我正在尝试在 Tealium 中配置 Vzaar 视频跟踪。关于如何进行的文档很少。

这是文档的链接

https://community.tealiumiq.com/t5/iQ-Tag-Management/Vzaar-Video-Tracking/ta-p/5934

这是上面链接中提到的文档提供的自定义 javascript 代码

var video_events = ["playState","progress","interaction"];  // Possible values are "playState", "progress" and/or "integration"
var milestone_percentages = ["10","20","30","40","90"];  // These must be rounded to the nearest 10
var player_element_id = "vzvd-1556961";
var player_type = "iframe"; // Possible values are "iframe" or "html"

var played = false;
var m1 = false;
var m2 = false;
var m3 = false;
var m4 = false;

// Call utag.link in Vzaar event listeners
window._tealium_VZ = {
  name : "Vzaar",
  init_tries : 0,
  eventsAdded : false,
  events : video_events,
  milestone_percentages : milestone_percentages,
  mediaEventHandler :  function (pEvent) {
    pos = _tealium_VZ.player_object.getTime();
    dur = _tealium_VZ.player_object.getTotalTime();
     if (pEvent=="mediaStarted" || pEvent=="started") {
      alert('I am here');
      played = true;
      utag.DB("**** video started ****");
      utag.link({event_type:"video",event_name:"play"})
      ////s.Media.open(video_name, video_duration, video_player);
      ////s.Media.play(video_name, 0);
      //s.Media.track(video_name);
    } else if(pEvent=="resume"){

    }else{
      var ms = pEvent.replace(/[^0-9]/g, "")
      for(var i=0;i<_tealium_VZ.milestone_percentages.length;i++){
         if(ms==_tealium_VZ.milestone_percentages[i]){
            var ms_num =(i+1);
            utag.link({event_type:"video",event_name:"milestone",video_milestone:"M:"+ms_num+":"+_tealium_VZ.milestone_percentages[i],video_position:pos,video_duration:dur})

    if(a=="iframe"){
        for(var i=0;i<video_events.length;i++){
            _tealium_VZ.player_object.addEventListener(_tealium_VZ.events[i],_tealium_VZ.mediaEventHandler);

            }
        }
    }else if(!_tealium_VZ.eventsAdded){
      // If Vzaar object is not defined we will increment the number of tries by 1
      _tealium_VZ.init_tries += 1;
      //Stop trying to connect to the Video Player if tried 100 times
      if(_tealium_VZ.init_tries>100){
        utag.DB("TEALIUM: Cannot connect to Vzaar Video");
        return;
      }
      // Calls init function repeatedly either 100 times or Vzaar Object is defined
      setTimeout(function(){_tealium_VZ.init()}, 100);
    }
  }
}

if(typeof _tealium_VZ.videoPlayer == "undefined"){
    _tealium_VZ.init();
}

我用我写的附加到 iframe url 的这段代码开始这个脚本，我还将自定义 javascript 代码扩展设置为预加载器函数

window.addEventListener('load', function(){
    var ifrm = document.getElementsByTagName('iframe')[0];
    ifrm.src += '&apiOn=true';
}, false);

当我在视频上按播放时，我仍然没有看到任何事件被触发。我需要对此脚本执行什么操作才能开始接收跟踪数据？我猜我需要在 Tealium 学习社区文档提供的脚本中删除一些评论块，但是，我正在尝试但仍然没有看到结果。任何帮助，将不胜感激！

您应该检查几件事，并且由于缺少处理订单上下文，我会假设，如果您已经考虑到这一点，我们深表歉意。

  1. 预加载器扩展

您在此处复制/粘贴扩展内容，但您是否考虑过需要指定 id 的第 3 行？

var player_element_id = "vzvd-1556961";

我只是提到，因为在您的自定义脚本中，您正在根据 TAG 类型获取元素

var ifrm = document.getElementsByTagName('iframe')[0];
  1. 在自定义脚本上，建议检查查询参数是否已经存在。
window.addEventListener('load', function(){
    var ifrm = document.getElementsByTagName('iframe')[0];
    if (ifrm.src.indexOf("apiOn=true") === -1) 
       if (ifrm.src.indexOf("?") === -1) 
          ifrm.src += '?apiOn=true';
       else
          ifrm.src += '&apiOn=true';   
}, false);
  1. 因为使用 Tealium 一切都是异步的，所以“预加载器”扩展总是有可能在 iframe 在 DOM 上准备好之前运行代码。因此，为了确保仅在文档准备好时才初始化扩展代码，我会将扩展对象初始化指令移动到自定义脚本的主体中。像这样的东西：
window.addEventListener('load', function(){
    var ifrm = document.getElementsByTagName('iframe')[0];
    if (ifrm.src.indexOf("apiOn=true") === -1) 
       if (ifrm.src.indexOf("?") === -1) 
           ifrm.src += '?apiOn=true';
       else
           ifrm.src += '&apiOn=true';   
    if (typeof _tealium_VZ.videoPlayer == "undefined") {
        _tealium_VZ.init();
    }
}, false);
  1. 最后确保根据您引用的 Tealium 文档，页面上也加载了 vzaar client.js 脚本

在此处输入图像描述

如果开发人员没有将其添加到页面，这是一个以动态方式添加它的片段。您可以将其添加到“预加载器”扩展代码的顶部

(function (a, b, c, d) {
    a = '//player.vzaar.net/libs/flashtakt/client.js';
    b = document;
    c = 'script';
    d = b.createElement(c);
    d.src = a;
    d.type = 'text/java' + c;
    d.async = true;
    a = b.getElementsByTagName(c)[0];
    a.parentNode.insertBefore(d, a)
})();

因此，按照您的自定义代码逻辑，这里有一个完整的 vzaar 跟踪代码片段，用于 Tealium 中的预加载器扩展。

(function (a, b, c, d) {
    a = '//player.vzaar.net/libs/flashtakt/client.js';
    b = document;
    c = 'script';
    d = b.createElement(c);
    d.src = a;
    d.type = 'text/java' + c;
    d.async = true;
    a = b.getElementsByTagName(c)[0];
    a.parentNode.insertBefore(d, a)
})();

var video_events = ["playState", "progress", "interaction"];  // Possible values are "playState", "progress" and/or "integration"
var milestone_percentages = ["10", "20", "30", "40", "90"];  // These must be rounded to the nearest 10
var player_element_id = "video";
var player_type = "iframe"; // Possible values are "iframe" or "html"

var fireEvent = true;
