How can I make a clickable <div> easily navigable with tab functionality?

Question

How can I make a clickable <div> easily navigable with tab functionality?

I am currently tackling a project that involves implementing an onclick event within a <div>. While I've successfully set up the primary functionality, there is one issue at hand. Specifically, I need the onclick event to trigger when a user navigates to the <div> by tabbing and then hits the enter key. Although I have added a tabindex to the <div> so it can receive focus, nothing occurs when the user presses enter or any other key.

Is there anyone who could offer me some guidance on this matter? Or is what I'm seeking simply not feasible?

You can view a demonstration of my conundrum on jsfiddle: http://jsfiddle.net/logiwan992/suwq7r09/

I greatly appreciate any assistance provided in advance.

Answer №1

Upon reviewing the question, I see that it is categorized under WCAG and "accessibility".

In response to your query, I advise against the current approach. The solutions provided by others on this page may work well for most users, but they may not be suitable for individuals relying on screen readers or other assistive technologies. None of the javascript-based methods mentioned here comply with WCAG standards.

The ideal solution is to utilize a <button> element, as it inherently provides tabindex and keyboard functionality.

If necessary, you can modify a <div> to function like a button by incorporating ARIA attributes (although utilizing the appropriate tag is recommended for simplicity).

For further guidance on implementing ARIA for pseudo-buttons, refer to: https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/ARIA_Techniques/Using_the_button_role

To summarize, remember to include the role="button" attribute and manage the aria-pressed attribute manually to create a pseudo-button (detailed explanations on this process are available in other responses).

Using a <div> as a button is acceptable as long as you correctly specify the necessary ARIA tags, roles, and keyboard events. This is the essence of ARIA's functionality.

It is generally recommended to utilize standard HTML elements whenever possible, as outlined in the guidelines for ARIA use at http://www.w3.org/TR/aria-in-html/#notes-on-aria-use-in-html. However, there may be situations where this is not feasible.

The mention of using focus() is inaccurate. The focus() function is intended to shift focus to an object rather than handling an event. It might have been referring to onFocus(), an event triggered when an object gains focus, but this is still not the suitable event to capture. A button (whether implemented as a <div> or a <button>) should only execute its function when clicked or activated with enter/space.

Refer to the authoring practices that outline keyboard behavior for buttons at http://www.w3.org/TR/wai-aria-practices/#button, as well as the section discussing keyboard events at http://www.w3.org/TR/wai-aria-practices/#focus_tabindex. Avoid relying on keypress as it is not uniformly supported across all browsers.

When interacting with keys, remember that three potential events may occur: Keydown, keypress, and keyup. Keydown and keyup are consistent across browsers and provide access to event.keyCode, while keypress is not universally supported and offers event.charCode instead.

Understanding the distinction between keyCode and charCode is crucial, particularly for implementing shortcut keys like Ctrl+/. Different keyboards may produce varying keyCodes for special keys, which can complicate implementation and require additional considerations.

Answer №3

To detect if the Enter key (with code number 13) was pressed on a specific div, you can bind the keypress event to that div.

var div = document.getElementsByTagName('div');
div[0].addEventListener('keypress', function(e) {
    if(e.keyCode == 13) {
        alert('Enter key pressed on div');   
    }
});

See it in action on JSFiddle

If you prefer jQuery, you can achieve the same functionality like this:

jQuery(function($) {

    $('div').on('keypress', function(e) {
        if(e.keyCode == 13) {
            alert('Enter key pressed on div'); 
        }
    });

});

When it comes to links, the "onclick" attribute behaves in a specific way as it can also be activated by pressing the enter key.

To avoid WCAG failure, refer to the following link for more information: http://www.w3.org/TR/WCAG20-TECHS/F59.html

It is crucial to consider the designated "role" of each element.

If you want to create an accessible link using a "span" element, check out this page: https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/ARIA_Techniques/Using_the_link_role

Remember, whenever possible, use a button or an anchor element for the best user experience.

Answer №5

To enable focus on an element, assign the attributes role="button" and tabindex="0". Then, detect when the enter or space key is pressed while any button is focused/active and convert it into a click event.

Here is the HTML and jQuery code to achieve this functionality. Simply add this code once and it will work for all elements with role=button.

<div role="button" tabindex="0">Do that thing</div>

$("body").on("keypress","[role='button']", function(e) { 
     if(e.keyCode == 13 || e.keyCode == 32){ // 13=enter, 32=spacebar
         $(this).click();
         return false;
     }
})

I opt for this method over using a proper <button> element as it avoids complications related to overriding browser button styles. This approach is commonly used in interfaces like Gmail, where numerous clickable icons, settings, and navigation buttons exist without a single <button> element in sight.

Answer №6

Utilize a single event handler for both occurrences. Check if the event is a keypress and ensure that the Enter key was pressed before proceeding with execution.

var buttonElement = document.querySelector('#button-element');

buttonElement.addEventListener('click', handleClick);
buttonElement.addEventListener('keypress', handleClick);

function handleClick(event) {
  if (event.type === 'keypress' && event.keyCode == 13) {
    alert('Button activated successfully'); 
  }
};

div {
    outline: 1px solid black;
}

div:focus {
    outline: 1px solid red;
}

<div id="button-element" tabindex="0">
    <h1>Click me!</h1>
</div>
