我一直在努力定制这个bootstrap响应选项卡示例.我想要的是当用户将鼠标悬停在左/右箭头图标上时,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');
});

</div>由于媒体查询,代码在stackoverflow上无法正常工作.请尝试这个具有完全相同的代码并且工作正常的filddle:https://jsfiddle.net/hhtm1on3/ Plz缩小输出宽度,直到您看到左/右箭头选项卡的版本.
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.正如你所看到的那样,firefox mouseleave会在显示每个标签后继续触发,但不会显示铬.情况与此相同mouseout的事件.
题:
众所周知,如果光标不移动,则Chrome不会处理某些鼠标事件.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个UI重绘.有很多方法可以强制重绘,一个是重绘元素本身,例如:
function triggerClick(that) {
$(that).tab('show').hide().show(0); // force a repaint
console.log("show triggered " + " ", $(that));
}
