三个数组随机合并

三个数组随机合并；

            count_arr3:function(arr1,arr2,arr3){

                var arr = arr1.concat(arr2).concat(arr3);

                function shuffle(aArr){

                    var iLength = aArr.length,

                        i = iLength,

                        mTemp,

                        iRandom;

                    while(i--){

                        if(i !== (iRandom = Math.floor(Math.random() * iLength))){

                            mTemp = aArr[i];

                            aArr[i] = aArr[iRandom];

                            aArr[iRandom] = mTemp;

                        }

                    }

                    return aArr;

                }

                shuffle(arr)

                var sp_arr =[]

                $.each(arr,function(i,o){

                    sp_arr.push([o])

                })

                return sp_arr

            },

按时间排序三个数组

time_arr:function(arr1,arr2,arr3){

            var arr4 = arr1.concat(arr2).concat(arr3);

            var times =[];

            var arr = [];

            $.each(arr4,function(i,o){

                times.push(o.create_time)

            });

            times = times.sort(function(a,b){return b-a;})

            $.each(times,function(i,o){

                $.each(arr4,function(k,obj){

                    if(obj.create_time==o){

                        arr.push([obj])

                    }

                })

            });

            return arr;

        },
