detect if 'DOMContent already in browser cache - javascript

Hi I am trying to display a loader section.
Which section will increase 0 to 100% during page load.
for that I tried below code.
Problem is that when I tried to page soft reload with browser cache that screen is not moving from bottom to top (with height 0% to 100%).
But in hard refresh after removing browser cache it's ok.
;(function(){
function id(v){return document.getElementById(v); }
function loadbar() {
var ovrl = id("overlay"),
prog = id("progress"),
stat = id("progstat"),
container = id("container"),
img = document.images,
c = 0;
tot = img.length;
var decrease = 100;
function imgLoaded(){
c += 1;
var perc = ((100/tot*c) << 0) +"%";
var percvh = ((100/tot*c) << 0) +"vh";
ovrl.style.height = percvh;
decrease = decrease - perc;
prog.style.width = perc;
stat.innerHTML = "Loading "+ perc;
if(c===tot) return doneLoading();
}
function doneLoading(){
setTimeout(function(){
ovrl.style.height = '100vh';
ovrl.style.transform= "translate3d(0, -100%, 0)";
//ovrl.style.transition = "transform 2s ease-in-out";
}, 1200);
}
for(var i=0; i<tot; i++) {
var tImg = new Image();
tImg.onload = imgLoaded;
tImg.onerror = imgLoaded;
tImg.src = img[i].src;
}
}
document.addEventListener('DOMContentLoaded', loadbar, false);
}());

Slideshows(Multiple) for HTML/Webpage

I am attempting to put two slideshows on the same page, both of which would be ran by the same css, and java script. My issue is that I can not seem to figure out why my second slideshow is pushing one of the images down.

If anyone can explain what I have done wrong, I would appreciate it and any other advice as well! Thank you

Ids should be unique within the document, but you are styling w/ id selectors and multiple elements with the same id. Switch to classes. E.g. -
Use
class="image_slider"
and
.image_slider { <yourcss> }

Why does this slideshow change transition time when it reaches the end?

Hi I have made a basic slideshow which slides up every few seconds.
I've thrown in a if statement to roll this back to the start, why can I not get this to go back to the start quicker? It just seems to stay on the original transition time?
var level = -300;
function slideshow() {
var cont = document.getElementById('container');
cont.style.transitionDuration = "3s";
cont.style.transform = "translate(-0px," + level + "px)";
level = level - 300;
if (level == -900) {
flipback()
}
}
function flipback() {
level = 0;
cont.style.transitionDuration = "1s";
cont.style.transform = "translate(-0px," + level + "px)";
slideshow();
}
setInterval(slideshow, 6000)
body {
padding:0px;
margin:0px;
}
#display {
width:450px;
height:300px;
overflow:hidden;
margin:150px 450px;
}
#container {
}
#container img {
height:300px;

float:left;
}

Animation cards Javascript and CSS

I would move cards on click and put them on the green table with animation of transition; then when cards are on the table, when i click on them, they must show their front face, and then return with back face.
The code doesn't work, i see the back cards on the left of the page but when i click on nothing happens.
var card_value = ['1B', '2B', '3B', '4B', '5B', '6B'];
var card_left = [];

var el = document.getElementById("card_" + id);

How to build simple jQuery image slider with sliding or opacity effect?

Some of us might not want to use ready plugins because of their high sizes and possibilty of creating conflicts with current javascript.
I was using light slider plugins before but when customer gives modular revise, it became really hard to manipulate. Then I aim to build mine for customising it easily. I believe sliders shouldn't be that complex to build from beginning.
What is a simple and clean way to build jQuery image slider?
Before inspecting examples, you should know two jQuery functions which i used most.
index() returns value is an integer indicating the position of the first element within the jQuery object relative to its sibling elements.
eq() selects of an element based on its position (index value).
Basicly i take selected trigger element's index value and match this value on images with eq method.
- FadeIn / FadeOut effect.
- Sliding effect.
- alternate Mousewheel response.
​html sample:
<ul class="images">
<li>
<img src="images/1.jpg" alt="1" />
</li>
<li>
<img src="images/2.jpg" alt="2" />
</li>
...
</ul>
<ul class="triggers">
<li>1</li>
<li>2</li>
...
</ul>
<span class="control prev">Prev</span>
<span class="control next">Next</span>
OPACITY EFFECT: jsFiddle.
css trick: overlapping images with position:absolute
ul.images { position:relative; }
ul.images li { position:absolute; }
jQuery:
var target;
var triggers = $('ul.triggers li');
var images = $('ul.images li');
var lastElem = triggers.length-1;
triggers.first().addClass('active');
images.hide().first().show();
function sliderResponse(target) {
images.fadeOut(300).eq(target).fadeIn(300);
triggers.removeClass('active').eq(target).addClass('active');
}
SLIDING EFFECT: jsFiddle.
css trick: with double wrapper and use child as mask
.mask { float:left; margin:40px; width:270px; height:266px; overflow:hidden; }
ul.images { position:relative; top:0px;left:0px; }
/* this width must be total of the images, it comes from jquery */
ul.images li { float:left; }
jQuery:
var target;
var triggers = $('ul.triggers li');
var images = $('ul.images li');
var lastElem = triggers.length-1;
var mask = $('.mask ul.images');
var imgWidth = images.width();
triggers.first().addClass('active');
mask.css('width', imgWidth*(lastElem+1) +'px');
function sliderResponse(target) {
mask.stop(true,false).animate({'left':'-'+ imgWidth*target +'px'},300);
triggers.removeClass('active').eq(target).addClass('active');
}
Common jQuery response for both slider:
( triggers + next/prev click and timing )
triggers.click(function() {
if ( !$(this).hasClass('active') ) {
target = $(this).index();
sliderResponse(target);
resetTiming();
}
});
$('.next').click(function() {
target = $('ul.triggers li.active').index();
target === lastElem ? target = 0 : target = target+1;
sliderResponse(target);
resetTiming();
});
$('.prev').click(function() {
target = $('ul.triggers li.active').index();
lastElem = triggers.length-1;
target === 0 ? target = lastElem : target = target-1;
sliderResponse(target);
resetTiming();
});
function sliderTiming() {
target = $('ul.triggers li.active').index();
target === lastElem ? target = 0 : target = target+1;
sliderResponse(target);
}
var timingRun = setInterval(function() { sliderTiming(); },5000);
function resetTiming() {
clearInterval(timingRun);
timingRun = setInterval(function() { sliderTiming(); },5000);
}
Here is a simple and easy to understand code for Creating image slideshow using JavaScript without using Jquery.
<script language="JavaScript">
var i = 0; var path = new Array();
// LIST OF IMAGES
path[0] = "image_1.gif";
path[1] = "image_2.gif";
path[2] = "image_3.gif";
function swapImage() { document.slide.src = path[i];
if(i < path.length - 1) i++;
else i = 0; setTimeout("swapImage()",3000);
} window.onload=swapImage;
</script>
<img height="200" name="slide" src="image_1.gif" width="400" />

I have written a tutorial on creating a slideshow, The tutorial page
In case the link becomes invalid I have included the code in my answer below.
the html:
<div id="slideShow">
<div id="slideShowWindow">
<div class="slide">
<img src="”img1.png”/">
<div class="slideText">

<p>This is the slide text</p>
</div> <!-- </slideText> -->
</div> <!-- </slide> repeat as many times as needed -->
</div> <!-- </slideShowWindow> -->
</div> <!-- </slideshow> -->
