Question

我只想显示一篇文章，但是当我将（0,2）更改为（0,1）时，没有任何内容出现。有快速解决方案吗？

＆＃13;

YUI().use('yql', function(Y){
    var query = 'select * from rss(0,2) where url = "http://rss.cnn.com/rss/money_latest.rss"'
    var q = Y.YQL(query, function(r){
        //r now contains the result of the YQL Query as a JSON
        var feedmarkup = '<div>'
        var feed = r.query.results.item // get feed as array of entries
        for (var i=0; i<feed.length; i++){
            feedmarkup += '<p><a href="' + feed[i].link + '">'
            feedmarkup += feed[i].title + '</a></p>'
            feedmarkup += '<p>' + feed[i].description + '</p>'	
			feedmarkup += '<p><a href="' + feed[i].link + '">'
            feedmarkup += '<span class="more">Read more</span>' + '</a></p>'		
        }		
        document.getElementById('uknews').innerHTML = feedmarkup
    })
})

  <div id="uknews"></div>

我找到了答案并希望这有助于其他人：

YUI().use('yql', function(Y) {

  var query = 'select * from rss(0,1) where url = "http://rss.cnn.com/rss/cnn_world.rss"'
  var q = Y.YQL(query, function(r) {
    //r now contains the result of the YQL Query as a JSON
    var feedmarkup = '<div class="news-feed">'
    var feed = r.query.count > 1 ? r.query.results.item : [r.query.results.item]; // get feed as array of entries
    for (var i = 0; i < feed.length; i++) {
      feedmarkup += '<div class="feed-title"><a href="' + feed[i].link + '">'
      feedmarkup += feed[i].title + '</a></div>'
      feedmarkup += '<div class="feed-description">' + feed[i].description + '</div>'
      feedmarkup += '<div class="feed-link"><a href="' + feed[i].link + '">'
      feedmarkup += '<span class="more">Learn more</span>' + '</a></p>'
    }

    document.getElementById('uknews').innerHTML = feedmarkup
  })
})

.feedflare {
  display: none;
}

div.feed-description {
  display: block;
  max-width: 400px;
  overflow: hidden;
  white-space: nowrap;
  text-overflow: ellipsis;
}

<div id="uknews"></div>

仅在RSS Feed YUI中显示1篇文章
