How do you use the .off() event method in leaflet.js?
geocoding, javascript, leaflet
Solution
You need to pass the function to `on` and `off` by reference:
function doStuff() { ... }
map.on('click', doStuff);
...
map.off('click', doStuff);
Problem
I am trying to build a map application using leaflet.js and I can not figure out how to use the .off method. The documentation doesn't have any examples and I can't seem to find anything anywhere else online. I have distilled the problem into a more simple chunk of code so my question could be more clear. Basically I have it set up so that when you click the 'enable click' link it will add an event listener that adds a marker to the map every time you click it. I want to remove that event listener when you click 'disable click'. Here is a link to the demo Here is the code I have now. ``` $(document).ready(function(){ var map, cloudmade, sanAntonio, polygonPoints map = new L.Map('map'); cloudmade = new L.TileLayer('http://{s}.tile.cloudmade.com/d4334cd6077140e3b92ccfae2b363070/997/256/{z}/{x}/{y}.png', { attribution: 'Map data © <a href="http://openstreetmap.org">OpenStreetMap</a> contributors, <a href="http://creativecommons.org/licenses/by-sa/2.0/">CC-BY-SA</a>, Imagery © <a href="http://cloudmade.com">CloudMade</a>', maxZoom: 18 }); sanAntonio = new L.LatLng(29.4238889, -98.4933333); // geographical point (longitude and latitude) map.setView(sanAntonio, 13).addLayer(cloudmade); //everything above sets up the map function enableClick(){ map.on('click', function(e) { var marker = new L.Marker(e.latlng, {draggable:true}); map.addLayer(marker); });//closes the click function this.disableClick = function(){ map.off('click'); } } //when $('#enable_click').click(function(){ var enable_click = new enableClick() $('#disable_click').click(function(){ enable_click.disableClick; }); }); });//closes the document ready function ``` I have already tried a bunch of different things so the whole 'this.disableClick' thing is just the latest strange thing I have tried. Anyone have a clue?
