我正在使用 Rails 3.2 版和 Ruby 1.9.3
我正在尝试在 form_tag 中创建一个 datepicker 字段。在我的 GemFile 中，我添加了 gem 'jquery-rails'、gem 'jquery-ui-rails' 和 gem 'jquery_datepicker'。在 Rails 控制台中，我使用了以下命令： rails generate jquery:install --ui
Application.js 看起来像这样：
// This is a manifest file that'll be compiled into application.js, which will include all the files
// listed below.
//
// Any JavaScript/Coffee file within this directory, lib/assets/javascripts, vendor/assets/javascripts,
// or vendor/assets/javascripts of plugins, if any, can be referenced here using a relative path.
//
// It's not advisable to add code directly here, but if you do, it'll appear at the bottom of the
// the compiled file.
//
// WARNING: THE FIRST BLANK LINE MARKS THE END OF WHAT'S TO BE PROCESSED, ANY BLANK LINE SHOULD
// GO AFTER THE REQUIRES BELOW.
//
//= require jquery
//= require jquery_ujs
//= require jquery_ui.all
//= require_tree .
$(function() {
$(".datepicker" ).datepicker({dateFormat: "yy/mm/dd"});
});
应用程序.css：
/*
* This is a manifest file that'll be compiled into application.css, which will include all the files
* listed below.
*
* Any CSS and SCSS file within this directory, lib/assets/stylesheets, vendor/assets/stylesheets,
* or vendor/assets/stylesheets of plugins, if any, can be referenced here using a relative path.
*
* You're free to add application-wide styles to this file and they'll appear at the top of the
* compiled file, but it's generally better to create a new file per style scope.
*
*= require_self
*= require_tree .
*= require_jquery.ui.all
*/
And in the view:
<%= form_tag url: {action: 'do_something'} do |f| %>
<%= text_field_tag :birth_date, '', :class => "datepicker" %>
<%= submit_tag "Do something man!"%>
<% end %>
form_tag 的 datepicker 函数的正确调用是什么？
Update1：在 chromium 浏览器中，调试 $(".datepicker") 返回 null .. 编辑了我的文件（感谢 Sagar.Patil）
FinalUpdate：我还没有找到关于这个问题的解决方案。尝试并成功使用 bootstrap-datepicker。
