javascript map in leaflet how to refresh

Question

i have a basic geoJson program in javascript by using leaflet API.

Answer 1

Last time I've used

map._onResize(); 

and that help me refresh map. Maybe a little hack, but, it work.

In your code will be area._onResize()

P.S: Maybe you should try change the way to set new opacity value - try change

function clicked(){
    this.options.style.fillOpacity = 0.8;
 }

to that

function clicked(){
    this.setStyle({fillOpacity: 0.2});
 }

Answer 2

map.invalidateSize();

map._onResize() - it's a hack, and there is no guarantee that it won't be removed in future versions.

Answer 3

area.fitBounds(area.getBounds());
