This is still verrrrrrrry beta, and the api is subject to change. Please, don't use in critical financial infrastructure quite yet.

Install

Example

Live demo

view source

var React = require('react');
var Completion = require('../react-completion');
var states = require('./states.json');

var Example = React.createClass({

	getInitialState: function() {
		return {
			text: ''
		};
	},

	handleChange: function(ev) {
		this.setState({
			text: ev.target.value
		});
	},

	handleSuggestionChange: function(suggestion) {
		console.info('the suggestion changed to ' + suggestion);
	},

	handleSuggestionAccept: function(suggestion) {
		console.info('the user accepted the suggestion: ' + suggestion);
		this.setState({
			text: suggestion
		});
	},

	render: function() {
		return (
			<div style={this.style.wrapper}>
				<Completion
					suggestions={states}
					value={this.state.text}
					onChange={this.handleChange}
					onSuggestionChange={this.handleSuggestionChange}
					onSuggestionAccept={this.handleAccept}/>
			</div>
		);
	},

});

React.render(<Example/>, document.getElementById('app'));

Run

To run examples on the local machine:

$ git clone [email protected]:holmesal/react-completion.git
$ cd react-completition
$ npm install
$ npm run example

Properties

This component wraps an <input>, so all input-compatible properties are supported. Note the use of the onChange property in the above example.

• suggestions Array of Strings required - the suggestions to be matched

• value String required - the text value of the input

• acceptOnEnter Boolean (default true) - hitting the Enter key will accept the current suggestion

• acceptOnTab Boolean (default true) - hitting the Tab key will accept the current suggestion

• onSuggestionChange(suggestion) - called when the suggestion changes.

• onSuggestionAccept(suggestion) - called when the user accepts a suggestion by pressing tab.

Gotchas

.focus()

Because you're asking a react component to .focus() instead of an HTML element, you need to use the form

this.refs.yourCompletionRef.focus()

instead of

React.findDOMNode(this.refs.yourCompletionRef).focus().

Exposing component functions doesn't seem especially encouraged in the docs. Have a better idea for this API? Send a PR!

todo

• Add support for uncontrolled components
• Add props to style the <input> and suggestion styles
• Add the ability to cycle through suggestions with the up/down arrow keys
• Unit testssssssssss
