转贴:用文章供稿RSS时间设定做成的日历模组(Feed Calendar)

感谢作者Abin给大家带来的日历模组 (Feed Calendar)。因为我个人不用这个hack,所以懒得测试了……全文转载……大家有问题问作者哈。
另外作者博客被封,可能要用代理才能查看原文和询问作者。

似乎比较近似我以前发的一个HACKblogger:把博客归档变成日历的又一方法(再修正),相对简单的还有利用light box和30box制作出日历的方法,点击这里查看

作者原文的HACK增加方法:
第一個步骤,先塞入這個日曆外觀顏色的 CSS 樣式定義。如果你用過之前日曆,那就不用改啦,因為我用了一樣的定義,打開版面配置、修改樣板原始碼的 HTML,放在 <head> 標籤內、定義 CSS 樣版的區段裡:


/* Feed Calendar Styles */

#Calendar {

  margin: 0px;

}

#Calendar .act {


  color: #fff;

  padding: 4px;

}

#CalendarTable table {

  border-collapse: collapse;

  padding: 0px;

  border: 0px;


}

#CalendarTable table th {

  padding: 1px;

  color: #777;

  margin: 0;

}

#CalendarTable table td {


  height: 25px;

  color: #999;

  text-align: center;

  padding: 1px;

  margin: 0;

}


#CalendarTable table td a {

  display: block;

}

#CalendarTable .Today {

  color: #fff;

  background: #777;

}


#CalendarTable .Today a {

  color: #fff;

}

#CalendarTable .Weekend {

  color: #997777;

}

如果對顏色、字型大小、靠左靠右有特別需求的,請自行改上面的樣式。第二個步驟是重點,就是抓 Feed、產生日曆主要的 Javascript 程式碼,一樣是貼在 <head> 標籤後面,如果你之前也有 Hack 放過 Javascript,放在一起就好:


<script type='text/javascript'>

好啦!樣板原始碼的修改到此搞定存檔,接下來安排這個新日曆模組的位置。換到「網頁元素」的設定,在你想塞入日曆的地方新增一個網頁元素、選擇 HTML/JavaScript 類型。接下來給個標題,然後貼入以下的 HTML 程式:

<center>

  <table border="0" id="Calendar" cellpadding="0" cellspacing="0">


    <caption>

      <a href="javascript:;" onclick="BrowsePrev();" title="Previous Month">&lt;&lt;</a>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

      <a href="javascript:;" onclick="BackToday();" title="Back to Today"> <span id="CalendarCaption"> </span></a>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;


      <a href="javascript:;" onclick="BrowseNext();" title="Next Month">&gt;&gt;</a>

    </caption>

    <tr>

      <td id="CalendarTable" class="act"> </td>


    </tr>

  </table>

  <script type="text/javascript">

    generateCalendar();

  </script>

</center>


儲存搞定!接下來就可以檢查新的日曆模組能不能動囉~當然,根據以上的原理來說,這個新的日曆模組應該沒啥問題(我自己所有的 Blog 也都裝來用啦),不過如同大部份透過 Feed 抓文章的 Hack 一樣,由於要仰賴 Feed 即時連線抓取資料來源,這點會受到網路影響,所以快速猛點連結時切換的反應會比較慢(這是 Feed 的原罪,沒辦法),所以如果日曆有出現、但該日期沒有文章連結,請先檢查 Feed 的內容是不是正常,如果貼完程式發現怎麼只有兩個箭頭,那就是程式貼錯地方或貼漏了,請自己再仔細檢查一下。
