Ability to Focus on a
Using JavaScript's focus() Function

Original Question:

Is it feasible to focus on a

element by utilizing JavaScript's focus() function?

Additional Details:

I aim to target the following

element using focus():

<code class="html"><div id="tries">You have 3 tries left</div></code>

However, invoking document.getElementById('tries').focus(); fails to accomplish this task. Can anyone provide guidance on resolving this issue?

Answer:

By assigning a tabindex attribute, you can attain the desired focus on a

tag.

Implementation:

<code class="html"><div tabindex="0">Hello World</div></code>

Setting tabindex to 0 integrates the tag into the page's inherent tab order, with 0 representing the first element in the sequence. Higher values indicate an order of precedence, wherein 1 is prioritized over 2 and so forth.

Alternatively, you can assign a tabindex of -1 to limit focus-ability to scripts, rendering the element inaccessible to user interaction.

Example:

<code class="javascript">document.getElementById('test').onclick = function () {
    document.getElementById('scripted').focus();
};</code>

<code class="css">div:focus {
    background-color: Aqua;
}</code>

<code class="html"><div>Element X (not focusable)</div>
<div tabindex="0">Element Y (user or script focusable)</div>
<div tabindex="-1" id="scripted">Element Z (script-only focusable)</div>
<div id="test">Set Focus To Element Z</div></code>

By incorporating these techniques, you can deftly manipulate the focus of your desired

elements, enabling seamless control over user interactions and accessibility.
