Frequently Asked Questions (FAQs):

The following FAQs cover common jQuery radio button group operations:

• Getting the selected radio button's value: Use $('input[name="radioName"]:checked').val(); Replace "radioName" with your actual radio button group name.

• Setting a radio button's value: Use $('input[name="radioName"]').prop('checked', true); to select a specific radio button.

• Checking if a radio button is selected: Use $('input[name="radioName"]:checked').length > 0 to check if any radio button within the group is selected.

• Handling radio button change events: Use $('input[name="radioName"]').change(function() { /* your code here */ }); to execute code when a selection changes.

• Disabling/Enabling radio buttons: Use .prop('disabled', true) to disable and .prop('disabled', false) to enable.

• Toggling a radio button's state: Use $('input[name="radioName"]').prop('checked', !$('input[name="radioName"]').prop('checked')); to switch the selection state.

• Getting the selected radio button's text: This requires additional HTML structure (e.g., a label next to each radio button). A solution might involve using .next().text() to get the text of the sibling element following the selected radio button.

• Getting the selected radio button's ID or name: Use .attr('id') or .attr('name') respectively, combined with the :checked selector.
