constrain number of clicks

@mduranMay 18.2005

Hi,

I am building a page for listening tests. I would like to give the test subjects the possibility to listen to every wav file a limited number of times (say 3). Then I would like to hide the link to the wav file.

How can I do this ?

Much appreciated.

@mduranauthorMay 18.2005 — #Yeah I know. What I want is to hide the link to the wav after x number of times, which will make their life a bit more difficult if they want to listen again.

[CODE]<script>
 var clicks1 = 0; 
 var clicks2 = 0; 
 var clicks3 = 0; 
 
  function countClicks(number) {
   //Open link to Wav sound using window.open here
   // if number = 1 then open link 1 etc.
 
   eval("clicks" + number + " = clicks" + number + " + 1;");
   if (eval("clicks" + number + ";") > 2  ) 
   {
   eval("link"+ number + ".style.display = 'none';");
   }
  }
 
 </script>
 
 <a id=link1 href="javascript:void(0)" onclick="countClicks(1);">Link 1</a>
 <br>
 <a id=link2 href="javascript:void(0)" onclick="countClicks(2);">Link 2</a>
 <br>
 <a id=link3 href="javascript:void(0)" onclick="countClicks(3);">Link 3</a>[/CODE]
