Loading code from a different html file - javascript

I have a website with a news feed that I updated regularly. The problem is that when I update it I have to change the code in every page. This wouldn't be a problem if the website was small, but it has about 20 pages
I want to know if there is any way for me to just have a separate html file with just the newsfeed, that I would load on the other pages.

Using jQuery and making an AJAX call would be one solution to your problem, although it's a bit excessive.
<html>
<head>
<script>
$(document).ready(function() {
$.ajax({
url: "news.html",
cache: false
}).done(function(news) {
$("#news").html(news);
});
});
</script>
</head>
<body>
<div id="news">
</div>
</body>
</html>
Another solution would be to simply use an iFrame.
<html>
<head>
</head>
<body>
<div id="news">
<iframe src="news.html"></iframe>
</div>
</body>
</html>

Need to understand JQuery load on click on a link flow and mistakes in my code

I am trying to make my 10 pages static website dynamic so that everytime i don't need to design every page as the same home page. I have tried few jquery statements to load data into div on click of a link.
I have tried the following code and it didn't work:
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
<script>
$(document).ready(function() {
$("button").click(function() {
$("#div1").load("demo.txt");
});
$("#link").click(function() {
$("#div1").load("demo.txt");
});
});
</script>
</head>
<body>
<div id="div1">
<h2>Let jQuery AJAX Change This Text</h2></div>
<button>Get External Content</button>
<br>
<br> click here </body>
</html>
I have got this from W3School's online Tryit editer. It works fine there but not in my local webpage on my machine. Can I get an explanation what is happening and what I am missing. Thanks.

Get content from another page with JavaScript

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

how to get content of div in a html from another html

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);

JavaScript code in iframe

I need to run JavaScript code in iframe. But script with id "us" loaded after creating iframe. How to run this javascript in iframe?
<iframe id="preview">
#document
<html>
<head>
<script src="http://code.jquery.com/jquery-latest.min.js"></script>
<script id="us" type="text/javascript">
$("#preview").ready(function() {
$(".test").click(function() {
alert(true);
});
});
</script>
</head>
<body>
<style></style>
<div class="test"></div>
</body>
</html>
</iframe>
Thanks in advance.
The IFrame has no access to what's outside of it. Everything inside IFrame is separate page ergo you threat it like so. So you do your document.ready in it.
Example: http://jsfiddle.net/ZTJUB/
// Since this is page you wait until it's loaded
$(function() {
$(".test").click(function() {
alert(true);
});
});
The jQuery instance inside of the iFrame doesn't know it's supposed to be traversing the parent DOM, so therefore it won't know where to look for an element with the id "preview"
As per my comments above, you should attach to the iframe's document.ready, like this:
// Since this is page you wait until it's loaded
$(document).ready(function() {
$(".test").click(function() {
alert(true);
});
});
EDIT:
Just realizing you are probably having an entirely different issue here - Html code as IFRAME source rather than a URL - if you are trying to embed the iframe code inline, you are going to have problems. Take the following code for example:
<html>
<head></head>
<body>
Some stuff here
<iframe id="preview">
<html>
<head>
<script src="http://code.jquery.com/jquery-latest.min.js"></script>
<script id="us" type="text/javascript">
$(document).ready(function() {
$(".test").click(function() {
alert(true);
});
});
</script>
</head>
<body>
<style></style>
<div class="test">test</div>
</body>
</html>
</iframe>
</body>
</html>
if you render that page in firefox, and then inspect the source in firebug, you'll see:
<html>
<head></head>
<body>
Some stuff here
<iframe id="preview">
<html>
<head></head>
<body></body>
</html>
</iframe>
</body>
</html>
This is happening because the browser isn't expecting to see the code inline between the iframe tags.
Since you're not addressing the questions in the comments to better clarify what you are trying to do... I shall assume you are trying to access content IN your iframe FROM your parent page. Since the other answer should work fine if trying to run it from within the iframe.
On the parent page try something like:
$(function() {
$("#preview").load(function ()
$("#preview").contents().find(".test").click(function() {alert(true);});
});
});
*This assumes both parent and iframe are on the same domain.

site-onload-gif within php

problem is, that the website is loading like for about 20 second or longer (user-problems preprogrammed)
my solution was to load a pre-site where the user sees a loading screen.
i did this with this html-site but i want to do the same in php.
the test-page is http://kater.selfhost.me/test/
Source Code:
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title></title>
<script type="text/javascript">
window.onload = function() {
document.getElementById("siteLoader").style.display = "none";
document.getElementById("container").style.display = "block";
}
</script>
</head>
<body>
<div id="container" style="display:none">
<div id="body">
<iframe src="http://kater.selfhost.me/stats/skins.php" frameborder="0" height="2000px" width="1024px"></iframe>
</div>
</div>
<div id='siteLoader'>
<div id='siteDetailLoader'>
<img src='ajax_loader.gif' border='0'>
Please wait while the page loads...<br /> <br />
</div>
</div>
</body>
</html>
i tried some workarounds, but after searching & testing for about three hours i give up...
thanks in advance for any help provided! :-D
Adding what I alredy said at your question commentary, I made a code loading this content via AJAX:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<script type="text/javascript">
$( document ).ready(function() {
//Load content
loadAjaxContent();
});
function loadAjaxContent()
{
//VERY IMPORTANT: the URL domain MUST HAVE be the same as your request
//that's why I'm not writting the full http://kater.selfhost.me/stats/skins.php
$.ajax({
url: "/stats/skins.php"
}).done(function(data) {
//remove loader
$("#siteLoader").hide();
//put PHP content
$("#ajaxContent").html(data);
});
}
</script>
</head>
<body>
<div id="body">
<div id="ajaxContent" style="width:1024px;"></div>
<div id='siteLoader'>
<div id='siteDetailLoader'>
<img src='ajax_loader.gif' border='0' />
Please wait while the page loads...<br /> <br />
</div>
</div>
This is the most used way to load asynchronous content in the web. But pay attention at this: The http://kater.selfhost.me/stats/skins.php page is made to open as single page in the web, so it has <html> , <head>, <body> , etc.. tags, so..after loading this page into another you'll have two <html>, <body> .. tags in a same page, this is bad, but modern browsers have an awesome common sense and don't bother by this, but you should know that, and be aware.
The actual problem why it isn't loading yet, is this javascript in your content:
<script type="text/javascript"><!--
EXref="";top.document.referrer?EXref=top.document.referrer:EXref=document.referrer;//-->
</script>
I removed that and now works fine. Remember that's a quick fix, I don't know what this JS does.
Why it works in <iframe> and doesn't via AJAX? When you open in <iframe> is like opening in a new browser window..and via AJAX, as I have said, it'll load the page content straight inside your "parent" page.
So, removing this Javascript will work, but awesome further solutions:
If you need to open this page both as content to load (via AJAX), both as single page, you can make two pages.. one for each need.
If you just want to use as content to load, remove <html>, <head>, etc.. tags, and fix Javascript to work inside another page.
