select2-rails gem无法在Rails4上运行 [英] select2-rails gem is not working on Rails4

问题描述

我已经尝试过 select2-rails gem 的文档，但我的浏览器控制台仍然抛出错误。

I have tried given documentation for the select2-rails gem, but my browser console still throws an error.

未捕获TypeError：$（...）。select2不是函数

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

我正在使用 rails 4.0.1 & select2-rails 3.5.9.3

I am using 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？感谢任何帮助。

What i am doing wrong here? Any help is appreciated.

推荐答案

问题肯定在 application.js ：根据他们的< a href =https://github.com/argerim/select_2_example/blob/master/app/assets/javascripts/application.js =noreferrer>演示应用，需要JS插件的顺序是如下：

The problem is surely in application.js: According to their Demo App, the sequence of requiring JS plugins is as follows:

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

在您的情况下，您必须加载 turbolinks 之前 select2 ，导致：

In your case, you have to load turbolinks before select2, leading to:

//= 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 .
