I'm trying to make a website where you can upload an image, then select another one and add it over the uploaded one. I'm using jquery to make the image draggable and resizable and everything works fine, except that I can't add it over the uploaded image.
Here's my code:
code:
$(document).ready(function() {
$(document).on('click', '.block-add', function() {
var a = $(this);
var src = a.find('img:first').attr('src');
var elem = $('<div class="container"><img src="' + src + '" class="blocks" /></div>');
$('.block').append(elem);
elem.draggable();
elem.find('.blocks:first').resizable();
return false;
});
});
.blocks {
width: 10%;
z-index: 9999;
}
.block {
width: 100%;
height: 100%;
border: 1px solid #C8C8C8;
margin: 0px;
background-color: #F0F0F0;
margin-left: auto;
margin-right: auto;
overflow: hidden;
}
.center {
display: block;
margin-left: auto;
margin-right: auto;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="upload">
<input type='file' onchange="readURL(this);" /> <br>
</div>
<br/>
<div class="block">
<div class="background">
<img id="bg" src="" alt="" width="50%" ; height="50%" ; class="center" />
</div>
</div>
<br/>
<div id="existingImges">
<a class="block-add" href="javascript:void(0)"><img class="uploadImage" src="https://pngimg.com/uploads/car_wheel/car_wheel_PNG23300.png" width="200px;" /></a>
<a class="block-add" href="javascript:void(0)"><img class="uploadImage" src="https://pngimg.com/uploads/car_wheel/car_wheel_PNG23300.png" width="200px;" /></a>
<a class="block-add" href="javascript:void(0)"><img class="uploadImage" src="https://pngimg.com/uploads/car_wheel/car_wheel_PNG23300.png" width="200px;" /></a>
<a class="block-add" href="javascript:void(0)"><img class="uploadImage" src="https://pngimg.com/uploads/car_wheel/car_wheel_PNG23300.png" width="200px;" /></a>
</div>
So here's the result in this case:
and here's what I'd like to be after adding a wheel:
As #Troy Bailey and I mentioned, the way to success is the css attribute z-index.
Here the changes:
First step:
Add this above z-index attribute to class .block: z-index: 1;.
Second step:
For your javascript you have to add some lines which increases the z-index attribute s of your created divs, with class .container.
$(document).ready(function() {
$(document).on('click', '.block-add', function() {
var src = $(this).find('img:first').attr('src');
//New line
//First, find out how many images has being added and dragged
var foundAddedDivs = $('.block').find('.container').size();
//New line
//Second, get the current value from recently added 'z-index' from fist step.
var backGroundDivIndex = $('.block').css("z-index");
//New line
//Third: Calulate a new value for 'z-index' for each draggable elements
var zIndex = backGroundDivIndex + foundAddedDivs;
//Modified line
//Forth: Creates a new div and add calculated z-index to draggable element
var elem = $('<div class="container" style="z-index: '+ zIndex +'">
<img src="' + src + '" class="blocks" /></div>');
$('.block').append(elem);
elem.draggable();
elem.find('.blocks:first').resizable();
return false;
});
});
.block-add {z-index: 99;}
/* just increase the z-index of the wheel so it can be in front of the car image */

I have a gallery of images. I want to show a loading gif when an image is clicked. I am passing the same onclick function to all the images with their id as below:
<div id="smallimage1" onclick="imageClicked(this.id)">
<img class="model-img" src="img/model/image1.jpeg"/>
</div>
<div id="smallimage2" onclick="imageClicked(this.id)">
<img class="model-img" src="img/model/image2.jpeg"/>
</div>
<div id="loading" style="margin-top: -65%; display: none; z-index= 9999; position: relative;">
<img src="img/imagepreloader.gif" alt="loading...">
</div>
This is my js :
function imageClicked(id) {
// alert(id);
document.getElementById("loading").style.display = ""; // to display
//alert(loading);
return true;
}
var FirstLoading = true;
function Restoresmallimage() {
if (FirstLoading) {
FirstLoading = false;
return;
}
}
// To disable restoring submit button, disable or delete next line.
document.onfocus = Restoresmallimage;
For the first image its working fine.
