Redirection with JavaScript OR jQuery.

For redirect a page to another page in client side you can use window.location. For this you need not to include the jQuery file.

Question: What is window.location?
The window.location is a object which have all the values like host, href, port and username etc of current location. It is used to get the current page address (URL) and to redirect to a new page.

When I do console.log(JSON.stringify(window.location)), It print following data.

 
{"href":"http://www.web-technology-experts-notes.in/2014/10/jquery-technology.html","origin":"http://www.web-technology-experts-notes.in","protocol":"http:","username":"","password":"","host":"www.web-technology-experts-notes.in","hostname":"www.web-technology-experts-notes.in","port":"","pathname":"/2014/10/jquery-technology.html","search":"","hash":""}

To use the window.location, Its not necessary to include the jQuery.
