A radio button in an html document has a tagname input and it has a type attribute set to radio. We can select a radio button by using the click() method after identifying it. Let us see the html code of a radio button. To identify it with a value attribute we have to use the xpath or css locator.

This is how we are able to set the default checked value of a radio button: We initialize the state variable to the value of the specific radio button. We set the checked prop on each radio button to conditionally check whether the state variable is equal to its value.

Change the value of the value attribute of a radio button: document. ... Using radio buttons together with a text input field to display the value of the selected radio button: document.

The <input type="radio"> defines a radio button. Radio buttons are normally presented in radio groups (a collection of radio buttons describing a set of related options). Only one radio button in a group can be selected at the same time.

Solution with the checked attribute 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.

You group radio buttons by drawing them inside a container such as a Panel control, a GroupBox control, or a form. All radio buttons that are added directly to a form become one group. To add separate groups, you must place them inside panels or group boxes.

To get the value of the selected radio button, a user-defined function can be created that gets all the radio buttons with the name attribute and finds the radio button selected using the checked property. The checked property returns True if the radio button is selected and False otherwise.
