In this video we will discuss working with radio buttons in Angular Template Driven forms.


We want to include "Gender" radio buttons in the Create Employee form as shown below. When we select employee "Gender" using the radio buttons, the selected gender value should reflect in the Angular generated form model as shown in the image below. Also, we we click the "Save" button we want the selected gender value to be logged to the console.

To achieve this all you have to do is include the following HTML in create-employee.component.html file

<div class="form-group">
  <label>Gender</label>
  <div class="form-control">
    <label class="radio-inline">
      <input type="radio" name="gender" value="male" [(ngModel)]="gender">
      Male
    </label>
    <label class="radio-inline">
      <input type="radio" name="gender" value="female" [(ngModel)]="gender">
      Female
    </label>
  </div>
</div>

Code Explanation
  • The name attribute is required to group the radio buttons as one unit and make the selection mutually exclusive. Make sure both the radio buttons have the same value for the "name" attribute. Otherwise the radio button selection won't be mutually exclusive.
  • It is also important that you set the "value" attribute for each radio button. This value is posted to the server when the form is submitted.
While we are here, let's also include a textbox to capture "Phone Number" and "Contact Preference" radio button. So the form should now look as as shown below.
