How to use Javascript/jQuery to load the content from another domain?
Question
I need to create a javascript application that can display the content from another domain (admittedly another big website). Further interpretation of the DOM tree is not needed at the moment. It will be used by only ten more people.
I can make it work via php's get_content function. But that is very slow since it runs on the server side. I looked into any origin but cannot get it to work. It is best to not touch any origin since we use it extensively and we don't have much cash to spend around. Can anyone help? By the way, iframe is not an option since the big website blocked it. The code is below. Admittedly I kind of took it from another stackoverflow answer. Thank you in advance!
Btw. another engineer told me if I use the extension .hta instead of html, the same-origin policy issue would be resolved. I tried it and it did not work. But I was wondering if I did it right.
<html>
<head>
<script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
<script>
function myCallbackFunction(myData) {
$(function() {
$("#test").contents().find('html').html(myData.contents);
});
}
</script>
<script src="http://anyorigin.com/get?url=http://http://www.amazon.com/dp/B001F7SGHQ/&callback=myCallbackFunction"></script>
</head>
<body>
</body>
<iframe id='test' style='width: 100%; height: 100%'>
</html>

Try something like the following.
var invocation = new XMLHttpRequest();
var url = 'http://http://www.amazon.com/dp/B001F7SGHQ/&callback=myCallbackFunction';
function callOtherDomain() {
if(invocation) {
invocation.open('GET', url, true);
invocation.withCredentials = true;
invocation.onreadystatechange = handler;
invocation.send();
}
}
Addition of [withCredentials = true] will enable the HTTP header "Access-Control-Allow-Origin:".

there's another good solution might be what you need via PHP , is to use class called PHP
Simple HTML DOM Parser
this class can copy all source of a websites and you can save it in your server with extension you want also you can modified what you need before you save and this class have a full documentation (You need to be good in PHP5 POO ) this a link for class
http://simplehtmldom.sourceforge.net/
and there a good advanced thing you can do it for make your website faster , is use a Cash System so you can download the source from website one time a Day or 1H or 12 Hours , and save it in your host . i hope that will give you what you need .
