how to get the first element of an array which passed to the smarty?

Question

how to get the first element of an array which passed to smarty template page, and treat it some way in smarty page.

i use this way but it's not working.

$("item_".{$categories.category_id[1]}).addClass("active");

try `[0]`? no idea if you can actually access elements by index like that in smarty though. — user428517, Jul 30 '13 at 13:57

What you're trying is correct, but try this syntax as well: `$categories.category_id.1` (if 1 is the actual index of your first element, and not 0) — periklis, Jul 30 '13 at 14:04
The smarty tag renders server side so the jquery selector would look like so `$("item_".5)`, which is not valid. You could do it like this instead `$("item_{$categories.category_id[1]}")`. The first element can be accessed like this `{$categories.category_id|reset}` (tested with smarty 3.1.14) — sofl, Jul 30 '13 at 15:42

try with concatenating strings with the + operator

For example:

var myId = "domElement";
$("#"+myId).addClass("active");
