javascript - jQuery Create Multidimensional Array -

-

i having heck of time trying figure out how create multidimensional array in jquery.

i instantiate array outside of loop. 

 <script>  var myarray = [];  </script>

inside of loop want add array elements. 

 = 0  [loop start]       <script>       myarray[i][$row[sku]] = $row[qty]; // sku might repeated cause issue? see in error below "295518" repeated...       <script>  [loop end]

in source code looks this: 

 <script>  myarray[ 1 ][ 295518 ] = 122;  </script>

then run @ end outside loop...

 <script>  console.log( myarray );  </script>

i error in console: 

uncaught typeerror: cannot set property '295518' of undefined  uncaught typeerror: cannot set property '70252' of undefined  uncaught typeerror: cannot set property '295518' of undefined

what doing wrong in setting array? thanks!

you can so:

var = []; a[0] = [1,2,3];  a[1] = [4,5,6];   a[1][1] 5
