Javascript Datepicker ajax调用beforeShow;不起作用

Javascript Datepicker ajax调用beforeShow;不起作用,javascript,jquery,coffeescript,datepicker,Javascript,Jquery,Coffeescript,Datepicker,我有一个显示数据库中可用日期的页面。它工作得很好,但我必须刷新页面才能让它工作。如果我没有,datepicker类就像一个文本框。此外,我需要它在显示之前进行ajax调用 总之,我转到“/tasks/new”。页面加载正确。我在datepicker字段中单击,没有日历。控制台中没有错误。我刷新页面,它就工作了。我需要做什么?我最初的想法是需要等待页面加载,但这似乎不起作用(除非我做错了) 以下是相关代码: html tasks.js.coffee full_days =[] partial_

我有一个显示数据库中可用日期的页面。它工作得很好,但我必须刷新页面才能让它工作。如果我没有,datepicker类就像一个文本框。此外,我需要它在显示之前进行ajax调用

总之,我转到“/tasks/new”。页面加载正确。我在datepicker字段中单击,没有日历。控制台中没有错误。我刷新页面,它就工作了。我需要做什么?我最初的想法是需要等待页面加载,但这似乎不起作用(除非我做错了)

以下是相关代码:

我找到了解决问题的方法。这一切都是关于我何时调用函数以及何时放置初始值

beforeShow:->getDays
应该是
beforeShow:getDays
还是
beforeShow:->getDays()
?这帮助我解决了部分问题。谢谢
