How can I write client javascript to get an image by its source ?
An image that is on the page?
You can do this with jQuery:
<body>
<!-- your content including the image -->
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js"></script>
<script type="text/javascript">
$(function() {
var myimg = $('img[src="/some/path/to/img.jpg"]');
});
</script>
</body>
This uses the tag-selector(docs) along with the attribute-equals-selector(docs) to get img elements where the src matches the source you want.
Use JQuery.
$("img[src='imageurl.jpg']")

I have a small nw.js app that alters the div section of the index.html page:
var myDiv = document.getElementById("outputSection");
var myImg = document.createElement("img");
myDiv.appendChild(myImg);
myImg.src = 'http://127.0.0.2:8080/prime_almost_full_00007.0001.png';
myImg.width = '256';
myImg.height = '256';
myImg.class = 'reel';
myImg.id = 'image';
myImg.setAttribute("data-images", 'http://127.0.0.2:8080/prime_almost_full_00007.####.png|0001..0250');
The HTML code I'm trying to mimic in my static example, which works, is:
<img src='http://127.0.0.2:8080/prime_almost_full_00007.0001.png'width='256' height='256' class='reel' id='image' data-images='http://127.0.0.2:8080/prime_almost_full_00007.####.png|0001..0021'>
I'm using the Jquery-reels library. At the top of my page, I include it thusly:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
<script src='http://code.vostrel.cz/jquery.reel.js' type='text/javascript'></script>
For some reason, while the image shows up with the first code snipped, it isn't interactive. My static page, which works is like this:
<!DOCTYPE html>
<html>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
<script src='http://code.vostrel.cz/jquery.reel.js' type='text/javascript'></script>
<head>
<title>Hi there</title>
</head>
<body>
<div>
<img src='http://127.0.0.2:8080/prime_almost_full_00007.0001.png'
width='256'
height='256'
class='reel'
id='image'
data-images='http://127.0.0.2:8080/prime_almost_full_00007.####.png|0001..0021'>
</div>
</body>
</html>
It's not clear to me why this is happening. Is it something about node-webkit?
EDIT: re-scanning doesn't seem to work:
myDiv.innerHTML = "<img src='http://127.0.0.2:8080/prime_almost_full_00007.0001.png' width='256' height='256' class='reel' id='image' data-images='http://127.0.0.2:8080/prime_almost_full_00007.####.png|0001..0021'>";
$.reel.scan();
When the page loads, the reel plugin automatically looks for elements with the attribute class="reel". See the annotated source for more info about this.
According to that documentation, since you are adding an element to the page after the page loads, you may need to call the $.reel.scan() function at the end of your javascript.
I am using prettyPhoto inside a Movable Type CMS page. To make it work I have to use a
<p>
<mt:setvarblock name="html_head" append="1">
JS scripts here
</mt:include>
</p>
section. To make a gallery with 30-40 pictures, I have to add a block for each picture that looks something like this:
<a href="pathtoimage.jpg" rel="prettyPhoto[GalleryName]" title="Some title">
<img src="pathtothumbnail.jpg" alt="alt text" height="120" width="120" />
</a>
I want to generate these entries from a csv file using a (python) script and put into a separate file on the web server. Then I use this code to load these entries into the page:
<div id="divTestArea1"></div>
<script type="text/javascript">
$(function() {
$("#divTestArea1").load("output_en.txt");
});
</script>
When I load the page the thumbnails show up, but when I click them the pathtoimage.jpg is loaded instead of prettyphoto.
My question: Am I doing something wrong or is movable type blocking the execution for security reasons? How to debug this? I have firebug but no idea what to look for.
P.S: When pasting the entries directly into the page it works as expected.
Edit: full working code
<p>
<mt:setvarblock name="html_head" append="1">
<script src="../gallery/js/jquery-1.6.1.min.js" type="text/javascript"></script>
<link rel="stylesheet" href="../gallery/css/prettyPhoto.css" type="text/css" media="screen" charset="utf-8" />
<script src="../gallery/js/jquery.prettyPhoto.js" type="text/javascript" charset="utf-8"></script>
</mt:setvarblock>
<mt:include name="include/header.tmpl">
<div id="divTestArea1"></div>
<script type="text/javascript">
$(function() {
<!--$("#divTestArea1").load("../gallery/output_en.txt");-->
$("#divTestArea1").load("../gallery/output_en.txt", function() {
$("a[rel^='prettyPhoto']").prettyPhoto();
});
});
</script>
<script type="text/javascript" charset="utf-8">// <![CDATA[
$(document).ready(function(){
$("a[rel^='prettyPhoto']").prettyPhoto({social_tools: false});
});
// ]]></script>
</mt:include>
</p>
Try including the prettyPhoto() call after the AJAX has finished loading, because at the moment the plugin is being executed on page load, before the element it is targeting is available in the DOM.
