jQuery轮播 - 当到达列表中的最后一项时禁用下一个/上一个链接

Question

我对jQuery非常陌生，我所做的只是我遵循了在这里完成的事情：

carousel using jQuery

但我只是想问一下，如果我想滑到最后一项，然后禁用指示已到达最后一项的链接，那么我们只需停止滑动该怎么办？请帮忙，我真的不需要无限幻灯片。

这是我的代码

$(function(){
    var carousel = $('.carousel ul');
    var carouselChild = carousel.find('li');
    var clickCount = 0;
    var canClick = true;

    itemWidth = carousel.find('li:first').width()+1; //Including margin

    //Set Carousel width so it won't wrap
    carousel.width(itemWidth*carouselChild.length);

    //Place the child elements to their original locations.
    refreshChildPosition();

    //Set the event handlers for buttons.
    $('.btnNext').click(function(){
        if(canClick){
            canClick = false;
            clickCount++;

            //Animate the slider to left as item width 
            carousel.stop(false, true).animate({
                left : '-='+itemWidth
            },300, function(){
                //Find the first item and append it as the last item.
                lastItem = carousel.find('li:first');
                lastItem.remove().appendTo(carousel);
                lastItem.css('left', ((carouselChild.length-1)*(itemWidth))+(clickCount*itemWidth));
                canClick = true;
            });
        }
    });

    $('.btnPrevious').click(function(){
        if(canClick){
            canClick = false;
            clickCount--;
            //Find the first item and append it as the last item.
            lastItem = carousel.find('li:last');
            lastItem.remove().prependTo(carousel);

            lastItem.css('left', itemWidth*clickCount);             
            //Animate the slider to right as item width 
            carousel.finish(true).animate({
                left: '+='+itemWidth
            },300, function(){
                canClick = true;
            });
        }
    });

    function refreshChildPosition(){
        carouselChild.each(function(){
            $(this).css('left', itemWidth*carouselChild.index($(this)));
        });
    }
});

您只需检查幻灯片窗口的第一个和最后一个li。

这对你有用：

$(function(){
    var carousel = $('.carousel ul');
    var carouselChild = carousel.find('li');
    var clickCount = 0;
    var canClick = true;

    itemWidth = carousel.find('li:first').width()+1; //Including margin

    //Set Carousel width so it won't wrap
    carousel.width(itemWidth*carouselChild.length);

    //Place the child elements to their original locations.
    refreshChildPosition();

    //Set the event handlers for buttons.
    $('.btnNext').click(function(e){        
        if($(".carousel").find("li:eq(6)").text()!=14) {
            if(canClick) {
                canClick = false;
                clickCount++;
                //Animate the slider to left as item width 
                carousel.stop(false, true).animate({
                    left : '-='+itemWidth
                },300, function(){
                    //Find the first item and append it as the last item.
                    lastItem = carousel.find('li:first');
                    lastItem.remove().appendTo(carousel);
                    lastItem.css('left', ((carouselChild.length-1)*(itemWidth))+(clickCount*itemWidth));
                    canClick = true;
                });
            }
        }
    });

    $('.btnPrevious').click(function(){
        if($(".carousel").find("li:eq(0)").text()!=1) {
            if(canClick){
                canClick = false;
                clickCount--;
                //Find the first item and append it as the last item.
                lastItem = carousel.find('li:last');
                lastItem.remove().prependTo(carousel);

                lastItem.css('left', itemWidth*clickCount);             
                //Animate the slider to right as item width 
                carousel.finish(true).animate({
                    left: '+='+itemWidth
                },300, function(){
                    canClick = true;
                });
            }
        }
    });

    function refreshChildPosition(){
        carouselChild.each(function(){
            $(this).css('left', itemWidth*carouselChild.index($(this)));
        });
    }
});
