dbcInput: Input component

In plotly/dashR: An Interface to the Dash Ecosystem for Authoring Reactive Web Applications

Input component

Description

A basic HTML input control for entering text, numbers, or passwords, with Bootstrap styles automatically applied. This component is much like its counterpart in dash_core_components, but with a few additions such as the 'valid' and 'invalid' props for providing user feedback. Note that checkbox and radio types are supported through the Checklist and RadioItems component. Dates, times, and file uploads are supported through separate components in other libraries.

Arguments

id	Character. The ID of this component, used to identify dash components in callbacks. The ID needs to be unique across all of the components in an app.
style	Named list. Defines CSS styles which will override styles previously set.
class_name	Character. Often used with CSS to style elements with common properties.
className	Character. **DEPRECATED** Use 'class_name' instead. Often used with CSS to style elements with common properties.
key	Character. A unique identifier for the component, used to improve performance by React.js while rendering components See https://reactjs.org/docs/lists-and-keys.html for more info
type	A value equal to: "text", 'number', 'password', 'email', 'range', 'search', 'tel', 'url', 'hidden'. The type of control to render
value	Character | numeric. The value of the Input
disabled	Logical. Set to True to disable the Input.
autocomplete	Character. This attribute indicates whether the value of the control can be automatically completed by the browser.
autoComplete	Character. **DEPRECATED** Use 'autocomplete' instead. This attribute indicates whether the value of the control can be automatically completed by the browser.
autofocus	A value equal to: 'autofocus', 'autofocus', 'autofocus' | logical. The element should be automatically focused after the page loaded. autoFocus is an HTML boolean attribute - it is enabled by a boolean or 'autoFocus'. Alternative capitalizations 'autofocus' & 'AUTOFOCUS' are also acccepted.
autoFocus	A value equal to: 'autofocus', 'autofocus', 'autofocus' | logical. **DEPRECATED** Use 'autofocus' instead. The element should be automatically focused after the page loaded. autoFocus is an HTML boolean attribute - it is enabled by a boolean or 'autoFocus'. Alternative capitalizations 'autofocus' & 'AUTOFOCUS' are also acccepted.
inputmode	A value equal to: "verbatim", "latin", "latin-name", "latin-prose", "full-width-latin", "kana", "katakana", "numeric", "tel", "email", "url". Provides a hint to the browser as to the type of data that might be entered by the user while editing the element or its contents.
inputMode	A value equal to: "verbatim", "latin", "latin-name", "latin-prose", "full-width-latin", "kana", "katakana", "numeric", "tel", "email", "url". **DEPRECATED** Use 'inputmode' instead. Provides a hint to the browser as to the type of data that might be entered by the user while editing the element or its contents.
list	Character. 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	Character | numeric. The maximum (numeric or date-time) value for this item, which must not be less than its minimum (min attribute) value.
maxlength	Character | numeric. If the value of the type attribute is text, email, search, password, tel, or url, this attribute specifies the maximum number of characters (in UTF-16 code units) that the user can enter. For other control types, it is ignored. It can exceed the value of the size attribute. If it is not specified, the user can enter an unlimited number of characters. Specifying a negative number results in the default behavior (i.e. the user can enter an unlimited number of characters). The constraint is evaluated only when the value of the attribute has been changed.
maxLength	Character | numeric. **DEPRECATED** Use 'maxlength' instead. If the value of the type attribute is text, email, search, password, tel, or url, this attribute specifies the maximum number of characters (in UTF-16 code units) that the user can enter. For other control types, it is ignored. It can exceed the value of the size attribute. If it is not specified, the user can enter an unlimited number of characters. Specifying a negative number results in the default behavior (i.e. the user can enter an unlimited number of characters). The constraint is evaluated only when the value of the attribute has been changed.
min	Character | numeric. The minimum (numeric or date-time) value for this item, which must not be greater than its maximum (max attribute) value.
minlength	Character | numeric. If the value of the type attribute is text, email, search, password, tel, or url, this attribute specifies the minimum number of characters (in Unicode code points) that the user can enter. For other control types, it is ignored.
