Rails 3 渲染 JS 不执行任何操作
我是一个巨大的初学者,我正在学习 Rails 3 和 RJS 请求并进行一些练习。 我正在使用从教程中获得的以下内容进行 RJS 测试。
以下是我的index.rhtml。在我的标题中,我有一些我注意到人们发布的标签,例如 javascript_include_tag 和 csrf_meta_tag
<div id="rjs">I will be updated.</div>
以下行肯定是不正确的。这可能是我的问题。我见过不同的 Rails 2 实现,但我读到在 Rails 3 中它已经发生了变化,并且似乎无法让它工作。我的网址有问题。我无法正确设置我的 url 语句,这可能是问题所在。
<%= link_to "Test out RJS!", rjs_path(@rjs), :remote => true %>
我的 hello.rjs 文件具有以下内容
page.replace_html "rjs", "<b>See!</b>"
我的控制器如下
class RjsController < ApplicationController
def hello
end
从我遵循的指南中,当您单击链接时,应将原始的“我将更新”切换为“查看”,但在我的情况下,当我单击链接时没有任何反应 。
有人能够帮助我处理我的 link_to 行,并可能给我一个解释,为什么它是这样写的 谢谢
I am a huge beginner and I am learning and doing some practice work with rails 3 and RJS requests.
I am doing a RJS test with the following which I got from a tutorial.
The following is in my index.rhtml. In my header I have the tags I have noticed people post around such as teh javascript_include_tag and csrf_meta_tag
<div id="rjs">I will be updated.</div>
The Following line is for sure incorrect. Which is probably my problem. I have seen different rails 2 implementations but I've read that in Rails 3 it has changed and can't seem to get it working. My Url is the problem. I can't set up my url statment correctly which is probably the problem.
<%= link_to "Test out RJS!", rjs_path(@rjs), :remote => true %>
My hello.rjs file has the following
page.replace_html "rjs", "<b>See!</b>"
My controller is the following
class RjsController < ApplicationController
def hello
end
From the guide I was following this should switch the original "I will be updated" to "See" when you click the link but in my case nothing happens when I click the link
end
Would someone be able to help me with my link_to line and possibly give me a explanation as too why it is written the way it is. Thank You

您可以像这样在控制器顶部添加
:respond_to
吗?希望有效。
Can you add
:respond_to
on top of your controller like this?Hope that works.
我正在使用 JQuery 和 JRails 并在 firefox 中检查它告诉我 JQuery 未定义。我认为我在 Rails 应用程序中的所有设置都正确。抱歉,我是该网站的新手。另外放置 respond_to :js 并没有改变任何东西
我的错误让我看到了我在为 JQuery 添加 Unbotrusive 脚本适配器的适配器时覆盖的 Rails.js 行
I am using JQuery and JRails and checking in firefox it tells me JQuery is not defined. I thought I set everything up in my rails app correctly. Sorry I am new to the site. Also putting respond_to :js did not change anything
My error brings me to this line of my rails.js that i overwritten when adding the adapter for Unbotrusive scripting adapter for JQuery
