jQuery: show/hide are instantaneous - javascript

I've one div that contains to other one:
<div>
<div id="card-container">....</div>
<div id="wait-for-result-container" style="display: none;">...</div>
</div>
On some event, I want to change the displayed element, with a fadeIn/fadeOut effect.
$('#card-container').hide(5000);
$('#wait-for-result-container').show(5000);
(I put some big number to really see the effect)
But when I trigger my effect, it is instantaneous, there is no fade-in/fade-out.
I'm not sure it matters, but I'm using jquery-3.1.1 and bootstrap 4 alpha.
Any idea what is going wrong?
EDIT
As asked, here is some clarification.
The element that I'm trying to hide is hided immediatly and the one I show is appearing immediately.
EDIT
I tried to put a demo here with the code from above:
$('#myBt').click(function(){
$('#card-container').hide(5000);
$('#wait-for-result-container').show(5000);
});
<script src="https://code.jquery.com/jquery-3.1.1.slim.min.js"></script>
<div>
<div id="card-container">First one</div>
<div id="wait-for-result-container" style="display: none;">Second one</div>
</div>
<button id="myBt">Click me</button>

If you can use the full version of jQuery, give jQuery fadeOut and fadeIn a try :)
$('#myBt').click(function(){
var duration = 5000;
$('#card-container').fadeOut(duration);
$('#wait-for-result-container').delay(duration).fadeIn(duration);
});
<script src="https://code.jquery.com/jquery-3.1.1.min.js"></script>
<div>
<div id="card-container">First one</div>
<div id="wait-for-result-container" style="display: none;">Second one</div>
</div>
<button id="myBt">Example1</button>
If you have to stick with the slim version, you can use setInteval
$('#myBt').click(function(){
var duration = 5000;
var op = 0.9; // initial opacity
var timer1 = setInterval(function () {
if (op <= 0.1){
clearInterval(timer1);
op = 0;
$('#card-container')[0].style.display = 'none';
}
$('#card-container')[0].style.opacity = op;
op -= 100/duration;
}, 100);
var timer2 = setInterval(function () {
if (op <= 0){
$('#wait-for-result-container')[0].style.opacity = 0;
$('#wait-for-result-container').show();
}
if (op >= 1){
clearInterval(timer2);
}
if($('#wait-for-result-container').is(':visible')){
$('#wait-for-result-container')[0].style.opacity = op;
op += 100/duration;
}
}, 100);
});
<script src="https://code.jquery.com/jquery-3.1.1.min.js"></script>
<div>
<div id="card-container">First one</div>
<div id="wait-for-result-container" style="display: none;">Second one</div>
</div>
<button id="myBt">Example2</button>

set and clear interval multiple times

On the first slide of my slider I've got some text that changes within an interval.
This is the jQuery to do this:
<script>
var x = 0;
var text = ["STRATEGICALLY", "COST-EFFECTIVELY", "EFFICIENTLY", "EXCEPTIONALLY"];
var counter = 0;
var elem = document.getElementById("banner-change");
var intervalID = setInterval(change, 1500);
function change() {
jQuery(elem).fadeOut('slow', function() {
jQuery(elem).text(text[counter++]);
if (counter >= text.length) {
counter = 0;
}
jQuery(elem).fadeIn('fast');
if (++x === 5) {
window.clearInterval(intervalID);
}
});
}
</script>
The slider looks something like this (The shortened code):
<div id="myCarousel" class="hp-top carousel fade" data-ride="carousel" data-interval="6000">
<div class="carousel-inner">
<div class="item active"><img src="" alt="Chicago"/><div class="carousel-caption">
<div class="carousel-caption-inner">
<p class="slider-text small"><span class="slider-padding">What makes</span> us <span class="slider-green">specialists?</span></p>
<p class="slider-text">We just do ip</p>
<p class="slider-text"><span id="banner-change" class="slider-green">exceptionally</span></p>
</div>
</div>
</div>
So the words in <span id="banner-change" class="slider-green"> keep changing. This works fine. However, it only works for the first time the first banner is shown. Which makes sense as I'm clearing the interval as each word is only supposed to show once, but not sure how to do this so that every time the first banner shows it starts the interval again?
You can use the carousel evelts to trigger action.
e.relatedTarget will then refer to the slide, that is sliding into view.
So if you give it a unique id, you can identify it and run whatever action afterwards.
$('#myCarousel').on('slide.bs.carousel', function (e) {
if (e.relatedTarget.id === 'firstSlide') // do something
})