But issue is when I am clicking on second image, gif is running on first image and not on the second one. How to resolve this issue? I had defined loading id in each div image.
I think the problem is you never move imagepreloader.gif. Here is my solution to have only one imagepreloader.gif for all images:
HTML:
<div id="smallimage1" onclick="imageClicked(this.id)">
<img class="model-img" src="img/model/image1.jpeg"/>
</div>
<div id="smallimage2" onclick="imageClicked(this.id)">
<img class="model-img" src="img/model/image2.jpeg"/>
</div>
CSS:
div {
display: inline-block;
position: relative;
}
#loading {
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
}
JavaScript:
function constructImagePreloader() {
'use strict';
var imagePreloader = document.createElement('img');
imagePreloader.setAttribute('src', 'images/imagepreloader.gif');
imagePreloader.setAttribute('alt', 'loading...');
imagePreloader.setAttribute('id', 'loading');
return imagePreloader;
}
function imageClicked(id) {
document.getElementById(id).appendChild(constructImagePreloader());
return true;
}
Tell me if it suits your needs. We could go further with code optimization but I wanted to stay close from your code for now. For instance: we could remove the image preloader from the clicked image if another image is clicked.
Try this if it will work,
<div id="smallimage1" onclick="imageClicked(this.id)">
<img class="model-img" src="img/model/image1.jpeg"/>
</div>
<div id="smallimage2" onclick="imageClicked(this.id)">
<img class="model-img" src="img/model/image2.jpeg"/>
</div>
<div id="loading1" style="margin-top: -65%; display: none; z-index:9999; position: relative;">
<img src="img/imagepreloader.gif" alt="loading...">
</div>
<div id="loading2" style="margin-top: -65%; display: none; z-index: 9999; position: relative;">
<img src="img/imagepreloader.gif" alt="loading...">
</div>
And your script will be like this;
function imageClicked(id) {
// alert(id);
var loadingId = $(id).replace('smallimage','loading');
document.getElementById(loadingId).style.display = "block"; // to display
//alert(loading);
return true;
}
So below I have some code of what I'm working with. Right now, if you just launch the website, the #picture div has a background image, and if you press any of the buttons, that picture is replaced with something else.
So what I can't figure out is how the buttons would change what they do after pressing a button. Let's say you click on Button 1 and the background image is replaced. I want the buttons to recognize what background image is in that div and change functions accordingly, in my case, I want them to change what pictures they replace the current one with.
If the current background of #picture is X, you have ABC choices, if the background of #picture is Y, you have DEF choices, would be a TLDR explanation maybe.
<div id="adventure">
<div class="picture">
</div>
<div id="choice">
<button class="button1">Val 1</button>
<button class="button2">Val 2</button>
<button class="button3">Val 3</button>
</div>
</div>
$('.button1').click(function() {
$('.picture').css('background-image',
'url("image1")'
);
});
$('.button2').click(function() {
$('.picture').css('background-image',
'url("image2")'
);
});
$('.button3').click(function() {
$('.picture').css('background-image',
'url("image3")'
);
});
I've probably gone about doing this in a bad way but I'm really at a loss on how I would do this. I can only think up of one way of doing it and that is to have a bunch of if statements depending on what background is in the #picture div but I don't know how to implement that.
This demo relies on the class .active which determines which set of buttons (called .group) are visible, whilst the other .groups remain absent. The #switch button will toggle through each group.
You must name your images according to the id of the button it belongs to.
