javascript - Ajax 请求。哪个回调先执行完成或成功？

Question

我可以点击它来找出答案，但我将使用 SO。在我的单元测试 (qunit) 中，我使用 asynchShould(asynchTest 的别名)测试。断言的一部分是等待请求的完成/成功。像这样:

asyncShould('talk to customer list server', 1, function() {
    stop(2000);
    var forCustomerList = newCustomerListRequest();

    forCustomerList.page = 'helpers/helper.php';
    forCustomerList.data += '&action=customerListServer&DB=11001';
    var originalSuccess = forCustomerList.success;

    forCustomerList.success = function(msg) {
        if (msg.flash !== undefined && msg.data !== undefined && msg.status !== undefined) {
            ok(true, 'json structure correct')
        }
        else {
            ok(false, 'json structure not correct');
        }
        originalSuccess(msg);
        start();
    };

    testController.getServerData(forCustomerList);
})

成功

来自 jQuery 站点 http://api.jquery.com/jQuery.ajax/

complete(XMLHttpRequest, textStatus)Function

A function to be called when the request finishes (after success and error callbacks are executed)...
