逗号分割在阵列

Question

转换

["1","2","3,4","5","6","7,8,9"]到["1","2","3","4","5","6","7","8","9"]

的更好的想法每个条目我想要实现的是创造较少代码量，同时保持简单。

var arr=["1","2","3,4","5","6","7,8,9"]; 

var tmp=[]; 
for(var i=0,len=arr.length;i<len;i++){ 
    tmp=tmp.concat(arr[i].split(",")); 
}

我用简单的JS，但你可以使用任何类型的库，以减少代码。

Answer 1

使用加入和分割在一起。

arr.join(",").split(",");

Answer 2

你可以就地更换：（）

for(var i=arr.length-1; i>=0; i--) { 
    arr.splice.apply(arr,[i,1].concat(arr[i].split(","))); 
}
