angularjs - How to use ng-required with input type as file? -

-

i have form in angularjs image(logo) needs compulsory upload when particular check box checked,and if checkbox not selected user may upload image in case it's not compulsory. tried using ng-required conditional required functionality it's not working file input.

html

<input type="checkbox" ng-model="istrue" ng-change="ischecked()"/>

controller.js

$scope.check = false; $scope.ischecked = function() {    $scope.check = true; }

html

<input id="uploadfile" placeholder="choose file" ng-model="uploadfile" ng-required="check" />

may anyone. in advance.

i wanted file upload functionality , did follows.

hope helps.

    <form id="uploader" ng-submit="uploadimage()" role="form">         <input id="image" type="file"  required />         <input type="submit" value="upload" class="button btn-success form-control" />         <input type="reset" name="reset" value="reset" class="button btn-danger form-control" />     </form>

this ensured me on selecting file(image) in order user submit.
