angularjs - Update ng-model from controller -

hopefully pretty simple, brain isn't working @ moment...

i have form this:

<div class="control-group">     <label class="control-label" for="cn_pref_name_j04">name on card:</label>         <div class="controls">             <input type="text" name="cn_pref_name_j04" id="cn_pref_name_j04" ng-model="formdata.cn_pref_name_j04"  />         </div> </div> 

and have basic controller this:

app.controller("closecallspoke", function($scope){     $scope.formdata = angular.copy($scope.data); } 

this automatically assign entire formdata object whatever in data object.

how can assign cn_pref_name_j04?

i tried:

$scope.formdata.cn_pref_name_j04 = angular.copy($scope.data.cn_pref_name_j04); 

but "$scope.formdata undefined.

please help.

try this:

$scope.formdata = { cn_pref_name_j04 : angular.copy($scope.data.cn_pref_name_j04) }; 

that way $scope.formdata initialized object has cn_pref_name_j04 property you're looking for
