jquery - JavaScript Objects and Arrays -


i'm having function adding 16 football teams highest number of points in 4 groups. every group must have 4 teams , must not have more 2 teams same league.

i've added property in every team object league name in arr , sorted highest number of points.

i can't figure out how put condition 1 group can't have more 2 teams 1 league?

jsfiddle link: http://jsfiddle.net/6jdjjqfw/

code: 

var tournaments = ['bundes', 'league1', 'premier', 'primera', 'seriea']; var teams = []; var groups = [];  function getdata(id) {     var url = "http://api.helloworld.ba/n/app.php?f=" + id;     return $.getjson(url); }  var ajax = []; (i = 0; < tournaments.length; i++) {     ajax.push(getdata(tournaments[i])); }  $.when.apply($, ajax).done(function () {      (var = 0, len = arguments.length; < len; i++) {         teams.push(arguments[i][0]);     }      creategroups(teams); });  function creategroups(teams) {     var          arr = [],         arra = [],         arrb = [],         arrc = [],         arrd = [],         br = 1;       (i = 0; < teams.length; i++)     (var j = 0; j < teams[i].standing.length; j++) {         teams[i].standing[j].league = teams[i].leaguecaption;         arr.push(teams[i].standing[j]);     }     arr.sort(function (a, b) {         return b.points - a.points;     });      (i = 0; < 4; i++)      {             arra.push(arr[i].teamname);                arrb.push(arr[i+4].teamname);              arrc.push(arr[i+8].teamname);               arrd.push(arr[i+12].teamname);       }     groups.push(arra);     groups.push(arrb);     groups.push(arrc);     groups.push(arrd);     console.log(teams);    console.log(arr);      console.log("groups listed:\n\n");     for(i=0; i<groups.length;i++)     {         console.log("group " + br +" " + groups[i]);         br++;     } }

try doing :

  • iterate on teams (16 items)in while loop

  • use switch on random int between 1 , 4 choose group of each team

    function getrandomint(min, max) {     return math.floor(math.random() * (max - min + 1)) + min; }

  • add method test if team has 2 member of league before adding group. test if group not full (4 members) if method returns false don't add team group , don't increase team counter, you'll new random number in loop.
