JavaScript push() Method


Array Object Reference Complete Array Object Reference

Definition and Usage

The push() method adds one or more elements to the end of an array and returns the new length.

Syntax

arrayObject.push(newelement1,newelement2,....,newelementX)

Parameter Description
newelement1 Required. The first element to add to the array
newelement2 Optional. The second element to add to the array
newelementX Optional. Several elements may be added


Tips and Notes

Note: This method changes the length of the array.

Tip: To add one or more elements to the beginning of an array, use the unshift() method.


Example

In this example we will create an array, and then change the length of it by adding a element:

<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.push("Kai Jim") + "<br />");
document.write(arr);
</script>

The output of the code above will be:

Jani,Hege,Stale
4
Jani,Hege,Stale,Kai Jim
