To set a radio button to checked/unchecked, select the element and set its checked property to true or false , e.g. myRadio. checked = true . When set to true , the radio button becomes checked and all other radio buttons with the same name attribute become unchecked.

Add Radio Buttons Dynamically In order to create a radio button, we need to define the input element and assign it to a variable called input. Then, change its input type to radio. Finally, append the input element to the label element.

If you want to assign a checked initial value to your radio button, you can use the HTML checked attribute. In the example below, we use a <form> tag and add <div> elements within it.

In case we need to select a radio button by default, we need to check it as true. Whenever the radio buttons are checked as true, then it will be autofocused by default.

const yesBtn = document. getElementById('yes'); // ✅ Set radio button to checked yesBtn. checked = true; // ✅ Set radio button to unchecked yesBtn.

Radio buttons allow the user to select one option from a set. You should use radio buttons for optional sets that are mutually exclusive if you think that the user needs to see all available options side-by-side. If it's not necessary to show all options side-by-side, use a spinner instead.

This process can be automated by looping through an array that contains all the possible values and creating a new radio button element for each item in the array. To dynamically create radio button using an array, use the concept of createElement() and appendChild().
