Javascript object losing attribute -


i'm having bit of problem function:

function create_enemies(rows, columns) {     var i, j;      var x_position = 0;     var y_position = 0;     var id = 0;      enemies_array = new array(rows);      (i = rows - 1; >= 0; i--) {         enemies_array[i] = new array(columns);         (j = columns - 1; j >= 0; j--) {             x_position = j * (enemy_squadron_width / 4) + (ship_width / 2);             y_position = * (enemy_squadron_height / 4);              enemies_array[i, j] = {                 x : x_position,                 y : y_position,                 width : ship_width,                 height : ship_height,                 speed : 2,                 id : id             };              id++;             console.log("this one's fine: " + enemies_array[i, j].y);         }     }      (i = rows - 1; >= 0; i--) {         (j = columns - 1; j >= 0; j--) {             console.log("this one's not fine:  " + enemies_array[i, j].y);         }     } }

what's happening on first console.log, y attribute being correctly printed, on second console.log, every y in every element of array set @ 0. somehow y attribute lost between first outer for-loop , second.

i'm surely missing obvious, , starting feel little insane.

any ideas?

thank much.

edit - should mention every other attribute fine. y being reset

here go:

function create_enemies(rows, columns) {      var x_position = 0;     var y_position = 0;     var enemy_squadron_width = 100;     var enemy_squadron_height = 100;     var ship_width = 100;     var ship_height = 100;       var id = 0;      var enemies_array = new array(rows);      (var = rows - 1; >= 0; i--) {         enemies_array[i] = new array(columns);         (var j = columns - 1; j >= 0; j--) {             var x_position = j * (enemy_squadron_width / 4) + (ship_width / 2);             var y_position = * (enemy_squadron_height / 4);             enemies_array[i][j] = {                 x : x_position,                 y : y_position,                 width : ship_width,                 height : ship_height,                 speed : 2,                 id : id             };              id++;             console.log("this one's fine: " + enemies_array[i][j].y);         }     }      (var = rows - 1; >= 0; i--) {         (var j = columns - 1; j >= 0; j--) {             console.log("this one's not fine:  " + enemies_array[i][j].y);         }     } }  create_enemies(10,10);

you need acces elements of array a[i][j].
