一个常见的组合搜索功能。
假设:Search页——>显示搜索Form
     Result页——>显示结果,有翻页功能

我实现的方法比较笨,在Result页使用了一个隐藏Form。

不知道大家有什么简单的方法?

隐藏的form是用来干吗的?

没说清楚,

通过Hidden Form传递搜索项参数,因为result页只显示结果。

可以看看我的 railsgacl 中关中 Acl List 的功能

我在里面写了一个 分页的 helper

谢谢,我想知道参数怎么传递给分页的链接

Form (search page)——> params (results page)

怎么直接把params传递给分页的链接呢?

个人不喜欢用hidden form翻页
虽然后面没什么参数,但是上网的人大部分都习惯把自己喜欢的页面直接复制地址栏的url给别人看
这样翻页,参数等都不存在了,失去share的意思(当然,内部系统除外)

表单用get方式提交(虽然有url长度限制,不过一般情况下谁也不会闲的没事翻页传递非常长的参数吧),params都在url里.

如果想偷懒,可以写个小函数,自动'继承'url的所有参数,把page部分替换成上一页下一页的数字就可以了.

我很懒,写的js(这样就是对搜索引擎友好度差了点).也可以写成服务器端的函数调用好了.

# Methods added to this helper will be available to all templates in the application.
module ApplicationHelper

  def page_leaf(now_page, max_page, options = {}, page_size = nil, line_size = 10)
    if options.is_a?(String)
      "Page Error!"
    else
      str = ['<div class="fenye_Div">']
      line_size = line_size+1 if line_size%2 == 0
      if now_page > 1
          options['page'] = 1

        for i in max_page-4..max_page
          if (i==now_page)
            str << "<span>[#{i}]</span>"
          else

            options['page'] = i
            str << (link_to "#{i}", options)
          end
        end
      elsif (max_page <= line_size)

          end
        end
      else
        for i in 1..max_page
          if ((i>now_page-(line_size/2 + 1)) && (i<now_page+(line_size/2 + 1)))
            if (i==now_page)
              str << "<span>[#{i}]</span>"
            else
              options['page'] = i
              str << (link_to "#{i}", options)
            end
          end
        end
      end
      if (now_page < max_page)
        options['page'] = now_page+1
        str << (link_to '下一页', options)
      else
        str << '下一页'
      end
      if (max_page > 1 && max_page != now_page)
        options['page'] = max_page
        str << (link_to '最后页 &raquo;', options)
      else
        str << ' ... 最后页 &raquo;'
      end
      str << '</div>'
      str.join('&nbsp;')
    end
  end

end

调用:
<%= page_leaf @page, @max_page, :id => @group.id, :type => @type %>

<%= page_leaf @page, @max_page, :filter_aco_section => @params[:filter_aco_section]||'', :filter_aco => @params[:filter_aco]||'', :filter_aro_section => @params[:filter_aro_section]||'', :filter_aro => @params[:filter_aro]||'', :filter_aro_group => @params[:filter_aro_group]||'', :filter_axo_section => @params[:filter_axo_section]||'', :filter_axo => @params[:filter_axo]||'', :filter_axo_group => @params[:filter_axo_group]||'', :filter_acl_section => @params[:filter_acl_section]||'', :filter_return_value => @params[:filter_return_value]||'', :filter_allow => @params[:filter_allow]||'', :filter_enabled => @params[:filter_enabled]||'', :submit => @params[:submit]||'' %>
