Array.removeAt(array, index);

Term

Definition

array

The array to remove the element from.

index

The index of the element to remove from the array.

Use the removeAt function to remove an item at a specific index from an array. The index value of items that are greater than index is decreased by one.

If index is a negative number, the removeAt function counts backward from the end of the array. Calling removeAt function with index greater than the length of the array has no effect.

The following example shows how to invoke the removeAt function to remove an item at a specified index from an array.

var a = ['a', 'b', 'c', 'd', 'e'];
Array.remove(a, 'c');
// View the results: "a,b,d,e"
alert(a);
Array.removeAt(a, 2);
 // View the results: "a,b,e"
alert(a);
