javascript - simple_form 提示作为工具提示

Question

我正在尝试让我的 simple_form 提示显示为 twitter-bootstrap 工具提示，这样提示仅在用户选择输入字段或将鼠标悬停在输入字段上时出现。

表单项看起来像(在 haml 中):

:ruby 
  title = <<TITLE
    This text is normally hidden and pops up as a bootstrap tooltip 
    only when the user hovers on the input field.
  TITLE
= f.input :opt_out, hint: title 

我的 simple_form 提示的 CSS 和 Javascript 是普通的，所以我想我必须修改 config/initializers/simple_form.rb 初始化文件:

b.use :hint,  :wrap_with => { :tag => :span, :class => :hint }

Answer 1

我是这样解决的:

    :ruby 
      title = <<TIT 
        This text is normally hidden and pops up as a bootstrap tooltip 
only when the user hovers on the input field.
      TIT
      link = link_to "what's this?", "", rel: "tooltip", title: title, data: {placement: "right"}
      label = "Opt out #{link}"
    = f.input :opt_out, label: raw(label)
