我一直致力于自定义this bootstrap responsive tabs示例。当用户将鼠标悬停在左/右箭头图标上时，我想要的是像滑块一样循环选项卡。除此之外，如果用户一直悬停在左/右箭头图标上，我还希望滑块保持循环。我为此写了以下代码：
(function() {
function changeTab() {
console.log("mouseenterd on ", $(this));
if ($(this).closest("li").hasClass("next") && !$(this).closest("li").hasClass("hovered")) {
$(this).closest(".nav-tabs").children("li").removeClass("hovered");
$(this).tab('show');
} else if ($(this).closest("li").hasClass("prev") && !$(this).closest("li").hasClass("hovered")) {
$(this).closest(".nav-tabs").children("li").removeClass("hovered");
$(this).tab('show');
}
}
function outOfHover() {
console.log("mouseleave on ", $(this));
if ($(this).closest("li").hasClass("hovered")) {
$(this).closest(".nav-tabs").children("li").removeClass("hovered");
}
}
$('[data-toggle="tab"], [data-toggle="pill"]').on('mouseleave', outOfHover); //removes class hovered
$('[data-toggle="tab"], [data-toggle="pill"]').on('mouseenter', changeTab); //runs bootstrap tabs like slider
var triggerClickTab;
var triggerClickCarousel;
function triggerClick(that) {
$(that).tab('show');
console.log("show triggered " + " ", $(that));
}
$('[data-toggle="tab"], [data-toggle="pill"]').on('mouseenter', function() {
var that = this;
triggerClickTab = setInterval(triggerClick, 1650, that);
});
$('[data-toggle="tab"], [data-toggle="pill"]').on('mouseleave', function() {
clearInterval(triggerClickTab);
});
$("#myCarousel .carousel-control").on('mouseenter', function() {
if ($(this).hasClass("left")) {
$("#myCarousel").carousel('prev');
} else if ($(this).hasClass("right")) {
$("#myCarousel").carousel('next');
}
var that = this;
triggerClickCarousel = setInterval(triggerClick, 1650, that);
});
$("#myCarousel .carousel-control").on('click', function() {
clearInterval(triggerClickCarousel);
var that = this;
triggerClickCarousel = setInterval(triggerClick, 1650, that)
});
$("#myCarousel .carousel-control").on('mouseleave', function() {
clearInterval(triggerClickCarousel);
});
/* end if Condition for non-touch device finsihes here */
$(document).on('show.bs.tab', '.nav-tabs [data-toggle="pill"], .nav-tabs [data-toggle="tab"]', function(e) {
var $target = $(e.target);
var $tabs = $target.closest('.nav-tabs');
var $current = $target.closest('li');
var $parent = $current.closest('li.dropdown');
$current = $parent.length > 0 ? $parent : $current;
var $next = $current.next();
var $prev = $current.prev();
var updateDropdownMenu = function($el, position) {
$el
.find('.dropdown-menu')
.removeClass('pull-left pull-center pull-right')
.addClass('pull-' + position);
};
$tabs.find('>li').removeClass('hovered');
if ($current.hasClass("next")) {
$next.addClass('hovered');
} else if ($current.hasClass("prev")) {
$prev.addClass('hovered');
}
$tabs.find('>li').removeClass('next prev');
$prev.addClass('prev');
$next.addClass('next');
updateDropdownMenu($prev, 'left');
updateDropdownMenu($current, 'center');
updateDropdownMenu($next, 'right');
});

He lay on his armour-like back, and if he lifted his head a little he could see his brown belly, slightly domed and divided by arches into stiff sections.

由于媒体查询，代码在stackoverflow上无法正常工作。请尝试使用具有完全相同代码的filddle并正常工作：https://jsfiddle.net/hhtm1on3/ Plz缩小输出宽度，直到看到左/右箭头标签版本。
jsfiddle代码在firefox浏览器中正常工作，但在chrome浏览器中不正常。我在触发特定事件时在控制台中添加了注释。正如你在firefox mouseleave上看到的那样，在显示每个选项卡但不显示chrome时会继续触发。 mouseout事件也是如此。

如果光标不移动，Chrome已知不处理某些鼠标事件。与UI重绘优化有关。
一种解决方法可能是强制每个间隔回调一次UI重绘。有很多方法可以强制重绘，一种是重新绘制元素本身，例如：
