oop - Javascript: Internal array is not reset to outer objects -

-

how grant access inner properties of objects in right way? break application:

i have object handles array (simplified here):

function listmanager() {     var list = [],         add = function (element) {             list.push(element);         },         clear = function () {             list = [];         };      return {         add: add,         clear: clear,         list : list     }; };

but when using it:

var manager = new listmanager(); manager.add("something"); manager.clear(); console.log(manager.list.length); // <= outputs "1"!

stepping through code shows, within clear method, list becomes new array. outside listmanager list ist not cleared.

what doing wrong?

this because clear sets value of var list, not .list on object returned listmanager(). can use this instead:

function listmanager() {     var list = [],         add = function (element) {             this.list.push(element);         },         clear = function () {             this.list = [];         };      return {         add: add,         clear: clear,         list : list     }; }

php - render data via PDO::FETCH_FUNC vs loop -

-
i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
