ganesha < - > scorm 2004：choice controlmode？(ganesha <--> scorm 2004 : choice controlmode?)

 我需要使用scorm 2004的选择控制模式，所以我做了这个非常基本的测试： 
 

 这是我的表现：

 在第1页，我连接到API并成功获取用户名。 
 

 点击后，我尝试使用此js代码转到第2页： 
 

var scorm = pipwerks.SCORM;

$( document ).ready( init );

function init()
{
    scorm.version = "2004";

    connect();

    var learnerName = getValue( "cmi.learner_name" );

    $( "#Name" ).html( "Bonjour " + learnerName + " !!!" );

    $( "#goto2" ).click( goto2 );

    $( window ).unload( disconnect );
}

function goto2()
{
    if( getValue( "adl.nav.request_valid.choice.{target=page2}" ) == "true" )
    {
        setValue( 'adl.nav.request', '{target=page2}choice' );
        disconnect();
    }

    /* if( getValue( "adl.nav.request_valid.continue" ) == "true" )
    {
        setValue( 'adl.nav.request', 'continue' );
        disconnect();
    } */
}

function connect()
{
    if( !scorm.connection.isActive )
    {
        var isSuccess = scorm.init();               
        var msg = "Connexion : " + ( ( isSuccess )? "succès" : "échec" );
        log( msg, isSuccess );
    }
}

function disconnect()
{
    if( scorm.connection.isActive )
    {
        var isSuccess = scorm.quit();               
        var msg = "Déconnexion : " + ( ( isSuccess )? "succès" : "échec" );
        log( msg, isSuccess );
    }
}

function save()
{
    if( scorm.connection.isActive )
    {
        var isSuccess = scorm.save();               
        var msg = "Sauvegarde : " + ( ( isSuccess )? "succès" : "échec" );
        log( msg, isSuccess );
    }
}

function getValue( parameter )
{
    var value = null;

    if( scorm.connection.isActive )
    {
        value = scorm.get( parameter );
        var msg = "Get " + parameter + " : " + ( ( value )? value : "échec" );
        var isSuccess = ( value )? true : false;
        log( msg, isSuccess );
    }

    return value;
}

function setValue( parameter, value )
{
    if( scorm.connection.isActive )
    {
        var isSuccess = scorm.set( parameter, value );
        var msg = "Set " + parameter + " = " + value + " : " + ( ( isSuccess )? "succès" : "échec" );
        log( msg, isSuccess );
    }
}

function log( msg, isSuccess )
{
    $( "#console" ).append( "<div style=\"color:" + ( ( isSuccess )? "blue" : "orangered" ) + ";\">" + msg + "</div>" );
}

 

 scorm.set（'adl.nav.request'，'{target = page2} choice'）不起作用，它返回一个空字符串。 
 

 为什么不起作用？ 可能是js中的错误或清单中的错误树？ 
 

 我没有成功找到好的语法，我不确定我的探索方式...... 

I need to use choice controlmode of scorm 2004, so I have done this very basic test :

On page1, I connect to API and succeed to get username.
 

On click, I try to go to page 2 with this js code :
 

var scorm = pipwerks.SCORM;

$( document ).ready( init );

function init()
{
    scorm.version = "2004";

    connect();

    var learnerName = getValue( "cmi.learner_name" );

    $( "#Name" ).html( "Bonjour " + learnerName + " !!!" );

    $( "#goto2" ).click( goto2 );

    $( window ).unload( disconnect );
}

function goto2()
{
    if( getValue( "adl.nav.request_valid.choice.{target=page2}" ) == "true" )
    {
        setValue( 'adl.nav.request', '{target=page2}choice' );
        disconnect();
    }

