HTML <output> Tag
<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.
<output> tag is written as
</output> with any contents inserted between the start and end tags.
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.
form attribute can be specified to associate the
<output> element to its form owner.
name attribute can also be used to provide a name for the element.
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 can be added to an HTML element to provide more information about how the element should appear or behave.
<output> element accepts the following attributes.
|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.|
|Associates the output with a form.|
|Specifies the name of this element.|
The following attributes are standard across all HTML elements. Therefore, you can use these attributes with the
<output> tag , as well as with all other HTML tags.
For a full explanation of these attributes, see HTML 5 global attributes.
Event handler content attributes enable you to invoke a script from within your HTML. The script is invoked when a certain "event" occurs. Each event handler content attribute deals with a different event.
Most event handler content attributes can be used on all HTML elements, but some event handlers have specific rules around when they can be used and which elements they are applicable to.
For more detail, see HTML event handler content attributes.
