javascript - How to prevent leaflet from loading tiles outside map area? -

-

i have map 8576x8576, , keep getting console errors:

failed load resource: net::err_file_not_found

because leaflet trying load tiles doesn't exists. have bounds set , maxbounds prevent panning outside map area (to keep map on center of screen).

var map = l.map('map', {     maxzoom: mapmaxzoom,     minzoom: mapminzoom,     zoomcontrol: false,     crs: l.crs.mysimple }).setview([0, 0], 3);  l.tilelayer('assets/map/{z}_{x}_{y}.jpg', {     minzoom: mapminzoom,     maxzoom: mapmaxzoom,     tilesize: 268,     nowrap: true,     reusetiles: true,     tms: false,     bounds: mybounds,     errortileurl: "assets/map/404.jpg",     continuousworld: true }).addto(map);  new l.control.zoom({position: 'topright'}).addto(map);  var sidebar = l.control.sidebar('sidebar').addto(map);  var mybounds = [[-8576 / 2, -8576 / 2],[8576 / 2, 8576 / 2]];  map.setmaxbounds([[-5600, -5600], [5600, 5600]]);

what doing wrong? why leaflet keeps trying load tiles?

i tried set maxbounds this:

map.setmaxbounds([[-8576 / 2, -8576 / 2],[8576 / 2, 8576 / 2]]);

and still errors.

you need define mybounds before creating tilelayer. if bounds lie on edges of tiles, may need bring bounds in tiny amount keep map trying load adjoining tiles. here example osm tiles:

i use winscp download , edit .scss files , sass on linux (on server) compile them .css . after saving file, use: sass scss/style.scss css/style.css , replaces css file compiled sccs. the problem i want skip part return command line after editing scss file, sake of automation , saving time. but, if use watch command: sass --watch scss/style.scss:css/style.css synchronize 2 files, alerts nonexistent css errors pop up: change detected to: scss/style.scss error scss/style.scss (line 232: invalid css after "...ht: bold; line-": expected "{", "") note that when file uploads quicker usual (sometimes happens) watch command job, no errors. this because, when file upload takes time, sass compiles scss file (on server) before uploaded remote folder. thus, compiles part of file, resulting in css errors. is there way set timer watch command waits few seconds after detects changes , before compiling? any other way overcome is, of course, ...
