问题 I am a newbie to Open Street Map. I made some research and found that we can download and store the map into a folder. But i didn't find any tutorial or sample that provides offline Open Street Map. Can someone provide a step by step tutorial, a guide to implement offline open street map please.

问题 I have an array with ~30k elements and I need to create map with markers for each of them. I use markerclusters and trying to optimize adding moment. for (var i = 0; i < myItems.length; i++) { var item = myItems[i]; marker = new L.marker([item[2],item[3]], { icon: mapOpts.myIcon }).bindPopup(item[1]); markers.addLayer(marker); } Even Google Chrome takes about 40 sec to do this loop. I don't want to see FF's result. Is there any way to optimize adding many elements to map? 回答1: var array = [];
