我有一个悬停功能，可以在悬停在某些链接上时显示文本，而且效果很好。但是，仅当正文没有 user-is-touching 类时，我才尝试执行此函数。这有可能吗？如果可以，我该怎么做？
$(".o-c").hover(function() {
$('.home-o-c').show();
$('.home-i-t').hide();
}, function() {
$('.home-o-c').hide();
$('.home-i-t').show();
});
$(".c-f").hover(function() {
$('.home-c-f').show();
$('.home-i-t').hide();
}, function() {
$('.home-c-f').hide();
$('.home-i-t').show();
});
$(".i-c").hover(function() {
$('.home-i-c').show();
$('.home-i-t').hide();
}, function() {
$('.home-i-c').hide();
$('.home-i-t').show();
});
$(".c-u").hover(function() {
$('.home-c-u').show();
$('.home-i-t').hide();
}, function() {
$('.home-c-u').hide();
$('.home-i-t').show();
});
window.addEventListener('touchstart', function onFirstTouch() {
// we could use a class
document.body.classList.add('user-is-touching');
// or set some global variable
window.USER_IS_TOUCHING = true;
// or set your app's state however you normally would
// we only need to know once that a human touched the screen, so we can stop listening now
window.removeEventListener('touchstart', onFirstTouch, false);
}, false);
$(".o-c").click(function() {
if ($('body').hasClass('user-is-touching')) {
$('.home-o-c').show();
} else {
$('html, body').animate({
scrollTop: $(".our-company").offset().top
}, 2000);
}
});
$(".c-f").click(function() {
if ($('body').hasClass('user-is-touching')) {
$('.home-c-f').show();
$('.home-o-c').hide();
$('.home-i-c').hide();
$('.home-c-u').hide();
$('.home-i-t').hide();
} else {
$('html, body').animate({
scrollTop: $(".cf2").offset().top
}, 2000);
}

您可以在将 user-is-touching 类添加到 body 时取消绑定(bind)事件。
例子
$(".c-f").unbind('mouseenter').unbind('mouseleave')
或
$(".c-f").off('mouseenter').off('mouseleave')
更新
引用这个片段
// Replace this event listener with your hover listeners
window.addEventListener('touchstart', function onFirstTouch() {
// we could use a class
document.body.classList.add('user-is-touching');
// or set some global variable
window.USER_IS_TOUCHING = true;
// or set your app's state however you normally would
// Remove mouse-related events here
$(".o-c, .c-f, .i-c, .c-u").unbind('mouseenter').unbind('mouseleave')
// we only need to know once that a human touched the screen, so we can stop listening now
window.removeEventListener('touchstart', onFirstTouch, false);
}, false);
您需要更新您的 html 代码以在下面有 data-attr 属性更新代码
<li class="pivot-nav-item"><a data-attr="o-c" class="o-c default-underline" href="#"
data-toggle="my-scrollspy-2">O C</a></li>
<li class="pivot-nav-item"><a data-attr="c-f" class="c-f" href="#" data-toggle="my-scrollspy-2">C F</a></li>
<li class="pivot-nav-item"><a data-attr="i-c" class="i-c" href="#" data-toggle="my-scrollspy-2">I C</a></li>
<li class="pivot-nav-item" data-toggle="my-scrollspy-2"><a data-attr="c-u" class="c-u" href="#">C U</a></li>
