我正try 在我的本地计算机上重新创建这navbar.我已经正确加载了相关的html/css/js，包括jQuery，唯一的问题是当我将鼠标悬停在每个元素上时，元素背景不会更改为蓝色.
我try 重新安排头部部分中js/css的顺序，但没有任何变化.
下面是一个可重复使用的示例:
class StickyNavigation {
constructor() {
this.currentId = null;
this.currentTab = null;
this.tabContainerHeight = 70;
let self = this;
$('.et-hero-tab').click(function() {
self.onTabClick(event, $(this));
});
$(window).scroll(() => {
this.onScroll();
});
$(window).resize(() => {
this.onResize();
});
}
onTabClick(event, element) {
event.preventDefault();
let scrollTop = $(element.attr('href')).offset().top - this.tabContainerHeight + 1;
$('html, body').animate({
scrollTop: scrollTop
}, 600);
}
onScroll() {
this.checkTabContainerPosition();
this.findCurrentTabSelector();
}
onResize() {
if (this.currentId) {
this.setSliderCss();
}
}
checkTabContainerPosition() {
let offset = $('.et-hero-tabs').offset().top + $('.et-hero-tabs').height() - this.tabContainerHeight;
if ($(window).scrollTop() > offset) {
$('.et-hero-tabs-container').addClass('et-hero-tabs-container--top');
} else {
$('.et-hero-tabs-container').removeClass('et-hero-tabs-container--top');
}
}
findCurrentTabSelector(element) {
let newCurrentId;
let newCurrentTab;
let self = this;
$('.et-hero-tab').each(function() {
let id = $(this).attr('href');
let offsetTop = $(id).offset().top - self.tabContainerHeight;
let offsetBottom = $(id).offset().top + $(id).height() - self.tabContainerHeight;
if ($(window).scrollTop() > offsetTop && $(window).scrollTop() < offsetBottom) {
newCurrentId = id;
newCurrentTab = $(this);
}
});
if (this.currentId != newCurrentId || this.currentId === null) {
this.currentId = newCurrentId;
this.currentTab = newCurrentTab;
this.setSliderCss();
}
}
setSliderCss() {
let width = 0;
let left = 0;
if (this.currentTab) {
width = this.currentTab.css('width');
left = this.currentTab.offset().left;
}
$('.et-hero-tab-slider').css('width', width);
$('.et-hero-tab-slider').css('left', left);
}
}
