ive looked at other answers and none of them seemed to work which is why i decided to re-ask the question and show you guy my code so you can help me so here it is :
function searchForm() {
var body = document.getElementsByTagName('body')[0]
var search = document.getElementById('GIF-search').value;
var content = document.getElementById('content')
var xhr = $.get("http://api.giphy.com/v1/gifs/search?q=" + search + "&api_key=api");
xhr.done(function(data) {
var image = data;
var GIF = image['data'][0]['embed_url'];
var GIF_image = document.createElement('img');
GIF_image.setAttribute('src', GIF);
GIF_image.setAttribue('id', 'GIF');
content.appendChild(GIF_image)
});
}
var searchGIF = document.getElementById('search_GIF')
searchGIF.addEventListener('click', searchForm, false);

my problem here is that im getting a blank image on my site can anyone explain why this is happening and how i can fix it so it will actually show the GIF?
btw i know in the $.get("http://api.giphy.com/v1/gifs/search?q=" + search + "&api_key=api"); the apikey in not valid (this is on purpose);
Couple of things:
There was no jQuery in jsfiddle. Make sure you have it in your code.
Make https:// api call if your page is using https:// protocol.
setAttribute when you are setting id has got a typo. Look carefully.
URL you are getting at image['data'][0]['embed_url'] is not a image url but a webpage url. Try console log it and see. So you cant really set it as a src of some img tag. Find the correct image url and then proceed.

Try setting the class attribute this way
img.setAttribute("class", "YourClassName");
Then apply the style to YourClassName in a CSS file/style tag. (Might also want to call the script after you load the CSS) Like so
.YourClassName { /* style here */ }
Edit:
You can also check if the elements are rendered well (the HTML tags have the class names and onClick methods) using the console (press F12 on the page)
Hi I'm using this: http://galleria.io/ to create a popup image slider.
Basically I want it to appear fixed over my page only after the user clicks a link to open it (it will not open another page). If I use "display: none" it will load in the background slowing everything down as it will contain HD images.
Right now I am trying this:
<!DOCTYPE html>
<html>
<head>
<title>Testing</title>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
<script src="galleria/galleria-1.4.2.min.js"></script>
<style>
.galleria {
width: 700px;
height: 400px;
background: #000
}
</style>
<script>
</script>
</head>
<body>
Click me to load images
<script>
function showGallery() {
var content = "<div class=\'galleria\'><img data-src=\'photo1.jpg\'><img data-src=\'photo2.jpg\'><img data-src=\'photo3.jpg\'></div>";
var hello = "hello world";
console.log("hi it's working");
$('body').append(hello);
}
$('#imageshow').click(function() {
showGallery();
Galleria.loadTheme('galleria/themes/classic/galleria.classic.min.js');
Galleria.run('.galleria');
});
</script>
</body>
</html>
This the documentation for Galleria:
http://galleria.io/docs/getting_started/beginners_guide/
I had a real good look at this and even downloaded the galleria.js for it. Coming to the simple conclusion that your code is likely to only miss a document ready statement :
<script>
$(document).ready(function() {
function showGallery() {
var content = "<div class=\'galleria\'><img data-src=\'photo1.jpg\'><img data-src=\'photo2.jpg\'><img data-src=\'photo3.jpg\'></div>";
var hello = "hello world";
console.log("hi it's working");
$('body').append(hello);
}
$('#imageshow').click(function() {
showGallery();
Galleria.loadTheme('galleria/themes/classic/galleria.classic.min.js');
Galleria.run('.galleria');
});
});
</script>
I have successfully created an Ace editor before, but recently I am making a website called CodeProjects, and I want to put an Ace editor in. Whenever I try, it only shows the text function foo(items) {
var x = "All this is syntax highlighted";
return x;
}. On the page http://ace.c9.io/#nav=embedding&api=ace, it says you only need the code:
<!DOCTYPE html>
<html lang="en">
<head>
<title>ACE in Action</title>
<style type="text/css" media="screen">
#editor {
position: absolute;
top: 0;
right: 0;
bottom: 0;
left: 0;
}
</style>
</head>
<body>
<div id="editor">function foo(items) {
var x = "All this is syntax highlighted";
return x;
}
</div>
<script src="/ace-builds/src-noconflict/ace.js" type="text/javascript" charset="utf-8"></script>
<script>
var editor = ace.edit("editor");
editor.setTheme("ace/theme/monokai");
editor.getSession().setMode("ace/mode/javascript");
</script>
</body>
but when I try to embed it (or even just make the editor, not the site), again, it only shows function foo(items) { var x = "All this is syntax highlighted"; return x; }
Any suggestions?
it also says to copy files into your project. If you don't want to do that, include script from cdn
<script src="//cdn.jsdelivr.net/ace/1.1.01/min/ace.js"
type="text/javascript" charset="utf-8"></script>
see http://jsbin.com/ojijeb/165/edit
You need to put the content outside of the editor div [or fetch the content on page load using AJAX]. Either way, you then load the content into the editor with JavaScript: editor.setValue("hello world");.
To set the height of the editor, you resize the div it lives in, then call the editor's resize method.
var div = document.getElementById('editor');
div.style.height = some_multiple_of_the_line_height_for_tidiness;
editor.resize();
In my experience, you need to change div to pre. Just using pre instead of div in following way should solve your problem.
<pre id="editor" >
</pre>
I have anchors on a page that displays a different background image on mouse hover and mouse out. I have preloaded the images to avoid flickering and re-requesting the images from the server on mouse hover/out. The scripts works fine on IE8/FF but Chrome behaves differently. In the latest version of Chrome, the first time I hover on the anchor, the image is re-requested from the server causing a flicker, why is this? Succeeding mouse hover/out works fine and there is no flicker.
Code below:
<html>
<head>
<script src="http://code.jquery.com/jquery-1.8.3.min.js"></script>
<style type="text/css">
body:after
{
content: url('/images/1.png') url('/images/1a.png')
position: absolute;
top: -9999px;
left: -9999px;
}
.imageHover
{
display:inherit;
width:25px;
height:50px;
background:url('/images/1.png') no-repeat;
}
.imageOut
{
display:inherit;
width:25px;
height:50px;
background:url('/images/1a.png') no-repeat;
}
</style>
<script language="javascript" type="text/javascript">
var oneSelected = new Image();
var oneUnselected = new Image();
oneSelected.src="/images/1.png";
oneUnselected.src="/images/1a.png";
function OnImageMouseOver(target) {
$(target).toggleClass('imageHover', true);
$(target).toggleClass('imageOut', false);
}
function OnImageMouseOut(target) {
$(target).toggleClass('imageHover', false);
$(target).toggleClass('imageOut', true);
}
</script>
</head>
<body>
</body>
</html>
Converted anchor to image, but it still won't work in Chrome:
<html>
<head>
<script src="http://code.jquery.com/jquery-1.8.3.min.js"></script>
<script language="javascript" type="text/javascript">
if (document.images) {
var oneSelected = new Image();
var oneUnselected = new Image();
oneUnselected.src = '/images/1a.png';
oneSelected.src = '/images/1.png';
}
function OnRatingMouseOver(target, newSrc) {
$(target).attr('src', newSrc);
}
function OnRatingMouseOut(target, newSrc) {
$(target).attr('src', newSrc);
}
</script>
</head>
<body>
<div id="mainDiv" style="width:400px;">
<div id="inputDiv">
<table id="inputTable">
<tr>
<td>Rating</td>
<td>
<img id='rating1Anchor'
src='/images/1a.png'
onmouseover="OnRatingMouseOver(this, '/images/1.png');"
onmouseout="OnRatingMouseOut(this, '/images/1a.png');"
onclick="OnRatingClick(this, '/images/1.png', 1);">
</td>
</tr>
</table>
</div>
</div>
</body>

