Can I use the jQuery $.ajax() method instead of the provided sample code? For some reason I am attempting this but it is not working:

$(function() {
    alert("Hi");
    $.ajax({
        url: "http://private-174c-themoviedb.apiary.io/3/search/movie?api_key=[pastedMyApiKeyHere]",
        contentType: "application/json",
        type: "GET",
        crossDomain: true,
        success: function(data) {
            alert("It worked");
        },
        error: function(err) {
            alert(JSON.stringify(err));
        }
    });
});

Any insight would be greatly appreciated. Thank you!
