Numbriväljad

Numbriväljad (sing. numbriväli) are input fields used to collect numeric data in digital interfaces and data structures. The term is most commonly encountered in Estonian-language documentation but describes a widely used concept in software design: any field that accepts numbers rather than text.

Implementation and types: In web forms, numeric input is often provided by the HTML input element with type="number". Such fields can specify constraints through attributes like min, max, and step. Some applications implement numeric fields as plain text inputs with validation logic or locale-aware parsers to accommodate decimal separators. Data stored from numbriväljad typically maps to numeric data types in databases, such as integers or floating-point numbers.

Validation and behavior: Valid inputs are checked on the client side for responsiveness and again on the server side for security and data integrity. Many systems support locale-aware formatting, accepting decimal separators appropriate to the user’s locale and converting them to a canonical internal representation.

Accessibility and usability: Designers should pair labels with inputs, provide clear error messages, and ensure keyboard accessibility. Relying solely on spin buttons or strict formatting can hinder users with disabilities or those using assistive technologies.

Security and data integrity: Server-side validation is essential to prevent injection or invalid data. When storing values, applications should choose appropriate numeric types and validate ranges to maintain data consistency. Common use cases include quantities, prices, ages, and statistical scores.
