I have a function foo which makes an Ajax request. How can I return the response from foo?

I tried to return the value from the success callback as well as assigning the response to a local variable inside the function and return that one, but none of those ways actually return the response.

function foo() {
    var result;

    $.ajax({
        url: '...',
        success: function(response) {
            result = response;
            // return response; // <- tried that one as well
        }
    });

    return result;
}

var result = foo(); // always ends up being `undefined`.

function foo() {

var result;

$.ajax({

url: '...',

success: function(response) {

result = response;

// return response; // <- tried that one as well

}

});

return result;

}

var result = foo(); // always ends up being `undefined`.
