如何为Blogger添加相关文章

从blogger后台进入"布局-修改HTML"。注意先check"扩展窗口小部件模板"，这样会显示完整的模板文件。
在</head>前加入下面代码，其中加粗内容控制数量。
<script type='text/javascript'>
//<![CDATA[

var relatedPostsNum = 0;
var relatedTitles = new Array();
var relatedUrls = new Array();
var relatedDates = new Array();

function RelatedLabels(json) {
  var regex1=/</g, regex2=/>/g;
  for (var i = 0; i < json.feed.entry.length; i++) {
    var entry = json.feed.entry[i];
    relatedTitles[relatedPostsNum] = (entry.title.$t.replace(regex1, '<')).replace(regex2, '>');
    relatedDates[relatedPostsNum] = entry.published.$t.substr(0,10);
    for (var j = 0; j < entry.link.length; j++) {
      if (entry.link[j].rel == 'alternate') {
        relatedUrls[relatedPostsNum] = entry.link[j].href;
        relatedPostsNum++;
        break;
      }
    }
  }
}

function RemoveDuplicatedPosts(PostUrl) {
  var tmpUrls = new Array(0);
  var tmpTitles = new Array(0);
  var tmpDates = new Array(0);
  function contains(a, e) {
    for(var j = 0; j < a.length; j++)
      if (a[j]==e)
        return true;
    return false;
  }
  for(var i = 0; i < relatedUrls.length; i++) {
    if(!contains(tmpUrls, relatedUrls[i]) && PostUrl != relatedUrls[i]) {
      tmpUrls.length += 1;
      tmpUrls[tmpUrls.length - 1] = relatedUrls[i];
      tmpTitles.length += 1;
      tmpTitles[tmpTitles.length - 1] = relatedTitles[i];
      tmpDates.length += 1;
      tmpDates[tmpDates.length - 1] = relatedDates[i];
    }
  }
  relatedTitles = tmpTitles;
  relatedUrls = tmpUrls;
  relatedDates = tmpDates;
}

function ShowRelatedPosts(PostUrl) {
  RemoveDuplicatedPosts(PostUrl);
  var r = Math.floor((relatedTitles.length - 1) * Math.random());
  var i = 0;
  if (relatedTitles.length > 0) {
    document.write('Related Posts: <ul>');
    while (i < relatedTitles.length && i < 5) {
      document.write('<li><a href="' + relatedUrls[r] + '">' + relatedTitles[r] + '</a> - ' + relatedDates[r] + '</li>');
      if (r < relatedTitles.length - 1)
        r++;
      else
        r = 0;
      i++;
    }
    document.write('</ul>');
  }
}
//]]>
</script>
找到下面代码：
<b:if cond='data:post.labels'>
<data:postLabelsLabel/>
<b:loop values='data:post.labels' var='label'>
<a expr:href='data:label.url' rel='tag'><data:label.name/></a><b:if cond='data:label.isLast != "true"'>,</b:if>
</b:loop>
</b:if>
在</b:loop>前加入收集信息的调用，如下所示，其中加粗部分也是控制数量的：
<b:if cond='data:post.labels'>
<data:postLabelsLabel/>
<b:loop values='data:post.labels' var='label'>
<a expr:href='data:label.url' rel='tag'><data:label.name/></a><b:if cond='data:label.isLast != "true"'>,</b:if>
    
    <b:if cond='data:blog.pageType == "item"'>
       <script expr:src='"/feeds/posts/default/-/" + data:label.name + "?alt=json-in-script&callback=RelatedLabels&max-results=10"' type='text/javascript'/>
</b:if>
</b:loop>
</b:if>
在<div class='post-footer-line post-footer-line-3'/>中加入显示部分，如下所示：
<div class='post-footer-line post-footer-line-3'/>
  <b:if cond='data:blog.pageType == "item"'>
    <script type='text/javascript'>ShowRelatedPosts('<data:post.url/>');</script>
  </b:if> </div>
