Syntax
Tips and Notes
Note: This method changes the length of the array.
Tip: To remove and return the last element of an array, use the pop()
method.
Example
In this example we will create an array, and then remove the first element of
the array. Note that this will also change the length of the array:
<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.shift() + "<br />");
document.write(arr);
</script>
|
The output of the code above will be:
Jani,Hege,Stale
Jani
Hege,Stale
