长尾播放器 + 任何滑块 + 事件监听器

Question

我已经使用图像和视频内容（视频使用 longtail flv 播放器 - 许可版本 5）实现了 AnythingSlider (http://css-tricks.com/anythingslider-jquery-plugin/)。

问题：当用户播放视频时，幻灯片不知道发生了这种情况，因此幻灯片在视频运行时不断循环播放。所以您让幻灯片在运行 - 并且用户可以听到音频但视频已循环关闭。

• 更新 - 这是一个查看最新情况的链接：http://silverberry.org/beta/slider-longtail/

我正在尝试找出一个事件侦听器，当 LONGTAIL 播放器处于 PLAYING 状态时，它会查看并通知 AnySlider 它需要停止。

这是我到目前为止所得到的……视频播放器事件侦听器正在工作（现在我会弹出警报，以便我可以确定正在听到事件）。播放器初始化时会弹出警报..当我们按下视频上的播放按钮时会弹出警报...当视频停止播放时会弹出警报。 但是......我还没有制定出正确的语法来向anythingslider 发出信号以停止！

我以为会是这样：

$VUslider.startStop(false);

下面是我到目前为止的代码......从初始化滑块的代码开始。

    function formatText(index, panel) {
  return index + "";
  }
$(function () {
 $('.VUslider').VUslider({
 autoPlay: true,
    delay: 7000,
    startStopped: false,
    animationTime: 200,
    hashTags: true,
    buildNavigation: false,
    pauseOnHover: true,
    navigationFormatter: formatText
    });
});

var player = null;
function playerReadyCallback(obj)  {
 player = document.getElementsByName(obj.id)[0];
    alert('the videoplayer '+obj['id']+' has been instantiated');
    player.addModelListener('STATE',     'stateMonitor');
}
function stateMonitor(obj) {
   currentState = obj['newstate'];
 if(currentState == 'PLAYING') {
   alert ('the videoplayer '+obj['id']+'  is playing now!');
   $VUslider.startStop(false);  // Trigger slideshow stop   
    }
 if(obj.newstate == 'COMPLETED') {
   alert ('the videoplayer '+obj['id']+'  has stopped playing now!');
   $VUslider.startStop(true);  // Trigger slideshow start   
    }
}

供参考...这是任何滑块代码：

(function($){

    $.VUslider = function(el, options){
        // To avoid scope issues, use 'base' instead of 'this'
        // to reference this class from internal events and functions.
        var base = this;

        // Access to jQuery and DOM versions of element
        base.$el = $(el);
        base.el = el; 

        // Set up a few defaults
        base.currentPage = 1;
        base.timer = null;
        base.playing = false;

        // Add a reverse reference to the DOM object
        base.$el.data("AnythingSlider", base);

        base.init = function(){
            base.options = $.extend({},$.VUslider.defaults, options);

            // Cache existing DOM elements for later 
            base.$wrapper = base.$el.find('> div').css('overflow', 'hidden');

            base.$items.filter(':last' ).after(base.$items.filter(':first').clone().addClass('cloned'));

Answer 1

您是否将 $VUslider 设置为等于 $('.VUslider').VUslider({ . . }); ?

在您的示例代码中，您不是。

你应该这样做：

$VUslider = $('.VUslider').VUslider({
    autoPlay: true,
    delay: 7000,
    startStopped: false,
    animationTime: 200,
    hashTags: true,
    buildNavigation: false,
    pauseOnHover: true,
    navigationFormatter: formatText
});

Answer 2

这有点像在黑暗中刺伤，所以我将尝试解释一下我的推理。

在您已经创建 VUslider 位后，尝试执行此操作以启动/停止滑块：

$('.VUslider').VUslider.startStop(false);

// this will toggle between starting and stopping but doesn't give control
// to call start or stop specifically.
$('#start-stop').click();

当您调用 $('.VUslider').VUslider({...}) 时，它不会返回任何内容，因此此时 VUslider 没有句柄（$.each(..) 没有返回任何东西）。这有望让您获得对脚本和 startStop 函数的引用。
