推荐答案

如果你可以使用jQuery，那么这个将有所帮助：

if you can use jQuery, then this will help:

<div id="divA" style="width:100px;height:100px;clear:both;"></div>
<span></span><span></span>
<script>
    $("#divA").mousemove(function(e){
      var pageCoords = "( " + e.pageX + ", " + e.pageY + " )";
      var clientCoords = "( " + e.clientX + ", " + e.clientY + " )";
      $("span:first").text("( e.pageX, e.pageY ) - " + pageCoords);
      $("span:last").text("( e.clientX, e.clientY ) - " + clientCoords);
    });

</script>

这里只是纯粹的javascript示例：

here is pure javascript only example:

var tempX = 0;
  var tempY = 0;

  function getMouseXY(e) {
    if (IE) { // grab the x-y pos.s if browser is IE
      tempX = event.clientX + document.body.scrollLeft;
      tempY = event.clientY + document.body.scrollTop;
    }
    else {  // grab the x-y pos.s if browser is NS
      tempX = e.pageX;
      tempY = e.pageY;
    }  

    if (tempX < 0){tempX = 0;}
    if (tempY < 0){tempY = 0;}  

    document.Show.MouseX.value = tempX;//MouseX is textbox
    document.Show.MouseY.value = tempY;//MouseY is textbox

    return true;
  }
