Attributes
This element includes the global attributes.
for
- A list of IDs of other elements, indicating that those elements contributed input values to (or otherwise affected) the calculation.
form
- The form element that this element is associated with (its "form owner"). The value of the attribute must be an ID of a form element in the same document. If this attribute is not specified, the output element must be a descendant of a form element. This attribute enables you to place output elements anywhere within a document, not just as descendants of their form elements.
name
- The name of the element.
Example
<form oninput="result.value=parseInt(a.value)+parseInt(b.value)"> <input type="range" name="b" value="50" /> + <input type="number" name="a" value="10" /> = <output name="result">60</output> </form>
