ruby-on-rails - 如何使用haml和rails设置数据属性？

Question

我可以有

%a{href: '#', data_toggle_description_length: 'toggle_me_ajax'}

它给我强调不是破折号，即

<a href="#" data_toggle_description_length="toggle_me_ajax"></a>

但是我想拥有HTML5 data-属性，即

<a href="#" data-toggle-description-length="toggle_me_ajax"></a>

但是当我尝试用破折号替换下划线时，即

%a{href: '#', data-toggle-description-length: 'toggle_me_ajax'}

我收到语法错误:

/home/durrantm/Dropnot/webs/rails_apps/linker/app/views/links/_links.html.haml:13: syntax error, unexpected tLABEL

Answer 1

尝试这个:

%a{"data-toggle-description-length" => "toggle_me_ajax", href: "#"}

或

%a{href: "#", :data => {:toggle_description_length => "toggle_me_ajax"}}

您还可以使用在线提供的 html2haml converter

编辑:

如评论中所述，还有其他两种语法可以使用

 %a{href: "#", { "data-toggle-description-length": "toggle_me_ajax" }}

要么

%a{href: "#", { :"data-toggle-description-length" => "toggle_me_ajax" }}

我仍然更喜欢前两个，因为我认为后两个看起来很丑，有点凌乱。
