jquery, how to know div is hidden?

Question

I have code that uses jquery.slideup and jquery.slidedown

How can i know that div is hidden?

Answer 1

To see if an element is visible or not, you can use the visible selector with the is function:

$("#idElement").is(":visible") // true or false 

But sounds to me like you want to toggle the slide effect, for that you can use the slideToggle function.

Answer 2

$('#id').is(':hidden');    //true if is hidden $('#id').is(':visible');   //true if is visible 

But you may want to use slideToggle for your needs.
