React Hoverintent

react-hoverintent is a react wrapper over jquery-hoverintent plugin.

"hoverIntent is a plug-in that attempts to determine the user's intent... like a crystal ball, only with mouse movement! It is similar to jQuery's hover method. However, instead of calling the handlerIn function immediately, hoverIntent waits until the user's mouse slows down enough before making the call."

jquery-hoverintent.

Installation

npm install react-hoverintent

Demo

The demo with live examples can be viewed here.

Props

onMouseOver : The callback to fire on mouse over event

onMouseOut : The callback to fire on mouse out event

timeout : A simple delay, in milliseconds, before the onMouseOut callback is fired. If the user mouses back over the element before the timeout has expired the onMouseOut callback will not be called (nor will the onMouseOver callback be called). This is primarily to protect against sloppy/human mousing trajectories that temporarily (and unintentionally) take the user off of the target element... giving them time to return.

Default timeout: 0

sensitivity : If the mouse travels fewer than this number of pixels between polling intervals, then the onMouseOver callback will be called. With the minimum sensitivity threshold of 1, the mouse must not move between polling intervals. With higher sensitivity thresholds you are more likely to receive a false positive.

Default sensitivity: 7

interval : The number of milliseconds hoverIntent waits between reading/comparing mouse coordinates. When the user's mouse first enters the element its coordinates are recorded. The soonest the onMouseOut callback can be called is after a single polling interval. Setting the polling interval higher will increase the delay before the first possible onMouseOver call, but also increases the time to the next point of comparison.

Default interval: 700

Use

import HoverIntet from 'react-hoverintent'
import classnames from 'classnames'
 
class App extends Component {
  constructor () {
    super()
    this.state = { mouseover: false }
    this.onMouseOver = this.onMouseOver.bind(this)
    this.onMouseOut = this.onMouseOut.bind(this)
  }
  onMouseOver () {
    this.setState({mouseover: true})
  }
  onMouseOut () {
    this.setState({mouseover: false})
  }
  render () {
    let {mouseover} = this.state
    return (
      <div className='container'>       
        <HoverIntent

          onMouseOut={this.onMouseOut}
          sensitivity={10}
          interval={1000}
          timeout={250}
        >
         <button>Hover</button>
        </HoverIntent>
