Javascript OOP - jQuery在ajax请求中调用"this"

Question

我想创建一个仍然保留对当前对象的访问权限的ajax请求.有谁知道这是否可能？

我想做的例子:

function mobile_as(as_object, inputID) {
    this.object = 'something';
    if (as_object) this.object = as_object;
    this.inputID = inputID;

    // Get results for later usage.
    this.get_results = function(value) {
            this.request = $.getJSON("URL", { as: this.object }, function (data) {
                // Scope of "this" is lost since this function is triggered later on.
                if (data['status'] == "OK") {
                    alert(this.inputID);
                }
            });
        }
    }
}

关闭救援:

function mobile_as(as_object, inputID) {
    var self = this; // <---------
    this.object = 'something';
    if (as_object) this.object = as_object;
    this.inputID = inputID;

    // Get results for later usage.
    this.get_results = function(value) {
            this.request = $.getJSON("URL", { as: this.object }, function (data) {
                // Scope of "this" is lost since this function is triggered later on.
                self.... //self is the old this
                if (data['status'] == "OK") {
                    alert(self.inputID);
                }
            });
        }
    }
}
