How to change the value of a dropdown when user clicks on a radio button

Hi All,

I’m new to JavaScript.

Can Anyone give me a script to change the values of a drop-down when some other radio button is checked.

e.g. One Radio button is there. Default is male -> Drop down should not display any data
If we click on Female -In Age drop down it should disply a year 2000.

Thanks in advance.

Success!
