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

            

                

這是孫子元素，並祝福大家國慶快樂

js:

複製程式碼 程式碼如下:

 window.onload = function()
     {
         /*取得元素物件*/
         var father = document.getElementById('father');
         var son = document.getElementById('son');
         var grandson = document.getElementById('grandson');
         var data = document.getElementById('data');
         data.innerHTML = "

取得視窗大小(跟視窗大小有關)

";
         data.innerHTML = "document.body可見區域寬: " document.body.clientWidth "
";
         data.innerHTML = "document.body可見區域高: " document.body.clientHeight "
";
         data.innerHTML = "window.innerWidth可見區域寬: " window.innerWidth "
";
         data.innerHTML = "window.innerHeight可見區域高: " window.innerHeight "
";
         data.innerHTML = "document.documentElement可見區域寬: " document.documentElement.clientWidth "
";
         data.innerHTML = "document.documentElement可見區域高: " document.documentElement.clientHeight "
";
         data.innerHTML = "

取得元素自身大小(跟是否有捲軸無關)

";
         data.innerHTML = ".son自身寬度(offsetWidth屬性，包括左右邊框)：" son.offsetWidth "
";
         data.innerHTML = ".son自身高度(offsetHeight屬性，包括上下邊框)：" son.offsetHeight "
";
         data.innerHTML = ".son可視寬度(clientWidth屬性，不包括左右邊框)：" son.clientWidth "
";
         data.innerHTML = ".son可視高度(clientHeight屬性，不包括上下邊框)：" son.clientHeight "
";
         data.innerHTML = "

取得.grandson滾動大小和視覺大小

";
         data.innerHTML = ".grandson滾動寬度(scrollWidth屬性)：" grandson.scrollWidth "
";
         data.innerHTML = ".grandson滾動高度(scrollHeight屬性)：" grandson.scrollHeight "
";
         data.innerHTML = ".grandson可視寬度(clientWidth屬性，不包括垂直捲軸和border)：" grandson.clientWidth "
";
         data.innerHTML = ".grandson可視高度(clientHeight屬性，不包括水平捲軸和border)：" grandson.clientHeight "
";
         data.innerHTML = "

取得.grandson被捲去的大小(跟捲軸的位置有關)

";
         data.innerHTML = ".grandson被捲去的高(scrollTop屬性，垂直滾動條滑到最底端)：" grandson.scrollTop "
";
         data.innerHTML = ".grandson被捲去的左(scrollLeft屬性，水平滾動條滑到最右端)：" grandson.scrollLeft "
";
         data.innerHTML = "

取得瀏覽器視窗位置(跟視窗大小有關)

";
         /*
         *IE、Chrome、Safari、Opera 都提供了支援 window.screenLeft 和 *window.screenTop，但Firxfox不支援這兩個屬性；
         *Firxfox、Chrome、Safari、Opera 都提供了支援 window.screenX *和 window.screenY，但 IE 不支援這兩個屬性；
         */
         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 = "body網頁正文部分左(window.screenLeft(X))：" leftPos "
";
         data.innerHTML = "

取得螢幕解析度

";
         data.innerHTML = "螢幕解析度的高度(window.screen.height)：" window.screen.height "
";
         data.innerHTML = "螢幕解析度的寬(window.screen.width)：" window.screen.width "
";
         data.innerHTML = "

取得螢幕可用的高寬

";
         data.innerHTML = "螢幕解析度的高(window.screen.availHeight)：" window.screen.availHeight "
";
         data.innerHTML = "螢幕解析度的寬(window.screen.availWidth)：" window.screen.availWidth "
";
         data.innerHTML = "

取得.father的邊框大小

";
         data.innerHTML = ".father上邊框(clientTop)：" father.clientTop "
";
         data.innerHTML = ".father左邊框(clientLeft)：" father.clientLeft "
";
         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。
