How to activate a button when Facebook "like" button has been clicked?

[Extra Domus]

Hey there, I have a blog where I put my music on and I am seeking a way to make people click "like" on my facebook page to unlock the download button. So far I got my "like" button, my D/L button (which is just linked to filefactory since I don't own the domain on blogspot). I disabled the D/L button but I need it to reactivate once the person likes my page.

How do I proceed?

Set the disabled property of the button to false onclick:

btn.disabled=false

where btn is a reference to the button object.
