Numeric Entry
A numeric entry type question is a variation of a text entry question that accepts only numbers. This example demonstrates different types of numeric data entry questions supported by SurveyJS Form Library. Switch between React, Vue, Knockout, jQuery, and Angular to view an example for your JavaScript framework.
Create a Numeric Entry Question
To create a numeric entry form field, define an object with the type
property set to "text"
and add it to the elements
array. Within this object, specify the question's title
and a unique name
that identifies the numeric input question. Optionally, you can specify a description
to place under the title
and a placeholder
to show within the number input box.
Specify Input Type
If a question requires specific numerical input, use the inputType
property to specify the input type. An inputType
value is passed on to the type
attribute of the underlying <input>
HTML element. This example demonstrates the "number"
, "range"
, and "tel"
input types.
In addition, you can specify the autocomplete
property to let the browser suggest autofill values. For example, the "Phone number" form field in this demo can be populated automatically if your browser contains autofill phone numbers.
Validate Numeric Values
If you need to ensure that respondents fill out all required form fields and the format of values is correct, enable data validation. This example demonstrates the following validation types and describes how to configure them:
Required Validation
Enable theisRequired
property for the form fields that should not be empty.Number Range Validation
Define an object with thetype
property set to"numeric"
and add it to thevalidators
array. Use theminValue
andmaxValue
properties within this object to specify the range. Alternatively, you can use themin
andmax
properties in the question object as shown in this demo.RegEx Validation
Define an object with thetype
property set to"regex"
and add it to thevalidators
array. Assign a regular expression to theregex
property within this object (see the "Phone number" form field in this demo).
