    objects mistake

    Hello,
    when I was trying with a new source code I have the problem with my
    for-loop.
    So I use 'f.elements' but it is to object to this line:
    (var i=0;i<f.element s.length;i++).
    I want to count all elements(checkb oxes).
    Maybe somebody has another source code?

      It's impossible to guess what you've done wrong from that
      single line of code.

      <html>
      <body>
      <script type="text/javascript">
      function countCheckboxes (f){
      var count=0;
      for(var i=0;i<f.element s.length;i++){
      if(f.elements[i].type=="checkbo x"){
      count++;
      }
      }
      alert("There are "+count+" checkboxes in this form.");
      }
      </script>
      <form>
      <input type="checkbox" >
      <input type="checkbox" >
      <input type="checkbox" >
      <input type="checkbox" >
      <input type="button" value="count" onclick="countC heckboxes(this. form)">
      </form>
      </body>
      </html>
