双动画,.stop()不修复它

出于某种原因,我无法弄清楚如何在以下脚本中停止双动画:

<script type="text/javascript">
    $(document).ready(function() {
        var activeNews = "01";
        $(".newsNav.forward").click(function(event) {
            event.preventDefault();
            if (activeNews == 01) {
                $(".newsItem.01").stop(true, true).fadeOut(250, function() {
                    $(".newsItem.02").stop(true, true).fadeIn(250);
                });
                activeNews = 02;
            } else if (activeNews == 02) {
                $(".newsItem.02").stop(true, true).fadeOut(250, function() {
                    $(".newsItem.03").stop(true, true).fadeIn(250);
                });
                activeNews = 03;
            } else if (activeNews == 03) {
                $(".newsItem.03").stop(true, true).fadeOut(250, function() {
                    $(".newsItem.01").stop(true, true).fadeIn(250);
                });
                activeNews = 01;
            }
        });
    });
</script>

当你过快地点击.newsNav.forward时,会出现多个.newsItems,而不只是一个.stop();。正如你所看到的,我知道<div id="news"> <a class="newsNav back" href="#">&lt;</a> <a class="newsNav forward" href="#">&gt;</a> <h1>Latest News</h1> <div id="newsSlider"> <p class="newsItem 01 active">First News Item</p> <p class="newsItem 02">Second News Item</p> <p class="newsItem 03">Third News Item</p> </div><!--/#newsSlider--> <div style="clear:both;"></div> </div><!--/#news--> 应该解决这个问题,但我无法弄清楚它为什么不起作用。

HTML如果相关:

#contentWrapper #content #news #newsSlider p.newsItem {
        display: none;
    }

    #contentWrapper #content #news #newsSlider p.newsItem.active {
        display: block;
    }

相关的CSS:

{{1}}

您只是停止某些类的动画。实现全球化&#34;在动画中停止,您将必须清除动画队列中所有可能在JS函数中设置动画的元素。

这意味着要做一些事情:

$(document).ready(function() {
    var activeNews = "01";
    $(".newsNav.forward").click(function(event) {
        event.preventDefault();

        // Pre-emptively stops all animation
        $(".newsItem").stop(true, true);

        // Note the removal of the .stop() method before each animation
        if (activeNews == 01) {
            $(".newsItem.01").fadeOut(250, function() {
                $(".newsItem.02").fadeIn(250);
            });
            activeNews = 02;
        } else if (activeNews == 02) {
            $(".newsItem.02").fadeOut(250, function() {
                $(".newsItem.03").fadeIn(250);
            });
            activeNews = 03;
        } else if (activeNews == 03) {
            $(".newsItem.03").fadeOut(250, function() {
                $(".newsItem.01").fadeIn(250);
            });
            activeNews = 01;
        }
    });
});