Example:
HTML of Button
<button id="image_of_sky.png">D</button>
URL to Image
http://domain.com/path/to/image_of_sky.png
jQuery img variable
var img = "http://domain.com/path/to/"+btn;
Snippet
$('.button').click(function() {
var btn = $(this).attr('id');
var img = "https://placehold.it/330x150?text=" + btn;
$('.picture').css('background-image',
'url(' + img + ')'
);
});
$('#switch').click(function() {
var act = $('.group.active');
var next = act.next();
act.removeClass('active');
next.addClass('active');
if (act.attr('id') == "choiceGHI") {
$('#choiceABC').addClass('active');
}
});
#adventure {
width: 395px;
}
.picture {
width: 330px;
height: 150px;
border: 1px outset grey;
}
.group {
width: 330px;
display: none;
padding: 0;
}
.button {
width: 32.5%;
margin: 0;
}
.active {
display: block;
}
#switch {
float: right;
margin: -20px 0 0 0;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="adventure">
<div class="picture"></div>
<div id="choiceABC" class="group active">
<button id="Image1" class="button">A</button>
<button id="Image2" class="button">B</button>
<button id="Image3" class="button">C</button>
</div>
<div id="choiceDEF" class="group">
<button id="Image4" class="button">D</button>
<button id="Image5" class="button">E</button>
<button id="Image6" class="button">F</button>
</div>
<div id="choiceGHI" class="group">
<button id="Image7" class="button">G</button>
<button id="Image8" class="button">H</button>
<button id="Image9" class="button">I</button>

So I'm trying to put together a Javascript toggle for my photography portfolio site. My goal is to be able to click a button labeled Show Only Sunsets and hide every image without a "Sunsets" Class. The code I've come up with below ALMOST works, but there's a major flaw:
This code only preserves the visibility of images such as "1.jpg" below whose Class is exactly/only "Sunsets" (or "NSFW," or whatever). But often I'll need to give images more than one class, for example to differentiate verticals, or images that fall into multiple categories. So I need the code to preserve the visibility of any image such as "2.jpg" below which has "Sunsets" (or whatever) anywhere in its Class.
JS:
<script>
function filterOn(imageClass) {
var image = document.getElementsByTagName('figure');
for (i = 0; i < image.length; i++) {
if (image[i].className != imageClass) {
image[i].style.display = 'none';
}
}
document.getElementById(imageClass + '-off').innerHTML = 'Undo Filter';
document.getElementById(imageClass + '-off').setAttribute('onClick', "filterOff('" + imageClass + "')");
document.getElementById(imageClass + '-off').id = imageClass + '-on';
}
function filterOff(imageClass) {
var image = document.getElementsByTagName('figure');
for (i = 0; i < image.length; i++) {
if (image[i].className != imageClass) {
image[i].style.display = 'inline-block';
}
}
document.getElementById(imageClass + '-on').innerHTML = 'Show Only ' + imageClass;
document.getElementById(imageClass + '-on').setAttribute('onClick', "filterOn('" + imageClass + "')");
document.getElementById(imageClass + '-on').id = imageClass + '-off';
}
</script>
HTML:
<ul>
<li id="Sunsets-off" onClick="filterOn('Sunsets')">Show Only Sunsets</li>
<li id="NSFW-off" onClick="filterOn('NSFW')">Show Only NSFW</li>
</ul>
<img class="Sunsets" src="1.jpg">
<img class="vertical Sunsets" src="2.jpg">
<img class="NSFW vertical" src="3.jpg">
<img class="Architectural" src="4.jpg">
<img class="Sunsets Landscapes" src="5.jpg">
<img class="Abstract" src="6.jpg">
<img class="NSFW LondonAndrews" src="7.jpg">
That test:
if (image[i].className != imageClass) {
will indeed do a check against the whole class string.
There's the classList API for doing what you want, replacing your test with:
if (!image[i].classList.contains(imageClass)) {
I would simplify it by adding a class name to all images so you can easily target all the images, then use a toggled class to hide the images you don't want to see. this also gives you the ability to use css3 animations to fade the images you don't want to see.
