InputMaskDateTime

A class that describes an input mask of the "datetime" maskType.

The following code shows how to specify the properties of this class within a survey JSON schema:

const surveyJson = {
  "elements": [{
    "name": "textquestion1"
    "type": "text",
    "maskType": "datetime",
    "maskSettings": {
      // Specify the properties of a date-time input mask here
    }
  }]
}

clone method

Creates a new object that has the same type and properties as the current SurveyJS object.

Type:: () => Base

Implemented in:: Base

fromJSON method

Assigns a new configuration to the current SurveyJS object. This configuration is taken from a passed JSON object.

The JSON object should contain only serializable properties of this SurveyJS object. Event handlers and properties that do not belong to the SurveyJS object are ignored.

Type:: (json: any, options?: ILoadFromJSONOptions) => void

Parameters:: json, type: any ,
A JSON object with properties that you want to apply to the current SurveyJS object.

options, type: ILoadFromJSONOptions ,
An object with configuration options.

Implemented in:: Base

See also:: toJSON

getPropertyByName method

Returns a JsonObjectProperty object with metadata about a serializable property that belongs to the current SurveyJS object.

If the property is not found, this method returns null.

Type:: (propName: string) => JsonObjectProperty

Parameters:: propName, type: string ,
A property name.

Implemented in:: Base

getPropertyValue method

Returns the value of a property with a specified name.

If the property is not found or does not have a value, this method returns either undefined, defaultValue specified in the property configuration, or a value passed as the defaultValue parameter.

Type:: (name: string, defaultValue?: any, calcFunc?: () => any) => any

Parameters:: name, type: string ,
A property name.

defaultValue, type: any ,
(Optional) A value to return if the property is not found or does not have a value.

calcFunc, type: () => any

Implemented in:: Base

getType method

Returns the object type as it is used in the JSON schema.

Type:: () => string

Implemented in:: Base

inSurvey property

Returns true if the object is included in a survey.

This property may return false, for example, when you create a survey model dynamically.

Type:: boolean readonly

Implemented in:: Base

isDescendantOf method

Use this method to find out if the current object is of a given typeName or inherited from it.

Type:: (typeName: string) => boolean

Parameters:: typeName, type: string ,
One of the values listed in the getType() description.

Return Value:: true if the current object is of a given typeName or inherited from it.

Implemented in:: Base

See also:: getType

isDesignMode property

Returns true if the survey is being designed in Survey Creator.

Type:: boolean readonly

Implemented in:: Base

isLoadingFromJson property

Returns true if the object configuration is being loaded from JSON.

Type:: boolean readonly

Implemented in:: Base

isValueEmpty method

Returns true if a passed value is an empty string, array, or object or if it equals to undefined or null.

Type:: (value: any, trimString?: boolean) => boolean

Parameters:: value, type: any ,
A value to be checked.

trimString, type: boolean ,
(Optional) When this parameter is true, the method ignores whitespace characters at the beginning and end of a string value. Pass false to disable this functionality.

Implemented in:: Base

max property

A maximum date and time value that respondents can enter.

Type:: string readonly

This property is stored in the survey JSON definition and can be edited in the Survey Creator.

Implemented in:: InputMaskDateTime

See also:: min

min property

A minimum date and time value that respondents can enter.

Type:: string readonly

This property is stored in the survey JSON definition and can be edited in the Survey Creator.

Implemented in:: InputMaskDateTime

onItemValuePropertyChanged event

An event that is raised when an ItemValue property is changed.

Parameters:

sender: this
A SurveyJS object whose property contains an array of ItemValue objects.
options.obj: ItemValue
An ItemValue object.
options.propertyName: string
The name of the property to which an array of ItemValue objects is assigned (for example, "choices" or "rows").
options.name: "text" | "value"
The name of the changed property.
options.newValue: any
A new value for the property.

Type:: Event<(sender: Base, options: any) => any, Base, any>

Implemented in:: Base

onPropertyChanged event

An event that is raised when a property of this SurveyJS object has changed.

Parameters:

sender: this
A SurveyJS object whose property has changed.
options.name: string
The name of the changed property.
options.newValue: any
A new value for the property.
options.oldValue: any
An old value of the property. If the property is an array, oldValue contains the same array as newValue does.

If you need to add and remove property change event handlers dynamically, use the registerPropertyChangedHandlers and unregisterPropertyChangedHandlers methods instead.

Type:: EventBase<Base, any>

Implemented in:: Base

pattern property

A pattern for the input value.

If you set the maskType to "pattern", the mask can contain string literals and the following placeholders:

9 - A digit.
a - An upper- or lower-case letter.
# - A digit or an upper- or lower-case letter.

Use backslash \ to escape a character.

Example: +1(999)-999-99-99

If you set the maskType to "datetime", the mask can contain separator characters and the following placeholders:

m - Month number.
mm - Month number, with leading zero for single-digit values.
d - Day of the month.
dd - Day of the month, with leading zero for single-digit values.
yy - Last two digits of the year.
yyyy - A four-digit year.
H - Hours in 24-hour format.
HH - Hours in 24-hour format, with leading zero for single-digit values.
h - Hours in 12-hour format.
hh - Hours in 12-hour format, with leading zero for single-digit values.
MM - Minutes.
ss - Seconds.
TT - 12-hour clock period in upper case (AM/PM).
tt - 12-hour clock period in lower case (am/pm).

Example: mm/dd/yyyy HH:MM:ss

registerPropertyChangedHandlers method

Registers a single value change handler for one or multiple properties.

The registerPropertyChangedHandlers and unregisterPropertyChangedHandlers methods allow you to manage property change event handlers dynamically. If you only need to attach an event handler without removing it afterwards, you can use the onPropertyChanged event instead.

Type:: (propertyNames: string[], handler: any, key?: string) => void

Parameters:: propertyNames, type: string[] ,
An array of one or multiple property names.

handler, type: any ,
A function to call when one of the listed properties change. Accepts a new property value as an argument.

key, type: string ,
(Optional) A key that identifies the current registration. If a function for one of the properties is already registered with the same key, the function will be overwritten. You can also use the key to subsequently unregister handlers.

Implemented in:: Base

See also:: unregisterPropertyChangedHandlers

saveMaskedValue property

Specifies whether to store the question value with an applied mask in survey results.

Default value: false

Type:: boolean readonly

This property is stored in the survey JSON definition and can be edited in the Survey Creator.

Implemented in:: InputMaskBase

setPropertyValue method

Assigns a new value to a specified property.

Type:: (name: string, val: any) => void

Parameters:: name, type: string ,
A property name.

val, type: any ,
A new value for the property.

Implemented in:: Base

toJSON method

Returns a JSON object that corresponds to the current SurveyJS object.

Type:: (options?: ISaveToJSONOptions) => any

Parameters:: options, type: ISaveToJSONOptions

Implemented in:: Base

See also:: fromJSON

unregisterPropertyChangedHandlers method

Unregisters value change event handlers for the specified properties.

Type:: (propertyNames: string[], key?: string) => void

Parameters:: propertyNames, type: string[] ,
An array of one or multiple property names.

key, type: string ,
(Optional) A key of the registration that you want to cancel.
