I am new to parsers and formatters. I have a directive that will be doing validation on change of the model.One way to do this is the $watch but from what I understand that is not a good way since it allows the model to be updated.
So I was looking at parsers and tried this code
app.directive('myDirective', function($compile) {
return {
restrict: 'E',
require: 'ngModel',
scope: {
},
link: function($scope, elem, attr, ctrl) {
console.debug($scope);
ctrl.$formatters.push(function(value) {
console.log("hello1");
return value;
});
ctrl.$parsers.unshift(function(value) {
debugger;
console.log("hello");
return value;
});
}
};
});
But the parser function is never called. The formatter is called once. Please see the plunkr .Can anyone tell me what I am doing wrong ,why is the parser function not getting called when i type in the textbox ?
This is a late response, but for reference:
I think you where missing the "glue" that will call the $parsers while ui changes occurs. This should be something like:
app.directive('myDirective', function($compile) {
return {
restrict: 'E',
require: 'ngModel',
scope: {
},
link: function($scope, elem, attr, ctrl) {
console.debug($scope);
ctrl.$formatters.push(function(value) {
console.log("hello1");
return value;
});
ctrl.$parsers.unshift(function(value) {
return value;
});
scope.$watch('directive model here', function() {
ctrl.$setViewValue(<build model from view here>);
});
}
};
});
