我现在确实搜索了两天，以找出为什么这个看似简单的 javascript 在我的 Ruby on Rails 应用程序中不起作用。我有以下代码：
<%= link_to "+ nieuw verzoek", :controller => "tickets", :action => "new", :confirm => "are you sure ?" %>
该链接有效，但没有向我显示带有确认问题的弹出屏幕。我不知道为什么。
以下是有关我的应用程序文件的一些信息：
My Gemfile:

Jquery 确实有效。当我创建一个简单的：
<div> <a class="jq" href="#"> test </a></div>
或通过使用这个：
<%= link_to "test",{}, :href => "#",:class => "jq" %>
我可以通过 Jquery 代码来操作这个类的内容。
$(document).ready(function() {
$('.jq').click(function() {
$('.jq').animate(
{
fontSize: '40px'
},
5000
);
});
});
但是当我像这样通过 link_to 生成链接时：
<%= link_to "+ nieuw verzoek", :controller => "tickets", :action => "new", :confirm => "are you sure ?" %>
没有 javascript 正在发挥作用。
希望有人能给我一些指导来解决我的小问题。
谢谢！
