I am trying to make a JavaScript multiple image uploader that uploads image previews to a slider, but I am having some issues. So far it looks like I was able to get the images to upload into the slider, but the problem seems to happen with my i variable - when I try to increment it, it stays the same, not allowing my next and previous slider arrows from working. If anyone knows how to get this slider working properly, I would appreciate the help.
JS Code:
$('#_uploadImages').click(function() {
$('#_imagesInput').click()
})
$('#_imagesInput').on('change', function() {
handleFileSelect();
});
function handleFileSelect() {
//Check File API support
if (window.File && window.FileList && window.FileReader) {
var files = event.target.files; //FileList object
var output = document.getElementById("frames");
for (var i = 0; i < files.length; i++) {
var file = files[i];
//Only pics
if (!file.type.match('image')) continue;
var picReader = new FileReader();
picReader.addEventListener("load", function (event) {
var picFile = event.target;
console.log(event);
current_i = i;
prev_i = current_i - 1;
next_i = current_i + 1;
//var div = document.createElement("div");
//div.innerHTML = div.innerHTML + "<img class='thumbnail' src='" + picFile.result + "'" + "title='" + picFile.name + "'/>";
//output.insertBefore(div, null);
////output.innerHTML = output.innerHTML + "<img class='thumbnail' style='max-width:500px' src='" + picFile.result + "'" + "title=''/>"; // TODO: Enter Title
output.innerHTML = output.innerHTML + '<li id="slide-' + current_i + '" class="slide">' + "<img src='" + picFile.result + "'" + "title=''/>" + '<nav>' + '<a class="prev" href="#slide-' + prev_i + '">←</a>' + '<a class="next" href="#slide-' + next_i + '">→</a>' + '</nav>' + '<li>'; // TODO: Enter Title
});
//Read the image
picReader.readAsDataURL(file);
}
//output.innerHTML = output.innerHTML + '<li class="quicknav">' + '<ul>' + '<li></li>' + '<li></li>' + '<li></li>' + '</ul>' + '</li>'
} else {
console.log("Your browser does not support File API");
}
}
JSFiddle: http://jsfiddle.net/Hybridx24/yfr57u6w/
The problem with the code is that by the time the load event executes - the for loop has already incremented. So if two images are added - the value of i when the load event is executing is already 2.
One way to solve this is to add the value of i to an array and retrieve it in the event listener one by one:
var arrFilesCount = [];
for (var i = 0; i < files.length; i++) {
arrFilesCount.push(i); //push to array
var file = files[i];
//Only pics
if (!file.type.match('image')) continue;
var picReader = new FileReader();
picReader.addEventListener("load", function (event) {
var picFile = event.target;
current_i = arrFilesCount.shift(); // get from array instead of using i
prev_i = current_i - 1;
next_i = current_i + 1;
...
...
Corresponding jsFiddle here
Now, this array can also be used for determining the first/last element and thereby using this to go from last to first element. Because we cannot be sure when the event listener will execute (say if there are 100 images the first event listener may execute when the count of loop has reached 5 or 10), so I've used two loops instead of one. The first loop just to populate the array.
var arrFilesCount = [];
for (var i = 0; i < files.length; i++) {
arrFilesCount.push(i);
}
Lets use this to find the first and last elements
current_i = arrFilesCount.shift();
if(current_i === 0){
prev_i = files.length - 1; //This is for the first element. The previous slide will be the last image. (i=length-1)
}
else{
prev_i = current_i - 1;
}
if(arrFilesCount.length === 0){
next_i = 0; //This is for the last element. The next slide will be the first image (i=0)
}
else{
next_i = current_i + 1;
}
See this jsFiddle.
Finally, there can be scenarios where the user first adds a couple of images then clicks on upload button again and adds a couple of more images. In this case we need to correct the existing href. The elements which we need to correct are the next of last and prev of first. This can be done using:
var start = $(output).find('li').length;
var end = start+ files.length;
if(start !== 0){
$(output).find('li > nav > a.prev').first().attr('href','#slide-' + (end-1));
$(output).find('li > nav > a.next').last().attr('href','#slide-'+start);
}
So the final jsFiddle will be something like this.
Substituted .append() for .innerHTML ; created variable idx to increment .slide li elements ids ; added delegated click event to nav a elements ; added .bind() with this set to picReader , i passed as parameter to picReader onload event ; added file.name to title attribute of img element ; added "dot" navigation with thumbanail of images beneath #frames ; title to arrow navigation
var idx = -1, re = /(.*)(?=\.)/;

