Clear all data and turn back to default settings

Clear all data and turn back to default settings

Goal:
When I click on the clear all button and the data inside of the input box should be empthy and the dropdownlist should go back to default settings that is year 2009.

Problem:
I don't know how to do in order to make the dropdownlist to go back to default when you have pressed the button?

Info:
Please remember that I do not want to make any big changes in the current javascript/jquery source code because it is used in production phase. I would like to make a complementary or add ing new code to the current source code.

I tried using <input type="reset" value="Clear alll" name="clear_all"> but it doesn't work in long term with the current source code.


Thanks!
