Simple number picking game (jQuery)

Question

First, hello. Great forum/site here :)

I have been working on my personal site for whole weekend and now I'm stuck with this "game" idea which I would like to add my site. I know HTML and CSS pretty well but I'm quite new with JS/jQuery.

Let me try to explain from user experience what (s)he should be able to do with the "game".

There is 10 numbers from where users selects 3 numbers and also 2 extra numbers from new numbers list (11-15). These selected numbers then go to another div (or something). From this point I can do my stuff with PHP. But I'm completly stuck with this part. I know, I know its quite simple but braing must be frozen from coding my site for 48hours :D

Select 5 numbers from these: 1-2-3-4-5-6-7-8-9-10 Select 2 additional numbers from there: 11-12-13-14-15

And those selected numbers should be shown with jQuery in div like this: Normal: 2-3-6-7-8 Extra: 12-14

User can also clear selected numbers (if (s)he wants to select different numbers all together) and/or remove one number and select new one. When the 5/2 numbers are selected all the other numbers should somehow disable so user cannot select more than 5/2 numbers.

Also it would be cool if user could randomly select the numbers (clicking some button and it automatically selects 5+2 numbers). But I have no clue how this could be done?

Now numbers selecting probably could be done with something like this?

//5 numbers
$("#mainNumbers div").click(function) {
var selectedNumber = $(this).text().clone();
$("#selectedMainNumbers").append("<div>"+selectedNumber+"</div>");
}

//2 extra numbers
$("#extraNumbers div").click(function) {
var selectedNumber = $(this).text().clone();
$("#selectedExtraNumbers").append("<div>"+selectedNumber+"</div>");
}

Clearing selection maybe like this?

$("#clearNumbers").click(function) {
    $("#selectedMainNumbers, #selectedExtraNumbers").empty();
    }

Do those look ok? Or could those done better somehow.

And now the part that I have no idea. How numbers sorting should be done? Use Arrays? For example, user first clicks number 5 and that is added to the #selectedMainNumbers div and then he selects 2 and its added to #selectedMainNumbers div aswell, and it looks like 8-3 now, but I would like to have numbers is numeric order always, so the numbers should be 3-8 format.

Also how the random number picking should be done? What about the disabling number selecting if user has already selected the needed 5 numbers?

Phew this is long post. Sorry about that. And hopefully you can give me some hint.. since my brain isnt working atm :/ Thank you. Ask if something isnt clear.

HTML:

  <div id="mainNumbers"></div> 
  <div id="extraNumbers"></div>
  <div id="selected_mainNumbers"></div> 
  <div id="selected_extraNumbers"></div>      
  <br />     <button id="generateNumbers">Generate random numbers</button>      
  <br />     <button id="clearNumbers">Clear selected</button>

CSS:

       $(clickedElement).remove(); 
    }
  }
}
// clear function

What about this: http://jsfiddle.net/ABetK/ ?

And if you want to send it to the server, use a form: http://jsfiddle.net/ABetK/1/

Edit:

It seems I didn't read all the question, so my jsfiddle doesn't do all that user1610229 wants.
