Properties

Name Description Reflects Type Default
accesskey Accesskey provides a hint for generating a keyboard shortcut for the current element. The attribute value must consist of a single printable character. string -
align Used by Et2Box to determine alignment. Allowed values are left, right string -
autocapitalize Controls whether and how text input is automatically capitalized as it is entered by the user. 'off' | 'none' | 'on' | 'sentences' | 'words' | 'characters' -
autocomplete Specifies what permission the browser has to provide assistance in filling out form field values. Refer to this page on MDN for available values. string -
autocorrect Indicates whether the browser’s autocorrect feature is on or off. string -
autofocus Have browser focus this input on load. Overrides etemplate2.focusOnFirstInput(), use only once per page https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input#attributes boolean -
class CSS Class. This class is applied to the outside, on the web component itself. Due to how WebComponents work, this might not change anything inside the component. string -
data Set the dataset from a CSV string -
defaultValue
The default value of the form control. Primarily used for resetting the form control. string ''
deferredProperties
Any attribute that refers to row content cannot be resolved immediately, but some like booleans cannot stay a string because it’s a boolean attribute. We store them for later, and parse when they’re fully in their row. If you are creating a widget that can go in a nextmatch row, and it has boolean attributes that can change for each row, add those attributes into deferredProperties - -
disabled Defines whether this widget is visibly disabled. The widget is still visible, but clearly cannot be interacted with. Widgets disabled in the template will not return a value to the application code, even if re-enabled via javascript before submitting. To allow a disabled widget to be re-enabled and return a value, disable via javascript in the app’s et2_ready() instead of an attribute in the template file. boolean false
dom_id
Get the actual DOM ID, which has been prefixed to make sure it’s unique. string -
enterkeyhint Used to customize the label or icon of the Enter key on virtual keyboards. 'enter' | 'done' | 'go' | 'next' | 'previous' | 'search' | 'send' -
filled Draws a filled textarea. boolean false
form By default, form controls are associated with the nearest containing <form> element. This attribute allows you to place the form control outside of a form and associate it with the form that has this id. The form must be in the same document or shadow root for this to work. string ''
hasFeedbackFor
Get a list of feedback types string[] -
height Specify the height of the text area. If not set, it will expand to fill the space available. string -
helpText The textarea’s help text. If you need to display HTML, use the help-text slot instead. string ''
hidden The widget is not visible. As far as the user is concerned, the widget does not exist. Widgets hidden with an attribute in the template may not be created in the DOM, and will not return a value. Widgets can be hidden after creation, and they may return a value if hidden this way. boolean -
id
Get the ID of the widget string -
inputmode Tells the browser what type of data will be entered by the user, allowing it to display the appropriate virtual keyboard on supportive devices. 'none' | 'text' | 'decimal' | 'numeric' | 'tel' | 'search' | 'email' | 'url' -
label The label of the widget Legacy support for labels with %s that get wrapped around the widget Not the best way go with webComponents - shouldn’t modify their DOM like this string -
maxlength The maximum length of input that will be considered valid. number -
minlength The minimum length of input that will be considered valid. number -
name The name of the textarea, submitted as a name/value pair with form data. string ''
noLang Disable any translations for the widget boolean -
parentId Parent is different than what is specified in the template / hierarchy. Widget ID of another node to insert this node into instead of the normal location string -
placeholder Placeholder text to show as a hint when the input is empty. string ''

translate
List of properties that get translated Done separately to not interfere with properties - if we re-define label property, labels go missing. - -
validationMessage
Gets the validation message - -
validity
Gets the validity state object - -
value The current value of the textarea, submitted as a name/value pair with form data. string ''
width Use width and height attributes to affect style It would be better to deprecate these and just use CSS string -

