问您好，最近在学习这个项目相关，请问是否能提供完整代码呢？

var myObj = {

    1: ['c', 'd'],

    2: ['a', 'b']

  },

  myArr;

myObj.length = 3; //max index + 1

myArr = Array.prototype.slice.apply(myObj);

console.log(myArr); //[undefined, ['c', 'd'], ['a', 'b']]

var myObj = {

    1: [1, 2, 3],

    2: [4, 5, 6]

};

var array = $.map(myObj, function(value, index) {

    return [value];

});

console.log(array);

[[1, 2, 3], [4, 5, 6]]
