Can You Tab Through All Radio Buttons

Can you tab through all radio buttons?

You can cite the W3C as your source, here and here.

Essentially a radio button is a group that functions as a single element since it retains only a single value. Tabbing to a radio group will bring you to the first item and then using the arrow keys you navigate within the group.

• Focus can move to a radio group via:
  • The Tab key
    
  • An Access Key or mnemonic targeting the label
  • 
    Activation of the label (through Assistive Technology mechanism)
    
• The Tab key moves focus between radio button
  groups and other widgets.
• When focus is on the group and
  when no radio button is selected:
  • Tab key press moves focus
    to the first radio button in the group, but does not select the radio
    button.
  • Shift+Tab key press moves focus to the last radio
    button in the group, but does not select the radio button.
• When focus moves to the group in which a radio button is
  selected, pressing Tab and Shift+Tab keys move focus to the radio
  button that is checked.
• Up Arrow and Down Arrow keys move
  focus and selection.
  • Up Arrow key press moves focus and
    selection forward through the radio buttons in the group. If the first
    radio button has focus, then focus and selection move to the last
    radio button in the group.
  • Down Arrow key press moves focus
    and selection backward through the radio buttons in the group. If the
    last radio button has focus, then focus and selection move to the
    first radio button in the group. * Space Bar key press checks the
    radio button that currently has focus.
• When
  re-entering the group, focus returns to the point of previous focus
  (the item with selection set).
• Pressing the Tab key exits
  the group and moves focus to the next form control.
• Pressing
  the Shift+Tab keys exits the group and moves focus to the previous
  form control.

Tab through radiobuttons

when the radiobuttons are focused you can select another by using the arrow-keys

or
try something like:

$('input[name="something"]').on("keypress", function(e) {
    if(e.keyCode == '9')
        $(this).next().focus().attr("checked", true)
});

hope this works & helps ;-)

Tabbing to All Radio Buttons in a Group Box

When using a radio button group, you can tab to the group, and then use the arrow keys to navigate to next and previous. As far as I am aware, that is the expected behaviour.

This looks like an old article, but they mention here the use of arrow keys in a group

Again, an old article here, but accessibility hasn't changed around this.

Radio buttons are used in sets, identified by their sharing the same
name attribute value. This implies some differences in their treatment
by browsers. Consider the following example, where the three buttons
all belong to the same group, i.e. have the same name attribute:

On IE, when a radio button group is reached via tabbing, the initially
selected button is focused on, and the dotted rectangle indicates
this. You can use arrow keys to move between the buttons inside the
group; both "down" and "right" arrow move forward inside the group,
and both "up" and "left" arrow move backward. And upon moving to a
button, that button gets checked (and the button in the group that was
checked gets unchecked).

Tab selection ignores all elements generated within loop in React

Just add a name to your inputs.

<input name={"gender-" + gender} type="radio" value={gender} />

Full example:

const App = () => {
  const genders = ["male", "female", "netural"];
  return (
    <React.Fragment>
      <h1>Hello Example</h1>
      <div>
        <p>
          Same name (and same group, only 1 selected) - select first element with TAB and use arrows up and down
          keys to navigate
        </p>
        {genders.map((gender) => (
          <div key={gender}>
            <div>
              <input name={"gender"} type="radio" value={gender} />
              {gender}
            </div>
          </div>
        ))}
      </div>
      <br />
      <div>
        <p>Different names (and group - you can select all of them) - use tab key to navigate</p>
        {genders.map((gender) => (
          <div key={gender}>
            <div>
              <input name={"gender" + gender} type="radio" value={gender} />
              {gender}
            </div>
          </div>
        ))}
      </div>
    </React.Fragment>
  );
};

ReactDOM.render(
    <App />,
    document.getElementById("root")
);
