Tekstinput

Tekstinput is a user interface element designed to receive textual data from a user. It commonly appears as a single-line field in web forms, mobile apps and desktop applications, allowing people to type letters, numbers and symbols. In web development it is implemented with an input element (often with type attribute set to text), while multi-line text can be captured with a textarea.

Text inputs support attributes and properties such as placeholder text, maximum length, required state, and input patterns for basic client-side validation. They respond to focus, keyboard events and user actions, enabling features such as autocomplete, spelling correction, and input masking. Design and accessibility guidelines emphasize clear labeling, proper association with the corresponding form element, and keyboard navigability. Assistive technologies rely on semantic markup and ARIA attributes to expose the purpose of the text input to screen readers.

Security considerations include sanitizing input to prevent injection attacks and validating on the server side even when client-side checks exist. Common variants include password fields (masking characters), search fields, and URL inputs, each with specialized handling. Some interfaces also offer rich text inputs or contenteditable areas, which differ from simple text inputs by allowing formatting. Tekstinput plays a central role in data collection, form submission, and user interaction across digital platforms, making reliable input handling essential for usability and data integrity.