Okay, starting over as I'm new at all of this and, as Sebastian points out, the problem is likely elsewhere.
This is a combination lock which was created by Derek Hill. I've reformatted it by cutting its size in half. In doing so, the size of the dial after spinning doesn't work out right -- when you spin the numbers, you can see that the height of the numbers begins dropping and is no longer vertically centered. It creeps down by about 0.5px each time.
I first notice the problem at the variable "temporTopEarlier". I cannot understand why the "top" for the dial is 0.5px more than it should be (-157 instead of -157.5). I think this is causing my problems. I expected a truncation of decimals, but I don't see where that would happen.
I'm new at this, so apologies for the many poor elements to the code, format, and question. Thanks!

I have searched extensively for the same but none of the solution worked so asking here
I want to change the background image [basically change the class of an element], in a loop. But the really tricky part for me [being new to JavaScript] is that setTimeOut stops after a fix number of times. Here's the code:
function addHomeInnerClass(selector, imageNumber = 0) {
imageNumber += 1;
if (imageNumber === 1) {
selector.classList.add('home-content-1');
}
if (imageNumber === 2) {
selector.classList.add('home-content-2');
}
if (imageNumber === 3) {
selector.classList.add('home-content-3');
}
if (imageNumber === 4) {
selector.classList.add('home-content-4');
imageNumber = 0;
}
setTimeout(() => addHomeInnerClass(selector, imageNumber), 1000);
}
document.addEventListener('DOMContentLoaded', function() {
const homeInner = document.querySelector('.home-inner');
addHomeInnerClass(homeInner, 0);
});
Here's my HTML section for the same:
<section class="home" id="home">
<div class="home-inner">
</div>
</section>
Here's my CSS3:
.home {

I know CSS & HTML code hardly matter here but if I could get some other method to do what I want to, that would be great.
What I want to do?
Use pure javascript to get the fade in and fadeout image effect.
Where am I stuck?
Cannot figure out how to run setTimeOut infinite times?
NOTE: I don't want to use any third party library. It's a learning project.
As I said in a comment, the problem isn't that the timer stops running. It's that you're not removing the old classes when you add the new one. Here's how you could do that while also simplifying the code:
function addHomeInnerClass(selector, imageNumber = 0) {
selector.classList.remove('home-content-' + imageNumber);
imageNumber = imageNumber % 4 + 1;
selector.classList.add('home-content-' + imageNumber);
setTimeout(() => addHomeInnerClass(selector, imageNumber), 1000);
}
Live Example (I modified the CSS at bit to make it easy to see the changes; I also added the missing } after the .home rule):
function addHomeInnerClass(selector, imageNumber = 0) {
selector.classList.remove('home-content-' + imageNumber);
imageNumber = imageNumber % 4 + 1;
selector.classList.add('home-content-' + imageNumber);
setTimeout(() => addHomeInnerClass(selector, imageNumber), 1000);
}
document.addEventListener('DOMContentLoaded', function() {
const homeInner = document.querySelector('.home-inner');
addHomeInnerClass(homeInner, 0);
});
.home {
height: 88.98vh;
}
.home-content-1 {
height: 98%;
border-bottom-right-radius: 20rem;
background: url("https://via.placeholder.com/100/0000C0/FFFFFF?text=1") no-repeat center center/cover;
z-index: 1;
}
.home-content-2 {
height: 98%;
border-bottom-right-radius: 20rem;
background: url("https://via.placeholder.com/100/0000C0/FFFFFF?text=2") no-repeat center center/cover;
z-index: 1;
}
.home-content-3 {
height: 98%;
border-bottom-right-radius: 20rem;
background: url("https://via.placeholder.com/100/0000C0/FFFFFF?text=3") no-repeat center center/cover;
z-index: 1;
}
.home-content-4 {
height: 98%;
border-bottom-right-radius: 20rem;
background: url("https://via.placeholder.com/100/0000C0/FFFFFF?text=4") no-repeat center center/cover;
z-index: 1;
}
}
<section class="home" id="home">
<div class="home-inner">
</div>
</section>
As suggested in the comments, setInterval is exactly tailored for your needs. It allows you to run a function (like addHomeInnerClass in your case) every x milliseconds. Please note however that using this function requires you to change your imageNumber logic a bit.
Additionally, as mentioned in the comments as well, you should remove the old classes before adding new ones.
I would suggest the following approach:
let imageNumber = 0;
function addHomeInnerClass(selector) {
selector.classList.remove('home-content-' + imageNumber);
imageNumber++;
if(imageNumber === 5) imageNumber = 1;
selector.classList.add('home-content-' + imageNumber);
}
document.addEventListener('DOMContentLoaded', function() {
const homeInner = document.querySelector('.home-inner');
setInterval(() => addHomeInnerClass(homeInner), 1000);
});
Requirement:
Needed to add custom scale numbers to the range slider from the Rangeslider.js plugin, so that whenever it slides over the horizontal line it needs to display the selected number range from the console
Actual Results:
Whenever I tried to add custom numbers the whole design including marker gets ruined. Here is the below codes of the snippet which needs to add custom number scales
Code I:
init(1, 10);
function init(min, max) {
$("#io").append($("<div style='text-align:center;'><div><input type='range' id='slider' min='" + min + "' max='" + max + "' step='1' value='3' data-rangeslider><output id='val'></output></div></div>"));
$('head').append('<link href="https://cdnjs.cloudflare.com/ajax/libs/rangeslider.js/2.3.2/rangeslider.css" rel="stylesheet" type="text/css">');
$.getScript("https://cdnjs.cloudflare.com/ajax/libs/rangeslider.js/2.3.2/rangeslider.js")
.done(function(script, textStatus) {
console.log(textStatus);
//Preform here
initRangeSlider($("#slider"));
});
}
function initRangeSlider(ele) {
ele.rangeslider({
// Deactivate the feature detection
polyfill: false,
// Callback function
onInit: function() {
//valueOutput(this.$element[0]);
},
// Callback function
onSlide: function(position, value) {
console.log('onSlide');
console.log('position: ' + position, 'value: ' + value);
},
// Callback function
onSlideEnd: function(position, value) {
console.log('onSlideEnd');
console.log('position: ' + position, 'value: ' + value);
}
});
}

