Mirror input text.

Update a result as the user types using a jQuery input event.

<body>
<label for="name">Name</label><input id="name"><output id="result"></output>
<script src="jquery.min.js"></script>
<script>
$(function () {
$("#name").on("input", function () { $("#result").text($(this).val()); });
});
</script>
</body>
</html>

Expected output EXAMPLE

Enter “Ada” into the “#name” element.
The “#result” element displays “Ada”.

Details

Save as example.html beside jquery.min.js (jQuery 3.5.1). Open in a browser. The test uses the same local jQuery file as this website, with no CDN or network requests.

Test inputs, results and environment

The exact published code ran in a dedicated Linux test container with prepared inputs. Unprivileged snippet process, external networking disabled, read-only root filesystem, and a fresh temporary working directory. Fixtures and output records are isolated from the application database. Testing covers this example and its stated checks, not every input, operating system, or runtime version. The Linux container shares its host's kernel; this is not a native Windows test.

Test input setup

These are the prepared inputs used by the test harness. See Details above for the prerequisites and how to run this example.

# No input files required.

Observed standard output

Expected output describes the rendered page. The standard-output record below is the browser test harness receipt; the additional assertions check the result and interactions.

Mirror input text: browser checks passed.

Exit code: 0. Standard error: empty. Validation: Shape/content assertions. System-dependent values above are one recorded run.

Additional assertions that passed

Checks recorded by the test harness. Where Python assertions are shown, browser cases use Playwright and simulator cases may inspect pin transitions: result.stdout is captured output, work is the temporary directory, and Path is pathlib.Path. The harness also imports json and csv.

await page.locator('#name').fill('Ada')
assert await page.locator('#result').inner_text() == 'Ada'