It may not be preloading them at all, as it's not displaying them it's just adding to the DOM? Try the following code to preload your images.
var preload = new Array();
function preload_image(){
for (var x = 0; x < preload_image.arguments.length; x++)
{
preload[x] = new Image();
preload[x].src = preload_image.arguments[x];
}
}
I have to say I very much doubt that the pngs are actually being rerequested from the server in Chrome. Can you post a screenshot of the Timeline in dev Tools showing the request going off twice? :) I think it's far more likely that you're just experiencing a slight hesitation during the repaint.
Is there a reason you aren't using image sprites? They are the canonical solution to this problem. The idea is simply that a single image is loaded that contains both the normal and "hover" or "active" states. The portion of the graphic shown gets swapped out using css "background-position". Here's a tutorial, and here's a table of support for "background-position" which goes all the way back to IE4.
Code should look something like this:
<html>
<head>
<style>
#myCoolLink {
background-image:url('img/image.gif');
background-position:0px 0px;
}
#myCoolLink:hover,
#myCoolLink.active {
background-position:0px -72px; //depending of course on the image
}
</style>
</head>
<body>
</body>
</html>
No script required, and it's much terser. The other great advantage of this is that you can still programmatically change the image over to the "hover" anytime you want by toggling the "active" class on the link, if you ever need to.
I'm trying to activate a CSS transition with Javascript through DOM when a div object is clicked. I avoided jQuery and used JS on purpose in order to learn DOM (this is actually my first experiment with it).
I implemented a standard solution: getting the elements' ListNode from the HTML document, then changing the className of the desired object. Yet, it does not seem to work properly
(I'm obviously using Firefox).
Thank you in advance.
Here are the files.
<!doctype html>
<html>
<head>
<link rel = stylesheet href = "style.css" type = "text/css" media = screen>
<script src = "script.js" type = "text/javascript"></script>
</head>
<body>
<div class = "image" onclick = "foo()"></div>
</body>
</html>
style.css
.transition {
-moz-transition: 2s width;
width: 150px;
height: 100px;
}
.image {
-moz-transition: 2s width;
width: 100px;
height: 100px;
background-color: black;
}
script.js
function foo() {
var k = document.getElementsByClassName("image");
k[0].className = "transition";
}
EDIT: Edited the code in order to make immediately visible the working solution.
You're using getElementsByName, but you don't have an element with a name of image, instead you have an element with a class of image. You probably intended to use document.getElementsByClassName('image'). On a side note, the structure of your html page is incomplete, you need a <head> and <body> section, also your <html> opening tag is in the wrong place.
<!doctype html>
<html>
<head>
<link rel = stylesheet href = "style.css" type = "text/css" media = screen>
<script src = "script.js" type = "text/javascript"></script>
</head>
<body>
<div class = "image" onclick = "foo()"></div>
</body>
</html>
Try this in your javascript logic:
function foo() {
var k = document.getElementsByClassName("image");
k[0].className = "transition";
}
As Stencil mentioned everything should be inside HTML Tag.Similar kind of width animation could be easily achieved using jQUery
$('.image').animate({width: 250}, 500 );
