Ajax“link_to”发送多个请求控制器请求时，点击的速度非常快（Rails 4）

Question

在我解释我的问题之前，我将提供相关代码的上下文。我有一个与记分牌模型相关的球队模型。手头的问题与团队有关。

视角下的团队指数

<div class="team-list"> 
    <%= render @scoreboard.teams.reject(&:new_record?) %> 
</div> 

的部分为@ scoreboard.teams

<div class="row team-div" id="team_<%=team.id%>"> 
    <div class="col-xs-3 team-div-1"> <%= team.name %> </div> 

    <%= link_to (edit_scoreboard_team_path(@scoreboard, team)), remote: true do %> 
     <div class="col-xs-6 team-data"> 
     <div class="row"> 
      <div class="col-xs-4 team-div-2"><%= team.win %> </div> 
      <div class="col-xs-4 team-div-2"><%= team.loss %> </div> 
      <div class="col-xs-4 team-div-2"><%= team.tie %></div> 
     </div> 
     </div> 
    <% end %> 

    <div class="col-xs-1 team-div-2"> 
     <%= team.win + team.loss + team.tie %> 
    </div> 

    <div class="col-xs-1 team-div-2"> 
     <% total_games = team.win.to_i + team.loss.to_i + team.tie.to_i %> 
    <% if total_games == 0 %> 
    <%= "N/A" %> 
    <% else %> 
    <%= (team.win.to_i/(total_games).to_f*100).round(2) %><%="%"%> 
    <% end %> 
    </div> 

    <div class="col-xs-1 team-setting"> 
      <i class="fa fa-trash-o fa-lg" aria-hidden="true"></i> 
    </div> 

</div> 

我遇到麻烦的link_to是为编辑方法。

队＃编辑控制器的方法

def edit 
    @scoreboard = Scoreboard.find(params[:scoreboard_id]) 
    @team = @scoreboard.teams.find(params[:id]) 
    respond_to do |format| 
    format.html {redirect_to scoreboard_url(@team.scoreboard_id)} 
    format.js 
    end 
    end 

的edit.js.erb文件

$("#team_<%=@team.id%>").hide(); 
$("#team_<%=@team.id%>").before("<%= j render 'teamedit'%>"); 

现在，解释疑难问题。我在开发环境中。在完美的世界中，我想点击link_to进行编辑，并让特定的团队div马上消失（只有这样我才能再次点击它）并呈现该团队的编辑表单。然而，在缓慢加载期间（发生很多），我可以点击link_to两到三次，并调用编辑方法的多个控制器请求。这个问题是，Jquery的执行次数也是我点击的次数最多，同样的元素是2或3个表单。

例如，这些日志文件，当我点击真快上ID为的link_to的团队= 50：

    Rendered teams/edit.js.erb (5.6ms) 
Completed 200 OK in 30ms (Views: 24.2ms | ActiveRecord: 1.0ms) 

呈现的每个请求edit.js.erb所以我结束了两个形式。 我怎样才能让它成为可能：无论我在点击“link_to”之前点击了多少次，它只会生成一个该资源的编辑表单？

您可以通过使用jQuery禁用首次点击链接来解决此问题。

添加类的链接

<%= link_to (edit_scoreboard_team_path(@scoreboard, team)), remote: true, class: "team-edit-link" do %> 
    ... 
<% end %> 

禁用时，它被点击

$('.team-edit-link').click(function(e) { 
    if($(this).hasClass('disabled')){ 
    e.preventDefault(); 
    } 
    else{ 
    $(this).addClass('disabled'); 
    } 
});
