:mouse: Fire mouse events when a user intends it

hoverintent

hoverintent is a reworking of Brian Cherne's jQuery plugin in plain javascript. It has no dependencies.

It's goal is to determine a user's intention when hovering over an element by triggering a mouseover event when the cursor position has slowed down enough.

Check out the demo to see how it works in action.

Basic usage

Adding hoverintent to an element

<script src='hoverintent.min.js'></script>
<script>
  var el = document.getElementById('element-id');
  hoverintent(el,
  function() {
    // Handler in
  }, function() {
    // Handler out
  });
</script>

Removing hoverintent from an element

<script src='hoverintent.min.js'></script>
<script>
  var el = document.getElementById('element-id');

  // Save a reference to the method
  var hoverListener = hoverintent(el,
  function() {
    // Handler in
  }, function() {
    // Handler out
  });

  // Remove hoverintent listeners
  hoverListener.remove();
</script>

Custom options

You can adjust mouse sensitivity or the length of time a mouse over/out event is fired:

<script src='hoverintent.min.js'></script>
<script>
  var opts = {
    timeout: 500,
    interval: 50
  };

  var el = document.getElementById('element-id');
  hoverintent(el,
  function() {
    // Handler in
  }, function() {
    // Handler out
  }).options(opts);
</script>

Setting	Default Value	Description
sensitivity	sensitivity: 7	The value (in pixels) the mouse cursor should not travel beyond while hoverintent waits to trigger the mouseover event.
interval	interval: 100	The length of time (in milliseconds) hoverintent waits to re-read mouse coordinates.
timeout	timeout: 0	The length of time (in milliseconds) before the mouseout event is fired.
handleFocus	handleFocus: false	Adds onOver/onOut callbacks to keyboard navigation during blur and focus events

Ender support

    // Handler in
}, function() {

});
