jquery - Rails DatePicker - 对象[对象对象]没有方法'datepicker'

Question

我正在尝试将 datepicker 添加到我的 rails 3.2.8 应用程序中。

由于它是 rails 3+，我没有向 application.html.erb 添加任何内容。

我的 application.js 如下：

// 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 bootstrap
//= require_tree .

$(function(){
    $("#transaction_deadline").datepicker();
});

在views/transactions/_form.html.erb

我有：

<div class="field">
    <%= f.label :deadline %><br />
    <%= f.text_field :deadline %>
  </div>

但是，datepicker 仍然不起作用并给出：

TypeError: Object [object Object] 没有方法'datepicker'

错误

如果你能帮助我，那就太好了。

谢谢，

根据这个Railscast，您应该在 application.js 和 application.css 中显式添加 datepicker 组件。

在 application.js 中：

//= require jquery.ui.datepicker

在 application.css 中：

*= require jquery.ui.datepicker
