| 11.30.1.Array.splice() |
|
|
Syntax |
array.splice(start,delete,arg3,...,argN)
|
|
start -- The position in the array where the slice is to begin. |
delete -- The number of elements to be deleted from the array, beginning at the position specified by start. |
arg3,...,argN -- New array elements to be inserted into the array, starting at the position specified by start. |
Returns -- If any elements are deleted from the array, they are returned from the method as an array. |
The splice() method can either add elements to or delete elements from an array. |
When the delete parameter contains a number other than zero, the elements beginning at start and ending at index start+ending are deleted from the array. |
If delete is zero, no elements are deleted. |
All elements from start to the end of the array are deleted when delete is not specified. |
If arguments follow the delete parameter, they are added to the array as elements beginning at the position specified by start. |
Existing elements are shifted up to allow room for the new elements. |
