I'm very new to PHP and jquery, and am trying to set up an image gallery with thumbnails that when clicked, display a larger image in the div above them.
So far, I have this:
$(function() {
$('.thumbnail').click(function(e){
e.preventDefault();
$("#large").attr('src',"http://something.com/image.jpg");
});
});
What I want to do is change the image source to be from an array of images. When someone clicks thumbnail A, for instance, I want it to load the corresponding large image A into the div above the thumbnails. I have two arrays, one for the thumbnails and one for the larger images. Seems like a pretty basic thing to do, but like I said, I am totally new at this!
Thanks!
Your javascript code looks correct. Can I see your html code.
<html>
<head>
<title>Test</title>
<script src="http://code.jquery.com/jquery-2.0.3.min.js"></script>
</head>
<body>
<div id="container">
<img id="large" src="" />
</div>
<div id="thumbnail-container">
<img class="thumbnail" src="large.PNG" width="50" height="50" alt="test1"/>
<img class="thumbnail" src="large2.PNG" width="50" height="50" alt="test2"/>
</div>
<script>
$(function() {
$('.thumbnail').click(function(e){
e.preventDefault();
$("#large").attr('src',$(this).attr('[REPLACE_WITH_YOUR_LARGE]'));
});
});
</script>
</body>
</html>
And I simply use your js code on the sample above.
You need to pass the array to your javascript first, store in a javascript array, and with proper index (javascript only accept number index), and load it with click event.
there is two way(from my knowledge) to do this.
1) At ur index page, after you load your JS file, you echo <script>loading_function("array_in_string")</script>;, and process the string in JS and store into array.
2) using Ajax, call to server and request for the full list.
In the HTML of the thumbnail images, add a data-tag such as
<img src="image.jpg" data-full-imgpath="http://..." class="thumbnail" />
<img src="image2.jpg" data-full-imgpath="http://..." class="thumbnail" />
Then change your JS to this:
$(function() {
$('.thumbnail').click(function(e){
e.preventDefault();
var imgPath = $(this).data("full-imgpath");
$("#large").attr('src',imgPath);
});
});

Is there a way to fetch the content of a div and place that ocntent in the 'src' parameter of an image? I'm working on a project that uses json to load translation files, and tehrefore I can't load an image directly, but figured I could at least load the image name.
So:
<div id="flag-name" style="hidden">en-flag.jpg</div>
<img src="DIV CONTENTS HERE">
Ideas appreciated! (Am also using jquery so open to that as well)
The button demonstrates that ablility. Use the button's onclick code wherever you need.
<div id="flag-name" style="hidden">en-flag.jpg</div>
<img id="myImage" />
<button onclick="document.getElementById('myImage').src=document.getElementById('flag-name').innerText">Change</button>
You can simply do it in jQuery by getting the text of the div and then setting the source of image like this:
var source = $("#flag-name").text();
console.log("before - " + $("#image").attr("src"));
$("#image").attr("src",source);
console.log("after - " + $("#image").attr("src"));
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="flag-name" style="hidden">en-flag.jpg</div>
<img id="image" src="DIV CONTENTS HERE">
You need an event to start the jQuery/javascript -- so I added a button. Also, you will find it easier to target specific DIV and IMG tags if you give them IDs or classes.
$('button').click(function(){
var mySrc = $('#flag-name').text();
$('img').attr('src', mySrc);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="flag-name" style="hidden">http://placeimg.com/300/200/animals</div>
<img src="DIV CONTENTS HERE">
<button>Go</button>
I am trying to set the image source of an image object with javascript.
I have tried
<img src="" id="image" alt="">
<p id="change">Change</p>
$("#change").click(function () {
$("#image").attr("src", "some source");
});
The problem is that it seems it does change the src, but it doesn't work if the image wasn't loaded when the page loaded. So I cannot suddenly change to the logo of Stackoverflow. Can this be true? How can I then load the image while changing the source?
I had an issue similar to this a couple weeks ago, the easiest way I managed to solve the issue was by loading all image's you will need, and set all of the ones you don't need right away as hidden. Then when your action that causes the change is triggered, you can change the image visibility on the one you want to disappear and the one you want to be shown.
If you have bootstrap installed, it is as easy as adding and removing a class via jQuery
HTML
<img src="" id="image1" alt="">
<img src="" id="image2" alt="" class="hidden">
<p id="change">Change</p>
Javascript
$("#change").click(function () {
$('#image1').addClass('hidden');
$('#image2').removeClass('hidden');
});
I am working on a website that needs to use javascript. I need the Javascript to use an external page. I don't quite understand how to do this. I have 5 files on my computer that needs to be able to replace an image file's name and alt. I cant use an http though.