minLength	Character | numeric. **DEPRECATED** Use 'minlength' instead. If the value of the type attribute is text, email, search, password, tel, or url, this attribute specifies the minimum number of characters (in Unicode code points) that the user can enter. For other control types, it is ignored.
step	Character | numeric. Works with the min and max attributes 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 attribute is not set to any, the control accepts only values at multiples of the step value greater than the minimum.
html_size	Character. The initial size of the control. This value is in pixels unless the value of the type attribute is text or password, in which case it is an integer number of characters. This attribute applies only when the type attribute is set to text, search, tel, url, email, or password, otherwise it is ignored. In addition, the size must be greater than zero. If you do not specify a size, a default value of 20 is used.
size	Character. Set the size of the Input. Options: 'sm' (small), 'md' (medium) or 'lg' (large). Default is 'md'.
valid	Logical. Apply valid style to the Input for feedback purposes. This will cause any FormFeedback in the enclosing div with valid=True to display.
invalid	Logical. Apply invalid style to the Input for feedback purposes. This will cause any FormFeedback in the enclosing div with valid=False to display.
required	A value equal to: 'required', 'required' | logical. This attribute specifies that the user must fill in a value before submitting a form. It cannot be used when the type attribute is hidden, image, or a button type (submit, reset, or button). The :optional and :required CSS pseudo-classes will be applied to the field as appropriate. required is an HTML boolean attribute - it is enabled by a boolean or 'required'. Alternative capitalizations 'REQUIRED' are also acccepted.
plaintext	Logical. Set to true for a readonly input styled as plain text with the default form field styling removed and the correct margins and padding preserved.
placeholder	Character | numeric. A hint to the user of what can be entered in the control . The placeholder text must not contain carriage returns or line-feeds. Note: Do not use the placeholder attribute instead of a <label> element, their purposes are different. The <label> attribute describes the role of the form element (i.e. it indicates what kind of information is expected), and the placeholder attribute is a hint about the format that the content should take. There are cases in which the placeholder attribute is never displayed to the user, so the form must be understandable without it.
name	Character. The name of the control, which is submitted with the form data.
pattern	Character. 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, email, or password, otherwise it is ignored. The regular expression language is the same as JavaScript RegExp algorithm, with the 'u' parameter that makes it treat the pattern as a sequence of unicode code points. The pattern is not surrounded by forward slashes.
n_submit	Numeric. Number of times the 'Enter' key was pressed while the input had focus.
n_submit_timestamp	Numeric. Last time that 'Enter' was pressed.
n_blur	Numeric. Number of times the input lost focus.
n_blur_timestamp	Numeric. Last time the input lost focus.
debounce	Logical. If true, changes to input will be sent back to the Dash server only when the enter key is pressed or when the component loses focus. If it's false, it will sent the value back on every change.
loading_state	Lists containing elements 'is_loading', 'prop_name', 'component_name'. those elements have the following types: - is_loading (logical; optional): determines if the component is loading or not - prop_name (character; optional): holds which property is loading - component_name (character; optional): holds the name of the component that is loading. Object that holds the loading state object coming from dash-renderer
persistence	Logical | character | numeric. Used to allow user interactions in this component to be persisted when the component - or the page - is refreshed. If 'persisted' is truthy and hasn't changed from its previous value, a 'value' that the user has changed while using the app will keep that change, as long as the new 'value' also matches what was given originally. Used in conjunction with 'persistence_type'.
persisted_props	List of a value equal to: 'value's. Properties whose user interactions will persist after refreshing the component or the page. Since only 'value' is allowed this prop can normally be ignored.
persistence_type	A value equal to: 'local', 'session', 'memory'. Where persisted user changes will be stored: memory: only kept in memory, reset on page refresh. local: window.localStorage, data is kept after the browser quit. session: window.sessionStorage, data is cleared once the browser quit.
tabindex	Character. Overrides the browser's default tab order and follows the one specified instead.
tabIndex	Character. **DEPRECATED** Use 'tabindex' instead. Overrides the browser's default tab order and follows the one specified instead.
