Blogger相关文章模块

感谢GG（没找到你的地址）提醒：只要“：”这个符号是英文标点":"，就能查询这个英文冒号前的中文，从而搜索相关文章。

这段JS是根据文章标题来过滤相关文章的，所以对中文支持不怎么样，效果见这篇文章。

这个模块可以在侧边栏上显示出与当前正查看的文章相关的文章。只在某一项目页起作用。不太完美的地方就是要等一段时间才会把相关文章“过滤”出来。添加也非常简单，无须展开代码，找到侧边栏的任意两个b:widget之间，把下面的代码加上就行。

<b:widget id='BlogArchive2' locked='false' title='相关文章' type='BlogArchive'>
<b:includable id='main'>
<b:if cond='data:blog.pageType == "item"'>
<b:if cond='data:title'>
<h2 id='relatedTitle'><data:title/></h2>
</b:if>
<div class='widget-content'>
<div id='RelatedPosts'>
<div expr:id='data:widget.instanceId + "_ArchiveList2"'>
<b:if cond='data:style == "HIERARCHY"'>
<ul id='relatedArticles'><b:include data='data' name='interval'/></ul>
</b:if>
</div>
</div>
<b:include name='quickedit'/>
</div>
