JavaScript slice() Method

Complete Array Object Reference

Definition and Usage

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

Syntax

arrayObject.slice(start,end)

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 1

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

<script type="text/javascript">

var arr = new Array(3);
arr[0] = "Jani";
arr[1] = "Hege";
arr[2] = "Stale";

document.write(arr + "<br />");
document.write(arr.slice(1) + "<br />");
document.write(arr);

</script>

The output of the code above will be:

Jani,Hege,Stale
Hege,Stale
Jani,Hege,Stale

Example 2

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
