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 |
