JS控制的冒泡排序：

          

 <script type="text/javascript">

          var atter=[1,2,3,4,5,6,7,8,9];

         for(i=0;i<atter.length-1;i++)

   {

          for(j=0 ;j<atter.length-1-i;j++)

           {

                 if(atter[j]<atter[j+1])

                 {

                      var a = atter[j];

                      atter[j]=atter[j+1];

                      atter[j+1]=a;

                      }

                 }

                

         }

         alert(atter);

</script>
