Dojo + Rails 3.2.8 + CoffeeScript [英] Dojo + Rails 3.2.8 + CoffeeScript
问题描述
我试图在Rails 3.2.8 web应用程序中使用Dojo Toolkit 1.8而不是JQuery，主要是因为缺少一个基于JQuery的完整和可视化的统一部件。遵循以下步骤：
I'm trying to use Dojo Toolkit 1.8 instead JQuery in a Rails 3.2.8 web application, mainly due of the lack of a complete and visually uniform widget based on JQuery. Followed these steps:
- 将dojo，dijit和dojox目录解压缩到app / assets / javascripts
- 已在application.js中更改
// = require_tree。更改为// = require_directory。 - 已编辑的应用程式版面配置（非常不引人注意，只是为了测试效果）
- Unzip dojo, dijit and dojox directories into app/assets/javascripts
- Changed in application.js
//= require_tree .to//= require_directory . - Edited application layout (Not unobtrusive yet... just to effect of testing)
views / layouts / application.html。 erb
views/layouts/application.html.erb
<!DOCTYPE html>
<html>
<head>
<title>Dojo</title>
<%= stylesheet_link_tag 'application' %>
<%= javascript_include_tag 'application' %>
<%= stylesheet_link_tag '/assets/dijit/themes/claro/claro.css' %>
<%= javascript_include_tag "dojo/dojo", :'data-dojo-config' => 'async: true' %>
<%= csrf_meta_tags %>
</head>
<body class='claro'>
<%= yield %>
<script>
require(["dojo/parser", "dojo/ready"], function(parser, ready) {
ready(function() {
parser.parse();
});
});
</script>
</body>
</html>
- 创建了一个名为home的控制器和一个用于索引操作的模板
-
- Created a controller named home and a template to the index action
views / home / index.html.erb
views/home/index.html.erb
<input type="text" required="true" name="bday" id="bday" data-dojo-type="dijit/form/DateTextBox" value=<%= localize(Date.today - 21.days) %> /> <button id="button1" type="button" data-dojo-type="dijit/form/Button">Button 1</button>好吧，Dijit工作不错！但是当我尝试在CoffeeScript文件（assets / javascripts / home.js.coffee）中放置一些dojo代码时，会在Firebug控制台上出现一个ReferenceError：require未定义错误消息。示例代码：
Ok, Dijit works nice! But when I try to put some dojo code within a CoffeeScript file (assets/javascripts/home.js.coffee), a "ReferenceError: require is not defined" error message is raised on Firebug console. Sample code:
require ["dojo/domReady!"], () -> alert('ok')
如果我把/ = require dojo / dojo在上面的代码之前，它运行，但是所有的dojo模块被加载（不仅仅是domReady），并在Firebug上引发一个Error：defineAlreadyDefined。If I put a
//= require dojo/dojobefore the code above, it runs, but all dojo modules are loaded (not just domReady) and a "Error: defineAlreadyDefined" is raised on Firebug.有没有办法调用require函数，而不必重新加载整个dojo.js甚至访问一个dojo全局变量？
Is there any way to call the require function without having to reload the entire dojo.js or even access a dojo global variable?
感谢
推荐答案
这是我的一个滑块，我换了javascripts包含顺序。正确的是：
It was a slip of mine, I swapped the javascripts inclusion order. The correct is:
<%= stylesheet_link_tag '/assets/dijit/themes/claro/claro.css' %> <%= javascript_include_tag "dojo/dojo", :'data-dojo-config' => 'async: true' %> <%= stylesheet_link_tag 'application' %> <%= javascript_include_tag 'application' %>当我试图在coffeescript文件中需要模块时，Dojo尚未加载。
Dojo wasn't loaded yet when I was trying to require modules within the coffeescript file.
感谢您的关注。
