在 Blogger 中插入月曆

為了在 blogger 中插入月曆，真是費了一番工夫。總共參考了好幾篇文章：

1. 笨蛋壩子的隨筆 -- 在Blogger上安插月曆( Calendar) - IE 修正版
2. Kevin的私人書房 -- 實作Blogger月曆( Calendar)
3. Abin's Tech Note -- 為 Blogger 加入整合日曆 Archive Calendar

當然，純粹需要月曆的功能，像 google calendar 之類的外掛就可以用了，不過樣式不好看，而且就只是單純月曆的功能。而現在的這個方法，則是把月曆與 blog 存檔整合，點擊月曆上的日期就可以看到當天所發表的文章。一開始，照著笨蛋壩子的方法做，在最後一個步驟會卡住。接著換到 Kevin 的方法，顯示卻有問題，後來換到 Abin 的方法，月曆終於可以顯現出來，不過顏色不太合，因此我是用一部份笨蛋壩子的程式碼，再加上一部份 Abin 的程式碼。好吧，其實是我比較懶，懶得去學怎麼改顏色等等的方法，只會貼來貼去的。我的方法如下：

首先，在 /* Footer 之前插入以下程式碼

/* Calendar v0.3
----------------------------------------------- */
#Calendar {
border:1px solid #222;
margin:0px;
}
#Calendar caption {
color:#fff
}
#Calendar caption a:link, #Calendar caption a:visited, #Calendar caption a:hover, #Calendar caption a:active {
color:#777;
text-decoration:none;
}
#Calendar caption today{
font-weight:light;
font-size:smaller;
}
#CalendarTable a:link, #Calendar a:visited, #Calendar a:active{
text-decoration:none;
font-weight:bold;
Text-decoration:underline;
color: #fff;
}
#CalendarTable a:hover {
text-decoration:none;
}
#CalendarTable table {
border-collapse:collapse;
padding:0px;
border: 0px;
}
#CalendarTable table th {
font-family:Arial;
font-size:12px;
padding: 1px;
color:#777;
margin: 0;
}
#CalendarTable table td {
font-family:Arial;
font-size:12px;
height:25px;
border: 1px solid #444;
color:#777;
text-align:center;
padding: 1px;
margin: 0;
}
#CalendarTable table td a {
display: block;
}
#CalendarTable .Today {
color: #fff;
background: #444;
}
#CalendarTable .Today a {
}
#CalendarTable .Lastday {
}
#Calendar .act {
color:#000;
padding:4px;
}


接下來，在 /head 之前插入

<script type='text/javascript'>

最後，找到以下的程式碼 (這部份需要先啟用 blog 存檔)

<b:includable id='flat' var='data'>
<ul>
<b:loop values='data:data' var='i'>
<li class='archivedate'>
<a expr:href='data:i.url'><data:i.name/></a> (<data:i.post-count/>)
</li>
</b:loop>
</ul>
</b:includable>


置換成以下：

<b:includable id='flat' var='data'>
<!-- Generate Archive Calendar -->
<center>
<table border='0' cellpadding='0' cellspacing='0' id='Calendar'>
<caption>
<a href='javascript:;' onclick='Calendar.PrevMonth();' title='Previous Month'><< </a>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
<a href='javascript:;' onclick='Calendar.GoToday();' title='Back to Today'> <span id='CalendarMonth'/> </a>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
<a href='javascript:;' onclick='Calendar.NextMonth();' title='Next Month'> >></a>
</caption>
<tr>
<td class='act' id='CalendarTable'> </td>
</tr>
</table>
<script type='text/javascript'>
Calendar = new ArchiveCalendar();
Calendar.base = 'http://abintech.azhai.org/';
var offset = Calendar.base.length;
<b:loop values='data:data' var='i'>
archUrl = '<data:i.url/>'.slice(offset);
Calendar.blogarchivename.push(archUrl.slice(0,4) + archUrl.slice(5,7) + archUrl.slice(8,10));
</b:loop>
Calendar.refreshTable();
</script>
</center>
</b:includable>
