Rails的使用Ajax时返回一些重复的记录 [英] Rails returning several duplicate records when using Ajax

问题描述

所以，我有一个应用程序，有一些影片剪辑，用户可以搜索特定主题等等...我使用Ajax来处理分页，以便用户可以进行搜索查询，滚动查看更多结果（类似推特）。

So, I have an app that has several movie clips and users can search for specific topics etc... I'm using Ajax to handle pagination so that users can make a search query and scroll to view more results (similar to twitter).

问题是，当IE浏览器滑稽一堆记录用户的搜索将拿出，并为用户向下滚动阿贾克斯将加载的记录与新记录很长的重复。

The issue is when a user searches for i.e. "Funny" a bunch of records will come up and as the user scrolls down Ajax will load duplicates of the records a long with new records.

这里的code：

if $('.pagination').length
  $(window).scroll ->
    url = $('.pagination .next_page').attr('href')
    if url && $(window).scrollTop() > $(document).height() - $(window).height() - 50
      $('.loader').removeClass('hidden')
      $.getScript(url)
  $(window).scroll()

我怎样才能起价在这种情况下重复记录p $ pvent轨道？我试过uniq的和一些其他方法都无济于事。

How can I prevent rails from duplicating records in this case? I've tried uniq and several other methods to no avail.

谢谢！

更新这里的一些额外的code可能有助于调试这样的：

推荐答案

确认要更换的内容，而不是追加另一组的结果，以现有的在你的.js.erb

Make sure you are replacing contents instead of appending another set of results to existing ones in your .js.erb
