A few days ago I posted a question :

How to show up an outputPanel with slide effect when there is focus on specific input box?

I got the solution to the above problem but another problem appeared before me. Each time the focus returned 开发者_运维知识库back to inputTextArea from some other element, the effect is again shown on the already visible outputPanel, which doesnt look very nice.

Thus I want to show up the effect only when the outputPanel was hidden & not everytime the focus returned to theinputTextArea. Is there any way, I can set this condition for the effect to be shown?

I don't know about Primefaces, but in jQuery you can do

if (!$("element").is(":visible")) 
{
//do something if element is not visibile
}

or

if ($("element").not(":visible")) 
{
//do something if element is not visibile
}
