Syntax error on if-else Javascript statement

Question

I'm fairly new to JavaScript so I don't quite understand why I am getting a syntax error on 'else'. Any advise?

<script language="javascript">
 $(document).ready(function() {
      $('#toggleButton').click(function() {
           if ($('#toggleSection').css("opacity") == 0); {  
                $('#toggleSection').fadeIn("slow");
           } 
           else {
                $('#toggleSection').fadeOut("slow");
           }
           return false;
      });
 });
 </script>

For basic syntax errors, just run your code through jslint.com. — Matt Ball

if ($('#toggleSection').css("opacity") == 0);

Remove that semicolon on the end..

if ($('#toggleSection').css("opacity") == 0); {

Hi, I think your ; is wrong here. Good luck!

You have an extra ; after the if

This is parsed as an if around an empty statement (which is useless), followed by an ordinary { ... } block, followed by a dangling else.
