在HAML中，如何向表单上的提交输入（按钮）添加类

Question

我都试过了：

= f.submit, :class => "form_submit"

和

= f.submit { :class => "form_submit" }

只需

即可

= f.submit

这是我的完整铁轨表格。

= form_for @organization do |f|
  %div
    .description
      = f.label :description
    = f.text_area :description, :rows => 4, :class => 'ckeditor'
  = f.submit, :class => "form_submit"

Answer 1

那将是

= f.submit 'Button', class: 'custom-class'

如果您想让Rails处理文本，请使用nil

= f.submit nil, class: 'custom-class'

Answer 2

= f.submit 'button_name',:class => "form_submit"
