autofocus |
Boolean : Returns / Sets the element's autofocus attribute, which specifies that a form control should have input focus when the page loads, unless the user overrides it, for example by typing in a different control. Only one form element in a document can have the autofocus attribute. It cannot be applied if the type attribute is set to hidden (that is, you cannot automatically set focus to a hidden control). |

Methods
blur() |
Removes focus from the input element; keystrokes will subsequently go nowhere. |
click() |
Simulates a click on the input element. |
focus() |
Focuses on the input element; keystrokes will subsequently go to this element. |
select() |
Selects all the text in the input element, and focuses it so the user can subsequently replace all of its content. |

Selects a range of text in the input element (but does not focus it). |
setRangeText() |
Replaces a range of text in the input element with new text. |
setCustomValidity() |

checkValidity() |
Returns a Boolean that is false if the element is a candidate for constraint validation, and it does not satisfy its constraints. In this case, it also fires an invalid event at the element. It returns true if the element is not a candidate for constraint validation, or if it satisfies its constraints. |
reportValidity() |
Runs the checkValidity() method, and if it returns false (for an invalid input or no pattern attribute provided), then it reports to the user that the input is invalid in the same manner as if you submitted a form. |
HTMLInputElement.stepDown()
- Decrements the
value
by (step
* n), where n defaults to 1 if not specified. Throws an INVALID_STATE_ERR exception: HTMLInputElement.stepUp()
- Increments the
value
by (step
* n), where n defaults to 1 if not specified. Throws an INVALID_STATE_ERR exception: HTMLInputElement.mozGetFileNameArray()
- Returns an array of all the file names from the input.
HTMLInputElement.mozSetFileNameArray()
- Sets the filenames for the files selected on the input.
Events
Listen to these events using addEventListener()
or by assigning an event listener to the oneventname
property of this interface:
input
- Fires when the
value
of an<input>
,<select>
, or<textarea>
element has been changed. Note that this is actually fired on theHTMLElement
interface and also applies tocontenteditable
elements, but we've listed it here because it is most commonly used with form input elements.
Also available via theoninput
event handler property. invalid
- Fired when an element does not satisfy its constraints during constraint validation.
Also available via theoninvalid
event handler property. search
- Fired when a search is initiated on an
<input>

Also available via theonsearch
event handler property.
