javascript - Value not changing when radio button is pressed - AngularJS -

-

what i'm trying when product selected different types of product brought in browser. here's got:

script.js

function showctrl($scope,  $http) { $scope.products = [  {     "category":"pens",     "label":"p1",     "images":"d-u-b/pens.png" }, {     "category":"cozies",     "label":"p2",     "images":"d-u-b/cozie.png" } ]; $scope.prod = {"name": "cozies"}; $scope.typselect = 'plain'; $http.get("products/"+$scope.prod.name+".json").success(function(data){     $scope.type = data;  }); }

customo.php(code snippet being called)

<div class="pro" ng-repeat="product in products">  <label for="{{product.label}}" class="p">   <input id="{{product.label}}" type="radio" ng-model="prod.name" name="name" value="{{product.category}}"/>   <h3>{{product.category}}</h3><img ng-src="{{product.images}}" alt="{{product.category}}"/>  </label> </div>

my problem prod.name not changing in js , not calling correct json file. displayed prod.name in html , changes correctly when click radio button types not change according product selected.

can see i'm doing wrong , how fix it?

thats because javascript code not paying attention changes of variable. make controller observe prod.name need use $watch method of $scope variable.

$scope.$watch('prod.name', function () {   $http.get("products/"+$scope.prod.name+".json").success(function(data){     $scope.type = data;   }); });

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