jQuery在Rails 3.2.8上不起作用 [英] jQuery not working on Rails 3.2.8

问题描述

我在Rails 3.2.8上遇到了jQuery问题.我已经安装了jquery-rails gem，并且我的application.js具有以下内容:

I'm having an issue with jQuery on Rails 3.2.8. I've installed the jquery-rails gem and my application.js has the following:

//= require jquery
//= require jquery_ujs
//= require_tree .

views/layouts/application.html.erb具有

views/layouts/application.html.erb has

<%= javascript_include_tag "application" %>

test.js中的简单Javascript测试:

A simple Javascript test in test.js:

if (jQuery) {
alert('Jquery is loaded')
} else {
alert ('Jquery is not loaded')
}

给了我一个警报，告诉我确实确实加载了jQuery.

gives me an alert telling me that jQuery is indeed loaded.

但是，没有jQuery命令可以使用，即使基本的命令也没有响应:

However, no jQuery commands will work, even basic ones are unresponsive:

$(document).ready(function(){
 $("a").click(function(event){
 alert("Thanks for visiting!");
});
});

我已经尝试了所有方法-甚至通过Google API包括了jQuery.关于可能发生的事情有什么想法吗?

I've tried everything -- even reincluding jQuery through the Google API. Any ideas on what might be going on?

推荐答案

已修复！

在application.html.erb中，我从以下位置更改了这两行的顺序:

in application.html.erb, I changed the ordering of these two lines from:

<%= stylesheet_link_tag    "application", :media => "all" %>
<%= javascript_include_tag "application" %>

收件人:

<%= javascript_include_tag "application" %>
<%= stylesheet_link_tag    "application", :media => "all" %>

现在可以使用了！我不太确定为什么会有人解释?

Now it works! I'm not quite sure why though, can anybody explain?
