js怎么写callback?

Question

function _parent(info){
        var a = info.x,b = info.y;
        var callMe = info.callMe;
        var sum = a+b;
        if(sum == 10){
            callMe;alert("!!!");
        }
    }
    window.onload = function(){
        _parent({
            x:5,
            y:5,
            callMe:function(){
                console.log("ture!@#");alert("success");
            }
        });
    }

为什么callMe没有执行啊...也没有alert("success").

Answer 1

callMe()加上括号表示方法调用。。。。
