Hey guys, today in this post we are going to learn about LWC how to get selected radio button value on handle-change function and displaying content of radio button checked value Using ‘lightning-radio-group’ element in Lightning Web Component (LWC).

A lightning-radio-group component represents a group of radio buttons that permit only one button to be selected at a time. The component renders radio button input elements and assigns the same value to the name attribute for each element. The common name attribute joins the elements in a group. If you select any radio button in that group, any previously selected button in the group is deselected.

In general, we don’t recommend setting the name attribute in lightning-radio-group. The component automatically generates a unique value for name if none is provided. The generated value ensures a common name for the input elements rendered for the radio button group, and is unique in the page.

See Reusing lightning-radio-group in a Page for name attribute considerations if you want to use the component multiple times in a page.

If the required attribute is specified, at least one radio button must be selected. When a user interacts with the radio button group and doesn’t make a selection, an error message is displayed.

If the disabled attribute is specified, radio button selections can’t be changed. To learn more Click Here.
