Question

我是jQuery的新手。我想更新视图而不刷新页面。数据正在控制台中登录，但没有刷新就无法加载到View中。 $（'＃ajax'）。html（ajax）; -什么也没给我看。我叫数据AJAX。

JavaScript

<script>
$(document).ready(function() {
  $('#api_key').click(function() {

    var request = $.ajax({
      url: "/account/settings/api_token",
      method: "POST",
    });

    request.done(function(msg) {

      if (msg['status'] == 'success') {
        var request2 = $.ajax({
          url: "/account/settings/get_all_tokens",
          method: "GET",
        });
        request2.done(function(ajax) {
          $('#ajax').html(ajax);
          console.log(ajax);
        });
        request2.fail(function(jqXHR, textStatus) {
          alert("Request failed: " + textStatus);
        });
      }
    });

    request.fail(function(jqXHR, textStatus) {
      alert("Request failed: " + textStatus);
    });
  });
});
</script>

HTML

<div class="api-cta-container">
   <p> <%= t("account.settings.api.disclaimer_text_html") %></p>
   <button type="button" id="api_key" class="btn btn-default"><%= 
   t("account.settings.api.add_api_key") %></button>
   <%#= link_to t("account.settings.api.add_api_key"), 
   /account/settings/api_tokens, method: :post, class: "btn btn-default" %>
</div>

<table class="table" id="ajax">
<thead>
    <tr>
    <th><%= t("global.name") %> <</th>
    <th><%= t("global.creation_date") %></th>
  </tr>
</thead>
<tbody>
<% @all_tokens.each_with_index do |token, index|%>
<tr>
    <td><%= (index+1) %></td>
    <td><%= token.created_at %></td>
    <button type="button" class="btn btn-default"><%= t("global.edit") %> <i class="fa fa-sort-desc" aria-hidden="true"><i></button>
    </td>
</tr>
<% end %>
</tbody>

控制台中的数据：成功后，这是对象中的数据
