me why my solution doesn't work, I would like to hide the scroll of my page when a modals is opened.
and allow the scroll on my modal too.
By the same time if a slide up & down effect could be added it will be awesome.
I used javascript but it doesn't work for me now:
$(function(){
$('.modal').click(function() {
$('body').css({'overflow': 'hidden'});
});
$('.close').click(function() {
$('body').css({'overflow': 'scroll'});
});
});
here is my code:
<a class="modal" href="#openModal1">Box 1</a>
<div id="openModal1" class="modalDialog">
x
<div class="middle">
Modal Box 1
This is a sample modal box that can be created using the powers of CSS3. You could do a lot of things here like have a pop-up ad that shows when your website loads, or create a login/register form for users.
</div>
</div>
<a class="modal" href="#openModal2">Box 2</a>
<div id="openModal2" class="modalDialog">

You are trying to use jQuery, but you never included it. Check out the code below. My approach is a little different from yours. I add and remove class instead of changing css property.
$(function(){
$('.modal').click(function() {
$('body').addClass('scroll');
});
$('.close').click(function() {
$('body').removeClass('scroll');
});
});
.scroll {
overflow: hidden;

CSS making a :active toggled

i am trying to create a web presentation and wanted to a add a little Animation of 2 Halfes which moves up and down on a Click (which works so far) but i also want them to stay there after the click.
standard looking version http://img5.fotos-hochladen.net/uploads/3ozt9kfyr08.jpg
0.75 seconds after the click on the logo in the middle http://img5.fotos-hochladen.net/uploads/2lpdyoktws6.jpg
after the animation http://img5.fotos-hochladen.net/uploads/18cd9xfjg21.jpg
This is my Code for that: HTML
<body>
<a href="#" id="btn_logo" onclick="return false"> <div id="animation">
<div id="logo"> </div>
<div id="up"> </div>
<div id="down"> </div>
</div></a>
and then made the animation with:
#btn_logo:active #up
and
#btn_logo:active #down
How could i make the animation toggled after it ended?

What you should do is have it animate on a CSS class, and then simply add or remove a CSS class on click.
Like so: https://jsfiddle.net/8troo8bw/1/
(or so with your exact html): https://jsfiddle.net/8troo8bw/2/
The key here being the animation:
#up, #down {
background: #000;
position:absolute;
right:0;
left:0;
width:100%;
height:25px;
transition: top 0.25s;
}
#up.moveUp {
top: 25px;
}
#down.moveDown {
top: 100px;
}
And the relevent JS to add the class:
$('#click').on('click', function(){
$('#up').addClass('moveUp');
$('#down').addClass('moveDown');
});

Do something like this:
$(document).ready(function(){
$('#animation').on('click', function() {
$('.up,.down').addClass('animated');
});
});
#animation {
position: absolute;
top: 0;
right: 0;
bottom: 0;
left: 0;
background: yellow;
}
.logo {
position: relative;
top: 50%;
transform: translateY(-50%);
height: 50px;
width: 50px;
background: red;
border-radius: 50%;
margin: 0 auto;
}
.up {
position: absolute;
top: 0;
right: 0;
bottom: 50%;
left: 0;
background: green;
}
.down {
position: absolute;
top: 50%;
right: 0;
bottom: 0;
left: 0;
background: blue;
}
.up.animated {
bottom: 100%;
top: -50%;
transition: all 1s linear;
}
.down.animated {
top: 100%;
bottom: -50%;
transition: all 1s linear;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div id="animation">
<div class="up"> </div>
<div class="down"> </div>
<div class="logo"> </div>

