Properties

Наследует свойства своего родителя, HTMLElement.

Название	Тип	Описание
`accept`	`DOMString`	Reflects the `accept` HTML attribute, containing comma-separated list of file types accepted by the server when `type` is `file`.
`accessKey`	`DOMString`	A single character that switches input focus to the control.
`align`	`DOMString`	Alignment of the element.
`alt`	`DOMString`	Reflects the `alt` HTML attribute, containing alternative text to use when `type` is `image.`
`autocapitalize`	`DOMString`	Defines capitalization behavior for user input. Valid values are `none`, `off`, `characters`, `words`, or `sentences`.
`autocomplete`	`DOMString`	Reflects the `autocomplete` HTML attribute, indicating whether the value of the control can be automatically completed by the browser. Ignored if the value of the `type` attribute is hidden, checkbox, radio, file, or a button type (button, submit, reset, image). Possible values are: off: The user must explicitly enter a value into this field for every use, or the document provides its own auto-completion method; the browser does not automatically complete the entry. on: Браузер может автоматически подставить значение основываясь на том, что ранее пользователь вводил в данном в предыдущий раз
`autofocus`	`Boolean`	Reflects the `autofocus` HTML 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).
`checked`	`Boolean`	The current state of the element when `type` is `checkbox` or `radio`.
`defaultChecked`	`Boolean`	The default state of a radio button or checkbox as originally specified in HTML that created this object.
`defaultValue`	`DOMString`	The default value as originally specified in HTML that created this object.
`dirName`
`disabled`	`Boolean`	Reflects the `disabled` HTML attribute, indicating that the control is not available for interaction. The input values will not be submitted with the form. See also `readonly`
`files` Только для чтения	`FileList`	A list of selected files.
`form` Только для чтения	`HTMLFormElement`	The containing form element, if this element is in a form. If this element is not contained in a form element: HTML5 this can be the `id` attribute of any `<form>` element in the same document. Even if the attribute is set on `<input>`, this property will be `null`, if it isn't the id of a `<form>` element. HTML 4 this must be `null`.
`formAction`	`DOMString`	Reflects the `formaction` HTML attribute, containing the URI of a program that processes information submitted by the element. If specified, this attribute overrides the `action` attribute of the `<form>` element that owns this element.
`formEncType`	`DOMString`	Reflects the `formenctype` HTML attribute, containing the type of content that is used to submit the form to the server. If specified, this attribute overrides the `enctype` attribute of the `<form>` element that owns this element.
`formMethod`	`DOMString`	Reflects the `formmethod` HTML attribute, containing the HTTP method that the browser uses to submit the form. If specified, this attribute overrides the `method` attribute of the `<form>` element that owns this element.
`formNoValidate`	`Boolean`	Reflects the `formnovalidate` HTML attribute, indicating that the form is not to be validated when it is submitted. If specified, this attribute overrides the `novalidate` attribute of the `<form>` element that owns this element.
`formTarget`	`DOMString`	Reflects the `formtarget` HTML attribute, containing a name or keyword indicating where to display the response that is received after submitting the form. If specified, this attribute overrides the `target` attribute of the `<form>` element that owns this element.

