| Attribute | Description |

| disabled | The disabled attribute is used to disable the button so that it cannot be activated. HTML <button> example using a disabled submit button. <form action="example_input.php" method="post">
<p>
Text: <input type="text" name="texttest" title="test"><br>
<button type="submit" name="submit" value="submit" disabled="disabled">Send</button>
<button type="reset" name="reset"><img src="yel.gif" alt="reset"><br>Reset</button>
</p>
</form>XHTML <button> example using a disabled submit button. <form action="example_input.php" method="post">
<p>
Text: <input type="text" name="texttest" title="test" /><br />
<button type="submit" name="submit" value="submit" disabled="disabled">Send</button>
<button type="reset" name="reset"><img src="yel.gif" alt="reset" /><br />Reset</button>
</p>
</form> |
| name | The name attribute assigns a name to the control. The name is paired with the value and submitted with the form. HTML submit button with the name and value attributes. <form action="example_input.php" method="post"> <p> Text: <input type="text" name="texttest" title="test"><br> <button type="submit" name="submit" value="send_it">send_it</button> </p> </form> XHTML submit button with the name and value attributes. <form action="example_input.php" method="post"> <p> Text: <input type="text" name="texttest" title="test" /><br /> <button type="submit" name="submit" value="send_it">send_it</button> </p> </form> |
| value | The value attribute assigns a value to the control. The name is paired with the value and submitted with the form. Note: Some browsers may use the contents of the button element instead of the value attribute. Therefore, consider setting the button element content and the value attribute to the same value to increase browser compatibility. HTML submit button with the name and value attributes. <form action="example_input.php" method="post">
<p>
Text: <input type="text" name="texttest" title="test"><br>
<button type="submit" name="submit" value="send_it">send_it</button>
</p>
</form>XHTML submit button with the name and value attributes. <form action="example_input.php" method="post">
<p>
Text: <input type="text" name="texttest" title="test" /><br />
<button type="submit" name="submit" value="send_it">send_it</button>
</p>
</form> |
| type | The type attribute specifies the type of button. Possible values are button, submit, and reset. The button type creates a button that does not submit a value with the form but instead it can be used with a scripting language, like Javascript, to give it functionality. The submit type creates a button that is used to submit the form. The reset type creates a button that resets all of the controls, in the current form, to their initial values. HTML & XHTML <button> example using button type with JavaScript. <p>
<button type="button" onclick="window.location='http://www.littlewebhut.com'">
Go To Little Web Hut</button>

| id | The id attribute assigns a unique name to a tag. This allows style sheets or scripts to reference the tag. See id Example |
| class | The class attribute assigns a class name to a tag. The class name does not need to be unique. More than one tag can have the same class name. This allows style sheets or scripts to reference multiple tags with a single class name. See class Example |
| style | The style attribute specifies styles for the tag. For Cascading Style Sheets (CSS), the syntax is name:value. Each name:value pair is separated by semicolons. See style Example |
| title | The title attribute specifies additional information about the tag. It is common for browsers to display the title when the pointing device stops over the object. See title Example |
| accesskey | The accesskey specifies a shortcut key for a tag. The action that is taken when an access key is invoked depends on the tag and may also depend on the browser. For example, if it is used with an <a> tag, some browsers may follow the link when the access key is invoked and other browsers may give focus to the link. See accesskey Example |
| onblur | The onblur attribute specifies a script to be run when the tag loses focus. See onblur Example |
| onfocus | The onfocus attribute specifies a script to be run when the tag receives focus. See onfocus Example |
| tabindex | The tabindex attribute specifies the tabbing position of the tag. The tabbing sequence runs from lower values to higher values. The valid range of values is between 0 and 32767. See tabindex Example |
| onclick | The onclick attribute specifies a script to be run when the object is clicked with a mouse or other pointing device. See onclick Example |
| ondblclick | The ondblclick attribute specifies a script to be run when the object is double clicked with a mouse or other pointing device. See ondblclick Example |
| onkeydown | The onkeydown attribute specifies a script to be run when a key is pressed down. See onkeydown Example |
| onkeypress | The onkeypress attribute specifies a script to be run when a key is pressed and released. See onkeypress Example |
| onkeyup | The onkeyup attribute specifies a script to be run when a key is released. See onkeyup Example |
| onmousedown | The onmousedown attribute specifies a script to be run when the mouse button, or other pointing device button, is pressed while over the object. See onmousedown Example |
| onmousemove | The onmousemove attribute specifies a script to be run when the mouse, or other pointing device, is moved while it is over the object. See onmousemove Example |
| onmouseout | The onmouseout attribute specifies a script to be run when the mouse, or other pointing device, is moved away from an object after being over it. See onmouseout Example |
| onmouseover | The onmouseover attribute specifies a script to be run when the mouse, or other pointing device, is moved onto the object. See onmouseover Example |
| onmouseup | The onmouseup attribute specifies a script to be run when the mouse button, or other pointing device button, is released while over the object. See onmouseup Example |
| dir | The dir attribute tells the browser whether the text should be displayed from left-to-right or right-to-left. It does not reverse the direction of the characters, like the <bdo> tag does, but it can help the browser to determine if the text should be aligned on the left side or the right side. See dir Example |
| lang | The lang attribute specifies a language. This attribute can help the browser to correctly display text. This attribute can also be useful for braille translation software, speech synthesizers, dictionary definitions, etc. See lang Example |
| xml:lang | The xml:lang attribute specifies a language for XHTML documents. This attribute can help the browser to correctly display text. This attribute can also be useful for braille translation software, speech synthesizers, dictionary definitions, etc. See xml:lang Example Note: XHTML only. |
