HTML <output> Tag
The HTML <output>
tag represents the result of a calculation or user action. This could include displaying the results of a calculation performed by a script, or it could display the output of a user's interaction with a form element.
Syntax
The <output>
tag is written as <output>
</output>
with any contents inserted between the start and end tags.
The for
attribute can be used to specify an explicit relationship to be made between the result of a calculation and the elements that represent the values that went into the calculation or that otherwise influenced the calculation.
The form
attribute can be specified to associate the <output>
element to its form owner.
The name
attribute can also be used to provide a name for the element.
Like this:
Example
This example uses the <output>
tag to display the result of an interest rate calculation, based on user input. The <output>
element is also used to display the result of the range slider as the user adjusts the interest rate.
Attributes
Attributes can be added to an HTML element to provide more information about how the element should appear or behave.
The <output>
element accepts the following attributes.
Attribute | Description |
---|---|
for | Allows an explicit relationship to be made between the result of a calculation and the elements that represent the values that went into the calculation or that otherwise influenced the calculation. The value must be a list of IDs (separated by a space) of elements within the same document. |
form | Associates the output with a form. |
name | Specifies the name of this element. |
