Input Radio Notification For Free

HTML <input type=?radio?> Radio Buttons are used to let the user select exactly one option from a list of predefined options. Radio Button input controls are created by using the ?input? element with a type attribute having the value as ?radio?.

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.

To label a radio button, add a <label> element after the <input> element and insert a for attribute with the same value as the id of the associated <input> element. Then, write your label text in the <label> tag. While using <label> isn't strictly necessary, it's considered a best practice for two reasons.

Definition and Usage. 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.

Radio button allows user to choose only one of the pre-defined options. Each radio button must be accompanied by a label describing the choice it represents. Another alternative is to provide an ID for each radio element and then use that ID in the for attribute of the label.

To define a radio button, we use the <input> element of HTML. When a particular option is selected using a radio button, the other options are deselected i.e., one can only select a single option at a time. It lets the user select from a set of limited options.

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.
