jQuery ajax调用（2）

Can anyone tell me what is wrong with this ?

<!DOCTYPE html>
<html>
<head>
<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
<script>
$(document).ready(function() {
    var url = 'http://www.google.com/ig/calculator?hl=en&q=100INR=?USD';
    var title = "jQuery";

    $.getJSON("http://www.google.com/ig/calculator?hl=en&q=100INR=?USD" + "&format=json&callback=?", function(data) {
        alert(data);
    });
});


<div id="div1">Test Page</div>

I am making the call and I am getting an error. You know why ? How do I make ajav calls to the url http://www.google.com/ig/calculator?hl=en&q=100INR=?USD

You can't make AJAX calls cross-domain. You will need to use something like JSONP to make it work cross-domain.

jQuery's $.ajax method supports JSONP requests. If the Google API doesn't support JSONP style responses, you are out of luck. Using a proxy, as suggest by @FelixKling, is the other option.
