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) | How to display selected radio button value in lwc

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.
