DIV CSS 佈局教程網

鑒於網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，大部分還是借鑒前人的代碼，添加了時間選擇功能，隱藏會遮擋控件的標簽select，object。
開始本想使用window.createPopup()來彈出日歷的選擇，這樣就可以跨過任何標簽。

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，很有可能會單擊到窗體外的地方，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，控件高度是要發生改變的。

鑒於上面的原因，還是決定采用普通的處理方法。
 
Calendar.js:
復制代碼 代碼如下:
/**
*本日歷選擇控件由tiannet根據前人經驗完善而得。大部分代碼來自meizz的日歷控件。
*tiannet添加了時間選擇功能、select,object標簽隱藏功能，還有其它小功能。
*使用方法：
* (1)只選擇日期 <input type="text" name="date" readOnly onClick="setDay(this);">
* (2)選擇日期和小時 <input type="text" name="dateh" readOnly onClick="setDayH(this);">
* (3)選擇日期和小時及分鐘 <input type="text" name="datehm" readOnly onClick="setDayHM(this);">
*設置參數的方法
* (1)設置日期分隔符 setDateSplit(strSplit);默認為"-"
* (2)設置日期與時間之間的分隔符 setDateTimeSplit(strSplit);默認為" "
* (3)設置時間分隔符 setTimeSplit(strSplit);默認為":"
* (4)設置(1),(2),(3)中的分隔符 setSplit(strDateSplit,strDateTimeSplit,strTimeSplit);
* (5)設置開始和結束年份 setYearPeriod(intDateBeg,intDateEnd)
*說明：
* 默認返回的日期時間格式如同：2005-02-02 08:08
