InputMaskNumeric

A class that describes an input mask of the "numeric" 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": "numeric",
    "maskSettings": {
      // Specify the properties of a numeric input mask here
    }
  }]
}
