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(2,4) + "<br />");
document.write(arr);
</script>
|
The output of the code above will be:
Jani,Hege,Stale,Kai Jim,Borge,Tove
Stale,Kai Jim
Jani,Hege,Stale,Kai Jim,Borge,Tove
