What is the best calendar pop-up to populate a web form?

Question

I want to be able to make an HTTP call updating some select boxes after a date is selected. I would like to be in control of updating the textbox so I know when there has been a "true" change (in the event the same date was selected). Ideally, I would call a function to pop-up the calendar and be able to evaluate the date before populating the text box...so I can do my validation before making a server call.

Answer 1

JQuery's datepicker is an extremely flexible tool. With the ability to attach handlers prior to opening or after date selection, themes, range selection and a variety of other incredibly useful options, I've found that it meets all my needs.

The fact that I sit next to one of its maintainers here at work is also fairly useful...

Answer 2

I've been playing with the jquery datePicker script - you should be able to do everything you need to with this.

Answer 3

YUI and ExtJs both have very nice looking and flexible calendars.

Answer 4

If you ever end up considering a JavaScript library/toolkit, Dijit, a widget system which layers on top of Dojo, has a calendar (Dijit calendar test page). I found it relatively simple to implement.

//Disclaimer: I'm in the middle of a love-hate relationship w/ Dojo at the moment, as I am in the process of learning and using it better.

Answer 5

I don't like the MS ASP.NET ajax, but their datepicker is superb. Otherwise, jQuery datepicker.

Answer 6

Check out the ASP.NET AJAX Calendar Extender or Steve Orr's drop down Calendar control.

I'm using the JSCalendar from Dynarch for a project I'm currently working on. It is LGPL licensed and really flexible (easy to customize to your needs). It has lots of features and looks good, too.
