javascript - Rails 3 个不同的自动完成字段

Question

我在页面上有 2 个不同的自动完成字段，每个字段都从数据库中的不同源填充。我的问题是，当我测试页面时，两种自动完成行为有时会在彼此的文本字段中切换。

我的 View 部分如下所示(我遵循 railscasts ):

<fieldset>
  <%= f.text_field :ability_title, {:class => 'autocomplete_field', data: { autocomplete_source: abilities_path } } %>
  <%= f.label :points %>: <%= f.text_field :points %>
  <%= f.hidden_field :_destroy %>
  <%= link_to "remove", '#', class: "remove_fields" %>
</fieldset>

<fieldset>
  <%= f.text_field :mission_title, {:class => 'autocomplete_field', data: {autocomplete_source: missions_path } } %>
  <%= f.hidden_field :_destroy %>
  <%= link_to "remove", '#', class: "remove_fields" %>
</fieldset>

我的 JavaScript:

jQuery ->
  $('fieldset').live 'click', ->
    $('.autocomplete_field').autocomplete
      source: $('.autocomplete_field').data('autocomplete-source')

和我的 Controller :

def index
  if params[:term].present?
    @abilities = Ability.search_titles(params[:term])
  else
    @abilities = Ability.all
  end

  respond_to do |format|
    format.html # index.html.erb
    format.json { render json: @abilities }
  end
end

def index
  if params[:term].present?
    @missions = Mission.search_titles(params[:term])
  else
    @missions = Mission.all
  end

  respond_to do |format|
    format.html # index.html.erb
    format.json { render json: @missions.map(&:title) }
  end
end

谢谢

我认为你只需要通过 id 来区分两个文本字段，例如:

<fieldset>
  <%= f.text_field :ability_title, {:id => 'autocomplete_field1', data: { autocomplete_source: abilities_path } } %>
  <%= f.label :points %>: <%= f.text_field :points %>
  <%= f.hidden_field :_destroy %>
  <%= link_to "remove", '#', class: "remove_fields" %>
</fieldset>

<fieldset>
  <%= f.text_field :mission_title, {:id => 'autocomplete_field2', data: {autocomplete_source: missions_path } } %>
  <%= f.hidden_field :_destroy %>
  <%= link_to "remove", '#', class: "remove_fields" %>
</fieldset>
My javascript:

jQuery ->
  $('fieldset').live 'click', ->

    $('#autocomplete_field1').autocomplete
      source: $('#autocomplete_field1').data('autocomplete-source')
    $('#autocomplete_field2').autocomplete
      source: $('#autocomplete_field2').data('autocomplete-source')

编辑: 更优雅的解决方案:

jQuery ->
  $('fieldset').live 'click', ->
    $('#autocomplete_field1, #autocomplete_field2').each (index, element) =>
      $(element).autocomplete
        source: $(element).data('autocomplete-source')
