JavaScript slice() Method


Array Object Reference JavaScript Array Object

Definition and Usage

The slice() method returns selected elements from an existing array.

Syntax

arrayObject.slice(start,end)

Parameter Description
start Required. Specify where to start the selection. Must be a number. Starts at 0
end Optional. Specify where to end the selection. Must be a number


Tips and Notes

Tip: You can use negative numbers to select from the end of the array.

Note: If end is not specified, slice() selects all elements from the specified start position and to the end of the array.


Example

Example

In this example we will create an array, and then display selected elements from it:

<script type="text/javascript">

var arr = new Array(6);
arr[0] = "Jani";
arr[1] = "Hege";
arr[2] = "Stale";
arr[3] = "Kai Jim";
arr[4] = "Borge";
arr[5] = "Tove";

document.write(arr + "<br />");
document.write(arr.slice(0,1) + "<br />");
document.write(arr.slice(2,4) + "<br />");
document.write(arr);

</script>

The output of the code above will be:

Jani,Hege,Stale,Kai Jim,Borge,Tove
Jani
Stale,Kai Jim
Jani,Hege,Stale,Kai Jim,Borge,Tove
