我目前正在网站上工作,我试图让滚动/固定导航栏工作。我已离开this tutorial,但我不能像我的预览一样让我淡入淡出。我已经尝试过所有我能想到的东西,而不是将电脑扔在墙上。我不太了解Javascript,所以这只会让人感到沮丧。
我发布了代码here的预览版,并且我已经列出了以下代码的javascript部分。任何和所有的帮助将不胜感激。
$(document).ready(function(){
$('#navigation a, #fixedbar a').on('click', function(e) {
e.preventDefault();
});
$(window).on('scroll',function() {
var scrolltop = $(this).scrollTop();
if(scrolltop >= 110) {
$('#fixedbar').fadeIn(100);
}
else if(scrolltop <= 110) {
$('#fixedbar').fadeOut(100);
}
});
});
