Jquery functions with variable arrays -

i have function produces random number game. running function 8 times. instead of copying function 8 times , renaming variables, want streamline it.

    function card1nums() {             card1array = [];             var iteration1=0;             while (iteration1 < 25) {                 num1=getcardnum();                   //look see if number exists                 if($.inarray(num1,card1array) == -1){                     //number not found add array                     card1array.push(num1);                     iteration1++;                 }             }return card1array;         }          function card2nums() {             card2array = [];             var iteration2=0;             while (iteration2 < 25) {                 num2=getcardnum();                   //look see if number exists                 if($.inarray(num2,card2array) == -1){                     //number not found add array                     card2array.push(num2);                     iteration2++;                 }             }return card2array;         }           $("#draw").click(function() {             drawnumbers();             card1nums();             card2nums();              var jsondealerarray = json.stringify(drawarray);             var jsoncard1array = json.stringify(card1array);             var jsoncard2array = json.stringify(card2array);              $.ajax({                 url: "includes/dealerpicks.php",                 type: 'post',                 data: {dealer:jsondealerarray,                          card1:jsoncard1array,                          card2:jsoncard2array,                          },                 datatype: "json",                 async: false,                 cache: false,             });            }); 

in code above creating numbers card1. if 8 times, copy function , rename variable respectively card2nums, card3nums.....

i assumed alter code when call function cardnums() add parameter of x , call cardnums(x); , use x in array names array stored in database. card1array stored in card1 in database , forth.

i reading objects not quite sure way go. since repeatative function know there better way it. think?

edit: see going if 8 times. call 8 separate function exact same thing rename arrays , pick new numbers.

please this:

as concerns basic javascript-knowleage please ask if don't understand in comment below.

  function cardnums() {      var cardarray = [];      var iteration1 = 0;      while (iteration1 < 25) {        num1 = getcardnum();        //look see if number exists        if ($.inarray(num1, cardarray) == -1) {          //number not found add array          cardarray.push(num1);          iteration1++;        }      }      return cardarray;    }        $("#draw").click(function() {      drawnumbers();      var card1array = cardnums();      var card2array = cardnums();      //var card3array = cardnums();      //var card4array = cardnums();      //var card5array = cardnums();      //var card6array = cardnums();      //var card7array = cardnums();      //var card8array = cardnums();        var jsondealerarray = json.stringify(drawarray);      var jsoncard1array = json.stringify(card1array);      var jsoncard2array = json.stringify(card2array);        $.ajax({        url: "includes/dealerpicks.php",        type: 'post',        data: {          dealer: jsondealerarray,          card1: jsoncard1array,          card2: jsoncard2array,        },        datatype: "json",        async: false,        cache: false,      });          });
