What is this?

text() reads and writes plain text (HTML is escaped). html() reads and writes markup. Prefer text() for anything that might include user or API strings.

Why should you care?

Flash messages and labels are daily QueryVerse work — picking text vs html is an XSS decision, not just formatting.

See it live — copy this example

Examples include the jQuery 3.7 CDN. Paste into an HTML file or use Run Example to preview.

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <title>QueryVerse</title>
  <style>
    body { font-family: system-ui, sans-serif; margin: 1.25rem; }
    .box { padding: .75rem; border: 1px solid #ccc; border-radius: 8px; margin: .5rem 0; }
    .muted { color: #666; }
    button { margin-right: .35rem; margin-top: .35rem; }
    input, select, textarea { margin: .25rem 0; }
    table { border-collapse: collapse; width: 100%; }
    th, td { border: 1px solid #ddd; padding: .4rem .55rem; text-align: left; }
    .hidden { display: none; }
    .row-odd { background: #f7f7f7; }
    .active { font-weight: 700; }
    .toast { background: #111; color: #fff; padding: .5rem .75rem; border-radius: 6px; }
  </style>
</head>
<body>
  <div id="panel" class="box">Old</div>
  <button type="button" id="asText">Set text</button>
  <button type="button" id="asHtml">Set html</button>
<script src="https://code.jquery.com/jquery-3.7.1.min.js"></script>
<script>
$(function () {
  $('#asText').on('click', function () {
    $('#panel').text('<b>safe</b> plain');
  });
  $('#asHtml').on('click', function () {
    $('#panel').html('<b>bold</b> markup');
  });
});
</script>
</body>

What happened?

  • text escapes angle brackets.
  • html parses tags.
  • Never pipe unsanitized user input into html().
  • Function forms .text(fn) / .html(fn) receive the old value.

Practice next

  1. Click both buttons and compare the panel.
  2. Read back with .text() and .html() in the console.
  3. Try .text(function(i, old){ return old + "!"; }).
  4. Build a trusted badge with html then fill the name with text on a child.
  5. Use .empty() before text for a clean slate.

Remember

text = escaped string. html = parsed markup. Untrusted data → text.

Server flash banner

QueryVerse shows a Razor TempData message on a Policybazaar-like agent desk.

Outcome: You choose text for the message body and avoid XSS from odd quotes.
