jQuery cross domain AJAX request fails with XMLHttpRequest cannot load error

Question

I thought I was doing this right but I'm getting the following error in Chrome's JavaScript console:

XMLHttpRequest cannot load https://www.google.com/ig/calculator?hl=en&q=1USD=?JPY. 
Origin  is not allowed by Access-Control-Allow-Origin.

Any way I try and load the result through JQuery throws this error.

$.ajax({
    type: 'GET',
    url: 'https://www.google.com/ig/calculator?hl=en&q=1USD=?JPY',
    crossDomain: true
})
.fail(function() { alert('error'); })
.success(function(data) { alert(data); })
;
$.get('https://www.google.com/ig/calculator?hl=en&q=1USD=?JPY', function(data) {
    alert(data);
});
$("#test").load('https://www.google.com/ig/calculator?hl=en&q=1USD=?JPY', function(data) {
    alert(data);
});

Even specifying crossDomain to true the AJAX call still fails.

Any idea why or is there a better way to retrieve the results?

Thanks.

@Tom Why do you think Google allows it? Is it in some documentation somewhere? I'm looking at the HTTP response headers, and it looks pretty clear that Google does not allow it, because they don't send back an Access-Control-Allow-Origin response header, which is the mechanism by which Google allows cross-origin access to their pages. — apsillers

Your best bet is to create a REST/JSON service on your own web server that simply returns the remote results from Google's API.

That way any cross-domain problems are avoided and you have more control over future changes to the API (you can for example reformat the content to suit your own nefarious uses:)).

Yeah, the page is in ASP. Will have to try something there.
