Properties #

accessibleName #

Type: string | null | undefined

String used to label the component to screen reader users.

accessibleNameRef #

Type: string | null | undefined

Id of the element used as label of the component to screen reader users.

allowedCharPattern #

Type: string

A pattern matched against individual characters the user inputs.

When set, the field will prevent:

• keydown events if the entered key doesn't match /^allowedCharPattern$/
• paste events if the pasted text doesn't match /^allowedCharPattern*$/
• drop events if the dropped text doesn't match /^allowedCharPattern*$/

For example, to allow entering only numbers and minus signs, use: allowedCharPattern = "[\\d-]"

autocapitalize #

Type: "characters" | "none" | "off" | "on" | "sentences" | "words"

This is a property supported by Safari and Chrome that is used to control whether autocapitalization should be enabled when the user is entering/editing the text. Possible values are: characters: Characters capitalization. words: Words capitalization. sentences: Sentences capitalization. none: No capitalization.

autocomplete #

Type: string | undefined

Whether the value of the control can be automatically completed by the browser. List of available options at: https://developer.mozilla.org/en/docs/Web/HTML/Element/input#attr-autocomplete

autocorrect #

Type: boolean

This is a property supported by Safari that is used to control whether autocorrection should be enabled when the user is entering/editing the text. Possible values are: on: Enable autocorrection. off: Disable autocorrection.

autofocus #

Type: boolean

Specify that this control should have input focus when the page loads.

autoselect #

Type: boolean

If true, the input text gets fully selected when the field is focused using click or touch / tap.

clearButtonVisible #

Type: boolean

Set to true to display the clear icon which clears the input.

It is up to the component to choose where to place the clear icon: in the Shadow DOM or in the light DOM. In any way, a reference to the clear icon element should be provided via the clearElement getter.

disabled #

Type: boolean

If true, the user cannot interact with this element.

errorMessage #

Type: string | null | undefined

Error to show when the field is invalid.

helperText #

Type: string | null | undefined

String used for the helper text.

invalid #

Type: boolean

Set to true when the field is invalid.

label #

Type: string | null | undefined

The label text for the input node. When no light dom defined via [slot=label], this value will be used.

manualValidation #

Type: boolean

Set to true to enable manual validation mode. This mode disables automatic constraint validation, allowing you to control the validation process yourself. You can still trigger constraint validation manually with the validate() method or use checkValidity() to assess the component's validity without affecting the invalid state. In manual validation mode, you can also manipulate the invalid property directly through your application logic without conflicts with the component's internal validation.

maxlength #

Type: number | null | undefined

Maximum number of characters (in Unicode code points) that the user can enter.

Type: number | null | undefined

Minimum number of characters (in Unicode code points) that the user can enter.

readonly #
