Ruby on Rails Javascript在开发/生产中有所不同

Question

我对gem'jquery-datepicker'有问题。 我在application.js中的代码如下所示：

    //= require highcharts/highcharts.js
    //= require highcharts/highcharts-more.js
    //= require highcharts/highstock.js
    //= require highcharts/modules/exporting.js
    //= require jquery
    //= require jquery_ujs
    //= require jquery.ui.datepicker
    //= require_tree .
    //= require_self
    $(function() {
      $( ".datepicker_von" ).datepicker({·
        dateFormat: "dd.mm.yy",
        minDate: (new Date(2014,2,5)),  
        maxDate: 0,
        showAnim: "slideDown",
        changeMonth: true,
        changeYear: true,
        showOtherMonths: true,·
        selectOtherMonths: true,
      });                      
      $( ".datepicker_bis" ).datepicker({·
        dateFormat: "dd.mm.yy",
        minDate: (new Date(2014,2,5)),  
        maxDate: 0,            
        showAnim: "slideDown", 
        changeMonth: true,     
        changeYear: true,      
        showOtherMonths: true,·
        selectOtherMonths: true,
      });                      
    })

在开发环境中，日期选择器也会出现，但在生产环境中不会。 现在，当我将application.js更改为// = require_self时：

    //= require_self
    //= require highcharts/highcharts.js
    //= require highcharts/highcharts-more.js
    //= require highcharts/highstock.js
    //= require highcharts/modules/exporting.js
    //= require jquery
    //= require jquery_ujs
    //= require jquery.ui.datepicker
    //= require_tree .

它在生产环境中有效，但在开发环境中无效。 我感到绝望，需要帮助。

在此先感谢您，我的英语不好。

问候！

首先，将（ jquery和jqery_ujs ）移到清单文件的顶部

并添加document ready js datetimepicker

$( document ).ready(function() {
  $( ".datepicker_von" ).datepicker({·
        dateFormat: "dd.mm.yy",
        minDate: (new Date(2014,2,5)),  
        maxDate: 0,
        showAnim: "slideDown",
        changeMonth: true,
        changeYear: true,
        showOtherMonths: true,·
        selectOtherMonths: true,
      });
});
