要在路线上制作自定义Google地图标记的动画,您可以使用Google Maps JavaScript API。以下是一些关键步骤:
setTimeout
或requestAnimationFrame
等方法实现动画效果。以下是一个简单的示例代码:
function initMap() {
const map = new google.maps.Map(document.getElementById("map"), {
zoom: 16,
center: { lat: 40.730610, lng: -73.935242 },
});
const customMarker = new CustomMarker(map, {
position: { lat: 40.730610, lng: -73.935242 },
map: map,
animation: google.maps.Animation.DROP,
});
customMarker.setAnimation(google.maps.Animation.BOUNCE);
}
class CustomMarker extends google.maps.OverlayView {
constructor(map, options) {
super();
this.setMap(map);
this.options = options;
this.div = document.createElement("div");
this.div.style.borderStyle = "none";
this.div.style.borderWidth = "0px";
this.div.style.position = "absolute";
}
onAdd() {
this.getPanes().markerLayer.appendChild(this.div);
}
draw() {
const overlayProjection = this.getProjection();
const point = overlayProjection.fromLatLngToDivPixel(
this.options.position
);
this.div.style.left = point.x + "px";
this.div.style.top = point.y + "px";
}
onRemove() {
this.div.parentNode.removeChild(this.div);
this.div = null;
}
setAnimation(animation) {
this.options.animation = animation;
this.animate();
}
animate() {
const delay = 100;
switch (this.options.animation) {
case google.maps.Animation.BOUNCE:
this.div.style.animation = "bounce 1s infinite";
break;
case google.maps.Animation.DROP:
this.div.style.animation = "drop 1s";
break;
default:
break;
}
}
}
在这个示例中,我们创建了一个自定义覆盖物类CustomMarker
,并设置了其样式和动画效果。然后,我们将自定义覆盖物添加到地图上,并设置其位置。最后,我们使用setAnimation
方法实现动画效果。
您可以根据自己的需求修改这个示例,以实现更复杂的动画效果。