Compatibility for deprecated name “needed”
use required instead

Methods

Name Description Arguments
blur() Removes focus from the textarea. -
checkCreateNamespace() Checks whether a namespace exists for this element in the content array. If yes, an own perspective of the content array is created. If not, the parent content manager is used. Constructor attributes are passed in case a child needs to make decisions -
checkValidity() Checks for validity but does not show a validation message. Returns true when valid and false when invalid. -
clone() Creates a copy of this widget. _parent: et2_widget
createElementFromNode() Create a et2_widget from an XML node. First the type and attributes are read from the node. Then the readonly & modifications arrays are checked for changes specific to the loaded data. Then the appropriate constructor is called. After the constructor returns, the widget has a chance to further initialize itself from the XML node when the widget’s loadFromXML() method is called with the node. _node: , _name:
et2HandleBlur() If the value is unchanged, put any held validation messages back Named et2HandleBlur to avoid overwriting handleBlur() in Shoelace components _ev: FocusEvent
et2HandleFocus() When input receives focus, clear any validation errors. If the value is the same on blur, we’ll put them back The ones from the server (ManualMessage) can interfere with submitting. Named et2HandleFocus to avoid overwriting handleFocus() in Shoelace components _ev: FocusEvent
focus() Sets focus on the textarea. options: FocusOptions
getArrayMgr() Returns the array manager object for the given part managed_array_type: string
getArrayMgrs() Returns an associative array containing the top-most array managers. _mgrs: object
getChildren() Get child widgets Use .children to get web component children -
getForm() Gets the associated form, if one exists. -
getInputNode() Get input to e.g. set aria-attributes -
getInstanceManager() Returns the instance manager -
getPath() Returns the path into the data array. By default, array manager takes care of this, but some extensions need to override this -
getRoot() Returns the base widget Usually this is the same as getInstanceManager().widgetContainer -
isValid() Used by etemplate2 to determine if we can submit or not messages:
loadFromXML() Loads the widget tree from an XML node _node:
loadingFinished() Needed for legacy compatability. promises: Promise[]
parseXMLAttrs() The parseXMLAttrs function takes an XML DOM attributes object and adds the given attributes to the _target associative array. This function also parses the legacyOptions. N.B. This is only used for legacy widgets. WebComponents use transformAttributes() and do their own handling of attributes. _attrsObj: , _target: object, _proto: et2_widget
reportValidity() Checks for validity and shows the browser’s validation message if the control is invalid. -
scrollPosition() Gets or sets the textarea’s scroll position. position: { top?: number; left?: number }
select() Selects all the text in the textarea. -
set_label() NOT the setter, since we cannot add to the DOM before connectedCallback() TODO: This is not best practice. Should just set property, DOM modification should be done in render https://lit-element.polymer-project.org/guide/templates#design-a-performant-template value: string
setArrayMgr() Sets the array manager for the given part _part: string, _mgr: object
setArrayMgrs() Sets all array manager objects - this function can be used to set the root array managers of the container object. _mgrs: object
setCustomValidity() Sets a custom validation message. Pass an empty string to restore validity. message: string
setInstanceManager() Set the instance manager Normally this is not needed as it’s set on the top-level container, and we just return that reference manager: etemplate2
setRangeText() Replaces a range of text with a new string. replacement: string, start: number, end: number, selectMode: 'select' | 'start' | 'end' | 'preserve'
setSelectionRange() Sets the start and end positions of the text selection (0-based). selectionStart: number, selectionEnd: number, selectionDirection: 'forward' | 'backward' | 'none'
setTextareaMaxHeight() Override some parent stuff to get sizing how we like it * -
submit() Called whenever the template gets submitted. We return false if the widget is not valid, which cancels the submission. _values:
updated() A property has changed, and we want to make adjustments to other things based on that changedProperties: PropertyValues
validate() Massively simplified validate, as compared to what ValidatorMixin gives us, since ValidatorMixin extends FormControlMixin which breaks SlSelect’s render() We take all validators for the widget, and if there’s a value (or field is required) we check the value with each validator. For array values we check each element with each validator. If the value does not pass the validator, we collect the message and display feedback to the user. We handle validation errors from the server with ManualMessages, which always “fail”. If the value is empty, we only validate if the field is required. skipManual:
_handleClick() Click handler calling custom handler set via onclick attribute to this.onclick _ev: MouseEvent
_labelTemplate() Common sub-template to add a label. This goes inside the form control wrapper div, before and at the same depth as the input controls. -
_oldChange() Change handler calling custom handler set via onchange attribute _ev: Event
_set_label() Do some fancy stuff on the label, splitting it up if there’s a %s in it Normally called from updated(), the “normal” setter stuff has already been run before this is called. We only override our special cases (%s) because the normal label has been set by the parent value: string
_setAriaAttributes() Set aria-attributes on our input node -
destroy() et2_widget compatability
true
-
set_class() Set the widget class
Use this.class or this.classList instead
new_class: string
set_disabled() Wrapper on this.disabled because legacy had it.
Use widget.disabled for visually disabled, widget.hidden for visually hidden. Widgets that are hidden from the server via attribute or $readonlys will not be created. Widgets that are disabled from the server will not return a value to the application code.
value: boolean
set_statustext() supports legacy set_statustext
use this.statustext
value: string
