Element.update不是函数[Rails 3 + JQuery] [英] Element.update is not a function [Rails 3 + JQuery]

问题描述

我正在尝试将JQuery集成到Rails 3中.我已经从下载了rails.js文件. http://github.com/rails/jquery-ujs 并将其包含在我的应用程序中.我还包括了JQuery.

I'm attempting to integrate JQuery into Rails 3. I've downloaded the rails.js file from http://github.com/rails/jquery-ujs and have included it in my app. I've also include JQuery.

但是当我尝试做一个简单的page.replace像这样:

But when I attempt to do a simple page.replace like so:

render :update do |page|
  page.replace_html "my_div", :partial => "my_partial", :locals => {:mylocal => mylocal}
end

我从正在执行的javascript中抛出以下错误:

I get the following error thrown from the javascript executing:

RJS error:
TypeError: Element.update is not a function

Element.update("my_div", "mypartialdata");

有什么想法吗?

推荐答案

正如其他人所说的，page.replace在rails 2中引用Element.update.

As others have said, page.replace, in rails 2, references Element.update.

如果您希望在带有jQuery的Rails 3中使用相同的助手，请查看jrails:

如果要在Rails 3中使用assert_select_rjs测试助手，请在此处获取已修补的版本:
