[英]Fixed Nav Bar, Broken Javascript
我目前正在網站上工作,並且正在嘗試使滾動/固定導航欄正常工作。 我不打算繼續學習本教程 ,但是我無法像他的預覽中那樣淡入/淡出。 我已經嘗試了所有我能想到的一切,只是將計算機扔在牆上。 我對Java語言的了解不多,所以這只會增加無奈感。
我在此處發布了代碼預覽,並在下面列出了代碼的javascript部分。 任何和所有幫助將不勝感激。
$(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);
}
});
});
