I have been working on a custom input wrapper that adds error text handling among other things. The problem is I cannot reset the model values, from inspecting the scopes the outside scopes get updated on the reset. The inner scope of the directive does not and I am not sure why.
Changeing the ng-model watch in the directive from scope.$watch(ngModel, function() { to scope.$watch('ngModel', function() { causes the reset to work but then the reset does not work when the viewValue is invalid, the reset should work in this case as well.
Am I doing something terribly wrong? Code below reporoduces the problem.
var app = angular.module('app', []);
app.directive('myInput', function() {
return {
restrict: "E",
require: "ngModel",
template: $('#myInput').html(),
scope: {
"ngModel": "=",
"name": "@",
"type": "@",
"label": "@",
"errorLabel": "@",
"placeholder": "@"
},
link: function(scope, element, attributes, ngModel) {
scope.$watch('ngModel', function() {
scope.value = scope.ngModel;
console.log('got value: ' + scope.value);
});
scope.$watch('value', function() {
if(scope.value) {
ngModel.$setViewValue(scope.value);
}
});
}
};
});
app.controller('user', ['$scope', function($scope) {
$scope.currentUser = {
email: "[email protected]"
};
$scope.resetUser = function() {
console.log('resetting user');
console.log($scope.user);
$scope.user = angular.copy($scope.currentUser);
console.log($scope.user);
};
$scope.submitUser = function(user) {
console.log('submitting user');
console.log(user);
};
$scope.resetUser();
}]);.error {
color: red;
}
.my-input {
border: 5px solid transparent;
}
.ng-invalid.my-input {
border: 5px solid red;
