在发生某些事件后,如何重置jCarouselLite轮播上的自动滚动间隔,以便您可以查看整个间隔内的内容,而不管您单击下一步或上一步时的计时器时间有多长?现在,如果我在9秒后单击“下一步”或“上一步”,它将在1秒后再次滚动。
在jCarouselLite source code中,第274-277行是使用setInterval实现自动滚动的地方。我知道如果您有setInterval返回的ID,就可以使用clearInterval,但是除了修改源代码之外,我不能使用它,我不想这样做。
有什么想法吗?谢谢!

jCarouselLite本身没有提供任何简单的方法来停止自动滚动,这是一个比做你想做的事情更容易的问题(?我理解对了吗:你只是想在点击时暂时停止自动滚动,然后继续)
Hacky +潜在的buggy方式来完全停止自动滚动
var x; //hold interval id
$(function() {
var y = window.setInterval; //backup original setInterval function
//overwrite with new function which stores the id for us
window.setInterval = function() {
x = y(arguments[0], arguments[1]);
return x;
};
//now construct carousel
$(".anyClass").jCarouselLite({
btnNext: ".next",
btnPrev: ".prev",
auto: 500
});
//now restore original setInterval function
//as we only needed the custom one for the carousel to capture the hidden
//internal call to setInterval
window.setInterval = y;
});
$("#stopAutoScrollButton").click(function() {
clearInterval(x);
});真正的解决方案
因为我们不能让jCarouselLite自己来做这件事,所以我们自己模拟auto行为。
$(function() {
var autoTime = 5000; //5s
$(".anyClass").jCarouselLite({
btnNext: ".next",
btnPrev: ".prev"
});
//simulate autoscroll by simulating "click" on next link
var x = setInterval("$('.next').trigger('click');", autoTime);
//if stopAuto is clicked the autoscroll is suspended for autoTime
//no matter how far along the timer already was
$("#stopAuto").click(function() {
clearInterval(x);
x = setInterval("$('.next').trigger('click');", autoTime);
});

这是一个内置了鼠标悬停的版本。效果很好。http://github.com/cheald/jcarousel-lite

这些答案都不是我想要的,但这是当我搜索'jcarousellite reset timer‘时出现的,所以对于下一个寻找的人来说:
当您单击上一张/下一张幻灯片按钮时,
上的幻灯片
然后这是我放在一起的对我有用的东西:
(function($){$.fn.jCarouselLite=function(o){o=$.extend({btnPrev:null,btnNext:null,btnGo:null,mouseWheel:false,auto:null,speed:200,easing:null,vertical:false,circular:true,visible:3,start:0,scroll:1,beforeStart:null,afterEnd:null},o||{});return this.each(function(){var running=false,animCss=o.vertical?"top":"left",sizeCss=o.vertical?"height":"width";var div=$(this),a=$("#featuredlistings a.next"),ul=$("ul",div),tLi=$("li",ul),tl=tLi.size(),v=o.visible;if(o.circular){ul.prepend(tLi.slice(tl-v-1+1).clone()).append(tLi.slice(0,v).clone());o.start+=v;}var li=$("li",ul),itemLength=li.size(),curr=o.start;div.css("visibility","visible");li.css({overflow:"hidden",float:o.vertical?"none":"left"});ul.css({margin:"0",padding:"0",position:"relative","list-style-type":"none","z-index":"1"});div.css({overflow:"hidden",position:"relative","z-index":"2",left:"0px"});var liSize=o.vertical?height(li):width(li);var ulSize=liSize*itemLength;var divSize=liSize*v;li.css({width:li.width(),height:li.height()});ul.css(sizeCss,ulSize+"px").css(animCss,-(curr*liSize));div.css(sizeCss,divSize+"px");if(o.btnPrev)$(o.btnPrev).click(function(){resetAuto(); return go(curr-o.scroll);});if(o.btnNext)$(o.btnNext).click(function(){resetAuto(); return go(curr+o.scroll);});if(o.btnGo)$.each(o.btnGo,function(i,val){$(val).click(function(){return go(o.circular?o.visible+i:i);});});if(o.mouseWheel&&div.mousewheel)div.mousewheel(function(e,d){return d>0?go(curr-o.scroll):go(curr+o.scroll);});if(o.auto){autoScroll=setInterval(function(){go(curr+o.scroll);},o.auto+o.speed);function resetAuto(){clearInterval(autoScroll);autoScroll=setInterval(function(){go(curr+o.scroll);},o.auto+o.speed);};div.hover(function(){clearInterval(autoScroll);},function(){autoScroll=setInterval(function(){go(curr+o.scroll);},o.auto+o.speed);});}function vis(){return li.slice(curr).slice(0,v);};function go(to){if(!running){if(o.beforeStart)o.beforeStart.call(this,vis());if(o.circular){if(to<=o.start-v-1){ul.css(animCss,-((itemLength-(v*2))*liSize)+"px");curr=to==o.start-v-1?itemLength-(v*2)-1:itemLength-(v*2)-o.scroll;}else if(to>=itemLength-v+1){ul.css(animCss,-((v)*liSize)+"px");curr=to==itemLength-v+1?v+1:v+o.scroll;}else curr=to;}else{if(to<0||to>itemLength-v)return;else curr=to;}running=true;ul.animate(animCss=="left"?{left:-(curr*liSize)}:{top:-(curr*liSize)},o.speed,o.easing,function(){if(o.afterEnd)o.afterEnd.call(this,vis());running=false;});if(!o.circular){$(o.btnPrev+","+o.btnNext).removeClass("disabled");$((curr-o.scroll<0&&o.btnPrev)||(curr+o.scroll>itemLength-v&&o.btnNext)||[]).addClass("disabled");}}return false;};});};function css(el,prop){return parseInt($.css(el[0],prop))||0;};function width(el){return el[0].offsetWidth+css(el,'marginLeft')+css(el,'marginRight');};function height(el){return el[0].offsetHeight+css(el,'marginTop')+css(el,'marginBottom');};})(jQuery);只需将其与您当前的jCarouselLite脚本交换并使用它即可。
