javascript - JQuery:在回调中引用外部范围

Question

我对 OO Javascript 和 jQuery 回调有疑问。如果您查看下面的示例，它应该可以解释一切。

我如何在此函数感知中调用 functionToCall() 的深处。

function outerClass() {
    this.functionToCall = function() {
        //do something
    }

    this.someOtherFunction = function() {

    this.aCoupleOfVariables1 = 2;
    this.aCoupleOfVariables2 = "stuff";

    $.ajax({
        success: function() {
        //How do I call functionToCall() right here
        //TRIED:
            functionToCall();
            this.functionToCall();
            that.functionToCall();
        }
    }); 
    }
}

您可以将 this 作为 context 选项传递给 $.ajax() :

$.ajax({
    context: this,
    success: function() {
        // Here, 'this' refers to the same object as in the caller.
        this.functionToCall();  
    }
});
