README

Leaflet.AlmostOver

This plugin allows to detect mouse click and overing events on lines, with a tolerance distance.

It is useful if paths are drawn with a very small weight, or for clicks detection on mobile devices, for which finger precision can be a problem.

Play with online demo.

It requires Leaflet.GeometryUtil.

Usage

var map = L.map('map');
...
var lines = L.geoJson(...);
...
map.almostOver.addLayer(lines);

map.on('almost:over', function (e) {
    alert('Almost clicked !');
});

Events

Events triggered when mouse is almost over a layer :

• almost:over (latlng, layer)
• almost:move (latlng, layer)
• almost:out (layer)
• almost:click (latlng, layer)
• almost:dblclick (latlng, layer)
