An invalid form control with name='' is not focusable on hidden element

All we need is an easy explanation of the problem, so here it is.

I have an element that conditionally appears that is required to be filled out when visible. (using ng-required)

However, when it is not visible, I’m getting the following error:

An invalid form control with name=” is not focusable

How do I force ng-required to work ONLY if it element is visible. I do not want to enter novalidate in the form, because if I do, when the element is visible, the validation does not occur.

How to solve :

I know you bored from this bug, So we are here to help you! Take a deep breath and look at the explanation of your problem. We have many solutions to this problem, But we recommend you to use the first method because it is tested & true method that will 100% work for you.

Method 1

Like this, using a boolean for both ng-show and ng-required:

<form>
  <input type="text" ng-show="displayCondition" ng-required="displayCondition"/>
</form>

Good question – a lot of people do not realize that passing false into ng-required disables the directive.

Method 2

I solved it very easy with using ng-if instead of ng-show! Us only ng-if. When it is not visible the element is not in the code anymore. So the browser will not validate it.

Note: Use and implement method 1 because this method fully tested our system.
Thank you 🙂
