How might you test if an HTML element is visible or hidden in the DOM?

Is it possible to toggle the visibility of a HTML element?

You can use the hidden selector:

// Matches all elements that are hidden
$('element:hidden')

And the visible selector:

// Matches all elements that are visible
$('element:visible')

Often when checking if something is visible or not, jQuery chaining makes this simple.

So if you have a selector and you need to play out some activity on it only if is visible or hidden, you can utilize filter(":visible") or filter(":hidden") trailed by chaining it with the action you want to make.

if statement example:

if ($('#btnUpdate').is(":visible"))
{
     $('#btnUpdate').animate({ width: "toggle" });   // Hide button
}

You can do it all in one line:

$('#btnUpdate').filter(":visible").animate({ width: "toggle" });
