Accessible modal dialog component for React.JS
<Modal
isOpen={bool}
onAfterOpen={afterOpenFn}
onRequestClose={requestCloseFn}
closeTimeoutMS={n}
style={customStyle}
>
<h1>Modal Content</h1>
<p>Etc.</p>
</Modal>
Styles are passed as an object with 2 keys, 'overlay' and 'content' like so
{
overlay : {
position : 'fixed',
top : 0,
left : 0,
right : 0,
bottom : 0,
backgroundColor : 'rgba(255, 255, 255, 0.75)'
},
content : {
position : 'absolute',
top : '40px',
left : '40px',
right : '40px',
bottom : '40px',
border : '1px solid #ccc',
background : '#fff',
overflow : 'auto',
WebkitOverflowScrolling : 'touch',
borderRadius : '4px',
outline : 'none',
padding : '20px'
}
}
Styles passed to the modal are merged in with the above defaults and applied to their respective elements. At this time, media queries will need to be handled by the consumer.
If you prefer not to use inline styles or are unable to do so in your project,
you can pass className
and overlayClassName
props to the Modal. If you do
this then none of the default styles will apply and you will have full control
over styling via CSS.
The default styles above are available on Modal.defaultStyles
. Changes to this
object will apply to all instances of the modal.
Inside an app:
var React = require('react');
var ReactDOM = require('react-dom');
var Modal = require('react-modal');
var appElement = document.getElementById('your-app-element');
/*
By default the modal is anchored to document.body. All of the following overrides are available.
* element
Modal.setAppElement(appElement);
* query selector - uses the first element found if you pass in a class.
Modal.setAppElement('#your-app-element');
*/
const customStyles = {
content : {
top : '50%',
left : '50%',
right : 'auto',
bottom : 'auto',
marginRight : '-50%',
transform : 'translate(-50%, -50%)'
}
};
var App = React.createClass({
getInitialState: function() {
return { modalIsOpen: false };
},
openModal: function() {
this.setState({modalIsOpen: true});
},
afterOpenModal: function() {
// references are now sync'd and can be accessed.
this.refs.subtitle.style.color = '#f00';
},
closeModal: function() {
this.setState({modalIsOpen: false});
},
render: function() {
return (
<div>
<button onClick={this.openModal}>Open Modal</button>
<Modal
isOpen={this.state.modalIsOpen}
onAfterOpen={this.afterOpenModal}
onRequestClose={this.closeModal}
style={customStyles} >
<h2 ref="subtitle">Hello</h2>
<button onClick={this.closeModal}>close</button>
<div>I am a modal</div>
<form>
<input />
<button>tab navigation</button>
<button>stays</button>
<button>inside</button>
<button>the modal</button>
</form>
</Modal>
</div>
);
}
});
ReactDOM.render(<App/>, appElement);
When using React Test Utils with this library, here are some things to keep in mind:
- You need to set isOpen={true} on the modal component for it to render its children.
- You need to use the
.portal
property, as inReactDOM.findDOMNode(renderedModal.portal)
orTestUtils.scryRenderedDOMComponentsWithClass(Modal.portal, 'my-modal-class')
to acquire a handle to the inner contents of your modal.
By default the modal is closed when clicking outside of it (the overlay area). If you want to prevent this behavior you can pass the 'shouldCloseOnOverlayClick' prop with 'false' value.
<Modal
isOpen={bool}
onAfterOpen={afterOpenFn}
onRequestClose={requestCloseFn}
closeTimeoutMS={n}
shouldCloseOnOverlayClick={false}
style={customStyle}>
<h1>Force Modal</h1>
<p>Modal cannot be closed when clicking the overlay area</p>
<button onClick={handleCloseFunc}>Close Modal...</button>
</Modal>
