在我解釋我的問題之前,我將提供相關代碼的上下文。我有一個與記分牌模型相關的球隊模型。手頭的問題與團隊有關。Ajax「link_to」發送多個請求控制器請求時,點擊的速度非常快(Rails 4)
視角下的團隊指數
<div class="team-list">
<%= render @scoreboard.teams.reject(&:new_record?) %>
</div>
的部分爲@ 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>
我遇到麻煩的link_to是爲編輯方法。
隊#編輯控制器的方法
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_<%[email protected]%>").hide();
$("#team_<%[email protected]%>").before("<%= j render 'teamedit'%>");
現在,解釋疑難問題。我在開發環境中。在完美的世界中,我想點擊link_to進行編輯,並讓特定的團隊div馬上消失(只有這樣我才能再次點擊它)並呈現該團隊的編輯表單。然而,在緩慢加載期間(發生很多),我可以點擊link_to兩到三次,並調用編輯方法的多個控制器請求。這個問題是,Jquery的執行次數也是我點擊的次數最多,同樣的元素是2或3個表單。
例如,這些日誌文件,當我點擊真快上ID爲的link_to的團隊= 50:

呈現的每個請求edit.js.erb所以我結束了兩個形式。 我怎樣才能讓它成爲可能:無論我在點擊「link_to」之前點擊了多少次,它只會生成一個該資源的編輯表單?
嗨鏈接!感謝您的回答。我會將該代碼放入edit.js.erb文件或application.js中嗎? – kpaul
您可以將其添加到application.js或特定於該頁面/控制器的任何自定義js文件中。確保您將其綁定在文檔就緒功能中。 – webster
嘿。謝謝你的幫助。我對自己的代碼做了一些自己的修改,但它絕對是正確的想法。 – kpaul