function filterOn( clazz ){
// get all the images using the additional img class
var images = slice(document.getElementsByClassName('img'));
// hide all the images
var ret = images.map(function( image ){
image.classList.add('hide');
return image;
})
// reduce the images to only contain those you want to show
.filter(function( image ){
return image.classList.contains( clazz );
})
// show the image by removing the hide class
.forEach(function( image ){
image.classList.remove('hide');
});
}
// show all images
function showAll(){
var images = slice(document.getElementsByClassName('img'));
images.forEach(function( image ){
image.classList.remove('hide');
});
}
// helper function to get an array from an array like object
function slice( arrayLike ){
return Array.prototype.slice.call( arrayLike );
}
.img {
display: block;
float: left;
margin-left: .8em;
border: .3em solid #aaa;
}
.hide {
display: none;
}
.filters {
display: block;
width: 100%;
float: left;
}
.Sunsets {
border: .3em solid orange;
}
.NSFW {
border: .3em solid magenta;
}
<nav class="filters">
<button id="Sunsets-off" onClick="filterOn('Sunsets')">Show Only Sunsets</button>
<button id="NSFW-off" onClick="filterOn('NSFW')">Show Only NSFW</button>
<button id="show-all" onClick="showAll()">Show All</button>
</nav>
<!-- I added an img class to the images for ease of use later -->

Everything is working fine, I just need some one to improve effect so that it could effect like moving from left to right, I tried with some effect, but it seems it required some css manipulation as well
Thanks
I modified your code to create a carousel where images are slid in and out. I accomplished this by animating the margin-left CSS property with jQuery. I specified a size for the .slider class and used overflow: hidden; to ensure the sliding images were not displayed outside of it.
If you wish, you can change the transition effect by changing the CSS property that is animated and ensuring that the elements are in the correct position for the animation before it begins.
You can also change the speed of the animation by changing the magic number 1000 that I've left in the calls to animate. This number is specified in milliseconds.
By the way, I should point out that while custom HTML attributes are allowed in HTML5 they should begin with data-; they are called data attributes.

I am firstly trying to fade in a div as soon as the page is loaded, then once its loaded I have 2 other divs on it that are acting like buttons. I would like to be able to click those 2 divs to be able to make other divs appear on top of the first one. Here is the code for the first div that should fade in a soon as the page is finished loading:
<div id="step1" style="visibility: hidden; display:block">
<a id="btn-step2-video" style="position:fixed; top: 45%; left: 25%;"><div class="btn-ad-choice ad-choice">
<br>
<p><b>Create a video ad:</b></p>
<video width="200" height="113" autoplay="autoplay" mute>
<source src="video/exemple.mp4" type="video/mp4">
Your browser does not support the video tag.
</video>
</div></a>
<a id="btn-step2-picture" style="position:fixed; top: 45%; right: 25%;"><div class="btn-ad-choice ad-choice">
<br>
<p><b>Create a picture ad:</b></p>
<img src="images/adexemple.jpg" alt="Exemple of a picutre ad" height="113" width="200">
</div></a>
</div>
and here is the code for the next divs that I would like to fad in if either of the 2 buttons is clicked. So if the button video is clicked the div containing the word video will fade in and the div containing the buttons will fade out, same for the second button with picture:
<div id="step2-video" class="box" style="visibility: hidden; background:#C0C0C0">
video
</div>
<div id="step2-picture" class="box" style="visibility: hidden; background:#C0C0C0">
picture
</div>
Finally here is the Javascript, however it does not work:
<script type="text/javascript">
var step1 = $('#step1'),
step2-video = $('#step2-video'),
step2-picture = $('#step2-picture'),
var boxes = $('.box');
$('#btn-step2-video').click(function(){
fade(step1, step2-video);
});
$('#btn-step2-picture').click(function(){
fade(step1, step2-picutre);
});*/
$(document).ready(function() {
$("#step1").fadeIn("quick");
});
function fade(thisIn, callback){
$(thisIn).fadeOut("slow");
$(callback).fadeIn("slow");
});
</script>
Thank you for your help ;)
Edited your original post, code is below.
Guess this is the functionality you want?
$(function() {
var step1 = $('#step1');
var step2video = $('#step2-video');
var step2picture = $('#step2-picture');
var boxes = $('.box');
step1.fadeIn("slow");
$('#btn-step2-video').click(function() {
fade(step1, step2video);
});
$('#btn-step2-picture').click(function() {
fade(step1, step2picture);
});
var fade = function(thisIn, callback){
$(thisIn).fadeOut("slow");
$(callback).fadeIn("slow");
}
