singleclick event

[msaspence]

when a double click occurs two single click events are triggered which is a problem if you want to do something on single click but not double click

the firing of two single click within a double click is browser behaviour but there are possible workarounds

sparkle provides a jquery singleclick that may be usefull

Unfortunately all such workarounds are based on deciding whether to fire click after a particular timeout, and it makes applications that don't care about double-clicking less responsive. So I would implement something like "singleclick" support as a plugin, but not include it in the Leaflet core.

Does such plugin already exist?

[mourner]

Didn't yet heard of any.

[cvisto]

it is a pity. Is there any place where all shared plugins stored?

[mourner]

See my thoughts on this here: #399

See this comment from @michael for an example solution.

Closing as something that should go into a plugin.

I'm working on a favorDoubleClick plugin for this issue. When the plugin is enabled, click events will call their handlers only if no second click happens before a specified timeout. The implementation is straightforward and safe but it requires replacing two core Leaflet functions, so I'm wondering if there's a better way.

Leaflet registers click handlers in various situations. For example, when a marker is added to the map L.Marker.onAdd registers a click handler via L.DomEvent.on. And when a popup is created, L.Layer.bindPopup registers a click handler via L.Evented.on. When the plugin is enabled, these actions must create click handlers which use a timeout as described above.

Strategy: L.favorDoubleClick.enable will replace L.DomEvent.on and L.Evented.on with versions which wrap the passed-in handler to implement the timeout behavior. Since all event binding ultimately uses one of these two core functions, all click handlers will have the desired behavior if the plugin is enabled before anything is added to the map. (To make L.favorDoubleClick.disable trivially simple, the wrapped handlers will only apply the timeout if L.favorDoubleClick.isEnabled.)

If anyone sees a problem with this strategy or has a better strategy, please speak up!
