Jquery multidimensional array not working -

-

i'm trying multidimensional array in jquery.

var exclude_array = {};  $(this).siblings("tr[data-id='" + id + "']").each(function() {     var id = $(this).attr("data-id");     var item_id = $(this).children("td:eq(3)").find("input[name='exclude']").attr("data-item_id");     exclude_array[id][] = item_id; });

i error uncaught syntaxerror: unexpected token ], exclude_array[id][] how solve?

it seems you're trying push item_id exclude_array. array[] syntax not used in javascript. instead, must use .push().

before that, make sure key defined , array.

if (exclude_array[id] === undefined)     exclude_array[id] = []; exclude_array[id].push(item_id);
