javascript - The name <js_variable> does not exist in the current context -

-

i have following model set there list<string> trying add value to:

public class newshipmentmodel {     ...     public list<string> units_selected { get; set; }      public newshipmentmodel()     {         units_selected = new list<string>();     } }

in view, have eventlistener set on checkbox trying take value of checkbox , either add or remove list using javascript , razor:

    (var = 0; < unitcheckboxes.length; i++) {         unitcheckboxes[i].addeventlistener("change", function () {              var addition = 0;             var unit_serial = this.value;             var curr_val = (this.name == "base") ? parseint($("#total-bases-selected").text()) : parseint($("#total-clients-selected").text());              if (this.checked) {                 addition = 1;                 @model.units_selected.add(unit_serial);  // error here             }  else {                 addition = -1;                 @model.units_selected.remove(unit_serial);  // error here             }              curr_val = curr_val + addition;              if (this.name == "base")                 $("#total-bases-selected").text(curr_val);             else                 $("#total-clients-selected").text(curr_val);          }, false);     }

however, trying add or remove value fails have marked error here in comments. issue cannot access unit_serial seems out of scope razor:

the name unit_serial not exist in current context

how access variable? possible?

edit: note data passed controller via submit button , http post. i'm not sure how populate list and/or inject data in rest of form.

it seams you're confusing server , client code. razor part executes on server. javascript - on client. therefore can't 

//note unit_serial doesn't exist when you're calling add method because //executes during razor view generation on server. //all javascript code executes after client receive generated view. @model.units_selected.add(unit_serial);

in middle of javascript code, because doesn't make sense. when change event handler fires on checkboxes: send server updating.

for making work consider create 1 more mvc action , use ajax passing data server.

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 $row): ?> <div id="<?=$...
