我正在尝试让 token 字段在我的应用程序上工作。

我完全按照这个视频:http://railscasts.com/episodes/258-token-fields

项目型号

class Project < ActiveRecord::Base
attr_accessible :edited_first_name, :edited_last_name, :first_name, :last_name, :business_div, :client, :customer_benifits, :edited_date, :end_date, :entry_date, :financials, :industry, :keywords, :lessons_learned, :project_name, :project_owner, :role, :start_date, :status, :summary, :tech , :technols, :technol_tokens


has_many :projecttechnols
has_many :technols, :through => :projecttechnols

attr_reader :technol_tokens

def technol_tokens=(ids)
self.technol_ids = ids.split(",")
end


accepts_nested_attributes_for(:technols)

技术 Controller :
def index
@technols = Technol.where("tech like ?", "%#{params[:q]}%")

respond_to do |format|
format.html # index.html.erb
format.json { render :json => @technols.map(&:attributes) }
end
end

布局/application.html.erb
<!DOCTYPE html>

<div id="user_nav">

<% end %>



<div class="back_button2">
<%= button_to "Back", projects_path , :class => "button", :method => "get" %>
</div>

应用程序.js 编辑:
$(function() {
$("#project_technol_tokens").tokenInput("/technols.json", {
crossDomain: false,
prePopulate: $("#project_technol_tokens").data("pre"),
theme: "facebook"
});
});



$(function() {
$("#project_start_date").datepicker({dateFormat: 'dd-mm-yy'});
});

$(function() {
$("#project_end_date").datepicker({dateFormat: 'dd-mm-yy'});
});



jQuery(function(){

jQuery('#start_date_A').datepicker({dateFormat: "dd-mm-yy"});
});

jQuery(function(){

jQuery('#start_date_B').datepicker({dateFormat: "dd-mm-yy"});
});

在我的新页面上,我有一个可以工作的 jquery datepicker 文本框。我不明白为什么同一页面上的 token 字段不起作用。

我已经按照视频大约 3 次来确保它仍然无法正常工作。唯一的区别是我将我的 javascripts 和样式表放在 assets 文件夹中,在视频中它放在 public 文件夹中。任何人都可以帮忙吗?谢谢。

最佳答案

不是一个可能的错误。请尝试以下方法:

  • 检查您的 application.js 文件。您是否包含了 jquery.tokeninput.js 文件?
  • 确保application.js中jquery后需要token-input js文件
  • 检查以确保包含 CSS 文件
  • 在浏览器中,您是否在控制台中收到任何 js 错误?如果是这样,请修改问题。

  • 编辑

    另外,我刚刚注意到,在您的 new.html.erb 中,在 html 结束标记之后有一个 div !
    </BODY>
    </HTML>

    请删除/将它们放置在适当的位置。
