闪存包不当

Question

我有一个由几个 swf 和播放器组成的 SCORM 包。但是，当用户从 LMS 启动内容时，播放器初始化不正确或损坏，当然它无法正常工作和发挥应有的作用。有一个包的控制台日志可能会给出一个想法。

日志显示课程正常启动。 “错误”实际上是正确的行为：如果课程是 ab-initio（首次启动），请求书签 (cmi.location) 将导致错误。没有书签，因为还没有创建。

如果您希望课程有书签——即您正在重新启动课程，但它仍然表现得好像是从头开始——我猜你没有正确使用 Commit（scorm.save() 在此包装中）将数据发布到 LMS 后，and/or 在关闭课程之前不会发布 Terminate（此包装中的 scorm.quit）。

如果您的课程检查 cmi.entry 并看到 ab-initio，则无需查找书签。您应该使用条件语句来防止错误并减少 LMS 和课程之间的交流：

var bookmark = "my default";
var entry = scorm.get("cmi.entry");
var location; //wait for it...

if(entry !== "ab-initio"){

    //not querying cmi.location unless we're sure this isn't the first visit
    location = scorm.get("cmi.location");

    //Wrapping in a conditional in case cmi.location returns false or an empty string
    if(location){ bookmark = location; }

}
