我只是想让我的index.js.erb文件执行警报("hi")命令,但它不起作用。我对铁路很陌生,我想知道你们能不能帮我一下!servers_controller.rb索引方法似乎没有正确执行format.js。有什么建议/想法吗?
服务器控制器.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
alert("hi");
$("#comments").fadeOut();
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">
<thead>

将浏览器指向/servers.js
,它会显示js,但不会运行,因为它不在脚本标记中。
respond_to
部分只选择一种媒体类型来响应,因此当您查看html页面时,如果您希望包含一些javascript,它需要以某种方式位于脚本标记中的html页面中。index.js.erb格式适用于仅为javascript输出而生成的请求,例如ajax请求。
我知道这个问题很老了,尽管这是解决方案,因为我今天两次偶然发现这个问题,甚至都不记得了;)
根据这篇博客文章,您应该检查您的request type
。必须是JS
。如果您通过AJAX
请求控制器操作,请忽略dataType-attribute
。这将把请求类型设置为*/*
,但它仍然可以工作。
示例:
$.ajax({
url: '/users/auth/facebook/callback',
type: 'GET'
});
编辑
对控制器的请求应该是这样的:
Processing by Users::OmniauthCallbacksController#facebook as JS
用我的解决方案,它看起来像这样:
Processing by Users::OmniauthCallbacksController#facebook as */*
将dataType设置为"JS"对我不起作用,但它仍然可以像JS一样工作。
