我的应用程序几乎完成了，现在我正在搞乱化妆品，并决定做一些分页。will_paginate 对我来说没有用，所以我尝试了 Kanimari，它在不使用 Ajax 的时候就可以工作。

我的问题是我的页面有 2 个彼此不同的分页索引，因此使用不同的集合。

使用分页标签上的标签“：remote => true”它不起作用，在我看来，它试图在只点击一个分页时填充两个分页。

我的文件如下

feed.js.erb

$("#myItems").html("<%= escape_javascript(render partial: 'shared/feed_item', collection: @feed_items) %>");
$("#myBids").html("<%= escape_javascript(render partial: 'shared/feed_bid_item', collection: @feed_bids) %>");
$("#paginatorItem").html("<%= escape_javascript(paginate(@feed_items, :remote => true, :param_name => 'feed_items_page').to_s) %>")
$("#paginatorBids").html("<%= escape_javascript(paginate(@feed_bids, :remote => true, :param_name => 'feed_bids_page').to_s) %>")

feed.html.erb

<div class="row span8">
  <h3>Latest Bidded Items</h3>
  <div id="paginatorBid"><%= paginate @feed_bids, :remote => true, :param_name => :feed_bids_page  %> </div>
  <% if @feed_bids.any? %>
      <div id ="myBids" class="microposts">
        <%= render partial: 'shared/feed_bid_item', collection: @feed_bids %>
      </div>
  <% end %>
</div>
<div class="row span8">
  <h3>My Items</h3>
  <div id="paginatorItem"> <%= paginate @feed_items, :remote => true, :param_name => :feed_items_page %>  </div>
  <% if @feed_items.any? %>
      <div id="myItems" class="microposts">
        <%= render partial: 'shared/feed_item', collection: @feed_items %>
      </div>
  <% end %>
  <div id="paginatorItem"> <%= paginate @feed_items, :remote => true, :param_name => :feed_items_page %>  </div>
</div>

页面控制器'

class StaticPagesController < ApplicationController
  def home
    if signed_in?
      @items  = current_user.items.build
      @feed_items = current_user.feed.page(params[:feed_items_page]).per(10)
      @feed_bids = current_user.bid_feed.page(params[:feed_bids_page]).per(2)
    end
  end

  def help
  end

  def about
  end

  def contact
  end

  private

end

我在 firebug 的控制台上得到的错误是：

当我点击它时，网址也不会改变......

有什么想法吗？

您是否有理由将“.to_s”附加到您的 javascript 调用中？尝试改变：

$("#paginatorItem").html("<%= escape_javascript(paginate(@feed_items, :remote => true, :param_name => 'feed_items_page').to_s) %>")
$("#paginatorBids").html("<%= escape_javascript(paginate(@feed_bids, :remote => true, :param_name => 'feed_bids_page').to_s) %>")

至

$("#paginatorItem").html("<%= j paginate(@feed_items, :remote => true, :param_name => 'feed_items_page') %>")
$("#paginatorBids").html("<%= j paginate(@feed_bids, :remote => true, :param_name => 'feed_bids_page') %>")
