Utilizing Ng-Required for Angular Form Validation

FIDDLE HERE: http://jsfiddle.net/TegFf/48/

Within my form, there are radio buttons (you can view them in the Fiddle link above) that need to validate the following scenarios:

  1. The user must select a radio button with a corresponding dollar amount
  2. If "custom" is selected, a value must be entered as well

I'm encountering an issue where the Ng-Required attribute placed on an input field is not correctly determining if it should be required or not.

<input name="donation" type="radio" value="yes" ng-model="manual" required="false">
<input type="number" ng-model="donation" ng-required="manual === 'yes'">

Answer №1

http://jsfiddle.net/TegFf/49/

Here are a few points to note:

  • The first radio input has a unique name attribute.
  • Putting the manual amount inside a label with the radio button will prevent you from being able to focus on the field.
  • In an AngularJS form, all fields must be valid for the form to be considered valid. To troubleshoot, consider adding debug code to identify any invalid fields.

Answer №2

Please remember to include 'name="donation"' in your first radio button. Additionally, be cautious as setting the variable manual to 'yes' will keep it that way permanently. Consider streamlining your variables or implementing a customized validation through a directive.
