我正在使用来自Twitter Bootstrap和HAML的“按钮下拉列表”。在Bootstrap文档中,我找到了示例:
<div class="btn-group">
<a class="btn dropdown-toggle" data-toggle="dropdown" href="#">
Action
<span class="caret"></span>
</a>
<ul class="dropdown-menu">
<!-- dropdown menu links -->
</ul>
</div>
我尝试使用HAML重写它:
%div{:class => 'btn-group task_controller'}
%a{:class => 'btn-mini dropdown-toggle', "data-toggle" => 'dropdown', :href => '#'} Action
%span{:class => 'caret'}
%ul{:class => 'dropdown-menu'}
%a{:class => 'close_task', :name => task.name, :href => '#' } Close
但收到了错误消息:
Haml::SyntaxError - Illegal nesting: content can't be both given on the same line as %a and nested within it.
所以Bootstrap说我把元素放在-tag中,但是HAML不允许这样做。我该如何解决这个问题?

问题在于以下几点:
%a{:class => 'btn-mini dropdown-toggle', "data-toggle" => 'dropdown', :href => '#'} Action
%span{:class => 'caret'}
错误消息:content can't be both given on the same line as %a and nested within it
是指Action
的内容“与%a在同一行”,而%span{:class => 'caret'}
是内容“嵌套在其中”。
更一般地说,也许更容易看到,你不能有这样的东西:
%tag Some content here
And something here as well
修复方法是在%a
:
%a{:class => 'btn-mini dropdown-toggle', "data-toggle" => 'dropdown', :href => '#'}
Action
%span{:class => 'caret'}
这给出了所需的输出:
<a class='btn-mini dropdown-toggle' data-toggle='dropdown' href='#'>
Action
<span class='caret'></span>
</a>

不要忘记你的汉语成语!
#div{:class => 'btn-group task_controller'}
相当于:
.btn-group.task_controller
...等

试试这个:
%div{:class => 'btn-group task_controller'}
%a{:class => 'btn-mini dropdown-toggle', "data-toggle" => 'dropdown', :href => '#'}
Action
%span{:class => 'caret'}
%ul{:class => 'dropdown-menu'}
%a{:class => 'close_task', :name => task.name, :href => '#' } Close
只有当标签中没有更多内容行时,标签名称和内容才能在同一行。
