html代碼：

這是父元素，而螢幕解析度是1366*768

這是子元素，並祝福大家國慶快樂

     }

     .father

     {

         width: 500px;

         height: 750px;

         border: 5px solid red;

         float: left;

         var leftPos = (typeof window.screenLeft == 'number')?window.screenLeft:window.screenX;

         var topPos = (typeof window.screenTop == 'number')?window.screenTop:window.screenY;
         data.innerHTML = "body網頁正文部分(window.screenTop(Y))：" topPos "

         data.innerHTML = "取得.son到父元素邊界的距離(即對應margin 父元素對應的border)";

         data.innerHTML = ".son到父元素上邊界(offsetTop)：" son.offsetTop "
";

         data.innerHTML = ".son到父元素左邊界(offsetLeft)：" son.offsetLeft "

     }

ps：瀏覽器對盒子的解析有差異，所以以上所得的資料也會有小小差異。附圖一張。
