Interactive Radio Form For Free

Use the querySelector() method to check whether a radio button is selected. Programmers can use JavaScript's querySelector() method to select any HTML element. Here, we have used the querySelector() method to select only the checked radio button. If no radio button is selected, it returns a null value.

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. Note: The radio group must have share the same name (the value of the name attribute) to be treated as a group.

The radiogroup must have an accessible name either by a visible label referenced by aria-labelledby or has a label specified with aria-label . If elements provide additional information about the radio group, those elements are referenced by the radiogroup element with the aria-describedby property.

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.

The HTML <form> element contains child elements that collect user input, such as <input type=?radio?>. To make a basic form with radio buttons in it, wrap your radio button grouping(s) in a <form> tag, and include a <button> of type submit at the bottom.

To create each radio button option, create a RadioButton in your layout. However, because radio buttons are mutually exclusive, you must group them together inside a RadioGroup . By grouping them together, the system ensures that only one radio button can be selected at a time.

A radio group is defined by giving each of radio buttons in the group the same name . Once a radio group is established, selecting any radio button in that group automatically deselects any currently-selected radio button in the same group.
