returning element from a string

Hi everybody ,

I have a dropdownlist:

[code]
select id="weekId" onchange="Selectedchange();" name="weekId" class="valid">

<option value="{ Maandag = 2-1-2012, Dindsdag = 3-1-2012, Wendsday = 4-1-2012, Thursday = 5-1-2012, Fryday = 6-1-2012, Saterday = 7-1-2012, Sunday = 8-1-2012 }">1option>

<option value="{ Maandag = 9-1-2012, Dindsdag = 10-1-2012, Wendsday = 11-1-2012, Thursday = 12-1-2012, Fryday = 13-1-2012, Saterday = 14-1-2012, Sunday = 15-1-2012 }">2option>

<option value="{ Maandag = 16-1-2012, Dindsdag = 17-1-2012, Wendsday = 18-1-2012, Thursday = 19-1-2012, Fryday = 20-1-2012, Saterday = 21-1-2012, Sunday = 22-1-2012 }">3option>

[/code]

But how to get with JQuery for example only: Dinsdag?

I have this:

[code]
function Selectedchange() {
    var elemlent = $("#txtBox").val($("#weekId").val().toString().split(","));
    var string = $find("Dindsdag"); //.attr("selected",0);
    print(string);
}
[/code]

but that doesnt seem to work.
