Question

我正在使用link_to_remote异步更新div，但它不起作用。我必须刷新页面才能看到变化。

我用它来生成链接。 http://ruby.pastebin.com/m1d83be81


"padding-left:30px", :display => "table-row" ) do %>
 
  { :success => 'entry_' + entry.id.to_s},
           :url =>{ :controller => :entries, :action => :increment ,:id => entry.id},
           :with => "'amount=' +prompt('Amount')")%> 
  { :success => 'entry_' + entry.id.to_s},
           :url =>{ :controller => :entries, :action => :decrement ,:id => entry.id},
           :with => "'amount=' +prompt('Amount')")%> 
 { :success => 'entry_' + entry.id.to_s},
           :url =>{ :controller => :entries, :action => :update ,:id => entry.id},
           :with => "'amount=' +prompt('Amount')")%>

相应的操作都是这样的：


  def increment
    @entry = Entry.find(params[:id])
    @entry.amount += params[:amount].to_i
    @entry.save!
    render :partial=>"entry", :object=>@entry
  end

Answer 1

删除update子句中的：success标记并测试：

:update => 'entry_' + entry.id.to_s

Answer 2

我发现在控制器操作中指定要更新的div是有帮助的。

link_to_remote不更新div
