AJAX不呈現部分

Question

我有一個名爲events\new.html.erb的視圖，其中包含其他用戶的集合選擇。我想這樣做以便每當用戶在收集選擇中選擇一個不同的名稱時，<div id="colleaguecal"></div>就會填滿所選用戶的Calendar，該用戶擁有他們的個人Events。不過，我似乎無法得到部分calendars\_showColleague.html.erb持有我想渲染，實際上出現在集合中選擇改變日曆...

#events\new.html.erb 

<%= f.collection_select :id, 
           Customer.where(business_id: current_customer.business_id), 
           :id, 
           :full_name, 
           { prompt: 'Select' }, 
           { id: "colleageselect", onChange: "renderColCal(this)" } %> 

#application.js 
function renderColCal(select){ 

    var colleagueID = select.value ; //this variable is sent to Ruby for the database query to find the selected user 
    $(document).on("change", "select#id", function(e){ 

      $.get("customers/"+ +$(this).val() + "/calendars/1"); 
     } 
    ); 

} 

..

#routes.rb 
post 'calendars_controller/calendarChange', to: 'calendars_controller#calendarChange' 

然後我採取的JavaScript變種colleagueID和我Calendars_controller#calendarChange使用它：

#calendars_controller.rb 
class CalendarsController < ApplicationController 
    respond_to :js, :html 


    def new 
    @calendar = Calendar.new(calendar_params) 

    end 

    def create 
    @calendar = Calendar.new(calendar_params) 
    end 

private 
    def calendar_params 
    params.require(:customer_id) 
    end 


    def show 
    @calendar = current_customer.calendar 
    @events = @calendar.events 
    end 

    def calendarChange 
    colleagueID = params[:colleagueID] #the JS var is taken in here and then used to find the user in the database 
    @colleague = Customer.where(id: :colleagueID) 

    @colcalendar = @colleague.calendar 
    @events = @colleague.calendar.events #the specific events that I want to render to the '_showColleague.html.erb' template 

    end 

end 

我需要在events\new.html.erb內渲染部分calendars\_showColleague.html.erb，其中_showColleague通過在日曆＃calendarChange中創建的變量@events和@colcalendar。在客戶與collection_select進行交互之前，應該沒有任何內容，然後一旦他們選擇了另一個客戶，所選客戶的日曆（_showColleague）應顯示在下面。我將如何做到這一點？

有人告訴我，這個昨天做的，但它沒有任何渲染：

#app/views/calendars/new.js.erb 
$(".element").html("<%=j render 'calendars/_showColleague' %>"); 

請幫幫忙！謝謝

請參考這一點，請注意，在渲染部分時，您不需要提供_（下劃線）。

$('.element').html("<%= escape_javascript(render :partial => 'calendars/showColleague') %>");
