эй, вот мой код для карты Google
function temp(){
var device_id=document.getElementById('hide').value;
//alert(device_id);
for(j=0;j<device_id;j++)
{
// alert(document.getElementById('hid'+j).value);
$.ajax({
type: 'post',
url: '<?=base_url()?>index.php/admin/tracking/get_location/'+document.getElementById('hid'+j).value,
// data: 'season_id='+season_id,
dataType: "json",
success: function(msg) {
// directionsDisplay.setMap(null);
deleteOverlays();
$.each(msg,function(index,value){
var newLatlng = new google.maps.LatLng(value['lat'],value['long']);
map.panTo(newLatlng);
if(myPoints.length>0)
{
var oldLatlng=myPoints[myPoints.length-1];
var myCoordinates = [
oldLatlng,
newLatlng
];
var myPath = new google.maps.Polyline({
path: myCoordinates,
strokeColor: "#FF0000",
strokeOpacity: 1.0,
strokeWeight: 2
});
way.push(myPath);
myPath.setMap(map);
}
//var newLatlng = new google.maps.LatLng(value['lat'],value['long']);
myPoints.push(newLatlng);
map.panTo(newLatlng);
})
}
});
}
setTimeout("temp1()",2000);
}
function temp1(){
var device_id=document.getElementById('hide').value;
//alert(device_id);
for(j=0;j<device_id;j++)
{

из функции temp, которую я запустил, root на карте, и после этой функции temp1 я получил непрерывные точки для пути из базы данных.но теперь я хочу напечатать несколько путей на карте, выбрав несколько вариантов выбора.как я могу ????
