There is no such thing as "Java script". Java is not a scripting language. ;-)
Yes, you mentioned JavaScript, but did you know that there is also a programming language called "Java", which has nothing to do with JavaScript?

Post your code, but I suspect the issue is that you're not cancelling the click event of the button so after showing your alert it is maybe then submitting the form. Something like that, without seeing the code it's impossible to say. Your button event should be something like onclick="showAlert(); return false;"
