javascript - Progress bar for Leaflet map -


how can show centered on map progress bar (with %) while waiting layer rendered on map?

here code:

<link rel="stylesheet" href="http://cdn.leafletjs.com/leaflet-0.7/leaflet.css" /> <script type='text/javascript' src="http://makinacorpus.github.io/leaflet.spin/leaflet.spin.js"></script> <script type='text/javascript' src="http://makinacorpus.github.io/leaflet.spin/spin.js/dist/spin.min.js"></script> </head> <body> <a href="#" onclick="showmap('http://{s}.tile.thunderforest.com/landscape/{z}/{x}/{y}.png')">tf.landscape</a>&nbsp;|<a href="#" onclick="showmap('http://{s}.tile.thunderforest.com/outdoors/{z}/{x}/{y}.png')">tf.outdoors</a> <div id="map" style="width: 640px; height: 480px"></div> <progress value="0" max="100"></progress>   <script src="http://cdn.leafletjs.com/leaflet-0.7/leaflet.js"> </script> <script>     var map;     var tilelayer;     function showmap (layerurl) {         if(!map) {            map = l.map('map').setview([19.5, -73], 7);          }          tilelayer = l.tilelayer(layerurl, {               attribution: 'map data &copy; <a href="http://openstreetmap.org">openstreetmap</a>',               maxzoom: 18             });         //map.addlayer(tilelayer);            map.spin(true);             settimeout(function () {                 map.addlayer(tilelayer);                     map.spin(false);            }, 3000);       } </script>

thanks!

there not built- or plugged-in solution yet.

  • if progress-bar , % not important , want tell user something's loading might want have @ leaflet.spin plugin showing spinning icon on map.
  • if want progress-bar starting point might markercluster-plugin. 50k example has such progress bar.
