Convert Switch to Object

I have this code:

var params = Spry.Utils.getLocationParamsAsObject();
theLeague = params.league;
switch (theLeague)
{
case 'boyswinter':
    var Soccer = new Spry.Widget.TabbedPanels("Soccer", {defaultTab: 0}); 
  break;
case 'girlswinter':
    var Soccer = new Spry.Widget.TabbedPanels("Soccer", {defaultTab: 1}); 
  break;
default:
    var Soccer = new Spry.Widget.TabbedPanels("Soccer", {defaultTab: 0}); 
}

I'd like to use an alternative to switch, and I found this bit of code to use as a guide:

var whatToBring = {
    "Sunny" : "Sunscreen and hat",
    "Rain" : "Umbrella and boots",
    "Cold" : "Scarf and Gloves",
    "Default" : "Play it by ear"
}
var gear = whatToBring[weather] || whatToBring["D开发者_Python百科efault"];

However, I can't figure out how to swap in my stuff so that it works. It should be easy, but as a JS beginner, I can't wrap my head around it. Any help would be greatly appreciated. Thanks.

I don't know if using an object is the best method here, but in any event, this should work.

var leagueMap = {
    "boyswinter" : function(){ return new Spry.Widget.TabbedPanels("Soccer", {defaultTab: 0}); },
    "girlswinter" : function(){ return new Spry.Widget.TabbedPanels("Soccer", {defaultTab: 1}); },
    "Default" : function(){ return new Spry.Widget.TabbedPanels("Soccer", {defaultTab: 0}); }
}
var Soccer = (leagueMap[theLeague] || leagueMap["Default"])();

should be something like:

var theLeague = {
    "boyswinter" : function() { return new Spry.Widget.TabbedPanels("Soccer", {defaultTab: 0}); },
    "girlswinter" : function() { return new Spry.Widget.TabbedPanels("Soccer", {defaultTab: 1}); },
    "Default" : function() { return new Spry.Widget.TabbedPanels("Soccer", {defaultTab: 0}); },
}
var l = theLeague[league] || theLeague["Default"];

Translating from your example it would be something like this:

var SoccerFactory = {
    'boyswinter' : new Spry.Widget.TabbedPanels("Soccer", {defaultTab: 0}),
    'girlswinter' : new Spry.Widget.TabbedPanels("Soccer", {defaultTab: 1}),
    'default' : new Spry.Widget.TabbedPanels("Soccer", {defaultTab: 0})
};

var Soccer = SoccerFactory[theLeague] || SoccerFactory['default'];

Please let me know if you'd like further explantation of the concepts used. I'm unsure about which parts you are having trouble understanding.

Edit

Or even better!

var SoccerFactory = {
    'boyswinter' : new Spry.Widget.TabbedPanels("Soccer", {defaultTab: 0}),
    'girlswinter' : new Spry.Widget.TabbedPanels("Soccer", {defaultTab: 1}),
    'default' : this['boyswinter']
};

var Soccer = SoccerFactory[theLeague] || SoccerFactory['default'];

Repeating yourself is bad. =)
