Let's say there is page A, that has an iframe that contains page B and page B includes another iframe containing page C.
Can an event be fired from page C in a way that it traverses upwards and is received by both pages A and B?
Basically, is there a solution other than going to parent windows one by one and calling contentWindow.postMessage on each one? Is there a more concise way?
Try something like this so both page will be a part of single DOM
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
$('#B').load("B.html");
$('#C').load("C.html");
});
</script>
</head>
<body>
<div class='parent'>
<div id="A"></div>
<div id="B"></div>
</div>
</body>
</html>

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
my parent jsp contains two div..
<html>
<script src="a.js"/>
<body>
<div id="child1"></div>
<div id="child2"></div>
</body>
</html>
my child page is
<html>
<body>
child_1
</body>
</html>
using ajax call i am loading child page into my parent div and want to use the same js file in child page loaded by parent page by referring it using any method and not by manually including it on child page,So please anyone help me with this i am in big trouble because of this.
In ajax call:
$.get('/home',
{script:'resolvedJSLink'},
function(){$('#child1').html(data);}
);
And in child1.jsp:
<html>
<script src='<%= request.getParameter("script") %>'/>
<body>
child_1
</body>
</html>
Maybe another solution for this case is load script dynamically: http://www.javascriptkit.com/javatutors/loadjavascriptcss.shtml
I’ve got an HTML fragment like <p>Hello, World!</p> and want to attach it to the container HTML page that includes
<script src="lib/kotlin.js"></script>
<script src="my-app.js"></script>
There are two package that came to my mind:
kotlin.js.dom.html.window.document.*
kotlin.browser.document.*
Which should I use and how do I access the document’s root? I’ve already tried document.getElementById("container") whereby container is the id of a DIV. But this returns null. I also tried document.appendChild(node)...
Also which of the above packages should I prefer?
I just figured out that the JS output of the compiled app needs to be below the element that is referenced inside the app.
I’ve created a demo case that illustrates this:
<!DOCTYPE html>
<meta charset="utf-8"/>
<script src="lib/kotlin.js"></script>
<p>Look inside the JavaScript Console of your browser…</p>
<div id="container"></div>
<script>
console.log("Native JavaScript");
</script>
<!-- This script tag was misplaced. It needs to be placed after all elements you want to access in your DOM -->
<script src="kotlin-javascript-hello-world.js"></script>
page1.html
<!DOCTYPE html>
<html>
<head>
<script src="common_script.js"></script>
</head>
<body onload="init()">
<h1>My First Page</h1>
<p id="demo">This is a paragraph.</p>
</body>
</html>
page2.html
<!DOCTYPE html>
<html>
<head>
<script src="common_script.js"></script>
</head>
<body>
<h1>My second Page</h1>
<div id="nextpageId">I want to access my div</div>
</body>
</html>
common_script.js
function init() {
alert($("#nextpageId").text());
}
In the following code I have two pages i.e. page1.html & page2.html and these contain the common JavaScript file.
My problem is to access page2.html div#id when page1.html is loading.
use this in your javascript
$('body').attr('unique_id')
and give unique id for your page in body tag
<body id='unique_id'>
or you can also pass in url
or use this code
function init() {
alert( $('div').attr('id') == "nextpageId" )
}
You don't explicitly state that you are using jQuery Mobile but you have tagged your question as such and are using PhoneGap so I will assume so...
Your pages don't conform to a standard jQuery Mobile layout. They are missing the required data-roles. Specifically data-role="page" along with child data-role="content" declarations.
http://jquerymobile.com/demos/1.2.0/docs/pages/page-anatomy.html
Your second page will be loaded via Ajax and the <script> tag on the second page will be ignored. In fact, only the contents of the nested <div data-role="page"> section will be loaded.
To pull that markup, you can simply access the <div> given its ID and that ID should be unique. You can use the pageinit or pageshow events to control your timing on the Ajax load.

I am currently embedding a third-party javascript file directly on my page.
However, the website I'm embedding it from takes a while to respond so it stops the rendering of my site for several seconds.
I'm currently embedding it on my page on the spot where it will write some values:
<script language="javascript" type="text/javascript" src="[third-party site/file.js]"></script>
The response from the embedded script is just some JavaScript:
document.write('<div class="value">Value 1</div><div class="value">Value 2</div>');
I was thinking that after the page loads use jQuery to make an AJAX request and somehow parsing the response so I can get the values I need.
Is there be a better approach?
You can place this script inside a hidden element on the end of the body (just before </body>) and, after the page has loaded, move it to the desired location with jQuery.
<div id="hiddenElement">
<script type="text/javascript" src="[third-party site/file.js]"></script>
</div>
<script type="text/javascript">
$(document).ready(function() {
$("#hiddenElement").appendTo("#someOtherElement");
});
</script>
</body>
Another solution would be to use jQuery .getScript() to load the script in the desired location as you said and #James McDonnell said.
$(document).read(function()
{
$.getScript(/* src */)
});
This will run after the page has loaded.
$.getScript()
Perhaps this could be part of your solution. Here is a stand-alone jQuery example where a button is used to trigger a change event on a DIV. This example just shows you how to access the html content of the div and to see how to manipulate/change it. This is not a solution for you but parts of it might be useful when combined with rcdmk's and James' ideas.
<html>
<head>
<!--<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>-->
<script src="http://code.jquery.com/jquery-latest.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$('#button_test').click(function() {
$('.value').html('New stuff').change();
});
$('.value').change(function(){
$('div').each(function() {
alert($(this).html());
});
});
});
</script>
</head>
<body>
<div class="value">Value 1</div>
<div class="value">Value 2</div>
<button id="button_test">Click me</button>
