請問如何在月曆控制項做計算
我在Dreamweaver設計了javascript calendar月曆控制項想在底下做2個欄位，讓使用者選了日期後
按下計算的按鈕，會顯示所選的日期會減15天和加15天
例如所選的是 2010/06/14，按下按鈕會顯示2010/05/30 和 2010/06/29
請問有什麼方法可以做 [list=1]
[*]先取得 calendar 元件被選取的日期
[*]轉成 timestamp
[*]加上 86400*1000*15 或減去 86400*1000*15
[*]再轉回日期
[/list]
例如當前時間 +15 天：
[code js]
var ts = new Date().getTime();
ts += 86400*1000*15;
alert(new Date(ts));
[/code] [b]回復 [url=http://jsgears.com/redirect.php?goto=findpost&pid=1430&ptid=502]2#[/url] [i]wmh[/i] [/b]
請問wmh大大
取得 calendar 元件被選取的日期的值是在哪段?
改過很多次都沒有顯示被選取的日期
不好意思 我是新手
月曆控制項是用 calender.mxp 擴充元件 這我也不清楚耶，我沒有在用 Dreamwaver :( 不一定要Dreamweavar
只想知道插入Java script之後
被選到日期的值是什麼[code]
