Hi there asasass,
have you considered what happens for those visitors
who happen to have javascript disabled? 
This attachment has one button control for javascript
users and normal control for non-javascript users. 
It goes without saying, that the mark-up and the CSS
are very easy to maintain. 
Of course, I don’t expect you to use it though, but I am
posting it as it may be of mild interest to some members.
