// Checks for display:[none|block], ignores visible:[true|false]
$(element).is(":visible");

This solution would seem to encourage the confustion of visible=false and display:none; whereas Mote's solution clearly illistrates the coders intent to check the display:none; (via mention of hide and show which control display:none not visible=true)

That is correct, but :visible will also check if the parent elements are visible, as chiborg pointed out.

You have a point - I'll make it clear that the code checks only for the display property. Given that the the original question is for show() and hide(), and they set display, my answer is correct. By the way it does work with IE7, here's a test snippet - jsfiddle.net/MWZss ;

I actually found that the reverse logic words better: !$('selector').is(':hidden'); for some reason. Worth a try.

Here's a simple benchmark testing is() against regexp:jsperf.com/jquery-is-vs-regexp-for-css-visibility. Conclusion: if you're out for performance, use regexp over is() (since is() looks for all hidden nodes first before looking at the actual element).

:visible
  • They have a CSS display value of none.
  • They are form elements with type="hidden".
  • An ancestor element is hidden, so the element is not shown on the page.

Elements with visibility: hidden or opacity: 0 are considered to be visible, since they still consume space in the layout.

This is useful in some cases and useless in others, because if you want to check if the element is visible (display != none), ignoring the parents visibility, you will find that doing .css("display") == 'none' is not only faster, but will also return the visibility check correctly.

If you want to check visibility instead of display, you should use: .css("visibility") == "hidden".

Because :visible is a jQuery extension and not part of the CSS specification, queries using :visible cannot take advantage of the performance boost provided by the native DOM querySelectorAll() method. To achieve the best performance when using :visible to select elements, first select the elements using a pure CSS selector, then use .filter(":visible").

Also, if you are concerned about performance, you should check Now you see me show/hide performance (2010-05-04). And use other methods to show and hide elements.

None of these answers address what I understand to be the question, which is what I was searching for, "How do I handle items that have visibility: hidden?". Neither :visible nor :hidden will handle this, as they are both looking for display per the documentation. As far as I could determine, there is no selector to handle CSS visibility. Here is how I resolved it (standard jQuery selectors, there may be a more condensed syntax):

$(".item").each(function() {
    if ($(this).css("visibility") == "hidden") {
        // handle non visible state
    } else {
        // handle visible state
    }
});

How you would test if an element has been hidden or shown using jQuery?
display
visibility: hidden
opacity: 0
:visible

you need to traverse up the DOM to check the node's parents, or else ,this is useless.

this won't work if you hide element with .hide().

You can use the hidden selector:

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

just be careful, there are some good performance related tips in this presentation: addyosmani.com/jqprovenperformance

On pages 21 to 28 it shows how slow :hidden or :visible is compared to other selectors. Thanks for pointing this.

When you're dealing with a couple of elements and very little is going on - i.e. THE ABSURDLY VAST MAJORITY OF CASES - the time issue is a ridiculously minor concern. Oh, noes! It took 42 ms instead of 19 ms!!!

I am toggling the element mamually using this selector. $('element:hidden') is always true for me!

@cwingrav You might want to re-read the documentation, :hidden applies to all elements. Form elements with type="hidden" is just one case that can trigger :hidden. Elements with no height and width, elements with display: none, and elements with hidden ancestors will also qualify as :hidden.

Often when checking if something is visible or not, you are going to go right ahead immediately and do something else with it. jQuery chaining makes this easy.

So if you have a selector and you want to perform some action on it only if is visible or hidden, you can use filter(":visible") or filter(":hidden") followed by chaining it with the action you want to take.

So instead of an if statement, like this:

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

You can do it all in one line:

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

No reason to extract the DOM node in the snippet used in the example, and then have to look it back up again. Better to just do: var $button = $('#btnUpdate'); And then in the If expressions just use $button instead of $(button). Has the advantage of caching the jQuery object.

Functions don't work with the visibility attribute.

This only checks for the display property of a single element. The :visible attribute checks also the visibility of the parent elements.

This is the only solution that worked for me when testing with IE 8.

This is not the solution to my problem but the method helped me identify a fix for checking against a property to my problem.

@chiborg Yes, but sometimes that's what you want and I had to learn the hard way how "clever" jQuery was...

This does answer the question, being the question is about a single element and by using the hide(), show() and toggle() functions, however, as most have already said, we should use the :visible and :hidden pseudo-classes.
