How to tell an element is visible with jQuery

To check if an element is visible
if( $('#foo').is(':visible') ) {
    // it's visible, do something
}
else {
    // it's not visible so do something else
}

To check if an element is hidden
if( $('#foo').is(':hidden') ) {
    // it's hidden, do something
}
else {
    // it's not hidden so do something else
}

How do you test to see if that element is currently hidden or visible on the screen?

Answer:

$(element).is(":visible") 

// Checks for display:[none|block], ignores visible:[true|false]
