Route search function with more than 8 waypoints using Google Maps API v3
function searchLongRoute(waypoints) {
var route;
var unit = 10;
var unit_num = Math.ceil((waypoints.length+Math.ceil(waypoints.length/unit)-1)/unit);
for (var start_num = 0; start_num < waypoints.length-1;) {
var s = waypoints[start_num];
var next_start = ((waypoints.length>=start_num+unit)?(start_num+unit):(waypoints.length))-1;
var e = waypoints[next_start];
var w = waypoints.slice(start_num+1, next_start);
direction.route({
'origin': s.location,
'destination': e.location,
'travelMode': tMode,
'waypoints': w,
'avoidHighways': true,
'avoidTolls': true
}, function(ret, st){

if (route) {
route.routes[0].legs = route.routes[0].legs.concat(ret.routes[0].legs);

}
} else {
