javascript - Use ng-value for radio button (angularjs) -


i'am new angularjs.. want make selection using radio button , save boolean value. when use ng-value, value save database null. code html. 

<label><input type="radio" ng-model="information" ng-value="true" name="maklumat">yes</label><br /> <label><input type="radio" ng-model="information" ng-value="false" name="maklumat">false</label>

ng-value expects angularjs expression ngmodel be set when radio selected.

and expressions being case-sensitive, if set ng-value="true" sets have in ng-model true, if have ng-value="true", tries $scope.true doesn't find , ng-model gets set null.

here's example.

angular.module('radioexample', [])    .controller('examplecontroller', ['$scope', function($scope) {      $scope.true = "something totally different"      $scope.specialvalue = {        "id": "12345",        "value": "green"      };    }]);
<!doctype html>  <html lang="en">    <head>    <meta charset="utf-8">    <title>example - example-radio-input-directive-production</title>    <script src="//code.angularjs.org/snapshot/angular.min.js"></script>  </head>    <body ng-app="radioexample">      <form name="myform" ng-controller="examplecontroller">      <label>      <input type="radio" ng-model="color.name" ng-value="specialvalue">      specialvalue    </label><br/>      <label>      <input type="radio" ng-model="color.name" ng-value="true">      true    </label><br/>    <label>      <input type="radio" ng-model="color.name" ng-value="true">      true    </label><br/><br/>      <tt>color = {{color.name | json}}</tt><br/>    </form>    <br><br/><br/> note `ng-value="specialvalue"` sets radio item's value value of `$scope.specialvalue`.  </body>    </html>
