1、把下面代码放在<head></head>中。其中的"i < 12"是控制文章数量的，建议数值不要太大，以免影响浏览速递。
2、找到下面黑色的代码，在</b:if>与</b:loop>之间，插入如下红色的代码。注意："max-results=12"是控制相关文章的显示数值。<script type="text/javascript">
//<![CDATA[
var relatedTitles = new Array();
var relatedTitlesNum = 0;
var relatedUrls = new Array();
function related_results_labels(json) {
for (var i = 0; i < json.feed.entry.length; i++) {
var entry = json.feed.entry[i];
relatedTitles[relatedTitlesNum] = entry.title.$t;
for (var k = 0; k < entry.link.length; k++) {
if (entry.link[k].rel == 'alternate') {
relatedUrls[relatedTitlesNum] = entry.link [k].href;
relatedTitlesNum++;
break;
}
}
}
}
function removeRelatedDuplicates() {
var tmp = new Array(0);
var tmp2 = new Array(0);
for(var i = 0; i < relatedUrls.length; i++) {
if(!contains(tmp, relatedUrls[i])) {
tmp.length += 1;
tmp[tmp.length - 1] = relatedUrls[i];
tmp2.length += 1;
tmp2[tmp2.length - 1] = relatedTitles[i];
}
}
relatedTitles = tmp2;
relatedUrls = tmp;
}
function contains(a, e) {
for(var j = 0; j < a.length; j++) if (a[j]==e) return true;
return false;
}
function printRelatedLabels() {
var r = Math.floor((relatedTitles.length - 1) * Math.random());
var i = 0;
document.write('<ul>');
while (i < relatedTitles.length && i < 12) {
document.write('<li><a href="' + relatedUrls[r] + '">' + relatedTitles[r] + '</a></li>');
if (r < relatedTitles.length - 1) {
r++;
} else {
r = 0;
}
i++;
}
document.write('</ul>');
}
//]]>
</script>
<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=related_results_labels&max-results=12"' type='text/javascript'/>
</b:if>
</b:loop>
</b:if>
3、找到自己想要显示相关文章的位置，将下面红色代码放进去，保存就OK那了。本例就放在评论前，如下面黑色代码。
<b:if cond='data:blog.pageType == "item"'>
<script type="text/javascript"> removeRelatedDuplicates(); printRelatedLabels(); </script> </b:if>
<div id='comments'>
<a name='comments'/>
<h4>
<b:if cond='data: post.numComments == 1'>
1 条评论:
<b:else/>
<data:post.numComments/> 条评论:
</b:if>
</h4>
<dl id='comments-block'>
<b:loop values='data: post.comments' var='comment'>
<dt class='comment-author' expr:id='"comment-" + data:comment.id'>
<a expr:name='"comment-" + data: comment.id'/>
<b:if cond='data:comment.authorUrl'>
<a expr:href='data:comment.authorUrl' rel='nofollow'><data:comment.author />
4、完成，看看效果吧！