Code II:
Here the below code of snippets doesn't seem to fit for my project. This was my actual result when I tried to integrate. So I need to modify the above code I with the below code II snippets
var $r = $('input[type="range"]');
var $ruler = $('<div class="rangeslider__ruler" />');
// Initialize
$r.rangeslider({
polyfill: false,
onInit: function() {
$ruler[0].innerHTML = getRulerRange(this.min, this.max, this.step);
this.$range.prepend($ruler);
}
});
function getRulerRange(min, max, step) {
var range = '';
var i = 0;
while (i <= max) {
range += i + ' ';
i = i + step;
}
return range;
}

I am using this clock in my homepage.
It isn´t working in IE.
What is the problem with IE and how I can solve it?

Thank you all for your tipps and support!
I solved the problem. Older IE-Versions couldn´t read the DATE format..
i had:
flipclock('2016 01 16 11:00:00');
but for IE it should be:
flipclock('2017-01-16T11:00:00.000Z');
I'm currently styling HTML5 input type range using below code:
input[type="range"]{
-webkit-appearance: none;
-moz-apperance: none;
width: 100%;
height: 8px;
padding: 0 20px;
background: #024069;
border-radius: 2px;
margin-top: 25px;
}
input[type="range"]::-webkit-slider-thumb{
-webkit-appearance:none;
-moz-apperance:none;
width:25px;
height:25px;
-webkit-border-radius:20px;
-moz-border-radius:20px;
-ms-border-radius:20px;
-o-border-radius:20px;
border-radius:20px;
background-image:-webkit-gradient(linear, left top, left bottom, color-stop(0, #fefefe), color-stop(0.49, #d7d7d7), color-stop(0.51, #d1d1d1), color-stop(1, #c8c8c8) );
border: 1px solid #787878;
}
This is all good. But now I'm trying to have two different colours on the actual slider so left of the thumb is blue and right of the thumb is black.
I tried :before but it didn't work. How can we achieve this?
Here's some JavaScript that updates the colour of the bar when you change the value.
input.oninput = function () {
var value = (input.value - input.min)/(input.max - input.min);
input.style.backgroundImage = [
'-webkit-gradient(',
'linear, ',
'left top, ',
'right top, ',
'color-stop(' + value + ', blue), ',
'color-stop(' + value + ', red)',
')'
].join('');
};
onload = function() {
var inputs = document.querySelectorAll('input[type=range]');
for (var i = 0; i < inputs.length; i++) {
input = inputs[i]
input.oninput = function () {
var value = (input.value - input.min)/(input.max - input.min);
input.style.backgroundImage = [
'-webkit-gradient(',
'linear, ',
'left top, ',
'right top, ',
'color-stop(' + value + ', blue), ',
'color-stop(' + value + ', red)',
')'
].join('');
};
}
};
body {
margin: 20px;
}
input[type="range"]{
-webkit-appearance: none;
-moz-apperance: none;
width: 200px;
height: 8px;
padding: 0;
border-left: 20px solid blue;
border-right: 20px solid red;
background: #024069;
border-radius: 2px;
margin-top: 25px;
background-image: -webkit-gradient(
linear,
left top,
right top,
color-stop(0.2, blue),
color-stop(0.2, red)
);
outline: none;
}
input[type="range"]::-webkit-slider-thumb{
-webkit-appearance:none;
-moz-apperance:none;
width:25px;
height:25px;
-webkit-border-radius:20px;
-moz-border-radius:20px;
-ms-border-radius:20px;
-o-border-radius:20px;
border-radius:20px;
background-image:-webkit-gradient(linear, left top, left bottom, color-stop(0, #fefefe), color-stop(0.49, #d7d7d7), color-stop(0.51, #d1d1d1), color-stop(1, #c8c8c8) );
border: 1px solid #787878;
}

