- js 和 jquery 擷取頁面和捲軸的高度
-

- jquery
-
- 擷取瀏覽器顯示地區的高度 ：
- $(window).height();
- 擷取瀏覽器顯示地區的寬度 ：$(window).width();
- 擷取頁面的文檔高度
- ：$(document).height();
- 擷取頁面的文檔寬度 ：$(document).width();
-
- 擷取捲軸到頂部的垂直高度
- ：$(document).scrollTop();
- 擷取捲軸到左邊的垂直寬度 ：$(document).scrollLeft();
-
-
- 計算元素位置和位移量
-
- offset方法是一個很有用的方法，它返回封裝集中第一個元素的位移資訊。預設情況下是相對body的位移資訊。結果包含 top和left兩個屬性。
-
- offset(options, results)
- options.relativeTo 指定相對計
- 算位移位置的祖先元素。這個元素應該是relative或absolute定位。省略則相對body。
- options.scroll 是否把
- 捲軸計算在內，預設TRUE
- options.padding 是否把padding計算在內，預設false
- options.margin
- 是否把margin計算在內，預設true
- options.border 是否把邊框計算在內，預設true