making a toggle button to change panels

I have two panels at the top of my application and one button at the button. By default only panel one must be visible, but by clicking on the button panel one fades away, and panel two fades in. I created the layout, but I do not know how to achieve it.
$(".panel2").hide();
$(document).ready(function() {
$(".grid-button").on("click", function() {
$(".grid").toggleClass("open close");
});
});
div.app {
margin:50px auto;
width: 400px;
height: 400px;
border-radius:10px;
overflow: hidden;
position: relative;
}
div.app > .blur {
width: 100%;
height: 100%;
background: url(http://goo.gl/0VTd9W);
-webkit-filter: blur(5px);
}
div.mainSection, div.dashboard{
position: absolute;
left: 0px;
text-align:center;
color:#fff;
font-size:20px;
}
div.mainSection{
width:100%;
height:85%;
background:rgba(0,0,0,0.5);
top:0;
}
div.dashboard{
width:100%;
height:15%;
background:rgba(255,0,0,0.5);
bottom:0;
}
div.mainSection > .panel1,
div.mainSection > .panel2 {
width: 100%;
Height: 100%;
Background: rgba(0, 0, 0, 0.5);
position: absolute;
left: 0px;
top: 0px;
}
.grid-button {
background: none;
border: none;
padding: 3px;
width: 100%;
}
.grid {
display: inline-block;
height: 4px;
position: relative;
width: 32px;
transition: all 0.3s ease-in-out;
}
.grid:after, .grid:before {
content: '';
position: absolute;
background-color: #FFF;
display: inline-block;
height: 4px;
left: 0;
width: 32px;
transition: all 0.3s ease-in-out;
}
.grid.open {
background-color: #FFF;
}
.grid.open:after {
top: 10px;
}
.grid.open:before {
top: -10px;
}
.grid.close {
background-color: transparent;
transform: scale(0.9);
}
.grid.close:after, .grid.close:before {
top: 0;
transform-origin: 50% 50%;
}
.grid.close:before {
transform: rotate(135deg);
}
.grid.close:after {
transform: rotate(45deg);
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="app">
<div class="blur"></div>
<div class="mainSection">
<div class="panel1">Panel1</div>
<div class="panel2">Panel2</div>
</div>
<div class="dashboard">
<div class="grid-button">
<span class="grid open"></span>
</div>
</div>
</div>
First of all since I did $('.panel2').hide();, in page load first it loads the panel then hides it. How can I make it invisible from the beginning?
Secondly how can I make the panel2 visible only by pressing the button?
And finally is there anyway to add some transitions effects for changing panels?

You may try:
$(".grid-button").on("click", function() {
var visibleObj = $('.mainSection div:visible');
var inVisibleObj = $('.mainSection div:hidden');
visibleObj.fadeOut(500, function() {
inVisibleObj.fadeIn(500);
});
});
While for the visibility you need:
<div class="panel2" style="display: none;">Panel2</div&gt
The running snippet:
$(function () {
$(".grid-button").on("click", function() {
var visibleObj = $('.mainSection div:visible');
var inVisibleObj = $('.mainSection div:hidden');
visibleObj.fadeOut(500, function() {
inVisibleObj.fadeIn(500);
});
});
});
div.app {
margin:50px auto;
width: 400px;
height: 400px;
border-radius:10px;
overflow: hidden;
position: relative;
}
div.app > .blur {

}
div.mainSection{

}
div.dashboard{
width:100%;
height:15%;
background:rgba(255,0,0,0.5);

}
div.mainSection > .panel1,
div.mainSection > .panel2 {

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

</div>

To make one of the panels hidden in the first place, I'd use a css class called hidden:
.hidden{
display : none;
}
Which simply makes what it sounds like, hiding the element.
Than, I'd set this class in the HTML decleration:
<div class="panel2 hidden">Panel2</div>
That will hide panel2 on page load, and by that you don't have to hide it using js code.
Than, I'd use a helper css class called panel that stands to be a panel identifier (you can either use the data attribute, or any other way of identifying those elements).
For 5 panels, it would look like this:
<div class="panel panel1">Panel1</div>
<div class="panel panel2 hidden">Panel2</div>
<div class="panel panel3 hidden">Panel3</div>
<div class="panel panel4 hidden">Panel4</div>
<div class="panel panel5 hidden">Pane5</div>
At last, to make this work for any number of panels you want (not necesseraly 2), I'd use a "carousel" effect to toggle the panels visibility, while having a way to keep track with them (adding and removing the hidden class), and use the fadeIn/fadeOut effect. (again, instead of identifying the panels using the panel1,panel2,panel3... classes, you can always use the data attribute (please read more about it in jQuery docs), or in any other way).
var currentPanel = 1;
$(".grid-button").on("click", function() {
$(".grid").toggleClass("open close");
$(".panel"+currentPanel).fadeOut("normal", function(){
$(this).addClass('hidden');
});
currentPanel = currentPanel >= $(".panel").length ? 1 : currentPanel+1;
$(".panel"+currentPanel).fadeIn().removeClass('hidden');
});
Just note that the hidden class actually "looses" it's functionality after the first click, since jQuery changes the display property inline, but I think that it might not be harmful to keep them anyway (it will be easier to track them).
You can see an example here: https://jsfiddle.net/j79y5kdb/3/
