jQuery check if browser support position: fixed

Question

How do I check if browser supports position:fixed using jQuery. I assume I have to use $.support I think, but how?

Thank you for your time.

Answer 1

function fixedcheck () {
    var fixedDiv = $('
').css('position', 'fixed').appendTo('body');
    var pos1 = fixedDiv.offset().top;
    $(window).scrollTop($(window).scrollTop() + 1);
    var pos2 = fixedDiv.offset().top;
    fixedDiv.remove();
    return (pos1 != pos2)
}

/* Usage */
$(document).ready(function () {
    if (!fixedcheck()) alert('Your browser does not support fixed position!')
});
