When working with AngularJS, dynamically checking a radio button involves manipulating the ng-model directive bound to the radio button input element. Here's a step-by-step guide to achieve this:

Set Up Your HTML Template

First, define your radio button inputs in your HTML template. Each radio button should have its own ng-model directive, which will bind the selected value to a scope variable in your AngularJS controller.

Define Your AngularJS Controller

Next, define your AngularJS controller and initialize the scope variables. In this example, we'll have an array of options and a variable to hold the selected option.

Dynamically Check Radio Buttons

To dynamically check a radio button, simply update the value of the selectedOption scope variable in your controller. AngularJS will handle the binding and update the UI accordingly.

Usage in HTML Template

You can trigger the selectOption function when needed, such as in response to a user action or some other event in your application.

By calling selectOption('option2'), the radio button with the value 'option2' will be dynamically checked.

By following these steps, you can dynamically check radio buttons in your AngularJS application based on your requirements.
