Removing and adding element in jquery not working as expected

I'm adding a sticky menu. The way I'm doing it is removing one and showing the other when scroll. It looked fine at first but then I realize that it is swapping the elements but not the content inside of them. Pay attention to the titles, "This is my red menu".

<div class="nav-one">
<div class="nav-two">


$(function() {
$(window).scroll(function() {
if ($(this).scrollTop() >= 1) {
} else {

What am I doing wrong? If you think it can be done differently, please let me know. This is my jsfiddle.


All your code is doing is switching around classes on the nav-* elements. It doesn't change the text, nor the visible element at all. From your description of what you want to have happen you should instead be hiding/showing the relevant .nav-* element based on the current scrollTop of the window, which you can achieve using toggle(), like this:

$(window).scroll(function() {
    $('.nav-one').toggle($(this).scrollTop() == 0);
    $('.nav-two').toggle($(this).scrollTop() >= 1);
.nav-two {
    /* other styling rules here... */
    display: none;

Working example

Note that I moved the hiding of the .nav-two element to the CSS to avoid a FOUC.
