Apart from UI "flair", what do you use jQuery for? [closed]

Question

From an ASP.NET MVC perspective, what do you use jQuery for?

Apart from UI "flair" - things like fading colours and pretty animations.

Things I can immediately think of include pop-up calendars and modal popup dialogs, but there must be more...

Edit

I am interested in jQuery uses for things that ASP.NET MVC does not do out of the box, or things that jQuery makes easier/simpler.

Answer 1

Some of the things I use jQuery for are:

• simplified AJAX
• client-side validation
• forms that have application like behavior (ex changing the visible form elements based on a dropdown)
• interactive and dynamic menus
• client-side sorting
• dynamic textareas that grow as you type
• drag'n'drop
• integrating with a flash based multi-file uploader
