Moodle中的Javascript &SCORM1.2

Question

我是从flash发布html，这是flash +SCORM1.2，我的html包含.swf，因为player .swf player会有菜单和学生从这个swf导航页面，所以课程的状态应该在学生到达最后一页时完成，但是我发生了什么呢？当第一次访问课程并关闭>>时，课堂状态是不完整的，这是正确的，但是当第二次打开课程时，状态更改为已完成，第三次更改为不完整的..4th时，我不知道发生了什么，这是我使用的javascript函数：

var g_nFindAPITries = 0;
var g_objAPI = null;
var g_bInitDone = false;
var g_bFinishDone = false;
var g_bSCOBrowse = false;
var g_dtmInitialized = new Date(); // will be adjusted after initialize
var g_bMasteryScoreInitialized = false;
function AlertUserOfAPIError(strText) {
    if (g_bShowApiErrors) {
        var s = strText + "\n\n" + g_strDisableErrorMsgs;
        if (!confirm(s)){
            g_bShowApiErrors = false
        }
    }
}

function ExpandString(s){
    var re = new RegExp("%","g")
    for (i = arguments.length-1; i > 0; i--){
        s2 = "%" + i;
        if (s.indexOf(s2) > -1){
            re.compile(s2,"g")
            s = s.replace(re, arguments[i]);
        }
    }
    return s
}
function FindAPI(win) {
    while ((win.API == null) && (win.parent != null) && (win.parent != win)) {
        g_nFindAPITries ++;
        if (g_nFindAPITries > 500) {
            AlertUserOfAPIError(g_strAPITooDeep);
            return null;
        }
        win = win.parent;
    }
    return win.API;
}
function APIOK() {
    return ((typeof(g_objAPI)!= "undefined") && (g_objAPI != null))
}
function SCOInitialize() {
var err = true;
    if (!g_bInitDone) 
        {


        if ((window.parent) && (window.parent != window)){
            g_objAPI = FindAPI(window.parent)
        }
        if ((g_objAPI == null) && (window.opener != null))  {
            g_objAPI = FindAPI(window.opener)
        }
        if (!APIOK()) {
            AlertUserOfAPIError(g_strAPINotFound);
            err = false
        } 
                else
                {
            err = g_objAPI.LMSInitialize("");
            if (err == "true") 
                         {
                g_bSCOBrowse = (g_objAPI.LMSGetValue("cmi.core.lesson_mode") == "browse");
                if (!g_bSCOBrowse)
                                   {
                    if (g_objAPI.LMSGetValue("cmi.core.lesson_status") == "not attempted")
                                           {
                        err = g_objAPI.LMSSetValue("cmi.core.lesson_status","incomplete")
                       }
                   }
            }
                        else 
                        {
                AlertUserOfAPIError(g_strAPIInitFailed)
            }
        }
          if (typeof(SCOInitData) != "undefined") 
                   {
            // The SCOInitData function can be defined in another script of the SCO
            SCOInitData()
           }
        g_dtmInitialized = new Date();
    }
    g_bInitDone = true;

    return (err + "") // Force type to string
}
function SCOFinish() {
    if ((APIOK()) && (g_bFinishDone == false)) {
        SCOReportSessionTime()
        if (g_bSetCompletedAutomatically){
            SCOSetStatusCompleted();
        }
        if (typeof(SCOSaveData) != "undefined"){
            // The SCOSaveData function can be defined in another script of the SCO
            SCOSaveData();
        }
        g_bFinishDone = (g_objAPI.LMSFinish("") == "true");
    }
    return (g_bFinishDone + "" ) // Force type to string
}
// Call these catcher functions rather than trying to call the API adapter directly
function SCOGetValue(nam)           {return ((APIOK())?g_objAPI.LMSGetValue(nam.toString()):"")}
function SCOCommit()                    {return ((APIOK())?g_objAPI.LMSCommit(""):"false")}
function SCOGetLastError()      {return ((APIOK())?g_objAPI.LMSGetLastError():"-1")}
function SCOGetErrorString(n)   {return ((APIOK())?g_objAPI.LMSGetErrorString(n):"No API")}
function SCOGetDiagnostic(p)    {return ((APIOK())?g_objAPI.LMSGetDiagnostic(p):"No API")}
//LMSSetValue is implemented with more complex data management logic below
var g_bMinScoreAcquired = false;
var g_bMaxScoreAcquired = false;
// Special logic begins here
function SCOSetValue(nam,val){
    var err = "";
    if (!APIOK()){
            AlertUserOfAPIError(g_strAPISetError + "\n" + nam + "\n" + val);
            err = "false"
    } else if (nam == "cmi.core.score.raw") err = privReportRawScore(val)
    if (err == ""){
            err = g_objAPI.LMSSetValue(nam,val.toString() + "");
            if (err != "true") return err

        g_nSCO_ScoreMin = val
    }
    else if (nam == "cmi.core.score.max"){
        g_bMaxScoreAcquired = true;

    }
    return err
}

这是body html中的

<body bgcolor="#ffffff" onload="SCOInitialize()" onunload="SCOFinish()" onbeforeunload="SCOFinish()" >

那么，为什么它的交换一次又一次地不完整和完成--我试图为cmi.core.lesson_status设置值，但它不起作用

Answer 1

我将把调试的重点放在g_bSetCompletedAutomatically变量上。设置一个监视，看看您退出课程时代码是否正在调用SCOSetStatusCompleted()。而且，在您提供的示例中看不到g_bSetCompletedAutomatically的原始值或SCOSetStatusCompleted()的代码，就很难给出更多的方向。但这将显示您将lesson_status设置为已完成的位置，因为我没有看到任何其他代码设置它完成在代码中的任何其他位置。

对于课程完成后的问题，您可能需要查看的另一件事是在您的SCOInitialize()中，因为这是我看到您的代码设置lesson_status的唯一地方。您需要查看lesson_mode是否返回、浏览、和lesson_status是否返回，而不是尝试，以查看这段代码是否将课程设置为不完整。另外，当一个课程处于浏览模式时，RTE和LMS应该忽略并无论如何调用SetValue。

g_bSCOBrowse = (g_objAPI.LMSGetValue("cmi.core.lesson_mode") == "browse");
if (!g_bSCOBrowse)
    {
        if (g_objAPI.LMSGetValue("cmi.core.lesson_status") == "not attempted")
        {
            err = g_objAPI.LMSSetValue("cmi.core.lesson_status","incomplete")
        }
    }