`list`	`HTMLElement`	Identifies a list of pre-defined options to suggest to the user. The value must be the id of a `<datalist>` element in the same document. The browser displays only options that are valid values for this input element. This attribute is ignored when the `type` attribute's value is hidden, checkbox, radio, file, or a button type.
`max`	`DOMString`	Reflects the `max` HTML attribute, containing the maximum (numeric or date-time) value for this item, which must not be less than its minimum (min attribute) value.
`maxLength`	`long`	Reflects the `maxlength` HTML attribute, containing the maximum length of text (in Unicode code points) that the value can be changed to. The constraint is evaluated only when the value is changed Note: If you set `maxLength` to a negative value programmatically, an exception will be thrown.
`min`	`DOMString`	Reflects the `min` HTML attribute, containing the minimum (numeric or date-time) value for this item, which must not be greater than its maximum (`max` attribute) value.
`multiple`		Reflects the `multiple` HTML attribute, indicating whether more than one value is possible (e.g., multiple files).
`name`	`DOMString`	Reflects the `name` HTML attribute, containing a name that identifies the element when submitting the form.
`pattern`	`DOMString`	Reflects the `pattern` HTML attribute, containing a regular expression that the control's value is checked against. The pattern must match the entire value, not just some subset. Use the `title` attribute to describe the pattern to help the user. This attribute applies when the value of the `type` attribute is text, search, tel, url or email; otherwise it is ignored.
`placeholder`	`DOMString`	Reflects the `placeholder` HTML attribute, containing a hint to the user of what can be entered in the control. The placeholder text must not contain carriage returns or line-feeds. This attribute applies when the value of the `type` attribute is text, search, tel, url or email; otherwise it is ignored.
`readOnly`	`Boolean`	Reflects the `readonly` HTML attribute, indicating that the user cannot modify the value of the control. HTML5This is ignored if the value of the `type` attribute is hidden, range, color, checkbox, radio, file, or a button type.
`required`	`Boolean`	Reflects the `required` HTML attribute, indicating that the user must fill in a value before submitting a form.
`selectionDirection`	`DOMString`	The direction in which selection occurred. This is `"forward"` if selection was performed in the start-to-end direction of the current locale, or `"backward"` for the opposite direction. This can also be `"none"` if the direction is unknown."
`selectionEnd`	`unsigned long`	The index of the end of selected text.
`selectionStart`	`unsigned long`	The index of the beginning of selected text. When nothing is selected, this is also the caret position inside of the `<input>` element.
`size`	`unsigned long`	Reflects the `size` HTML attribute, containing size of the control. This value is in pixels unless the value of `type` is text or password, in which case, it is an integer number of characters. HTML5 Applies only when `type` is set to text, search, tel, url, email, or password; otherwise it is ignored.
`src`	`DOMString`	Reflects the `src` HTML attribute, which specifies a URI for the location of an image to display on the graphical submit button, if the value of `type` is image; otherwise it is ignored.
`step`	`DOMString`	Reflects the `step` HTML attribute, which works with `min` and `max` to limit the increments at which a numeric or date-time value can be set. It can be the string any or a positive floating point number. If this is not set to any, the control accepts only values at multiples of the step value greater than the minimum.
`tabIndex`	long	The position of the element in the tabbing navigation order for the current document.
`type`	`DOMString`	Reflects the `type` HTML attribute, indicating the type of control to display. See `type` attribute of `<input>` for possible values.
`useMap`	`DOMString`	A client-side image map.
`validationMessage` Только для чтения	`DOMString`	A localized message that describes the validation constraints that the control does not satisfy (if any). This is the empty string if the control is not a candidate for constraint validation (`willvalidate` is `false`), or it satisfies its constraints.
`validity` Только для чтения	`ValidityState`	The validity state that this element is in.
`value`	`DOMString`	Current value in the control. Note: for certain input types the returned value might not match the value the user has entered. For example, if the user enters a non-numeric value into an <input type="number">, the returned value might be an empty string instead.
`valueAsDate`	`Date`	The value of the element, interpreted as a date, or `null` if conversion is not possible.
`valueAsNumber`	`double`	The value of the element, interpreted as one of the following in order: a time value a number `NaN` if conversion is not possible
`width`	`DOMString`	Reflects the `width` HTML attribute, which defines the width of the image displayed for the button, if the value of `type` is image.
`willValidate`	`Boolean`	Indicates whether the element is a candidate for constraint validation. It is `false` if any conditions bar it from constraint validation.

Methods

Inherits methods from its parent, HTMLElement.

Name & Arguments	Return	Description
`blur()`	`void`	Removes focus from input; keystrokes will subsequently go nowhere.
`checkValidity`()	`Boolean`	Returns 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.
`click()`	`void`	Simulates a click on the element.
`focus()`	`void`	Focus on input; keystrokes will subsequently go to this element.
`mozSetFileArray(files)`	`void`	Sets the files selected on the input to the given array of `File` objects. This is an alternative to `mozSetFileNameArray` which can be used in frame scripts: a chrome script can open files as `File` objects and send them via message manager.
`mozGetFileNameArray(length, filenames)`	`void`	Returns an array of all the file names from the input.
`mozSetFileNameArray(filenames, length)`	`void`	Sets the filenames for the files selected on the input. Not for use in frame scripts, because it accesses the filesystem.
`select()`	`void`	Selects the input text in the element, and focuses it so the user can subsequently replace the whole entry.
`setCustomValidity(error)`	`void`	Sets a custom validity message for the element. If this message is not the empty string, then the element is suffering from a custom validity error, and does not validate.
`setSelectionRange(selectionStart, selectionEnd, [optional] selectionDirection)`	`void`	Selects a range of text in the element (but does not focus it). The optional `selectionDirection` parameter may be `"forward"` or `"backward"` to establish the direction in which selection was set, or `"none"` if the direction is unknown or not relevant. The default is `"none"`. Specifying a `selectionDirection` parameter sets the value of the `selectionDirection` property.
`setRangeText(replacement, [optional] start, [optional] end, [optional] selectMode)`	`void`	Replaces a range of text with the new text. Supported input types: `text`, `search`, `url`, `tel`, `password.`
`stepDown(n)`	`void`	Decrements the `value` by (`step` * `n`), where `n` defaults to `1` if not specified. Throws an `INVALID_STATE_ERR` exception: if the method is not applicable to for the current `type` value. if the element has no `step` value. if the `value` cannot be converted to a number. if the resulting value is above the `max` or below the `min`.
`stepUp(n)`	`void`	Increments the `value` by (`step` * `n`), where `n` defaults to `1` if not specified. Throws an `INVALID_STATE_ERR` exception: if the method is not applicable to for the current `type` value. if the element has no `step` value. if the `value` cannot be converted to a number. if the resulting value is above the `max` or below the `min`.
