[英]How to split an specified number of elements from an array?
I have an array below: 我下面有一个数组:
var arr = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20];
and the length of the array is 20 and i am spliting it with 5 和数组的长度是20我将其拆分为5
When i specify 1, it should return [1,2,3,4,5] and if i specify 2, it should return [6,7,8,9,10] 当我指定1时,它应返回[1,2,3,4,5],如果我指定2,则应返回[6,7,8,9,10]
How can i get it through scripting? 如何通过脚本获取它?
Thanks for the help 谢谢您的帮助
You can use the .slice()
method to return a segment from an array. 您可以使用.slice()
方法从数组返回段。
For your case, you'd do something like this. 对于您的情况,您将执行以下操作。
arr.slice(5 * n, 5 * n + 5)
