如何使用JavaScript OOP在附加的事件处理程序中引用此“真实”事件

使用局部变量“anyVariable”引用实例的最佳实践是什么

var myClass = (function () {
function myClass(gridId) {
    $(function () {
        // misc init code replaced here
        this.initKeyboard();
    });

}

myClass.prototype.initKeyboard = function () {
    var anyVariable = this; // keyword 'this' is clearly referring here to the instance
    $(document).keyup(function (e) {
        // I would like to refer here to the instance.
        // However it seems that the keyword 'this' refers here to the function (?)
        // Is is the best practice here to refer to the instance by using the local variable 'anyVariable'?
        anyVariable.myMember(...); //???
        }
    });
};

通常的变量名是

self

，

that

，或

\u this

（有关更多详细信息，请参见此），但这是在上下文更改时保持所需

this

值的常用方法。此外，您可以使用$.proxy