<script type="text/javascript">
$(function() {
$("#divTestArea1").load("../gallery/output_en.txt", function() {
$("a[rel^='prettyPhoto']").prettyPhoto();
});
});
</script>
I have two html file
a.html
<html>
<head>
<script type="text/javascript" src="jquery.js"></script>
</head>
<body>
<div id="content">
hello every one
</div>
</body>
</html>
and another page
<html>
<head>
<script type="text/javascript" src="jquery.js"></script>
</head>
<body>
<div id="result">
</div>
<iframe id="ifr" src="http://example.com/a.html">
</iframe>
<script type="text/javascript">
divv = $('#ifr').contents().find('div#content').clone();
$('#result').html(divv.html());
</script>
</body>
</html>
In second one I try to get first html and get contet div in it.after that I put this value to result div .
but It's not work. How can I do that.
You do not need to use an iframe; you can use ajax to do that. It's very straight forward.
$(function() {
$('#result').load('a.html #content',function()
$(this).html( $('#content').html() );
});
});
EDIT
As evident from comments below, scope of question has changed. The two pages are on different domains without CORS. Therefore the above answer would not work.
In order to use ajax, you may want to create a server-side script to act as a proxy. Then you'll call that script on your server and it will fetch the a.html page for you.
I guess that could be the right way.
var ifr = document.querySelector('#ifr');
var html = ifr.contentDocument.querySelector('div#content').innerHTML;
$('#result').html(html);
i am new to jquery, can anyone tell me how to display and image using external jquery in my html file.
i want my html to be clean and load the image where the image path is mentioned in the external jquery file.
my jquery file will be like this testjquery.js
// url to load the image (which i dont know ,whats the code for it)
and in my html file.
<html>
<head>
<script type="text/javascript">
(function() {
var test = document.createElement('script');
test.type = 'text/javascript';
test.async = true;
test.src = 'testquery.js';
var s = document.getElementsByTagName('script')[0];
s.parentNode.insertBefore(test, s);
test.onload=function(){
// function to load the external image
}
})();
</script>
</head>
<body>
</body>
</html>
Thanks in advance!
You can simply use:
HTML
<div id="divWhereYouWantAddImage"></div>
JQUERY
$('#divWhereYouWantAddImage').append("<img src='img.jpg' />");
You can read more about jquery .append() function here.
i think your question is wrong
so test this
first sure Loaded Jquery script file
and Set html for div Element
<div id="imageContainer"></div>
<script>
$('#imageContainer').html('<img src="/images/test.jpg" />');
</script>
Below is the file content in ExternalJSFile.js
imageUrl = 'your/img/path.png';
Your html file
<html>
</html>
<script src="ExternalJSFile.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function(){
alert(imageUrl);
});
</script>
I dont know exactly what you mean... but i guess you mean obtrusive jQuery. So your html stays clean. The javascript you can put it in an external file or at the bottom of your page. If you put it in an external file you can delete the script tags.
<html>
<head>
<script src="style.js" type="text/javascript"></script>
</head>
<body>
<div id="image"></div>
</body>
</html>
and in style.js (you can put it in the same directory)
$(document).ready(function(){
imagePath = 'your_image.png';
$('#image').html("<img src='" + imagePath + "' />")
});
You can use html or append. The html function clears the whole image div and replaces it with the image. The append, appends it to the div so you can add another one later. The (document).ready function will run after the whole document is loaded.
I cant make the shadowbox work...I have a static html page which has an image that acts as a link to open a swf in the shadowbox.
however when I click on the image it opens the swf like any other image file in the browser.
The Shadow box doesn't seem to work at all.
This is my html page. I am using shadowbox-build-3.0b. Its strange that this editor doesnt allow new users to use image tag in the html code in the editor. So i have changed mine to image.
<html>
<head>
<script type="text/javascript" src="js/jquery.js"></script>
<script type="text/javascript" src="shadowbox-build-3.0b/adapters/shadowbox-jquery.js"></script>
<script type="text/javascript" src="shadowbox-build-3.0b/shadowbox.js"></script>
<link type="text/css" href="shadowbox-build-3.0b/shadowbox.css" rel="stylesheet" media="screen">
<script type="text/javascript" src="shadowbox-build-3.0b/languages/shadowbox-en.js"></script>
<!-- Begin Shadowbox JS -->
<script type="text/javascript">
jQuery(document).ready(function () {
Shadowbox.init({
language: "en",
players: ["image"]
});
});
</script>
<!-- End Shadowbox JS -->
</head>
<body>
<image src="imagewithplaybutton.jpg" >
</body>
</html>
Hmm. I have not used shadowbox myself, but if you look at the way how the page suggests you set shadowbox up, there seems to be things that are wrong.
As i understand you want swf file to open when clicking on image; Shouldn't you set players: to swf then?
Your code also does not show if your img has link around it and if that link has rel="shadowbox" attribute.
I guess it should be set up something like this:
<script type="text/javascript">
Shadowbox.init({
language: "en",
players: ["swf"]
});
</script>
<img alrt="click here to open swf file" src="imgofflash.jpg"/>
Shadowbox.init() shouldn't be in the document.ready(). It should execute as the page loads.
