我有一个弹出窗口，我打算让它的功能是使用交互式日历打开，该日历允许用户使用jquery datepicker输入开始日期和结束日期。但是当前在页面加载中，我必须打开和关闭弹出窗口两次，然后弹出窗口才能按预期运行，我想知道为什么会发生这种情况/如何解决？这是代码

** @BnB值是**
require 'pg'
class BnBControl
attr_accessor :connection
def self.all
@connection = PG.connect(dbname: 'bnb')
listings = @connection.exec("SELECT * FROM properties")
end
------
class BnB < Sinatra::Base
enable :sessions
get '/' do
#if session[:user]
@BnB = BnBControl.all
erb :index_logged_in
# else
# erb :index
# end
end

您使用document.ready和$(function()相同，不需要多次使用。另外，请在弹出单击事件处理程序之前在$(document).ready中调用datepicker函数，该函数应该对您有用。
尝试以下
$(document).ready(function() {
$( "#datepicker" ).datepicker();
$( "#datepicker2" ).datepicker();
$("#OpenDialog").click(function () {
$("#dialog").dialog({modal: true, height: 500, width: 700 });
});
});
