js怎么循环5个字符串比如:1,2,3,4,5
怎么循环出小面的格式:
1,2,3,4,5
2,3,4,5,1
3,4,5,1,2
4,5,1,2,3
5,1,2,3,4

Answer 1

a = [1,2,3,4,5];
for (var i = 0; i < 5; i++){
    console.log(a.slice(i).concat(a.slice(0,i)))
}

Answer 2

var zd = function(str,count,result){
    var arr = str.split(",");
    if(arr.length < count) return;
    result.push(arr.join(","));
    arr.push(arr.splice(0,1));
    count++;
    zd(arr.join(","),count,result);
};

var result = [];
var arr = zd("1,2,3,4,5",1,result);
console.log(result);
