我只是想让我的index.js.erb文件执行一个警告(“hi”)命令,但它无法正常工作。我对rails非常陌生,我想知道你们是否可以帮助我!看起来servers_controller.rb索引方法没有正确执行format.js。有什么建议/想法吗?
servers_controller.rb
def index
@servers = Server.all
update_all_servers #calls the method update_all_servers in application_controller.rb
respond_to do |format|
format.html # index.html.erb
format.json { render json: @servers }
format.js #index.js.erb
end
end
index.js.erb的
alert("hi");
$("#comments").fadeOut();
的index.html
<%- model_class = Server.new.class -%>
<div class="page-header">
<h1><%=t '.title', :default => model_class.model_name.human.pluralize %></h1>
</div>
<table class="table table-striped">

将您的浏览器指向/servers.js
,它将显示js,但不会运行,因为它不在脚本标记中。
respond_to
部分选择一种且只有一种媒体类型进行响应,因此当您查看html页面时,如果您想要包含一些javascript,则需要在脚本标记的html页面中不知何故。 index.js.erb格式适用于仅针对javascript输出的请求,例如ajax请求。

我知道这个问题已经过时了,虽然这是解决办法,因为我今天两次偶然发现了这个问题,甚至没有记住;)
根据this博文,您应该查看request type
。它必须是JS
。如果您通过AJAX
请求控制器操作,请忽略dataType-attribute
。这会将请求类型设置为*/*
,但它仍然有效。
示例:强>
$.ajax({
url: '/users/auth/facebook/callback',
type: 'GET'
});
修改强>
对控制器的请求应如下所示:
Processing by Users::OmniauthCallbacksController#facebook as JS
使用我的解决方案,它将如下所示:
Processing by Users::OmniauthCallbacksController#facebook as */*
将dataType设置为'JS'对我来说不起作用,但它仍然可以像JS一样工作。
