JS日期與時間選擇控制項升級版(自寫)_javascript技巧

鑑於網路上找到的幾個日期選擇程序有些問題，遂著手重寫一個程序，大部分還是藉鑑前人的代碼，添加了時間選擇功能，隱藏會遮擋控件的標籤select，object。
開始本想使用window.createPopup()來彈出日曆的選擇，這樣就可以跨越任何標籤。

不過做到中途發現用createPopup窗口實現理論上是行不通的：
一是因為不在窗體裡單擊任何地方都會關閉窗口，而當用下拉框選擇年份時，很有可能會點擊到窗體外的地方，當然這個可以自己寫select來避免，但是比較麻煩；
二是窗體的寬度和高度只能在彈出時設置，而顯然，在選擇不同年月時，控制高度是要改變的。

鑑於上述的原因，還是決定採用普通的處理方法。
 
Calendar.js:

複製程式碼 程式碼如下:

/**
*本日曆選擇控制由tiannet依據前人經驗完善而得。大部分程式碼來自meizz的日曆控制項。
*tiannet新增了時間選擇功能、select,object標籤隱藏功能，還有其它小功能。
*使用方法：
* (1)只選擇日期
* (2) 選擇日期和小時
* (3)選擇日期和小時及分鐘
*設定參數的方法
* (1)設定日期分隔符號setDateSplit(strSplit);預設為"-"
* (2)設定日期與時間之間的分隔符號setDateTimeSplit(strSplit);預設為" "
* (3)設定時間分隔符號setTimeSplit(strSplit);預設為":"
* (4)設定(1),(2) ,(3)中的分隔符號setSplit(strDateSplit,strDateTimeSplit,strTimeSplit);
* (5)設定開始與結束年份setYearPeriod(intDateBeg,intDateEnd)
*說明：
* 預設回傳的日期時間格式如同：2005-02-02 08:08
