Question

我已经检查了这个question on SO，因为我遇到类似rails的问题。我试图让AJAX请求工作（查找一些金融代码），我认为我的代码（至少我希望）没问题，但我仍然得到这个奇怪的错误：

bootstrap.self-fdc98dee79ee88255e10cac6caa91338165cb76cf0d263744d8d90011fc2ef8f.js：3未捕获TypeError：$（...）。popover不是函数在HTMLDocument。（bootstrap.self-fdc98dee79ee88255e10cac6caa91338165cb76cf0d263744d8d90011fc2ef8f.js：3）在火上（jquery.self-bd7ddd393353a8d2480a622e80342adf488fb6006d667e8b42e4c0073393abee.js：3233） at Object.fireWith [as resolveWith]（jquery.self-bd7ddd393353a8d2480a622e80342adf488fb6006d667e8b42e4c0073393abee.js：3363）在Function.ready（jquery.self-bd7ddd393353a8d2480a622e80342adf488fb6006d667e8b42e4c0073393abee.js：3583）在HTMLDocument.completed（jquery.self-bd7ddd393353a8d2480a622e80342adf488fb6006d667e8b42e4c0073393abee.js：3618）

这是我的剧本：

var init_stock_lookup;

init_stock_lookup = function() {
  $('#stock-lookup-form').on('ajax:success', function(event, data, status) {
    $('#stock-lookup').replaceWith(data);
    init_stock_lookup();
  })
}

$(document).ready(function() {
  init_stock_lookup();
})

这是页面：

<div id="stock-lookup">
  <h3>Search for stocks</h3>
  <%= form_tag search_stocks_path, remote: true, method: :get, id: 'stock-lookup-form' do %>
    <div class="form-group row no-padding text-center col-md-12">
      <div class="col-md-10">
        <%= text_field_tag :stock, params[:stock], placeholder: "Stock ticker symbol", autofocus: true, class: 'form-control search-box input-lg' %>
      </div>
      <div class="col-md-2">
        <%= button_tag(type: :submit, class: "btn btn-lg btn-success") do %>
          <i class="glyphicon glyphicon-search"></i> Look up a stock
        <% end %>
      </div>
    </div>
  <% end %>
  <% if @stock %>
    <div id='stock-lookup-results' class="well results-block">
      <strong>Symbol:</strong> <%= @stock.ticker %>
      <strong>Name:</strong> <%= @stock.name %>
      <strong>Price:</strong> <%= @stock.price %>
    </div>
  <% end %>

我正在使用RoR和Bootstrap（twitter）。我从之前提供的SO链接中理解的是，我有jQuery冲突，但我不知道在哪里，最重要的是，如何修复它......

像往常一样感谢你的帮助！

------编辑。 ----------- 这是我的application.js的参考文献（我添加了//要求twitter / bootstrap行感谢Hieu的答案）。

// This is a manifest file that'll be compiled into application.js, which will include all the files
// listed below.
//
// Any JavaScript/Coffee file within this directory, lib/assets/javascripts, or any plugin's
// vendor/assets/javascripts directory can be referenced here using a relative path.
//
// It's not advisable to add code directly here, but if you do, it'll appear at the bottom of the
// compiled file. JavaScript code in this file should be added after the last require_* statement.

Answer 1

您必须将//= require twitter/bootstrap添加到application.js

中

...
//= require rails-ujs
//= require jquery
//= require jquery_ujs
//= require twitter/bootstrap
//= require turbolinks
//= require_tree .
...
