Question

我的所有项目中的资产管道都存在问题，而且我正在试图找出原因

我有一个非常基本的测试javascript函数来测试它

HTML

  <button onclick="myFunction()">Test</button>

的javascript

    function myFunction() {
    alert("I am an alert box!");
}

如果我把它放在视图中的脚本标签中，它可以正常工作。如果我把它放在application.js中它运行正常，但是一旦我尝试添加自己的文件它就不起作用，我试图在供应商中插入的任何插件都是如此。

首先我将它添加到清单

    //= require rails-ujs
//= require turbolinks
//= require home.js
//= require_tree .

然后我将助手添加到我的视图

 <%= javascript_include_tag "home", "data-turbolinks-track" => true  %>

然后我预先编译它并重新启动服务器

Rails.application.config.assets.precompile += %w( home.js )

毕竟，它仍然无法奏效。我一直试图解决这个问题几天，到目前为止没有任何工作，我非常感谢我给予的任何帮助，谢谢你的帮助。

我从删除home的帮助程序并将application.js的帮助程序添加到我的视图中时出错：

rails-ujs.self-661556f443fbae7f6cec8f2cd394aa5e8186cb3f96aded9628126d3484eaa71a.js?body=1:626 Uncaught Error: rails-ujs has already been loaded!

我刚遇到类似的问题。在我的情况下，文件夹app / assets / javascripts中还有一个名为home.coffee的文件，该文件阻止了home.js被rails看到。如果我将文件home.js重命名为test.js（不存在test.coffee）或删除了文件home.coffee，则一切正常。
