Removing Event Listeners

[Elliott]

Hi all,

What is the best way to 'manage' my event listeners?

map.off('click', newWaypoint); //remove previous event listener - works fine

map.on('click', function(e){ //add my new event listener, define the function - works fine

 //do some stuff here, specifically add a marker when user clicks

 

//to stop them adding more markers, i want to go back, 

//remove this event listener, add the 'newWaypoint' one again.

map.off('click'); //can we remove all click event listeners from the map? This is the crux.

map.on('click', newWaypoint); //this line works and is not a problem

});

Pointers would be appreciated.

Cheers,

Elliott

Hi Elliott,

It is best to allways name your callbacks or store them in a variable so you could remove them in code. If you need to use an anonymous function which you remove inside itself, you can do it like this:

map.on('click', function myCallback(e) {

   ...

   map.off('click', myCallback);

});
