基于javascript实现九九乘法表

<script type="text/javascript">    var sum=0;    var wite;    for (var i = 1; i < 10; i++){      var div=$('<div class="class'+i+'"></div>');      $("body").append(div);      for(var j = i; j > 0; j--){        sum = j * i;        wite = (j+"X"+i+"="+sum);        div.prepend($('<span style="padding-right:10px">'+wite+'</span>'));      }          }   </script>
