coordinate grid

[Olga Efremova]

Dear friends! I would like to show coordinate grid on my map in jsp page. I use tiles, becfuse work offline.

This is code:

var map = L.map('map').setView([54.46, 38.70], 1);

map.setMaxBounds([[90, -180], [-90, 180]]);

L.tileLayer('Tiles//{z}/{x}/{y}.png',{ noWrap: true}).addTo(map);

How can I show  coordinate grid on my map? Plese, help me! I've lost 2 days and can not to find solution.
