当前代码检索所有信息,在地图上显示所有标记,如果单击标记,则 infowindow 呈现显示其内容。我想做的是我想在这方面实施指导。如何在我的代码中添加方向,以便它也添加方向?这就是我想要实现的:
要实施什么:
var request = {
origin: start,//it will be my first row(lat and lon)
destination: end,//it will be my lastrow(lat and lon)
waypoints: waypts, // it will be all lat and lon between first and last
optimizeWaypoints: true,
travelMode: google.maps.TravelMode.DRIVING
};
directionsService.route(request, function(response, status){
if (status == google.maps.DirectionsStatus.OK){
directionsDisplay.setDirections(response);
}
});
我想要实现上述功能的当前代码意味着谷歌地图方向:
已经实施:
$("#directions").click(function(){
var lat_from_ip = $("#hidden_lat").val();
var lon_from_ip = $("#hidden_lon").val();
var latlng = new google.maps.LatLng(lat_from_ip, lon_from_ip);
var options = {zoom: 4, center: latlng, mapTypeId: google.maps.MapTypeId.ROADMAP};
var map = new google.maps.Map(document.getElementById('map'), options);
$.ajax({type: "GET",
dataType: 'json',
url: url +'//abc/my_page.php',
success: function(response){
var total=response.length;
var data_array,name,type,address,lat,lon,infowindow;
var infowindow = new google.maps.InfoWindow();
for(var i=0; i < total; i++)
{
data_array=response[i];
name=data_array['name'];
address=data_array['address'];
notes=data_array['notes'];
lat=data_array['lat'];
lon=data_array['lon'];
var propPos = new google.maps.LatLng(lat,lon);
propMarker = new google.maps.Marker({
position: propPos,
map: map,
icon: icon,
zIndex: 3});
var contentString = "<div>"+name+"<br/><label class='label'>Location :</label> "+address+"<br/><label class='label'>Notes :</label> "+notes + "</div>";
function bindInfoWindow(marker, map, infowindow, html) {
google.maps.event.addListener(marker, 'click', function() {
infowindow.setContent(html);
infowindow.open(map, marker);
});
}
bindInfoWindow(propMarker, map, infowindow, contentString);
} //end of for loop
} //end of for success
}); //end of for $.ajax
return;
});
