Definition and Usage

The splice() method is used to remove and add new elements to an array.

Syntax

arrayObject.splice(index,howmany,element1,.....,elementX)

Parameter Description
index Required. Specify where to add/remove elements. Must be a number
howmany Required Specify how many elements should be removed. Must be a number, but can be "0"
element1 Optional. Specify a new element to add to the array
elementX Optional. Several elements can be added


Example

In this example we will create an array and add an element to it:

<script type="text/javascript">
var arr = new Array(5);
arr[0] = "Jani";
arr[1] = "Hege";
arr[2] = "Stale";
arr[3] = "Kai Jim";
arr[4] = "Borge";
document.write(arr + "<br />");
arr.splice(2,0,"Lene");
document.write(arr + "<br />");
</script>

The output of the code above will be:

Jani,Hege,Stale,Kai Jim,Borge
Jani,Hege,Lene,Stale,Kai Jim,Borge


Example

In this example we will remove the element at index 2 ("Stale"), and add a new element ("Tove") there instead:

<script type="text/javascript">
var arr = new Array(5);
arr[0] = "Jani";
arr[1] = "Hege";
arr[2] = "Stale";
arr[3] = "Kai Jim";
arr[4] = "Borge";
document.write(arr + "<br />");
arr.splice(2,1,"Tove");
document.write(arr);
</script>

The output of the code above will be:

Jani,Hege,Stale,Kai Jim,Borge
Jani,Hege,Tove,Kai Jim,Borge


Example

In this example we will remove three elements starting at index 2 ("Stale"), and add a new element ("Tove") there instead:

<script type="text/javascript">
var arr = new Array(5);
arr[0] = "Jani";
arr[1] = "Hege";
arr[2] = "Stale";
arr[3] = "Kai Jim";
arr[4] = "Borge";
document.write(arr + "<br />");
arr.splice(2,3,"Tove");
document.write(arr);
</script>

The output of the code above will be:

Jani,Hege,Stale,Kai Jim,Borge
Jani,Hege,Tove
