ctrl.$formatters runs initially when setting the model value, but not after updating it.
After reading this thread about $formatters being called when view is first populated, I expected it to trigger every time the model value changes. Can someone help me understand what's going on? Thank you.
Try using the natural model setter, scope[attrs.ngModel] instead of setviewvalue.
app.directive('format', function($filter) {
return {
require: 'ngModel',
link: function(scope, element, attrs, ctrl) {
element.unbind('input').unbind('keydown').unbind('change');
element.bind('blur', function() {
if (element.val()) {
scope.$apply(function() {
scope[attrs.ngModel] = element.val();
});
}
});
ctrl.$formatters.unshift(function(modelValue) {
if (modelValue) {
var formatted = $filter('currency')(modelValue);
return formatted;
}
});
}
}
});
To ensure this works correctly, a parser will also be necessary.
