单击Rails中的按钮后如何在JQuery中调用函数

Question

我想在用户单击按钮之后绘制（ id='dd' ）

<%= image_tag("logo.png", size: "460x69", alt: "hallo", class: "logo") %>
<h1 class="main_title"><center>WOrld</center></h1>


<div >
  <p class="mod1_title">Modul</p>
  <div class="mod1_boxed">
    <strong>Energy (kWh):</strong> <a href="#"><img src="infoicon.png" class="info"></img></a>
      <%= form_tag( '/calculation/index', post: true ) do %>
      <%= text_field_tag "user_entry_module1", nil, placeholder: "Bsp. 3500", id: "user_entry" %></br>

      <strong>PV (kWp):</strong></br>
      <%= text_field_tag "user_entry_module2", nil, placeholder: "Bsp. 5", id: "user_entry_2" %></br>
      <%= submit_tag "Berechnen", id: "dd"%>

      <%end%>
  </div>  
</div>

<div id="container" style="min-width: 410px; max-width: 800px; height: 400px; margin-left: 150px; margin-top: 0px;"></div>




<%-# Reading data from the Front-End -%>
<%= javascript_tag do %>
  window.a = '<%= params[:user_entry_module1].to_i %>';
  window.b = '<%= params[:user_entry_module2].to_i %>';  
<% end %>



<script >

  $(function(){

    // Converting entries by user to integer
    var myInteger1; 
    myInteger1 = parseInt(a); 
    var myInteger2; 
    myInteger2 = parseInt(b);
    sum = myInteger1 + myInteger2; 
    console.log("Summe von entries:"+sum);




    // Calling my API with AJAX
    $('#dd').click(function(){

      $.ajax({ 
      type: 'POST', 
      url: '/api/v2/energycalcsb', 
      data: {"data":[myInteger1,myInteger2]}, 
      dataType: 'json', 
      success: function(data){ //Sending the output to a function
        send_to_front(data); 
        //console.log('success', data); //Help to print the output of the API
      }      

      });
       });

      // Function which receives the data from AJAX and the plot them with Highcharts

        var outputs = ['discharge_kWh', 'charge_kWh', 'purchase_kWh', 'feeding_kWh', 'own_consumption_kWh', 'own_production_kWh'];

        for (var i=0;i<=5;i++)

我已经尝试过click（）事件，但是它不起作用。 它不绘制任何内容，当此事件不存在时，则仅在加载网页时才具有图表。 有什么想法吗？

Answer 1

我在调用图表（ #container ）之前用if来解决它。 我不知道我可以在$(function(){....});混合使用JQuery和javascript $(function(){....});
