Question

我仔细地遵循了这些说明：https://github.com/plataformatec/simple_form/wiki/Bootstrap-component-helpers

但是我不断得到的问题是每当我的页面加载时，我的浏览器控制台中都会出现这个JS错误：

Uncaught TypeError: undefined is not a function

围绕这一行：

$('body').tooltip({ selector: "[data-toggle~='tooltip']"});

我认为导致问题的是.tooltip，因为初始化程序似乎正在运行。我可以告诉，因为生成的html具有JS选择器所需的data-toggle属性。

我正在使用bootstrap-sass gem。

这是我的simple_form_bootstrap初始化程序：

SimpleForm.setup do |config|
  config.wrappers :bootstrap, tag: 'div', class: 'control-group', error_class: 'error' do |b|
    b.use :html5
    b.use :placeholder
    b.use :label
    b.use :tooltip

    b.wrapper tag: 'div', class: 'controls' do |ba|
      ba.use :input
      ba.use :error, wrap_with: { tag: 'span', class: 'help-inline' }
      ba.use :hint,  wrap_with: { tag: 'p', class: 'help-block' }
    end
  end

  # Truncated for brevity

  config.default_wrapper = :bootstrap
end

这是我的simple_form_components.rb初始化程序：

module SimpleForm 
  module Components
    module Tooltips
      def tooltip
        unless tooltip_text.nil?
          input_html_options[:rel] ||= 'tooltip'
          input_html_options['data-toggle'] ||= 'tooltip'
          input_html_options['data-placement'] ||= tooltip_position
          input_html_options['data-trigger'] ||= 'focus'
          input_html_options['data-original-title'] ||= tooltip_text
          nil
        end
      end

      def tooltip_text
        tooltip = options[:tooltip]
        tooltip.is_a?(String) ? tooltip : tooltip.is_a?(Array) ? tooltip[1] : nil
      end

      def tooltip_position
        tooltip = options[:tooltip]
        tooltip.is_a?(Array) ? tooltip[0] : "right"
      end
    end
  end
end

SimpleForm::Inputs::Base.send(:include, SimpleForm::Components::Tooltips)

我在_form.html.erb：

中这样称呼它

<%= f.input :title, placeholder: "Enter Title", tooltip: ["bottom", "Must be as it appears in the BANK STATEMENT"] %>

这是我的post.js - 为简洁起见也被截断：

$(document).ready(function () {
    $('#count').click(counter);
    $('#post_body, #post_title').on('change keydown keypress keyup blur focus', counter);
        $('body').tooltip({ selector: "[data-toggle~='tooltip']"});
});

这是我application.js的最重要部分：

//= require jquery
//= require jquery_ujs
//= require jquery.turbolinks
//= require bootstrap
//= require bootstrap/dropdown
//= require bootstrap/modal
//= require bootstrap/tooltip
//= require turbolinks
//= require_tree .

您使用的simple_form初始值设定代码用于bootstrap2，对于您可能想要使用的bootstrap3：

Tooltip组件不适用于Simple Form和Bootstrap
