javascript - 使用 jQuery 连续向左滑动动画

标签 javascript jquery asp.net jquery-animate

美好的一天，

我一直在尝试在此处和各种 Google 搜索中找到的各种方法(但没有成功)。我正在尝试重新创建在此 Microsoft Page 上找到的“Top Products Viewer”功能(看看位于页面顶部的旋转器正下方)。我在 CSS 和布局方面做得很好。但是，我在使动画正常工作时遇到了严重问题。

我希望幻灯片始终向左移动。

感谢任何帮助。我挖空了 animateLeftOnly 函数，因为我正在寻找一个新的选择。

更新:
下面的帮助非常有用。但范围的变化让我走上了不同的道路。以下是完整的最终工作版本:

                next.toggleClass(self.CSSCLASS_CURRENT);
                previous.toggleClass(self.CSSCLASS_CURRENT);

                self.current = next;
                self.previous = previous;

                if (self.categories.length <= 3)
                    return;

                // TODO: check if animation even needs to happen

                self.move();
            };
            this.move = function () {
                self.animateLeftOnly();
            };

            this.animateLeftOnly = function () {
               // Any help here is appreciated.
            };

            self.initialize();
        };

        return publicInstances;
    })(jQuery);

    var instance = undefined;

    $(document).ready(function () {

        instance = new slideScroll.controller('myControl');
    });
</script>

HTML 看起来像:

   <div id="myControl" class="slideScroll-horizontal">
        <div class="header">
            <h3>
                Top Products
            </h3>
        </div>
        <div class="content-categories">
            <div class="current">
                <h4>
                    <a>Most Popular</a>
                </h4>
            </div>
            <div>

            </div>
            <div>

            </div>
            <div class="last">
                <h4>
                    <a>Bada-Bing!</a>
                </h4>
            </div>
        </div>
        <div class="content-listing">
            <div data-index="0" class="html-template">

            </div>
            <div data-index="1" class="html-template">

            </div>
            <div data-index="2" class="html-template">

            <div data-index="3" class="html-template">
                four
            </div>
            <div data-index="4" class="html-template">
                five
            </div>
            <div data-index="5" class="html-template">
                six
            </div>
            <div data-index="6" class="html-template">
                seven
            </div>
            <div data-index="7" class="html-template">
                eight
            </div>
        </div>
    </div>

以前(可悲的)尝试看起来像:

this.animateLeftOnly = function () {

                var categoryIndex = self.current.index();
                var targetSlide = $("[data-index=" + categoryIndex + "]", self.list);
                var targetSlideIndex = targetSlide.index();

                var currentSlide = undefined;
                for (var i = 0; i < targetSlideIndex; i++) {

                    currentSlide = $('div.content-listing div:first');
                    currentSlide.animate({ width: 'hide' }, function () {

                        $(this).insertAfter('div.content-listing div:last', self.listItems);
                        $(this).removeAttr('style');
                    });
                }
                };

最佳答案

我被叫去开会，所以我不能完全回答，但你想做的很简单。 你想克隆第一个 child ，追加到最后，向左滑动，删除第一个 child 。这形成了一个无限循环。我做了很多次。

这里有一些东西可以让你开始......

<div class="content-categories">
    <div id="slider">
        <div class="current">
            <h4>
                <a>Most Popular</a>
            </h4>
        </div>
        <div>
            <h4>
                <a>Another</a>
            </h4>
        </div>
        <div>
            <h4>
                <a>last one</a>
            </h4>
        </div>
    </div>
</div>

你的 css 应该是这样的

.content-categories{
    width:300px;
    height:300px;
    position:relative;
    overflow:hidden;
}
.content-categories div{
    float:left;
    width:300px;
    height:300px;
}
#slider{
    width:900px;
    position:absolute;
    left:0;
}

然后是您的点击操作(假设您有一个图像或箭头或带有名为 left 的 id 的东西)

$('#left').click(function(){
    $('#slider').animate({left: '-300px'}, 1000, function(){
        $('#slider:first-child').clone().appendTo('#slider');
        $('#slider:first-child').remove();
        $('#slider').css('left', '0px');
    });
});

所以你克隆了第一个 child ，把它扔到 slider 容器的末尾，然后删除克隆的元素并将左边的位置返回到零。它应该是无缝的......现在就得运行。希望对你有帮助
