HTML 5 <param> Tag

The HTML <param> tag is used for passing parameters to an embedded object.

This tag is used in conjunction with the <object> tag.

To use the <param> tag, you need to nest it inside a <object> element.

Example

Here's an example of <param> usage.

In this example, we are passing two parameters to the embedded object: "autoplay" and "controller". The "autoplay" parameter is set to "false", so the music won't start playing as soon as the page loads. Instead, the user has to press the play button to start the audio. The "controller" attribute is set to "true" and so specifies that the controls applicable to this object (i.e. audio controls) should be visible.

Source Code	Result
<object data="/music/lostmojo.wav"> <param name="autoplay" value="false"> <param name="controller" value="true"> </object>

Attributes

HTML tags can contain one or more attributes. Attributes are added to a tag to provide the browser with more information about how the tag should appear or behave. Attributes consist of a name and a value separated by an equals (=) sign, with the value surrounded by double quotes. Here's an example, style="color:black;".

There are 3 kinds of attributes that you can add to your HTML tags: Element-specific, global, and event handler content attributes.

The attributes that you can add to this tag are listed below.

Element-Specific Attributes

The following table shows the attributes that are specific to this tag/element.

Attribute	Description
name	Defines the name of the parameter. Required attribute.
value	Specifies the value of the parameter. Required attribute.

Global Attributes

The following attributes are standard across all HTML 5 tags.

accesskey	draggable	style
class	hidden	tabindex
contenteditable	id	title
contextmenu	lang
dir	spellcheck

For a full explanation of these attributes, see HTML 5 global attributes.

Event Handler Content 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.

Here are the standard HTML 5 event handler content attributes.

onabort	onerror*	onmousewheel
onblur*	onfocus*	onpause
oncanplay	onformchange	onplay
