Question

I’ve got this JavaScript

$(window).load(function(){
var $menu = $("header");
var opacity = $menu.css("opacity");
var scrollStopped;

var fadeInCallback = function () {
    if (typeof scrollStopped != 'undefined') {
        clearInterval(scrollStopped);
    }

    scrollStopped = setTimeout(function () {
        $menu.animate({ opacity: 1 }, "slow");
    }, 1400);
}

$(window).scroll(function () {
    if (!$menu.is(":animated") && opacity == 1) {
        $menu.animate({ opacity: 0 }, "200", fadeInCallback);
    } else {
        fadeInCallback.call(this);
    }
  });
});

It worked fine in hiding the header on scroll, but adding some height: 100%; to the html, body and a ‘content div’ with overflow hidden on html and body and auto on the ‘content div’ this javascript no longer works.

Any idea why this javascript doesn’t work? And is there a fix or other way to do it so the header fades out when scrolling?

Thanks in advance

your script works for me.

however if you want to try another method try the below, based on yours but a little simplified:

$(document).ready(function(){
    headerFade();
});
function headerFade() {
    var $menu = $("header"),
        opacity = $menu.css("opacity"),
        scrollStopped,
        methods = {
            init: function(){               
                $(window).scroll(function () {
                    (!$menu.is(":animated") && opacity == 1) ? $menu.fadeOut(200, methods.fadeInCallback()) : methods.fadeInCallback();                 
                });             
            },
            fadeInCallback: function(){             
                clearInterval(scrollStopped);                               
                scrollStopped = setTimeout(function () {
                    $menu.fadeIn(600);
                }, 1400);
            }
        };  
    methods.init();
};
