------解决方案-------------------- <script>    
 // Here are the initial values for our animation   
 var x = 0, y = 0, w=200, h=200;  // Window position and size   
 var dx = 5, dy = 5;              // Window velocity   
 var interval = 100;              // Milliseconds between updates     
 // Create the window that we 're going to move around   
 // The javascript: URL is simply a way to display a short document   
 // The final argument specifies the window size   
 var win = window.open( 'javascript: " <h1> BOUNCE! </h1>  " ',  " ",    
                        "width= " + w +  ",height= " + h);     
 // Set the initial position of the window   
 win.moveTo(x,y);     
 // Use setInterval(  ) to call the bounce(  ) method every interval    
 // milliseconds. Store the return value so that we can stop the   
 // animation by passing it to clearInterval(  ).   
 var intervalID  = window.setInterval( "bounce(  ) ", interval);     
 // This function moves the window by (dx, dy) every interval ms   
 // It bounces whenever the window reaches the edge of the screen   
 function bounce(  ) {   
     // If the user closed the window, stop the animation   
     if (win.closed) {   
         clearInterval(intervalID);   
         return;   
     }     
     // Bounce if we have reached the right or left edge   
     if ((x+dx >  (screen.availWidth - w)) || (x+dx  < 0)) dx = -dx;     
     // Bounce if we have reached the bottom or top edge   
     if ((y+dy >  (screen.availHeight - h)) || (y+dy  < 0)) dy = -dy;     
     // Update the current position of the window   
     x += dx;   
     y += dy;     
     // Finally, move the window to the new position   
     win.moveTo(x,y);   
 }   
  </script>      
  <!-- Clicking this button stops the animation! -->    
  <form>    
  <input type= "button " value= "Stop "    
        onclick= "clearInterval(intervalID); win.close(  ); ">    
  </form>      
 这个是移动窗口的例子
