How to automatically change the page contents with change in drop down list option selection

[MaheshS Kumbhar]

I have one jsp page with drop down list with options.
For different options in drop down list, I want to display different page content, either on the same jsp page containing the drop down list or possibly on some other page.
There is no submit button to submit the user selected value from drop down list. The page contents should automatically change or redirect to another page as soon as user makes a change in drop down list.

I want to know how to do this.

Can anyone please guide me on how to do this.
