JavaScript Location Object

The JavaScript Location object is a child object of the Window Object and is used to store information about the current URL of the Window object.

Loading a New URL into the Current Window

The location object contains a number of methods and properties that enable the JavaScript developer to manipluate the current URL of a window. A commom example is to progammatically change the current window URL. This can be done by assigning a new URL string to the href property of the Location option:

window.location.href="http://www.techotopia.com";

Reading the URL of the Current Window

It is also possible to read the URL of the current document. The simplest form of this is to access the href property of the Location object of the current window:

var currentURL=window.location.href;

It is also possible to access the various components that go to make up a complete URL. Suppose, for example, that the current URL is:

 http://www.techotopia.com:80/order.cgi?batch=1#intro
