I used this example.

Code:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<script language="javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.0/jquery.min.js" type="text/javascript"></script>

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>Test</title>

<script type="text/javascript"> 
 $(document).ready(function() {
     $('.hidable').hide();
           
                $('.link').each(function(){
                 
                 $(this).toggleClass("active").next();
                    $(this).click(function(){
                        var show=$(this).attr('rel');
                        $('.hidable').slideUp('slow');
                        $(show).slideDown('fast');
                    });

                });
            });

        </script> 
    </head> 
    <body> 
    
    <ul> 
     <li class='link' rel='#div1'><a href="#">1</a></li> 
     <li class='link' rel='#div2'><a href="#">2</a></li> 
     <li class='link' rel='#div3'><a href="#">3</a></li> 
     <li class='link' rel='#div4'><a href="#">4</a></li> 
     <li class='link' rel='#div5'><a href="#">5</a></li> 
  </ul> 
    
    <div id="boxes">       
     <div class='hidable' id='div1'><table><tr><td><img src="button.jpg"></td></tr></table></div>
     <div class='hidable' id='div2'>div 2</div>
     <div class='hidable' id='div3'>div 3</div> 
     <div class='hidable' id='div4'>div 4</div>
     <div class='hidable' id='div5'>div 5</div> 
 </div>
 
</body>
</html>
and I added button in div1 content. My problem is to link that button to another div in this html file. For example, when I click the button, it will open the div2 content. I've tried using <a href="#div2"><img src="button.jpg></a> but not working. How should I do this?