Thanks to #adamvert for suggesting to use oninput instead of onchange.
You'll need JS to do this the way you need. I assume you need the bar-coloring to work correctly even when you slide the thing. i.e. blue to the left and black to the right of the thumb.
Check this demo: http://fiddle.jshell.net/tv3bx/2/
Code:
function colorTheBar(slider) {
var left = $('.left'), right = $('.right');
console.log(slider.val());
if(left.length == 0) {
left = $('<div>').addClass('left').appendTo('body');
right = $('<div>').addClass('right').appendTo('body');
}
left.css({
left: (slider.offset().left + 20) + 'px',
top: slider.offset().top + 'px',
width: (slider.width() * (parseInt(slider.val())/100)) + 'px',
height: slider.height() + 'px'
});
right.css({
left: (slider.offset().left + 20 + slider.width() * (parseInt(slider.val())/100)) + 'px',
top: slider.offset().top + 'px',
width: (slider.width() * (1 - parseInt(slider.val())/100)) + 'px',
height: slider.height() + 'px'
});
}
$('input').change(function() {
colorTheBar($(this));
});
colorTheBar($('input'));
/* CSS */
.left, .right {
position: absolute;
z-index: 1;
}
.left {
background-color: blue;
}
.right {
background-color: black;
}
The easiest way do that is to use gradients:
CSS
input[type="range"]{
-webkit-appearance: none;
-moz-apperance: none;
width: 100%;
height: 8px;
padding: 0 20px;
background: #0000ff;
background: -moz-linear-gradient(left, #0000ff 0%, #0000ff 50%, #000000 50%, #000000 100%);
background: -webkit-gradient(linear, left top, right top, color-stop(0%,#0000ff), color-stop(50%,#0000ff), color-stop(50%,#000000), color-stop(100%,#000000));
background: -webkit-linear-gradient(left, #0000ff 0%,#0000ff 50%,#000000 50%,#000000 100%);
background: -o-linear-gradient(left, #0000ff 0%,#0000ff 50%,#000000 50%,#000000 100%);
background: -ms-linear-gradient(left, #0000ff 0%,#0000ff 50%,#000000 50%,#000000 100%);
background: linear-gradient(to right, #0000ff 0%,#0000ff 50%,#000000 50%,#000000 100%);
filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#0000ff', endColorstr='#000000',GradientType=1 );
border-radius: 2px;
margin-top: 25px;
}
input[type="range"]::-webkit-slider-thumb{
-webkit-appearance:none;
-moz-apperance:none;
width:25px;
height:25px;
-webkit-border-radius:20px;
-moz-border-radius:20px;
-ms-border-radius:20px;
-o-border-radius:20px;
border-radius:20px;
background-image:-webkit-gradient(linear, left top, left bottom, color-stop(0, #fefefe), color-stop(0.49, #d7d7d7), color-stop(0.51, #d1d1d1), color-stop(1, #c8c8c8) );
border: 1px solid #787878;
}
To customize the gradient i recommend Ultimate CSS Gradient Generator.
