react-popout

React popout is a React component wrapping window.open allowing you to host content in a browser popup window.

npm install react-popout --save

Demo

To see it in action just go to http://jake.ginnivan.net/react-popout

Usage

The usage is really simple, when the component is mounted the popup is open, when it is unmounted the popup is closed.

<Popout url='popout.html' title='Window title' onClosing={this.popupClosed}>
  <div>Popped out content!</div>
</Popout>

To close the window programatically give the window a ref and use the closeWindow function.

props

title [required]

Title for popup window

url [optional]

Url of the page to load intially. Often needed for css. about:blank will be used if not specified

onClosing [optional]

Called when popout window is closed, either by user or by calling close

options [optional]

Object representing window options. See https://developer.mozilla.org/en-US/docs/Web/API/Window/open#Position_and_size_features for reference.

Example: <Popout options={{left: '100px', top: '200px'}} />

By default 500px wide, 400px high and centered over the window hosting the react component.

You can also specify a function with signature (options, window) => { } to perform calculations. For example top is calculated with (o, w) => ((w.innerHeight - o.height) / 2) + w.screenY

window [optional]

Instead of using the window global, a window object can be passed in. It needs the following functions on it:

window.open(<url>, <title>, <strWindowFeatures>); and return an object which looks like this:

{
  onbeforeunload: () => { },
  onload: () => { },
  close: () => { },
  document: {
    title: string,
    body: {
      appendChild: (ele) => { }
    }
  }
}

This can be used if you need to intercept the calls and do something else.

containerID [optional]

Assigns an Id to the container that will be injected in the popup window document.body, defaults to popout-content-container, useful for cascading styles.

Example:

// input
<Popout containerId='tearoff'>
  <SomeComponent />
</Popout>

// output in new window:
<div id="tearoff">
  <SomeComponent />
</div>

Example hosting component

class HostingComponent {
  constructor(props) {
    super(props);
    this.popout = this.popout.bind(this);
    this.popoutClosed = this.popoutClosed.bind(this);
    this.state = { isPoppedOut: false };
  }

  popout() {
    this.setState({isPoppedOut: true});
  }

  popoutClosed() {
    this.setState({isPoppedOut: false});
  }

  render() {
    if (this.state.isPoppedOut) {
      return (
        <Popout url='popout.html' title='Window title' onClosing={this.popoutClosed}>
          <div>Popped out content!</div>
        </Popout>
      );
    } else {
      var popout = <span onClick={this.popout} className="buttonGlyphicon glyphicon glyphicon-export"></span>
      return (
        <div>
          <strong>Section {popout}</strong>
          <div>Inline content</div>
        </div>
      );
    }
  }
}

The popped out content can have props set and will render just as you would expect a normal React component to render.