I have the code for an image:
<img src="images/cablecar.jpg" width="480" height="270" alt="cable car turnaround" id="gallery" />
I need use javascript to change the cablecare and alt part to a new image file and description while using onmouseover.
The code I have so far is
Javascript:
function switchPix(file, desc){
var line = '<img src= asian.jpg width=\'480\' height=\'270\' alt= +desc+/>';
document.getElementById("pix").write(line);
}
html:
<figure id="pix" class="right">
<script src="scripts/gallery.js">
</script>
<img src="images/cablecar.jpg" width="480" height="270" alt="cable car turnaround" id="gallery" />
</figure>
<ul>
<li>Asian Art Museum</li>
I have to use the word file to replace cablecar with asian so the file name is asian.jpg
at the end the code is suppose to change the image on the page to another image when the mouse is put over one of five links.
Sorry if this is a bit confusing I really am having trouble understanding it myself and wasn't given nearly enough information to understand how to do it myself.
Hi try to use this code
<figure id="pix" class="right">
<script src="scripts/gallery.js">
</script>
<img src="images/cablecar.jpg" width="480" height="270" alt="cable car turnaround" id="gallery" />
</figure>
<ul>
<!-- fix onmouseover (all small case) and string parameters -->
<li>Asian Art Museum</li>
and the javascript code like this work
function switchPix(file, desc) {
var $elm = document.getElementById("gallery");
$elm.src = file;
$elm.alt = desc;
}
Sorry to sound naive since I'm a beginner. I have been trying to load an image on my website with the image hosted somewhere else online and having a url "http://www.vapor-rage.com/wp-content/uploads/2014/05/sample.jpg"
I have an image tag defined as below
<img id="image" src="" alt="" />
Moreover my javascript function executes the following on a button click
document.getElementById("image").src="http://www.vapor-rage.com/wp-content/uploads/2014/05/sample.jpg";
The URL seems to work fine, but the image doesn't show up onclick.
Am I making any mistake?
Thanks for any suggestion :)
I could see that you are using " inside here, may be the HTML would also have " so that, it might not work. You can use the following code:
<a href="#"
onclick='document.getElementById("image").src="http://www.vapor-rage.com/wp-content/uploads/2014/05/sample.jpg"; return false'>Change</a>
I created a Jsfiddle, and it seems to work fine.
https://jsfiddle.net/ltlombardi/jvts4m3y/
var coco = function(){
document.getElementById("image").src="http://www.vapor-rage.com/wp-content/uploads/2016/02/Vapor-Rage-Small-Logo-new.png";
};
<img id="image" src="" alt="" />

My CMS's lightbox-style photo gallery outputs code like below. I've provided code for two thumbnails.
The parameter values for "m" and "s" will always be "150" and "true." I'd like to change that to m=250 and s=false.
I'm new to JavaScript and jQuery. If you have a suggestion, please help me out with where to put the code on the page. Thank you.
<div class="thumbTight MainContent">
<div class="thumbContents">
<a href="/PhotoGallery/banana.jpg" rel="lightbox[2065379]" title="Banana">
<img src="/ResizeImage.aspx?img=/PhotoGallery/banana.jpg&m=150&s=true" alt="Banana" />
</a>
<div class="description" style="display: none;"></div>
</div>
</div>
<div class="thumbTight">
<div class="thumbContents">
<a href="/PhotoGallery/cantaloupe.jpg" rel="lightbox[2065379]" title="Cantaloupe">
<img src="/ResizeImage.aspx?img=/PhotoGallery/cantaloupe.jpg&m=150&s=true" alt="Cantaloupe" />
</a>
<div class="description" style="display: none;"></div>
</div>
</div>
In your document ready handler, use each to iterate over the thumbnails (images inside divs with the thumbContents class) and assign the src attribute to the original src attribute with the required substitutions.
$(function() {
$('.thumbContents img').each( function() {
var $img = $(this);
$img.attr('src', $img.attr('src').replace(/m=150/,'m=250').replace(/s=true/,'s=false') );
});
});
You can run this jQuery after the page has loaded. The images will start loading with the different URL, your code will run and change the image URLs and then the new one will load and display. There is nothing you can do client-side to prevent the initial display unless you actually use CSS such that they images are initially hidden and only made visible AFTER you've set the desired URL.
$(".thumbTight img").each(function() {
this.src = this.src.replace(/m=150/, "m=250").replace(/s=true/, "s=false");
});
