如何存储一个小于前三个值的数组？

Question

I have this example:

var array=[0.1,2,3,4,6,7,8,9]

What I want is to store it in a variable only those values

var newArray=[3,4,6,7,8,9]

Of course, this must be dynamic ... regardless of the number of elements to store more than the first 3 items.

Answer 1

You need to use JavaScript's slice :

var array = [0.1,2,3,4,6,7,8,9];
var newArray = array.slice(2);
// [3, 4, 6, 7, 8, 9]

Usage : arr.slice([begin[, end]])

slice does not alter. It returns a shallow copy of elements from the original array. Elements of the original array are copied into the returned array.