add div using appendChild

This code is supposed to be looping and adding multiple divs, but it isn't working. When I click it, only one div appears. If I click again, nothing happens.
<body>
<div class="start" >
<div id = "coba">
</div>
<div id = "cobi">
</div>
</div>
<script>
var divs = document.getElementById("coba").addEventListener("click", function () {
for (var i = 1; i < 100; i++) {
var di = document.createElement('div');
document.getElementById('coba').appendChild(di);
}
});
</script>
</body>
Thanks for your help
Your code does not work because you did not do anything with the variable "i" in the for statement. If you look at the fiddles of user2181397 & meghan Armes you will see how they added a line in the script to put it to work.
I tested the below in my IDE and it works just fine:
<body>
<div class="start" style="margin-top:50px; color:black;">
<div id = "coba">
<p>Click Me</p>
</div>
<div id = "cobi">
</div>
</div>
<script>
var divs = document.getElementById("coba").addEventListener("click", function() {
for (var i = 1; i < 100; i++) {
var di = document.createElement('div');
di.innerHTML=i;
document.getElementById('coba').appendChild(di);
}
});
</script>
</body>

Infinite looping slideshow of HTML pages with jQuery

I'm trying to make a slideshow of HTML pages outputting to a screen 24/7. What I have works, but different slides need different intervals. How can I achieve this?
The output is fullscreen with a fixed footer which displays logo, some messages and the time.
jQuery
$(document).ready(function () {
var div = $('#content'); // Target iFrame
var slides = ['welcome','movie']; // Which slides
var time = 5000; // Default interval
var folder = 'slides'; // Folder where the HTML slides are
var extension = 'html';
var index = 1; // Skip first (0), already loaded by default SRC from iframe
$.ajaxSetup({
cache: false // Maybe not neccesary any more, before I used a div and $.load() instead of iframe
});
function loop() {
if (index === slides.length) { // If at end
index = 0; // Start again
}
div.attr('src', folder + '/' + slides[index] + '.' + extension); // Load next one
index++;
}
setInterval(function () {
loop();
}, time);
});
HTML
<iframe id="content" src="slides/welcome.html" width="100%" height="100%" frameborder="0"></iframe>

</div>
</div>
<div class="col-lg-3">
<div id="time"></div>
</div>
</div>
</div>
Using setTimeout and buttons to start and stop the loop.

Image not hiding correctly

I made a JQuery carousel from scratch, so far the code is good and it works quite nice.
The main issue is when I try and use the fadeOut function alongside the fadeIn function, the images stack on top of each other.
I cant figure out how to make them overlap.
I tried to play around with absolute positioning but had no luck.
You can clearly see it when you go on my website http://techyhesh.com/Dogs/
html
<div class="carousel">
<div id="background-slideshow">
<div style="display: none;" id="img1" class="slides">
<img src="/2015/03/Carosuel2.png">
<div class="textblock">
<p class="carousel-text1">Slider 1</p>
<p class="carousel-text2">His nose gets into everything</p>
</div>
</div>
<div style="display: block;" id="img2" class="slides">
<img src="/2015/03/Carosuel.png">
<div class="textblock">
<p class="carousel-text1">Slider 2</p>
<p class="carousel-text2">His nose gets into everything</p>
</div>
</div>
<div style="display:none;" class="SlideJSON">2</div>
</div>
</div>
JS
jQuery(document).ready(function($) {
var slides= $(".JSONNumber").html();
var slides= parseInt(slides);
var animateInterval;
var i = 1;
var x = 2;
function animate() {
$("#img" + i).fadeOut(2000)
$("#img" + x).fadeIn(2000);
if (i == slidenumber) {
$("#img1").fadeIn(2000);
i = 1;
x = 2;
} else {
i++;
x++;
}
}
animateInterval = setInterval(animate, 3000);
})
As per your HTML, The selector you've used is wrong.
$("#img" + i)
It should be
$("#slideimg" + i)
in your slides css, just add display: inline-block;

Using JQuery how to show and hide different div's onClick event

I would like to show a div based on the Onclick event of an link.
First Click - Show div1
Second Click - Hide remaining div's and Show div2
Third Click - Hide remaining div's and show div3
Fourth Click - Hide remaining div's and show div1 => repeat the loop and goes on..
Code Follows:
<div class="toggle_button">
Toggle
</div>
<div id='div1' style="display:none;">
<!-- content -->
</div>
<div id='div2' style="display:none;">
<!-- content -->
</div>
<div id='div3' style="display:none;">
<!-- content -->
</div>
Jquery Code :
$(document).ready(function() {
$("#toggle_value").click(function(){
$("#div1").show("fast");
$("#div2").show("fast");
$("#div3").show("fast");
});
});
The above code shows all divs on first click itself but it should show div1 on first click as mentioned.
I'll try my shot.
EDIT:
After second though, to avoid global variable use it's better to do the following
$(document).ready(function() {
$("#toggle_value").click((function(){
var counter = 0;
return function()
{
$("#div" + counter).hide("fast");
counter = (counter % 3) + 1;
$("#div" + counter).show("fast");
}
})());
});
You should add a counter in the function.
$(document).ready(function() {
var count = 0;
$("#toggle_value").click(function(){
if (count == 0) {
$("#div1").show("fast");
$('#div2').hide();
count++;
}
else if (count == 1) {
$("#div2").show("fast");
...
count++;
}
else if (count == 2) {
$("#div3").show("fast");
....
count++;
}
else {
$('div').hide();
count=0;
}
});
});
How about this
Working Example here - add /edit to URL to edit the code
$('html').addClass('js'); // prevent hiding divs on DOM ready from 'flashing'
$(function() {
var counter = 1;
$('#toggle_value').click(function() {
$('div','#container')
// to stop current animations - clicking really fast could originally
// cause more than one div to show
.stop()
// hide all divs in the container
.hide()
// filter to only the div in question
.filter( function() { return this.id.match('div' + counter); })
// show the div
.show('fast');
// increment counter or reset to 1 if counter equals 3
counter == 3? counter = 1 : counter++;
// prevent default anchor click event
return false;
});
});

