  1.   

    同意，只要实现 body 的 onMouseMove 事件响应就可以了。再帖段代码供参考<html>
    <head>
    <title></title>
    <head>
    <script language="javascript">
    function testMouseMove(){
    x = window.event.x;
    y = window.event.y;

    output.innerText = "( x = " + x + ", y =" + y + " )"; 
    }
    </script>
    <body onMouseMove="testMouseMove()"> <table border="1">
    <tr>
    <td border="1"> 1 </td>
    <td border="1"> 2 </td>
    <td border="1"> 3 </td>
    <td border="1"> 4 </td>
    </tr>
    <tr>
    <td border="1"> 1 </td>
    <td border="1"> 2 </td>
    <td border="1"> 3 </td>
    <td border="1"> 4 </td>
    </tr>
    <tr>
    <td border="1"> 1 </td>
    <td border="1"> 2 </td>
    <td border="1"> 3 </td>
    <td border="1"> 4 </td>
    </tr>
    <tr>
    <td border="1"> 1 </td>
    <td border="1"> 2 </td>
    <td border="1"> 3 </td>
    <td border="1"> 4 </td>
    </tr>
    </table>
    <div id="output"></div>
    </body>
    </html>
      

  2.   

    var i=0;
    function MoveEvent()
    {
    document.getElementById("body1").onmousemove = function()
    {
    if(i==0)
    {
    i++;
    alert("xxx");
    }
    }
    }<BODY MS_POSITIONING="GridLayout" id="body1" onload="MoveEvent()">
      

  3.   

    <html> 
    <head> 
    <title> </title> 
    <head> 
    <script language="javascript"> 
    function testMouseMove(){ 
    alert(output)//不用任何声明 直接存在名为output的div对象？} 
    </script> 
    <body onMouseMove="testMouseMove()"> <table border="1"> 
    <tr> 
    <td border="1"> 1 </td> 
    <td border="1"> 2 </td> 
    <td border="1"> 3 </td> 
    <td border="1"> 4 </td> 
    </tr> 
    <tr> 
    <td border="1"> 1 </td> 
    <td border="1"> 2 </td> 
    <td border="1"> 3 </td> 
    <td border="1"> 4 </td> 
    </tr> 
    <tr> 
    <td border="1"> 1 </td> 
    <td border="1"> 2 </td> 
    <td border="1"> 3 </td> 
    <td border="1"> 4 </td> 
    </tr> 
    <tr> 
    <td border="1"> 1 </td>

    <td border="1"> 3 </td> 
    <td border="1"> 4 </td>

    <div id="output" style="background:red"> </div> </body>
