当我将鼠标悬停在jQuery幻灯片中的图像上时,如何添加暂停效果?
$(document).ready(function () {
slideShow();
});
function slideShow() {
var showing = $('#slideshow .show');
var next = showing.next().length ? showing.next() : showing.parent().children(':first');
var timer;
showing.fadeOut(500, function () {
next.fadeIn(200).addClass('show');
}).removeClass('show');
setTimeout(slideShow, 3000);
}

var hovering = false; //default is not hovering
$("#slideshow").hover(function () { //*replace body with your element
hovering = true; //when hovered, hovering is true
}, function () {
hovering = false; //when un-hovered, hovering is false
slideShow(); //start the process again
});
function slideShow() {
if(!hovering) { //if not hovering, proceed
/* Your code here*/
nextSlide();
setTimeout(slideShow, 1000);
}
}
function nextSlide(){
var showing = $('#slideshow .show');
var next = showing.next().length ? showing.next() : showing.parent().children(':first');
var timer;
showing.fadeOut(500, function () {
next.fadeIn(200).addClass('show');
}).removeClass('show');
}

使用 .delay()
这将有所帮助。
说明:设置计时器以延迟队列中后续项目的执行。

我认为你需要两个函数... slideShow()和其他人说暂停幻灯片()...现在在mouseout事件和mouseenter调用中调用slideshow()pauseSlideShow()
你的代码应该是这样的
$(document).ready(function(){
$('.slider').mouseout( slideShow());
$('.slider').mouseenter( pauseSlideShow());
});
function slideShow() {
var showing = $('#slideshow .show');
var next = showing.next().length ? showing.next() : showing.parent().children(':first');
var timer;
showing.fadeOut(500, function() { next.fadeIn(200).addClass('show'); }).removeClass('show');
timeOut = setTimeout(slideShow, 3000);
}
function PauseSlideShow() {
window.clearTimeout(timeOut);
}
尝试

使用Derek的答案,悬停的替代方法是使用mouseenter
和mouseleave
。
参见工作幻灯片Jsfiddle: 演示: http://jsfiddle.net/highwayoflife/6kDG7/
var hovering = false;
var slideshow = $("#slideshow");
slideshow.mouseenter(function() {
hovering = true;
}).mouseleave(function() {
hovering = false;
slideShow();
});
function slideShow() {
if (!hovering) {
# Some browsers don't interpret "display:block" as being visible
# If no images are deemed visible, choose the first...
var currentImg = (slideshow.children("img:visible").length) ? slideshow.children("img:visible") : slideshow.children("img:first");
var nextImg = (currentImg.next().length) ? currentImg.next() : slideshow.children("img:first");
currentImg.fadeOut(500, function() {
nextImg.fadeIn(500, function() {
setTimeout(slideShow, 2000);
});
});
}
}
$(document).ready(function() {
slideShow();
});
