Question

I’m guessing I will need to use javascript to do this, but I’m completely clueless. I’ve never used javascript before. Can someone give me a quick sample of how to change the visibility of a button based on a bool value in a JSP page?

Answer 1

If you are thinking about using it only once it’s easy to include JSP value in your JS code:

  <script type="text/javascript">
           var e = document.getElementById("foo");
            var myvar='<%=myScriptletVar %>'
            if (myvar)
                e.style.display = 'none'; 
    </script>