    /* if( getValue( "adl.nav.request_valid.continue" ) == "true" )
    {
        setValue( 'adl.nav.request', 'continue' );
        disconnect();
    } */
}

function connect()
{
    if( !scorm.connection.isActive )
    {
        var isSuccess = scorm.init();               
        var msg = "Connexion : " + ( ( isSuccess )? "succès" : "échec" );
        log( msg, isSuccess );
    }
}

function disconnect()
{
    if( scorm.connection.isActive )
    {
        var isSuccess = scorm.quit();               
        var msg = "Déconnexion : " + ( ( isSuccess )? "succès" : "échec" );
        log( msg, isSuccess );
    }
}

function save()
{
    if( scorm.connection.isActive )
    {
        var isSuccess = scorm.save();               
        var msg = "Sauvegarde : " + ( ( isSuccess )? "succès" : "échec" );
        log( msg, isSuccess );
    }
}

function getValue( parameter )
{
    var value = null;

    if( scorm.connection.isActive )
    {
        value = scorm.get( parameter );
        var msg = "Get " + parameter + " : " + ( ( value )? value : "échec" );
        var isSuccess = ( value )? true : false;
        log( msg, isSuccess );
    }

    return value;
}

function setValue( parameter, value )
{
    if( scorm.connection.isActive )
    {
        var isSuccess = scorm.set( parameter, value );
        var msg = "Set " + parameter + " = " + value + " : " + ( ( isSuccess )? "succès" : "échec" );
        log( msg, isSuccess );
    }
}

function log( msg, isSuccess )
{
    $( "#console" ).append( "<div style=\"color:" + ( ( isSuccess )? "blue" : "orangered" ) + ";\">" + msg + "</div>" );
}

 

the scorm.set( 'adl.nav.request', '{target=page2}choice' ) doesn't work, it return an empty string.
 

Why is it not working ? an error in js or a bad tree in manifest maybe ?
 

I'm not succeed to find the good syntax and I'm not sure anymore to what way I have explore...

 这是我在控制台应用程序中尝试过的，并按预期工作： 
 

namespace Q7122388
{
    #region Imports

    using System;
    using System.Collections.Generic;
    using System.ComponentModel.DataAnnotations;
    using System.Data.Entity;
    using System.Linq;

    #endregion

    public class Product
    {
        [Key]
        public int Id { get; set; }

        public virtual string Name { get; set; }

        public virtual ICollection<Category> Categories { get; set; }
    }

    public class Category
    {
        [Key]
        public int Id { get; set; }

        public virtual string Name { get; set; }

        public virtual ICollection<Product> Products { get; set; }
    }

    public class DatabaseContext : DbContext
    {
        public virtual DbSet<Product> Products { get; set; }
        public virtual DbSet<Category> Categories { get; set; }

        protected override void OnModelCreating(DbModelBuilder modelBuilder)
        {
            modelBuilder.Entity<Product>()
                .HasMany<Category>(m => m.Categories)
                .WithMany().Map(m =>
                    m.MapLeftKey("ProductId")
                    .MapRightKey("CategoryId")
                    .ToTable("ProductCategories"));
            base.OnModelCreating(modelBuilder);
        }
    }

    class Program
    {
        static void Main(string[] args)
        {
            Database.SetInitializer(new DropCreateDatabaseAlways<DatabaseContext>());
            using (var context = new DatabaseContext())
                context.Database.Initialize(true);
        }
    }
}

    }

    public class Category
    {
        [Key]
        public int Id { get; set; }

        public virtual string Name { get; set; }

    public class DatabaseContext : DbContext

        public virtual DbSet<Product> Products { get; set; }

        protected override void OnModelCreating(DbModelBuilder modelBuilder)
        {
            modelBuilder.Entity<Product>()
                .HasMany<Category>(m => m.Categories)
                .WithMany().Map(m =>
                    m.MapLeftKey("ProductId")
                    .MapRightKey("CategoryId")
                    .ToTable("ProductCategories"));
            base.OnModelCreating(modelBuilder);
        }
    }

        static void Main(string[] args)
        {
            Database.SetInitializer(new DropCreateDatabaseAlways<DatabaseContext>());
            using (var context = new DatabaseContext())
                context.Database.Initialize(true);
