javascript - select2-rails gem 不适用于 Rails4

Question

我已尝试为 the select2-rails gem 提供文档, 但我的浏览器控制台仍然抛出错误。

Uncaught TypeError: $(...).select2 is not a function

我正在使用 rails 4.0.1& select2-rails 3.5.9.3

我的application.js

//= require jquery
//= require select2
//= require jquery.ui.accordion
//= require jquery.ui.menu
//= require jquery.ui.datepicker
//= require common
//= require posts
//= require twitter/bootstrap
//= require owl.carousel
//= require turbolinks
//= require vendor_js
//= require_tree .

$(document).ready(function() {
  $("select#team_select").select2();
});

application.css

*= require select2
*= require_self
*= require jquery.ui.accordion
*= require jquery.ui.menu
*= require jquery.ui.datepicker
*= require common
*= require owl.carousel
*= require lazybox
*= require fancybox
*= require owl.theme
*= require 7531339
*= require_tree .
*= require font-awesome

_form.html.erb

<%= f.select(:team_id, @teams.collect {|p| [p.name, p.id]}, {include_blank: "None"}, {id: "team_select"}) %>

我在这里做错了什么？感谢您的帮助。

问题肯定出在application.js:根据他们的Demo App ，需要JS插件的顺序如下:

//= require jquery
//= require jquery_ujs
//= require turbolinks
//= require select2
//= require select2_locale_pt-BR
//= require_tree .

在你的情况下，你必须加载 turbolinks before select2，导致:

//= require jquery
//= require turbolinks
//= require select2
//= require jquery.ui.accordion
//= require jquery.ui.menu
//= require jquery.ui.datepicker
//= require common
//= require posts
//= require twitter/bootstrap
//= require owl.carousel
//= require vendor_js
//= require_tree .
