默認(rèn)情況下 jscalendar -1.0包中所附的中文語言文件（calendar-cn_utf8.js）不支持中文是由于沒有設(shè)置每周的開始日期
修改方法是在語言文件calendar-cn_utf8.js 開始部分加上

      Calendar._FD = 0;
    

修改后的文件如下：

      Calendar._FD = 0;
// full day names exp:星期日
Calendar._DN = new Array

同時在用到該控件的頁面必須加上

      <link href="css文件" type="text/css" rel="stylesheet" />

    

附：今天在另外一個JSP頁面用到的時候，出現(xiàn)了彈出的面板不顯示任何日期的情況，檢查了N遍，發(fā)現(xiàn)與好用的頁面代碼相同，但是嘗試了多種方法后問題依然存在。
最后將日期js文件在頁面調(diào)用的路徑更改了一下，這樣當(dāng)然找不到了，報(bào)錯；然后再改回來，這下竟然好用了。
具體什么原因我也不知道。經(jīng)常變動JSP頁面內(nèi)容的時候有時我們會發(fā)現(xiàn)，其實(shí)頁面的語句是正確的，但是在Ecpipse中仍然顯示有問題，沒有辦法你必須將這個語句改錯誤，然后保存，之后再改回來，再保存，語句沒有問題多數(shù)情況問題會解決。
好多人都遇見過這樣的問題，為甚么這么解決它們也不知道具體原因，大概JSP頁面被編譯后駐留在內(nèi)存中，和這個有關(guān)吧。
