我想将自定义RSS Feed显示为水平列表。我正在使用响应式模板并将我的Feed嵌入到该模板中。我相信我的JavaScript并没有将每个RSS帖子分成一个单独的列表项，就像我想的那样。
(function($) {

当我查看页面源时，没有动态创建的html。如何在线显示这些列表项？
Feed以HTML格式显示如下：
<script>
jQuery(function($) {
$("#rss-feeds").rss("http://www.feed43.com/channelfireball.xml", {
limit: 15
})
</script>
<div style="border:none;width:100%;height:auto;overflow-y:scroll;
overflow-x:scroll;">
<div class="span2 item">
<div class="item-wrap">
<div class="post_results" id="rss-feeds"></div>
</div>
</div>
</div>
