Javascript event triggered by pressing space

by

These events bubble up, so if you’re trying to trigger the event wherever your focus is (ie. not in an input), just bind a handler on window:

$(window).keypress(function (e) {
  if (e.key === ' ' || e.key === 'Spacebar') {
    // ' ' is standard, 'Spacebar' was used by IE9 and Firefox < 37
    e.preventDefault()
    console.log('Space pressed')
  }
})

Also see the list of all .key values.
