我使用粘性導航創建頁面,並且在標題圖像移開後它不會緊貼頂部(小於整頁大小)。它只在一張完整頁面圖像的大小通過後才粘住。導航欄內的文本在粘貼後也會移動。粘滯導航棒太遲
您可以查看這裏的代碼:https://jsfiddle.net/zinctan/7a436ojz/
這是我的javascript:
$(function() {
// when we scroll down the window, do this:
$(window).scroll(function(){
//Getting the scroll percentage
var windowHeight = $(window).height();
var scrollHeight = $(window).scrollTop();
var scrollPercentage = (scrollHeight/windowHeight);
console.log(scrollPercentage);
// if we have scrolled past 200, add the alternate class to nav bar
if(scrollPercentage > 1) {
$('.navHighlighter').addClass('scrolling');
} else {
$('.navHighlighter').removeClass('scrolling');
}
});
$('a[href*=#]:not([href=#])').click(function() {
if (location.pathname.replace(/^\//,'') == this.pathname.replace(/^\//,'') && location.hostname == this.hostname) {
var target = $(this.hash);
target = target.length ? target : $('[name=' + this.hash.slice(1) +']');
if (target.length) {
$('html,body').animate({
scrollTop: target.offset().top - 80
}, 1000);
return false;
}
}
}); // code courtesy of CSS-Tricks
// apply the class of nav-active to the current nav link
$('a').on('click', function(e) {
e.preventDefault();
$('li.nav-active').removeClass('nav-active');
$(this).parent('li').addClass('nav-active');
});
// get an array of 'href' of each a tag
var navLink = $('ul.navHighlighter a');
console.log(navLink);
var aArray = [];
for(var i = 0; i < navLink.length; i++) {
console.log(i);
var aChild = navLink[i];
var navArray = $(aChild).attr('href');
console.log(navArray);
aArray.push(navArray);
console.log(aArray);
var selector = aArray.join(" , ");
console.log(selector);
}
$(window).scroll(function(){
var scrollTop = $(window).scrollTop();
var tops = [];
$(selector).each(function(){
var top = $(this).position().top - 90;
if(scrollTop > top) {
var id = $(this).attr('id');
$('.nav-active').removeClass('nav-active');
$('a[href="#'+id+'"]').parent().addClass('nav-active');
}
tops.push(top);
});
});
});
任何幫助將是有用的!謝謝:)
