HTML 5 <button> Tag

<!-- Example 1 -->
<button onclick="JavaScript:alert('Well done!')">
	Click Me!
</button>

<!-- Example 2 -->
<button onclick="JavaScript:alert('You will love this book!')">
	<img src="/pix/web_graphics/free_website_graphics/icons/books/book13.gif" alt="Read book">

</button>

The HTML <button> tag is used for creating a button control.

Although this tag is often used in conjunction with the <form> element, it can also be used as a standalone control.

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
autofocus	Automatically gives focus to this control when the page loads. This allows the user to start using the control without having to select it first. There must not be more than one element in the document with the autofocus attribute specified. This is a boolean attribute. If the attribute is present, its value must either be the empty string or a value that is an ASCII case-insensitive match for the attribute's canonical name, with no leading or trailing whitespace (i.e. either `autofocus` or `autofocus="autofocus"`). Possible values: [Empty string] autofocus
disabled	Disables the control. Therefore, if the user tries to use the control, nothing will happen. This is a boolean attribute. If the attribute is present, its value must either be the empty string or a value that is an ASCII case-insensitive match for the attribute's canonical name, with no leading or trailing whitespace (i.e. either `disabled` or `disabled="disabled"`). Possible values: [Empty string] disabled
form	Specifies the ID of a form to which this control belongs. Possible values: [The ID of a form element in the element's owner `Document`]
formaction	Specifies the URL of the file that will process the control when submitted.
formenctype	Specifies the content type used to encode the form data set when it's submitted to the server. Possible values: `application/x-www-form-urlencoded` (default) `multipart/form-data` (use this when uploading files) `text/plain` (use this when uploading files)
formmethod	Specifies the HTTP method to use when the control is submitted. Possible values: `get` (the form data is appended to the URL when submitted) `post` (the form data is not appended to the URL) `dialog` (Closes the dialog box in which the form finds itself, if any, and otherwise does not submit.)
formnovalidate	Specifies that the form is not to be validated during submission. This is a boolean attribute. If the attribute is present, its value must either be the empty string or a value that is an ASCII case-insensitive match for the attribute's canonical name, with no leading or trailing whitespace (i.e. either `novalidate` or `novalidate="novalidate"`). Possible values: [Empty string] novalidate
formtarget	Specifies the browsing context to load the destination indicated in the `action` attribute. Possible values: `_blank` `_self` `_top` `_parent`
menu	If the `type` attribute has a value of `menu`, the `menu` attribute must be provided in order to specify the element's menu. The value must be the ID of a `<menu>` element in the same home subtree whose `type` attribute is in the popup menu state. The `menu` attribute can only be used when the `type` attribute has a value of `menu`.
name	Assigns the name of the control.
type	Specifies the type of button. Possible values: `submit` Submits the form. This is the default value. `reset` Resets the form. `button` Does nothing. You can use JavaScript to make the control actually do something. `menu` Displays a menu. When using this value, you must specify the menu using the `menu` attribute (see above).
value	Assigns an initial value to the control. A button (and its value) is only included in the form submission if the button itself was used to initiate the form submission.
