原谅伪代码,我的实际文件要大得多：/

我想从类中调用一个函数(带参数).但是,该函数应作为变量传递给类.

someObject = {
    itWorked:function(answer){
       alert(answer);
    },plugins:{
        somePlugin:function(){

            var callback;
            this.doSomething = doSomething;

            function setCallback(c){
                callback = c;
            }

            function doSomething(){
                 var answer = "hello";
                 [callback](answer); // how do I call this?
            }

        }
    },widgets:{
        something:function(){
            var doIt = new someObject();
            doIt.setCallback(someObject.itWorked()); // how do I send this?
            doIt.doSomething();
        }
    }
}

那么我如何将itWorked()传递给类？
我如何在类中调用itWorked(answer)函数以及将变量传递给if？
