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.

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";

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
