Syntax
Array.prototype.property
Array.prototype.method
The prototype property allows you to add new properties and methods to the Array object that can be used throughout your code.
The following example assigns a new method to the array object with the prototype property.
<html>
<script language="JavaScript">
<!--
function pop()
{
if(this.length != 0)
{
var lastElement = this[this.length-1];
this.length = this.length-1;
return(lastElement);
}
}
//Make the pop() function available to all Array objects
//This will override the pop() method provided by the Array object in Netscape
Array.prototype.pop = pop;
var flavorArray = new Array("A","B","C");
document.write(flavorArray.join(', '),"<br>");
var removedElement = flavorArray.pop();
document.write(removedElement," was removed from the flavor array.<br>");
document.write("new array: ");
document.write(flavorArray.join(', '),"<br>");
