Twitter Jquery小部件:创建无效的URLS

标签: javascript jquery twitter

我的网站上有一个推特小部件。唯一的问题是,当您点击“约5小时前”时,它会为链接创建无效的网址。

示例:如果您点击最近的推文,则会转到此链接,该链接无效:http://twitter.com/#!/ohshititsjake/statuses/63741419709411330

正确的网址是: http://twitter.com/#!/ohshititsjake/statuses/63741419709411328

以下是我认为是问题的脚本部分:

` function build_url() {
      var proto = ('https:' == document.location.protocol ? 'https:' : 'http:');
      if (s.list) {
        return proto+"//api.twitter.com/1/"+s.username[0]+"/lists/"+s.list+"/statuses.json?per_page="+s.count+"&callback=? ";
      } else if (s.query == null && s.username.length == 1) {
        return proto+'//api.twitter.com/1/statuses/user_timeline.json?screen_name='+s.username[0]+'&count='+s.count+'&callback=?';
      } else {
        var query = (s.query || 'from:'+s.username.join(' OR from:'));
        return proto+'//search.twitter.com/search.json?&q='+escape(query)+'&rpp='+s.count+'&callback=?';
      }
    }
`

以下是完整的javascript:

  $.fn.tweet = function(o){
    var s = {
      username: ["ohshititsjake"],

查看该用户帐户上的固定链接ID,它们与您在帖子中生成的ID不匹配。答案可能在这篇文章中:

Why a wrong tweet id is returned from twitter API?

所以请尝试更改此行:

var date = '<span class="tweet_time"><a href="http://twitter.com/'+from_user+'/statuses/'+item.id+'" title="view tweet on twitter">'+relative_time(item.created_at)+'</a></span>';

到此:

var date = '<span class="tweet_time"><a href="http://twitter.com/'+from_user+'/statuses/'+item.id_str+'" title="view tweet on twitter">'+relative_time(item.created_at)+'</a></span>';

真的,它只是将item.id更改为该行中间的item.id_str。
