JQuery: Check whether an Element is Hidden from the user

Question

How to check whether a particular element is hidden from the user? In my code, under certain conditions, this code will be called:

$("#VersionSelectField").hide('fast'); 

So I have to make sure that if $("#VersionSelectField") is hidden, then I would not have to validate the value inside it when I submit the form ( I use JQuery Validate library for this purpose).

Any ideas?

Answer 1

$("#VersionSelectField").is(':hidden'); 

Answer 2

This works for me:

$("#VersionSelectField").css("display") == "none";
