I'm trying to use $setValidity
on an element in a directive. All the examples I've found seem to set it on the controller...
I forked a JS fiddle on Form Validation and have tried a bunch of things. Any insights would be most appreciated: http://jsfiddle.net/thomporter/pmKpG/2/
In the fiddle, the $setValidity
is called on the controller:
ctrl.$setValidity('pwd', true);
I'd like to do something like:
elm.$setValidity('pwd', true);
so that in the form I can do something like:
ng-class="{error:form.password.$error.pwd}"
The $setValidity() function is a built-in AngularJS function that is used to assign a key/value combination that can be used to check the validity of a specific model value. The key in this case is “unique” and the value is either true or false.
The form instance can optionally be published into the scope using the name attribute. So to check form validity, you can check value of $scope. yourformname. $valid property of scope.
AngularJS offers client-side form validation. AngularJS monitors the state of the form and input fields (input, textarea, select), and lets you notify the user about the current state. AngularJS also holds information about whether they have been touched, or modified, or not.
$dirty means the user has changed the input value, $invalid means the address itself is invalid. Therefore the error is only shown if the user has actively changed the input value to either an empty or invalid value.
I figured it out... You have to have a name on the input elements. As soon as I added the name, the errors were automatically bound to the elements as desired, no additional changes needed!
<input ng-model="password"
name="inputPassword"
class="immediate-help"
password-validate
required
type="password"
id="inputPassword"
placeholder="Password">
