为什么相关的帖子小部件只出现在页脚部分，而不出现在侧边栏中？

Question

我正在为我的 Blogger 博客使用相关的帖子小部件。 当我在页脚中安装小部件时，它会正确显示，但是当我尝试在侧边栏中显示它时，会出现提示 - 只出现一个空白小部件。

这是我正在使用的代码，为什么小部件没有显示？：

 <;--RelatedPostsStarts--> <script language='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 < 6) { 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>

Answer 1

这是因为<data:post.url/> （在您的第二个 JavaScript 中）应该放在Blog1小部件中。

尝试将以下代码放在侧边栏中：

<b:if cond='data:blog.pageType == &quot;item&quot;'>
    <div id='related-posts'>
        <b:loop values='data:post.labels' var='label'>
            <b:if cond='data:label.isLast != &quot;true&quot;'>
            </b:if>
            <b:if cond='data:blog.pageType == &quot;item&quot;'>
                <script expr:src='&quot;/feeds/posts/default/-/&quot; + data:label.name + &quot;?alt=json-in-script&amp;callback=related_results_labels&amp;max-results=5&quot;' type='text/javascript'/>
            </b:if>
        </b:loop>
    </div>
</b:if>

并且此代码在您帖子的页脚中（在<data:post.body/>下方）：

<script type='text/javascript'>
var currentposturl=&quot;<data:post.url/>&quot;;
var maxresults=5; // Increase To Show More Then 5 Related Post
removeRelatedDuplicates();
printRelatedLabels();
</script>

如果此方法仍然不起作用，则可能您需要使用另一个相关的帖子小部件，该小部件可以放置在 Blog1 小部件之外（有点难找）或 append 使用 JS 将相关帖子的innerHTML放置到侧边栏。
