Maybe it's because you set the type=submit in the form that contains the javascript.

You should set it to button or image or whatever if you don't want to be submitted if clicked cancel

example of javascript prompt:

function javascript_prompt(){
    var name = prompt("Tell me your name.", "");
    if (name != "" && name != null){
        document.form_name.new_name.value = name;
        document.form_name.submit();
    }else{
        return false;
    }
}
