看完《javascript语言精粹》中的array.sort(comparefn)一节（Page81），很有启发性，于是自己试着实现这样一个通用函数by：无论数组对象为何种类型，调用此函数就能实现人们一般认知意义上的排序。

函数写完，发现没有起作用，debug了好久，最后还是决定求助了！（http://sfau.lt/bNWpU）很快得到了的解答，感谢他的帮助！

附上函数代码：

var by = function (name,minor){        return function (a,b){            var objBy =  function (a,b){                var aValue,bValue;                            aValue = a[name];                bValue = b[name];                if (aValue === bValue){                    return typeof minor === 'function' ? minor(a,b) : 0;                }                if (typeof aValue === typeof bValue){                    return aValue < bValue ? -1 : 1;                }                    return typeof aValue < typeof bValue ? -1 : 1;                    }            var generalBy  = function (a,b){                if (a === b){                    return 0;                }                if (typeof a === 'string' && typeof b === 'string'){                    return a.localeCompare(b);                }                if (typeof a === typeof b){                    return a < b ? -1 : 1;                }                    return typeof a < typeof b ? -1 : 1;                }                        if (a && b && typeof a ==='object' && typeof b === 'object'){                            return objBy(a,b);                        }            return generalBy(a,b);                                    }                }                        var arry1 = [8,90,10,2,100,34,35,12];    var arry2 = [4,20,10,34,"hello word","杀星","my god","哈哈哈","高级编程","爱情","四货","一个人" ,"大人"];    var arry3 = [{name:"maggie",sex:"famale",age:43},{name:"gino",sex:"male",age:28},{name:"laura",sex:"famale",age:20},{name:"tino",sex:"male",age:25},{name:"amy",sex:"famale",age:27}];        console.log(arry1.sort(by()));    console.log(arry2.sort(by()));    console.log(arry3.sort(by('sex',by('age'))));
