how to pass two dimensional array to another function javascript -

i want header function main headers , sub headers 2 dimensional array. , pass array function.because want check print value exact match main header under subheader.

i declare 2 dimensional array below function. this,

   var code = [[]];   

headers function main headers assign subcategory , sub headers code. call 2 dimensional array this,

   if (tmp === free['b'][y].subcategory) {                 html += '<td hidden="true">' + free['b'][y].code + '</td>';                 html += '<td>' + free['b'][y].code + '</td>';                 -------------------------------------                 code= [ free['b'][y].code];                --------------------------------------               // alert(code [code]); [cryspy,mmnuts cryspy,mmjhf  cryspy,bbghr bar,ffata bar,yjkou.....etc]               }             else {                  html += '<td></td>';                 html += '<td hidden="true">' + free['b'][y].code + '</td>';                 html += '<td>' + free['b'][y].code + '</td>';                 tmp = free['b'][y].subcategory; 

then call array function values sub headers.

       (var = 0; < code.length; i++) {                //                //  alert(code.length); display: 324               (var k = 0; k < cat[i].length; k++) {              //alert(cat[i].length);//display 2                     (var y = 0; y < order['rd'][x].qty.length; y++) {    // alert("code1 ==  " + code[i] + " , code2 ==  " + order['rd'][x].qty[y].code); display code1==crspy,mmkhh code2===jklll         //  console.log(code[i] === order['rd'][x].qty[y].code);         // alert(order['rd'][x].qty.length);                         if (code[i] === order['rd'][x].qty[y].code) {                          //alert(order['rd'][x][y].code);                             order_detail += '<td style="border-bottom: 1px solid black; border-right:1px solid black; padding: 3px; text-align:right">' + order['rd'][x].qty[y].qty + '</td>';                             break;                         } else {                             order_detail += '<td style="border-bottom: 1px solid black; border-right:1px solid black; padding: 3px; text-align:right">0</td>';                             break;                         }                        }                     }                } 

but not print qty.is 2 dimentional array wrong ...or?
