HTML <output> Tag

What is HTML <output> Tag?

The HTML output tag is used to display the result of a calculation or user action performed by a script or form. It represents the outcome of an operation, such as mathematical computation or dynamic input value changes.

This tag is mainly used with form elements like input, select, and textarea. It helps show live or calculated results directly on the webpage without refreshing. The output tag improves user interaction and creates dynamic web pages that respond to user input in real time.

Syntax of the HTML <output> Tag

plaintext
<output name="result">Displayed Result</output>

The name attribute identifies the output element so it can be accessed or updated using JavaScript. The displayed text between the tags represents the initial output before any calculation or update occurs.

Examples of HTML <output> Tag

Example 1: Basic HTML Output Tag

plaintext
<!DOCTYPE html>
<html lang="en">
<body>

<form oninput="sum.value=parseInt(a.value)+parseInt(b.value)">
  <input type="number" name="a" value="10"> +
  <input type="number" name="b" value="20"> =
  <output name="sum"></output>
</form>

</body>
</html>

In this example, two number input fields are added. When a user types new values, the sum is automatically calculated and displayed inside the output tag.

Example 2: Practical Example Using Scholar247

plaintext
<!DOCTYPE html>
<html lang="en">
<body>

<h3>Scholar247 Marks Calculator</h3>

<form oninput="total.value=parseInt(english.value)+parseInt(math.value)">
  English Marks: <input type="number" id="english" name="english" value="70"> +
  Math Marks: <input type="number" id="math" name="math" value="80"> =
  <output name="total" for="english math"></output>
</form>

</body>
</html>

This example uses the HTML output tag to create a simple calculator. When users input marks for English and Math, the total appears instantly within the output tag. It provides an interactive experience, suitable for education sites like Scholar247.
