OBJECT - Embedded Object. The OBJECT element is used to include objects such as images, audio, videos, Java applets, and Flash animations. OBJECT is intended to replace the more specific IMG and APPLET elements, as well as the proprietary EMBED and BGSOUND elements, though a lack of browser support and severe bugs in supporting browsers make the other elements a better choice in many cases. OBJECT's DATA attribute specifies the URI of the embedded object. 13.1 Introduction to objects, images, and applets. HTML's multimedia features allow. Start tag: required, End. The OBJECT element allows authors to. The PDF Developer Junkie Blog Tips, tricks. Please see The Web Designer’s Guide to Acrobat for an updated article on embedding PDF in HTML. The 'Customizing PDF Portfolio Layouts' Series. Relative URIs are interpreted with respect to the CODEBASE attribute if it is given. The WIDTH and HEIGHT attributes define the dimensions of the object. The value may be given in pixels or as a percentage of the parent element's width or height. Many browsers require the WIDTH and HEIGHT attributes for all objects embedded using OBJECT. The CLASSID attribute may be used to specify an implementation for the object. Java applets, Python applets, and Active. X controls all provide implementations for the embedded object, and so are specified with the CLASSID attribute, as in the following example: < OBJECT CLASSID=. In the example, a Yahtzee game written in Python is used if the browser supports it. A Java version is provided as an alternative for browsers that do not support Python applets. An image is given for browsers that cannot show the Java or Python applets, and text is used as a final alternative if images are not loaded. Note that OBJECT is backwards compatible with pre- HTML 4. OBJECT> tags and render the innermost alternate content (the text in the example). The preceding example also makes use of the TYPE and CODETYPE attributes to allow browsers to avoid requesting a file that they cannot render. The TYPE attribute specifies the media type of the resource referenced by the DATA attribute while the CODETYPE attribute specifies the media type of the CLASSID data. The STANDBY attribute is also utilized in the example. This attribute provides short text to display while the object is loading. The ARCHIVE attribute can specify a space- separated list of archived files (either absolute URIs or URIs relative to the CODEBASE), allowing the browser to download many files with a single connection and hence decreasing the total download time. If the object takes parameters, code them with <param> tags inside the object. HTML object tag, Param properties, embedding media content, movie, audio, mp3, swf flash, pdf files. The HTML Embedded Object Element (object). Embed a flash movie with parameters --> <object data='movie.swf' type='application/x-shockwave-flash'> <param name='foo' value. ![]() The standard archive format for Java files is JAR. JAR files can be created with the jar tool included with the Java Development Kit. The DECLARE attribute makes the object a declaration that is not immediately instantiated. This allows the object to be instantiated from a link, button, or object later in the same document. The ID attribute must be used with declared objects as an identifier for the instantiating element. For example: < OBJECT DECLARE ID=yahtzee CLASSID=. The following example embeds a video, with an audio clip for alternate content, and includes parameters commonly understood by audio/video plug- ins. Note the placement of PARAM elements before alternate content.< OBJECT DATA=. Image maps via the IMG element are better supported, but OBJECT- based image maps allow richer alternatives for browsers not loading images. The USEMAP attribute points to a MAP element whose contents define the links of the various coordinates. The MAP may be included within the OBJECT, in which case its contents are not rendered on image- loading browsers, or it may be given outside the OBJECT element so that its contents are rendered. The following example gives two images, one an alternate if the first type of image is not supported. The images share a single image map definition, which is included within the OBJECT element. The MAP element contains a menu of links to be rendered on browsers not loading images.< OBJECT DATA=. An object with TABINDEX=0 or no TABINDEX attribute will be visited after any elements with a positive TABINDEX. Among positive TABINDEX values, the lower number receives focus first. In the case of a tie, the element appearing first in the HTML document takes precedence. The ALIGN attribute, deprecated in HTML 4, specifies the alignment of the object. The values top, middle, and bottom specify the object's position with respect to surrounding content on its left and right. ALIGN=middle aligns the vertical center of the object with the current baseline. To center the object horizontally on the page, place the object in a centered block, e. P ALIGN=center> < OBJECT DATA=. To place content below the object, use < BR CLEAR=left. Specifying BORDER=0 will eliminate the border around a linked object in most browsers. Authors should only use BORDER=0 if the object would be clearly recognizable as a link, or as a method of de- emphasizing a link. For example: < A HREF=. The value must be in pixels and applies to both sides of the object. Style sheets provide more flexibility in specifying the space around objects. The OBJECT element is most useful as a BODY element and can be contained within either inline or block- level elements. The content of the OBJECT should be elements that can be contained within OBJECT's parent element. For example, an A element containing an OBJECT should not have any block- level elements as the content of the OBJECT. More Information.
