button ( type=reset ) element
If you don’t know what an element is or how you must use it, I recommend you read the «HTML tags and attributes» tutorial that you can find in the HTML tutorials section.
Description
The button element, having the «reset» value in its type attribute, represents a button that, when pressed, resets all the fields in the form it belongs to, to their initial values. The label of a button is represented by the content of the element.
In contrast with the input (type=reset) element, this type of button can contain other non-interactive elements.
The way of setting an initial value for a control varies from type to type. In general, the value attribute is the responsible for setting the initial value, but in some cases, the checked or selected attributes may take its place.
Examples
In this example we’ll set up a form with a number of fields of different types, each of which has an initial value. Additionally a reset button will be provided to check its functionality.
Now we’ll see the special feature of the button element, which lets it hold other non-interactive elements. This is one of the main differences it has with the intput (type=reset) element.
Attributes
Specific attributes
autofocus
A boolean value instructing the browser to set the focus to this control when the document has finished loading or when the dialog where the control finds itself is shown. If the attribute has the value «autofocus» or the empty string («»), or if it’s just present, the control should get the focus as soon as possible, after the page or dialog has been loaded.
disabled
A boolean value indicating wether the control is disabled or not. If the attribute takes the value «disabled» or the empty string («»), or if it’s just present, the control will be disabled.
Disabled controls are rendered greyed out (if visible), are blocked from user interaction and, more importantly, their values (if any) aren’t sent when the form is submitted.
The value of the id attribute of the form with which this control is associated to.
A name for the control. This name will be sent by the browser to the processing agent, paired with the content of the value attribute. Both attributes together will conform a name-value pair that will be used to process the form data.
The name-value pair of a button is submitted, with the other form data, only if the button has been used to submit the form.
A value indicating the expected behavior of the button. There are four possible values (case-insensitive) that will decide the default action carried out by the button when it’s pressed:
When this attribute isn’t present, the button behaves as a «submit» button.
value
A value for the control. This value will be sent by the browser to the processing agent, paired with the content of the name attribute. Both attributes together will conform a name-value pair that will be used to process the form data.
The name-value pair of a button is submitted, with the other form data, only if the button has been used to submit the form.
Global attributes

Reset button что это
elements of type reset are rendered as buttons, with a default click event handler that resets all of the inputs in the form to their initial values.
Note: You should usually avoid including reset buttons in your forms. They’re rarely useful, and are instead more likely to frustrate users who click them by mistake (often while trying to click the submit button).
| Value | A DOMString used as the button’s label |
| Events | click |
| Supported common attributes | type and value |
| IDL attributes | value |
| Methods | None |
Value
An element’s value attribute contains a DOMString that is used as the button’s label. Buttons such as reset don’t have a value otherwise.
Setting the value attribute
Omitting the value attribute
Using reset buttons
A simple reset button
We’ll begin by creating a simple reset button:
This renders like so:
Try entering some text into the text field, and then pressing the reset button.
Adding a reset keyboard shortcut
To add a keyboard shortcut to a reset button — just as you would with any for which it makes sense — you use the accesskey global attribute.
In this example, r is specified as the access key (you’ll need to press r plus the particular modifier keys for your browser/OS combination; see accesskey for a useful list of those).
The problem with the above example is that there’s no way for the user to know what the access key is! This is especially true since the modifiers are typically non-standard to avoid conflicts. When building a site, be sure to provide this information in a way that doesn’t interfere with the site design (for example by providing an easily accessible link that points to information on what the site access keys are). Adding a tooltip to the button (using the title attribute) can also help, although it’s not a complete solution for accessibility purposes.
Disabling and enabling a reset button
To disable a reset button, specify the disabled global attribute on it, like so:
Note: See the page for more ideas about enabling and disabling buttons.
Validation
Buttons don’t participate in constraint validation; they have no real value to be constrained.
Examples
We’ve included simple examples above. There isn’t really anything more to say about reset buttons.
