jQuery.get XML文件从URL

So i have a simple task, get an xml feed from a server that is not ours. easy enough, however im running into allow origin control issues and the &callback= tag isnt solving the issue.

$.get("http://www.buytopia.ca/feed",data,jloop(),"xml");

function jloop(){
        var count=0;
        //dummy code
        document.write("please work");
        do{
            document.write(count);
            count++;
        }
        while (count<10);

    };

so when i run this, the get call is pending, not retieving. ive tried different feeds, like NASA but adding the &callback= doesnt remove access origin problems. All i need is a working chunk of code to get the feed, preferably to that buytopia.ca feed because we have access to it and know its permission info. Then i can begin to parse it. Any help would be great! thanks!

Is buytopia your domain. You cant make ajax calls accross domains. Its called cross site scripting.

https://en.wikipedia.org/wiki/Cross-site_scripting

You can do an ajax call to a local php file (let's say you call it currency.php), and get it through php as in, for example (the php is from ECB's web site, for developers - the ajax is mine)

  $XML=simplexml_load_file("http://www.ecb.europa.eu/stats/eurofxref/eurofxref-daily.xml");

  //the file is updated daily between 2.15 p.m. and 3.00 p.m. CET 

    foreach($XML->Cube->Cube->Cube as $rate){
        //Output the value of 1EUR for a currency code
        echo '1&euro;='.$rate["rate"].' '.$rate["currency"].'<br/>';

        if ($rate["currency"]=='USD') {
            echo 'EUR-> USD RATE: '.$rate["rate"], '<br/>';
        }
        //--------------------------------------------------
        //Here you can add your code for inserting
        //$rate["rate"] and $rate["currency"] into your database
        //--------------------------------------------------
    }

Then the ajax call would be something like:

<script>
 $.ajax({
        url: 'currency.php',
        type: 'POST',
        data: {myCurrency: curr,
               myPriceAmt: amount },  
        success: function(data){
            // do any manipulations here

        }
 });
 </script> 

Good luck!
