Get HTML of another page in another domain using JavaScript

Right now, I am using curl in PHP to get the HTML source code of some remote web page.

Is there any way I can get the same HTML source code of s开发者_开发问答ome cross-domain web page in JavaScript? Any tutorials?

I think you need to know about JSONP to access cross-domain web pages in js

Q. How is this any different than issuing an AJAX "GET http://otherdomain.com/page.html" call?

A. The same-origin policy checks the HTTP response headers for AJAX requests to remote domains, and if they don't contain a suitable Access-Control-Allow-Origin header, the request fails.

So, there are two ways to make this work:

• If you control the other domain, you can include the following header in the HTTP response:

  Access-Control-Allow-Origin: *
  (details at MDC)

• If you don't, you're stuck implementing a server-side proxy (for example, this simple PHP proxy).

In any case, once you implement one of the two options above, you're left with a simple AJAX call:

$.ajax({
  url: "http://mydomain.com/path/to/proxy.php?url="+
        encodeURI("http://otherdomain.com/page.html"),
  dataType: "text",
  success: function(result) {
    $("#result").text(result);
  }
});

This solution I just found might be of use like the other workarounds...
