这是我的编码。如果我单击并移动鼠标 onmousemove 事件应该发生。我怎样才能做到这一点。谁能帮帮我。

        <body>
        <img id="myImgId" alt="" src="Chrysanthemum.jpg" width="400" height="300" />

        <script type="text/javascript">
        <!--
        var myImg = document.getElementById("myImgId");
        myImg.onmousemove = GetCoordinates;
        //-->
        </script>


        <p>X:<span id="x"></span></p>
        <p>Y:<span id="y"></span></p>

您必须在点击事件中启用 onmouosemove 事件

</head>

    <body>
    <img id="myImgId" alt="" src="Chrysanthemum.jpg" width="400" height="300" onClick="doSomething(this)"/>

    <script type="text/javascript">

  function doSomething(obj)
  {
    obj.onMouseMove = function getCoordinates(){
          var x= screen.getX;
          var y = screen.getY;
          }
  }
   </script>


    <p>X:<span id="x"></span></p>
    <p>Y:<span id="y"></span></p>
