Angular 1.5 觸發表單驗證

常用的方法，簡單的表單驗證由控制器觸發

//submit後觸發驗證

$scope.validateByManual = function(form) {

logger.debug('validate');

angular.forEach(form, function (control, name) {

// Excludes internal angular properties

if (typeof name === 'string' && name.charAt(0) !== '$') {

logger.debug('field name:' + name);

// To display ngMessages

control.$setTouched();

control.$setDirty();

// Runs each of the registered validators

control.$validate();

}

});

}
