my html code

<select name="important[]" class="form-control" multiple="" required>         <option ng-selected="important_selection.important.find(item => item.id === important.id)" ng-repeat="important in importants_series.important" value="{{important.id}}">{{important.name}}</option>     </select>

now want search id in array , if true selected. have issue in ng-selected

any appreciating thanks.

you should using ng-options , ng-model in select easy data binding.

<select name="important[]" class="form-control" multiple="" required      ng-options="important.name important in importants_series.important"      ng-model="important_selection.client_data.important"></select>

unfortunately ng-model checks object reference equality, need additional step reassigning data selection array itself

  var oldarray = $scope.important_selection.client_data.important;    $scope.important_selection.client_data.important = [];    oldarray.foreach(function(item) {     var refitem = $scope.importants_series.important.find(function(i) {       return i.id == item.id;     });      $scope.important_selection.client_data.important.push(refitem);   });

or can assign new array instead.

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
