我在下面的代码中遇到了syntaxt错误。

有人可以帮助我。

  <%= button_tag :class => 'pull-right margin-clear btn btn-sm btn-default-transparent btn-animated notify-class', :type => :submit,
      :id =>"notify-class<%=product.master.id%>" :style=>'display:none'    
      :data-toggle => "modal" , :data-target => "#myModal" >         
        Notify me!<i class="fa fa-bell" style ="margin-left: 10px;"></i>
  <% end %>

Answer 1

您之前缺少逗号：style和before：data-toggle - 这是更正后的代码：

<%= button_tag :class => 'pull-right margin-clear btn btn-sm btn-default-transparent btn-animated notify-class', :type => :submit,
      :id =>"notify-class<%=product.master.id%>", :style=>'display:none',    
      :data-toggle => "modal" , :data-target => "#myModal" >         
        Notify me!<i class="fa fa-bell" style ="margin-left: 10px;"></i>
  <% end %>

Answer 2

首先，您需要在do：

的末尾加button_tag

<%= button_tag :class => 'pull-right margin-clear btn btn-sm btn-default-transparent btn-animated notify-class', :type => :submit,
  :id =>"notify-class<%=product.master.id%>" :style=>'display:none'    
  :data-toggle => "modal", :data-target => "#myModal" do %>         
    Notify me! <i class="fa fa-bell" style ="margin-left: 10px;"></i>

其次，您需要修复"notify-class<%=product.master.id%>"。我不确定您在此处尝试做什么，但您在现有＆lt;％=％＆gt;中注入了<%= %>个ERB标记。为你的button_tag。如果您尝试插入字符串，请使用："notify-class#{product.master.id}"，只要定义了product，该工作就会有效。
