I want to use JavaScript to make a simple http get.
I used jQuery to perform my request. My code runs on IE8.0 but not in Chrome (ver 6.0).
My page has the following code: (to simplify, i made a simple request to a html page, but my needs is other)

 <!DOCTYPE html PUBLIC "-//IETF//DTD HTML 2.0//EN"> 
   <html> 
       <script type"text/javascript"    src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> 
    <SCRIPT TYPE="text/javascript"  >

    function sendGet(){
        $.get(
            "http://www.google.pt",
            function(data) {
               alert('page content: ' + data);
        });
    }
    </SCRIPT>
    <head> 
        <title> Http Get Demonstration </title> 
    </head> 
    <body> 
        <p/>
        <input type="button" value="Http Get" onclick="sendGet();" />   
    </body> 
   </html>

As i said, when i load this page on IE and press the button, i get the alert with the html code. But in Chrome the alert appears with empty text (null?). In Chrome Console from “Developer tools” i get the message: “XMLHttpRequest cannot load http://www.google.pt/. Origin null is not allowed by Access-Control-Allow-Origin.”

Anyone can explain me what’s the meaning of this message? And what i should change to my page run in Chrome?

Thanks

    Due to same origin policy you cannot send AJAX requests to different domains than the one hosting your page. So unless your page is hosted on http://google.pt you cannot send an AJAX request to this domain. One possible workaround is to setup a server side script on your domain which will act as bridge between google.pt and the client or use JSONP if the distant domain supports it.
