使用erb和Ruby块语法进行JSX集成反应 [英] React JSX integration with erb and Ruby block syntax
问题描述
在我的 app / assets / javascripts / components / navbar.js.jsx.erb
中,我可以在组件的render函数中编写类似的代码(使用宝石反应轨道):
< pre class = lang-js prettyprint-override>
类Navbar扩展了React.Component {
render(){
return(
< div className = navbar -header>
< ul>
< li>
<%= link_to root_path,className:'navbar-brand'do%>
< span className ='glyphicon glyphicon-home'< / span>
& nbsp;
<%= I18n.t('menu.now')%>
< %end%>
< / li>
< li><%= link_to I18n.t('menu.archive'),archive_path%< // li>
< / ul>
< / div>
);
}
}
除 link_to
带块,这给了我一个语法错误:
语法错误,意外的keyword_end,期望') '
如果我删除该块,则一切正常。知道吗?
PS:要使用Rails助手,我已经在 config / initializers / assets.rb $ c $中添加了这些行c>:
#在资产管道中包括Rails帮助器
Rails.application.config.assets.configure do | env |
env.context_class.class_eval做
包括ActionView :: Helpers
包括Rails.application.routes.url_helpers
结束
结束

In my app/assets/javascripts/components/navbar.js.jsx.erb
I can write something like this in the render function of my component (I'm using the gem react-rails):
class Navbar extends React.Component {
render() {
return(
<div className="navbar-header">
<ul>
<li>
<%= link_to root_path, className: 'navbar-brand' do %>
<span className='glyphicon glyphicon-home'></span>
<%= I18n.t('menu.now') %>
<% end %>
</li>
<li><%= link_to I18n.t('menu.archive'), archive_path%></li>
</ul>
</div>
);
}
}
All works fine except for the link_to
with block, which gives me a syntax error:
syntax error, unexpected keyword_end, expecting ')'
If I remove the block all works fine. Any idea?
PS: To use the Rails helpers, I have added these lines in config/initializers/assets.rb
:
# Include Rails helpers in the assets pipeline
Rails.application.config.assets.configure do |env|
env.context_class.class_eval do
include ActionView::Helpers
include Rails.application.routes.url_helpers
end
end
