The element used for embedding multimedia
and applications in HTML is called. It replaces older tags such asand.lets us include objects such as images, video, flash, sounds, and
applications into a webpage. To include an object we have two attributes
to specify its location. Data is used when we want to embed data that the browser can
display by itself – such as a document or an image. Classid on the other hand is needed
if our object needs to execute an external program – such as a media player, active-x
control, or Java applet. The type attribute is used in combination
with the data attribute to identify the data file type. Codetype is used together with
the classid to identify the content type of the expected data. If codetype is omitted
it will use the type attribute instead. The codebase attribute provides an alternative
base URL from which the browser will retrieve the object. The value of this attribute is
an link pointing to a directory containing the object referenced by the classid attribute.
The standby attribute can be used to display a message while the browser is downloading
the object data. Some other elements are available that we
might recognize from the image tag. Most importantly, the height and width attributes which control
the size of the object. The param tags are used as input parameters
to objects. This tag may only appear inside anelement and has no content or
end tag. It required two attributes: either name or id, and value. Together, they define
a name/value pair that is passed to the object. As an example, to include a image in a document,
