Setting 2-dimensional array into input hidden field

Question

I have an array which I have another to push into in a loop

array1[ [box1, type1, 10], [box1, type2, 12] ]
array2[ [box2, type1, 10], [box2, type2, 12], [box2, type2, 12] ]

var curArray = new Array();

so in a loop:

var testarray = new Array('box1', 'type1', 10);
curArray.push(testarray);

and I have to post it so I set it in a hidden field. array.push works when I console.log(curArray) but if you set it to a hidden field by

$('hdnField').val(curArray)

it no longer become a multidimensional array.

Is there another way to do this?

is this an ajax post? if so can add data within ajax code and not need hidden field — charlietfl

try this:

$('hdnField').val(JSON.stringify(curArray));

hi there, it turns it into a string, then I will decode it in the server?

YES, you can find easily a JSON Parser library in your server language

You can try JSON.stringify()

$('hdnField').val(JSON.stringify(curArray));

Does this work?

unfortunately, it did not work. having a weird error "Unexpected token b". i'm sure they wasn't any extra syntax that i mistyped.

it's not parse but stringify. like $('#hdnField').val(JSON.stringify(curArray));