This could easily be wrapped up in a plugin
A simple way would be to introduce a variable that tracked clicks, so something like this:
var tracker = 0;
$(document).ready(function() {
$("#toggle_value").click(function(){
if(tracker == 0)
{
$("#div1").show("fast");
}else if(tracker ==1)
etc etc
tracker ++;
});
});
My solution is a little different - I'd do it dependant on the state of the divs at the current time (on click). See below for what I mean by this.
$(document).ready(function() {
$("#toggle_value").click(function(){
if ($("#div1).is(':visible')) { // Second click
// Hide all divs and show d2
$("#div1").hide();
$("#div2").show("fast");
$("#div3").hide();
$("#div4").hide();
} else if ($("#div2").is(':visible')) { // Third click
// follow above example for hiding all and showing div3
} else if ($("#div3").is(':visible')) { // Fouth click
// follow above example for hiding all and showing div1
} else { // first click
// All divs should be hidden first. Show div1 only.
$("#div1").show("fast");
}
});
});
Just to warn you - I have not tested this code :)
Based upon the following for determining visibility: http://docs.jquery.com/Frequently_Asked_Questions#How_do_I_determine_the_state_of_a_toggled_element.3F
Hope it helps
I prefer to use "filter" method and make a little easier work with counter:
(function () {
var divCounter = 0, divs;
$(function () {
divs = $('#div1, #div2, #div3');
$('#toggle_value').click(function (e) {
divs.hide() // hide other divs
.filter(function (index) { return index == divCounter % 3; }) // select appropriate div
.show('fast'); // and show it
divCounter++;
});
});
})();
I would probably do something like: (The following assumes all your <div>s are in a container with id "container")
$(document).ready(function() {
var $allDivs = $("#container > div");
var counter = 0;
$("#container > div").click(function(){
counter = counter < $allDivs.length - 1 ? counter + 1 : 0;
$allDivs.not(":eq("+counter +")").hide("fast");
$allDivs.eq(counter).show("fast");
});
});
The .toggle function in jQuery takes any number of argument functions, so the problem is already solved. See the docs under Events.
$("#toggle_value").click(function()
{
$("#div" + (++c) % 3).show().siblings().hide();
}
var c = 1;
$("#toggle_value").click(function()
{
$("#div" + c).hide("fast");
$("#div" + ++c).show("fast");
if (c > 3) c=1;
});
First You have to add query basic file:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
Then you have to add the following code:
<script type="text/javascript">
$(document).ready(function () {
$("#hide").click(function(){
$(".slider_area").hide(1000);
$("#show").css("display","block");
$("#hide").css("display","none");
});
$("#show").click(function(){
$(".slider_area").show(1000);
$("#show").css("display","none");
$("#hide").css("display","block");
});
});
</script>
Add the code above into the header portion and the code below in the body portion.
<img src="images/hide-banner.png" id="hide" class="link right"/>
<img src="images/show-banner.png" id="show" class="link right dis" />
The code is ready for the different image click for show and hide div.
<div id="div_<%=id>">
</div>
<div id="Hide_<%=id>" style="display:none;">
</div>
<div id="div_<%=id>">
</div>
<div id="Hide_<%=id>" style="display:none;">
</div>
<div id="div_<%=id>">
</div>
<div id="Hide_<%=id>" style="display:none;">
</div>
<div id="div_<%=id>">
</div>
<div id="Hide_<%=id>" style="display:none;">
</div>
<script>
var temp = 0;
var temp1 = 0;
$("#div_<%=id>").click(function(){
if (temp1 == 0) {
$('#' + temp).hide();
temp = 'Hide_<%=id>';
$('#Hide_<%=id>').show();
temp1 = 1;
}
else{
$('#' + temp).hide();
temp = 'Hide_<%=id>';
$('#Hide_<%=id>').show();
temp1 = 0;
}
});
</script>
