HTML native button Enter Space keydown preventDefault suppress click activation browser behavior specification

💡 Result:

According to the HTML specification and established browser behavior, native HTML buttons (the element) possess a built-in activation behavior that triggers a click event when the button is activated via the keyboard [1][2]. Specifically, the specification dictates that when a user triggers an element with a defined activation behavior (like a button) via keyboard input, the default action of that interaction must be to fire a click event at the element [1]. For native buttons, this activation occurs as follows: - Enter key: Triggers the click event on the keydown phase [3]. - Space key: Triggers the click event on the keyup phase [3][4]. Because the browser's activation of the button is a default action associated with these key events, calling event.preventDefault on the corresponding keydown or keyup event will suppress that default behavior and prevent the subsequent click event from firing [5][6]. Practical implications include: - Suppression Strategy: If you need to intercept a key press (e.g., to perform a custom action or prevent a side effect) without triggering the button's native click handler, calling preventDefault within the appropriate event handler (keydown for Enter, keyup for Space) is the standard method to achieve this [7][6]. - Browser/Screen Reader Variability: While the core specification is consistent, the interplay between browser implementations and assistive technology can vary [3]. Some screen readers intercept keyboard events before they reach the browser's DOM event loop, which may lead to inconsistencies in whether or not your preventDefault logic is respected [3]. - Development Best Practice: Relying on native elements and allowing their default keyboard behavior is generally recommended for accessibility [8]. If you are creating a custom component that mimics a button (e.g., a

with role="button"), you are responsible for manually implementing this keyboard activation logic, which often involves listening for Enter/Space on keydown and triggering a click [8].

native HTML button Space keydown preventDefault click fires on keyup Enter keydown keyboard activation

💡 Result:

Native HTML buttons (the

element) handle keyboard activation differently for the Enter and Space keys to simulate physical button behavior [1][2][3]. When a native has focus: 1. Enter key: The click event is fired on keydown [1][3]. 2. Space key: The click event is fired on keyup [1][3]. The Space key's default behavior includes scrolling the page, which is why developers often use event.preventDefault during the keydown event to suppress this side effect [4][5]. However, because the native button's click action for Space is tied to the keyup event, calling preventDefault on the keydown event does not prevent the click event from firing on keyup [6][7]. If you are implementing a custom button (e.g., using a
or with role="button") and wish to mimic this behavior, you must manually manage the click dispatch [5][8]. A common approach for custom buttons is: 1. Listen for keydown. 2. Check if the key is Enter or Space. 3. Call preventDefault to stop unwanted browser behaviors (like page scrolling for Space) [4][5]. 4. Manually trigger the button's action (e.g., calling.click or your custom function) [5]. Note that because browsers differ in how they handle these events, standard practice is to use native
elements whenever possible to ensure consistent, accessible keyboard interaction without manual event handling [8][9].

Handle Space activation only once.

A native button fires click on Enter keydown and Space keyup. preventDefault() on keydown does not cancel the Space click, so this handler toggles openInfo twice for one Space press. Remove custom Enter/Space handling and keep onClick; retain custom handling only for Escape. Add tests for one state transition per key.

Externalize the accessible label.

aria-label="Repository health metrics information" is user-visible text for screen readers. Store it in the i18n resources and read it through the existing translation helper.

As per path instructions: User-visible strings should be externalized to resource files (i18n).

WAI-ARIA APG modal dialog pattern aria-modal focus moves into dialog focus remains within dialog official

💡 Result:

According to the W3C WAI-ARIA Authoring Practices Guide (APG), the modal dialog pattern requires strict focus management to ensure accessibility, as the aria-modal="true" attribute does not provide this functionality automatically [1]. Developers must implement the following behaviors using JavaScript: 1. Moving Focus into the Dialog: When a modal dialog opens, keyboard focus must be moved to an element within the dialog [2][3][4]. Generally, focus is initially placed on the first focusable element, though for large content, placing focus on a static element (e.g., the dialog title or a container with tabindex="-1") is recommended to ensure the user perceives the dialog content correctly [2][3]. 2. Containing Focus (Focus Trap): Focus must remain within the dialog until it is closed [2][4]. The tab sequence is "contained," meaning that pressing Tab or Shift + Tab must not move focus outside the dialog window [2][3]. If focus reaches the last focusable element and the user presses Tab, it must cycle back to the first focusable element; similarly, if focus is on the first element and the user presses Shift + Tab, it must cycle back to the last element [3][5]. 3. Returning Focus: When the dialog is closed, focus must be returned to the element that originally triggered the dialog [2][6][4]. The aria-modal="true" attribute informs assistive technologies that the content outside the dialog is inert [2][1]. However, it is the developer's responsibility to ensure that the application code prevents all users from interacting with content outside the dialog and that the background is visually obscured [1][7]. Failure to maintain the focus trap or to return focus correctly significantly impacts the experience for keyboard and screen reader users [4].

Align aria-modal with focus behavior.

If this popup is modal, move focus into it, trap Tab and Shift+Tab, and restore focus to #info-button on every close path. The popup has no focusable descendant, and click-outside closing does not restore focus. Otherwise, remove aria-modal="true" and treat the popup as non-modal.

🧰 Tools
🪛 React Doctor (0.9.3)

[warning] 132-132: Keyboard users can tab out of this role="dialog" modal because it has no built-in focus trapping, so use the native <dialog>, which gives you focus trapping, Escape to close, and the backdrop for free.

Replace the wrapper with <dialog> and open it with dialog.showModal(). For the trigger, prefer <button commandfor="id" command="show-modal"> (Chrome 135+), or a useRef with dialogRef.current?.showModal().
