boundless-tokenized-input

TokenizedInput

Basic usage of this component is identical to that of Typeahead. Additional props are available to take advantage of the tokenization functionality.

Component Instance Methods

When using TokenizedInput in your project, you may call the following methods on a rendered instance of the component. Use refs to get the instance.

• add(index: number) programmatically creates a token for props.entities[index]; props.handleAddToken will be called as a hint to persist the change in * your controller view or other application state

• focus() focuses the browser oon the underlying textual input for immediate text entry

• getInputNode() returns the raw underlying textual input DOM node

• getSelectedEntityText() returns the text property of the currently highlighted entity (from props.entities), or returns an empty string

• getValue() retrieves the current value of the underlying textual input

• remove(index: number) programmatically removes the token for props.entities[index]; props.handleRemoveTokens will be called as a hint to persist the * change in your controller view or other application state

• select() programmatically creates a full selection on the underlying textual input such that a press of the Backspace key would fully clear the * input

• setValue(value: string) sets the underlying textual input to the specified text and updates internal state; do not use this method when using Typeahead as a "controlled input"

TokenizedInput can also just be directly used from the main Boundless library. This is recommended when you're getting started to avoid maintaining the package versions of several components:

npm i boundless --save

the ES6 import statement then becomes like:

import { TokenizedInput } from 'boundless';
