Rails jQuery移动路由/渲染问题 [英] Rails jquery mobile Routing/Rendering Issue
问题描述
我正在按照教程 http://fuelyourcoding.com /getting-started-with-jquery-mobile-rails-3/将简单的脚手架Rails 3应用程序中的视图转换为jquery移动前端.
I'm following a tutorial http://fuelyourcoding.com/getting-started-with-jquery-mobile-rails-3/ transforming the views in a straightforward scaffolded Rails 3 application into a jquery mobile front end.
创建新记录后，我将传递到show视图，并实际上看到show视图的结果，如显示在记录的两个新创建的字段中一样，但是URL为
After I create a new record I'm passed to the show view and actually see the results of the show view as in the two newly created fields of the record are shown, however, the URL is http://localhost:3000/currencies in the browser. And when I view the source, the source is actually the index view not the show view that is rendered in the browser, which is rather bizarre. Any ideas why this is happening?
宝石文件:
source 'http://rubygems.org'
gem 'rails', '3.0.10'
# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'
gem 'sqlite3'
gem 'jquery-rails'
路线:
Mycurrency::Application.routes.draw do
resources :currencies
#match ':name' => 'Currencies#show', :as => 'currency_name'
root :to => 'currencies#index'
控制器:

推荐答案
jQuery Mobile通过AJAX加载页面，将页面添加到DOM，然后通过所有jQuery Mobile样式进行增强.由于这种通过AJAX加载页面的方法，因此当用户在站点中导航时，页面的源不会改变.
jQuery Mobile loads pages via AJAX, adds them to the DOM, and then enhances them with all the jQuery Mobile styling. Because of this method of loading pages via AJAX, the source for the page does not change as a user navigates around the site.
要查看当前页面的源代码，您需要刷新网页.
To view the source code for the current page you need to refresh the webpage.
我建议阅读AJAX导航的jQuery Mobile文档: http: //jquerymobile.com/demos/1.0rc2/docs/pages/page-navmodel.html
I recommend reading the jQuery Mobile Documentation for AJAX Navigation: http://jquerymobile.com/demos/1.0rc2/docs/pages/page-navmodel.html
