Question

我想在rails app中将用户glyphicon添加到我的登录输入框中，我目前正在使用Rails 4.2.3和Ruby 2.2.0

我试图搜索这个已经有一段时间但是还没有找到如何将它添加到rails应用程序并且希望我的代码尽可能保持ruby并且如果可能的话（如果不是我想html就足够了）但我很乐意学习如何在rails语法中做到这一点。

任何帮助将不胜感激。

到目前为止，我的输入字段看起来像这样。

<div class="input-group input-group-lg">
    <%= f.label :email %><br />
    <%= f.email_field :email, autofocus: true %>
</div>

如果可能的话，我会喜欢左边的字形和输入框右边的占位符。

Answer 1

<%= button_tag raw("<i class='srch-control-icon-srch'></i> search"), class: "button round" %>
