Hy, I have a variable bound to my scope,
$scope.isSuccess = { invalidPhone : false }
And I am using a span to display a message when the variable gets true …
<form name = "myForm"> <span ng-if="isSuccess.invalidPhone && myForm.$submitted"> Please enter valid phone no. </span> </form>
Now I am calling a Js method when the form gets submitted..which validates the phone number and set
$scope.isSuccess.invalidPhone = true
Only if it is incorrect.
Now I want to reset the value of this variable to false when my span gets executed. How to do it ? Thank you

Use the ng-change
directive to update status of the flag:
<form name = "myForm"> <input name="phoneNumber" ng-model="data.num" type="text" ng-change="updateStatus(data.num)" /> <span ng-if="isSuccess.invalidPhone && myForm.$submitted"> Please enter valid phone no. </span> </form>
Every time the user changes the phone number, the function will be called:
$scope.updateStatus = function(num) { //Check phone number here });
