how to get Element From an Iframe?
i want when the attribute of an element that its in a frame is true;
it show a text, and else show another text;
(sorry for bad english!)
like that:
<!DOCTYPE html>
<html>
<head>
<title>document</title>
</head>
<body>
<iframe id="frame" src="">
<!--we think in frame there is a span tag with button id-->
<span id="button" aria-passed="true">sss</span>
</iframe>
<br>
<!--if its true-->
<p id="content1" style="display:none;">
true
</p>
<!--if its false-->
<p id="content2" style="display:none;">
false
</p>
<!--now we want that, if aria-passed=true show content1 else content2.-->
<script type="text/javascript">
var Frame = document.getElementById('frame');
if(new RegExp ("true","gim").test(frame.contentWindow.document.getElementById('button').aria-passed="true") == true) {
document.getElementById('content1').style.display="block";
}
else {
document.getElementById('content2').style.display="block";
}
</script>
</body>
</html>
now i want to say why this code does not work????
any ideas?
It's much easier if you use jquery.
Example Code:
var elementattibutevalue = $("#frameID").contents().find("#htmlelementID").attr("SampleAttribute");
Hope it helps. (^_^)
I think the iframe in your code above is just a demonstration of how the loaded page code looks like?
Take a look at this post Javascript - Get element from within an iFrame.
Also change your 'Frame' variable to lowercase.

i tried this one : How can i remove all div's and other DOM HTML elements except a particular class using jQuery but not completing my target :

You can do it this way to remove everything but your wanted elements:
$(document).ready(function(){
var x = $('.exclude');
$('body').html(x);
});
Here is a sample:
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
var x = $('.exclude');
$('body').html(x);
});
</script>
</head>
<body>
<h1 class="exclude">Excluded heading</h1>
<p>I will disappear.</p>
<p class="exclude">I will remain in the page.</p>
<p class="exclude">Me Too!</p>
<p>Some text...</p>
<p>Some text...</p>
Some text...Some text...Some text...
</body>

How to load divs from page 2 into page 1 with JavaScript.
Page2.html
<html>
<head>
<title> title </title>
<body>
<div id="main">
<div id="content2"> this is content2</div>
<div id="content3"> this is content3</div>
</div>
</body>
</html>
I want to get and use the id content2 from page2 to create a div into page1 with the content of that div, after link was clicked and deleted, and do the same with content3, content4 and successively.
Page1.html
<html>
<head>
<title> title </title>
<body>
<div id="main">
<div id="content1"> this is content1</div>
get content
</div>
</body>
</html>
And then would be like that.
<html>
<head>
<title> title </title>
<body>
<div id="main">
<div id="content1"> this is content1</div>
<div>this is content2</div>
<div>this is content3</div>
</div>
</body>
</html>
I'm new in JavaScript and i have no ideia how to do that. If someone can help. Thanks.
Edited: I wanted a way to do it only with javascript and without jquery if that's really possible. I want my project working offline and I can't do that with jquery, because it doesn't work. I've downloaded jquery plugin and pasted it in my directory, but, didn't work, too.
You can use a combination of JavaScript, jQuery, and AJAX to accomplish this.
First, include the jQuery library:
<script src="//code.jquery.com/jquery-1.10.2.js"></script>
Then write a JavaScript function similar to this one which will replace your div element's html content with the Page2.html file:
var loadNewContent = function {
$.ajax("Page2.html", {
success: function(response) {
$("#content2").html(response);
}
});
};
And then you would need some 'trigger' to run this function such as this:
$("#content2").on('click', loadNewContent);
Hope this helps.
I wrote a small library called ViaJS using javascript & jquery. It basically lets you load content (like a div) from a source to the page. Check it out.
Via is a small library that allows you to load content on to a page dynamically
Hey guys I'm trying to get the following to work...
demo_test.txt to load into the "div1" container
only have a href id "test" to trigger it
<!DOCTYPE html>
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
<script>
$(document).ready(function() {
$("test").click(function() {
$("#div1").load("demo_test.txt");
});
});
</script>
</head>
<body>
<div id="div1">
<h2>Let jQuery AJAX Change This Text</h2>
</div>
<a id="test" href="#">Get External Content</a>
<br>
<a id="google" href="http://www.google.com/">Google</a>
</body>
</html>
Currently it doesn't run, but if I remove the Google line, it works. Is there something else I'm missing? Thanks!
Change your jQuery click handler to this:
$("#test").click(function() {
I've added a # in front of test to properly select your anchor tag.
<!DOCTYPE html>
<html>
<head>
<title> Cookie Clicker! </title>
<script type="text/javascript">
var logAt=function(id,message){
document.getElementById(id).innerHTML=message;
};
</script>
</head>
<body>
<h1> Cookie Clicker </h1>
<p> Keep collecting cookies and start your very own sweet empire!</p>
<p>
<div id="cookiesPerSecond"> </div>
<button type="button" onClick="getCookie()"><img src="http://thinkprogress.org/politics/2011/04/26/161276/penn-parents-cookies-cuts/" alt="Cookie"
style="width:304px;height:228px"></button>
<h3 id="cookies">Cookies:0 </h3>
</p>
<script type="text/javascript">
var cookies=0;
var cookiesPerSecond=0;
function getCookie(){
cookies+=1;
logAt("cookies","Cookies:"+cookies);
};
</script>
</body>
</html>
My image inside of the button is not displaying, and defaults to the "alt". I am programming this on notepad, and am opening it in chrome. What should I do to make it work?
What you linked is not a link to a direct image. You need to link directly to an image. This is the link you need to change:
<img src="http://thinkprogress.org/politics/2011/04/26/161276/penn-parents-cookies-cuts/"
Change it to this:
<img src="http://d35brb9zkkbdsd.cloudfront.net/wp-content/uploads/2011/04/cookie.gif"
Also, like User Roko C. Bulijan said, you need to use CSS to make it a background-image or it won't show up.
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);
