[英]Leaflet animated marker create duplicated markers
我正在将Leaflet与动画标记插件一起使用。 主要思想是创建一个动画标记,该标记到一个地方到另一个地方,最后,在相同的经度和纬度上创建另一个动画标记( 一个 ),再到另一个地方,并删除第一个。
现在,当第一个动画结束时,它将创建两个动画标记。
这是代码的一部分:
function moveDriverToPassengerLocation(driver, passenger) {
// Creating the request for google's direction services
var request = {
origin: driver.startLocation,
destination: passenger.startLocation,
travelMode: 'DRIVING'
};
// Sending the request
directionsService.route(request, function (result, status) {
// Verify if the status is ok for getting the path
if (status == 'OK') {
// Decoding the polyline
var decodedPath = L.PolylineUtil.decode(
result.routes[0].overview_polyline);
// Verify if the path has more than one point
if (decodedPath.length > 1) {
var line = L.polyline(decodedPath);
// Creating the new animated marker
var marker = L.animatedMarker(line.getLatLngs(),
{
distance: 300,
interval: 2000,
icon: taxiIcon,
onEnd: function() {
map.removeLayer(this);
moveDriverToPassengerDestination(driver, passenger)
}
}).addTo(map);
marker.id = driver.id;
marker.startLocation = driver.startLocation;
driversMarkers.push(marker);
marker.start();
}
}
});
}
function moveDriverToPassengerDestination(driver, passenger) {
// Creating the request for google's direction services
var request = {
origin: passenger.startLocation,
destination: passenger.destination,
travelMode: 'DRIVING'
};
// Sending the request
directionsService.route(request, function (result, status) {
// Verify if the status is ok for getting the path
if (status == 'OK') {
// Decoding the polyline
var decodedPath = L.PolylineUtil.decode(result.routes[0]
.overview_polyline);
// Verify if the path has more than one point
if (decodedPath.length > 1) {
var line = L.polyline(decodedPath);
// Creating the new animated marker
var marker = L.animatedMarker(line.getLatLngs(),
{
distance: 300,
interval: 2000,
icon: taxiIcon,
onEnd: function() {
map.removeLayer(this);
}
}).addTo(map);
marker.id = driver.id;
marker.startLocation = driver.startLocation;
driversMarkers.push(marker);
marker.start();
}
}
});
}
编辑:
经过一点调试后,我发现onEnd函数在第一个动画标记中可能运行了两次,可能在第二个标记中也运行了两次,但是我仍然不知道为什么会这样。
我刚移走
marker.start();
并在创建标记时添加了这一行
autoStart: true
因此,标记的创建最终如下所示:
var marker = L.animatedMarker(line.getLatLngs(),
{
distance: 300,
interval: 2000,
autoStart: true,
icon: taxiIcon,
onEnd: function() {
map.removeLayer(this);
driver.isMoving = false;
addDriverMarker(driver);
}
}).addTo(map);
它解决了问题。
