问题描述
我使用的是Google Maps街景视图,因此我需要在位置上更改全景图,其方式与创建时相同。我正在尝试使用setPosition({lat: -34,lng: 151})
实例的google.maps.StreetViewPanorama
方法来执行此操作,但这没有用。我创建了小提琴,基本上是Google地图街景并排小提琴的副本,唯一的区别是我尝试在2秒后更改位置:https://jsfiddle.net/corecode1/zf0jsL7g/。
我做错什么了吗?还是可能需要在Google云控制台中进行一些其他设置?任何帮助将不胜感激。
代码段(来自小提琴):
"use strict";
function initialize() {
const fenway = {
lat: 42.345573,lng: -71.098326
};
const map = new google.maps.Map(document.getElementById("map"),{
center: fenway,zoom: 14
});
const panorama = new google.maps.StreetViewPanorama(
document.getElementById("pano"),{
position: fenway,pov: {
heading: 34,pitch: 10
}
}
);
map.setStreetView(panorama);
setTimeout(() => {
const newPosition = new google.maps.LatLng({lat: -34,lng: 151});
panorama.setPosition({lat: -34,lng: 151});
},2000);
}
html,body {
height: 100%;
margin: 0;
padding: 0;
}
#map,#pano {
float: left;
height: 100%;
width: 50%;
}

解决方法
新位置返回状态“ ZERO_RESULTS”。
如果您改用(-34.002223,150.994098)
,则可以使用。
一旦失败,它似乎就无法工作。
这有效(如果您不首先加载失败的位置):
setTimeout(() => {
const newPosition = new google.maps.LatLng({lat: -34.002223,lng: 150.994098});
panorama.setPosition(newPosition);
map.setCenter(newPosition);
},4000);
代码段:
"use strict";
function initialize() {
const fenway = {
lat: 42.345573,lng: -71.098326
};
const map = new google.maps.Map(document.getElementById("map"),{
center: fenway,zoom: 14
});
const panorama = new google.maps.StreetViewPanorama(
document.getElementById("pano"),{
position: fenway,pov: {
heading: 34,pitch: 10
}
}
);
map.setStreetView(panorama);
google.maps.event.addListenerOnce(panorama,'position_changed',function() {
console.log(panorama.getPosition().toUrlValue(6));
})
google.maps.event.addListenerOnce(panorama,'status_changed',function() {
console.log(panorama.getStatus());
})
setTimeout(() => {
const newPosition = new google.maps.LatLng({
lat: -34,lng: 151
});
panorama.setPosition(newPosition);
map.setCenter(newPosition);
},6000);
setTimeout(() => {
const newPosition = new google.maps.LatLng({
lat: -34.002223,lng: 150.994098
});
panorama.setPosition(newPosition);
map.setCenter(newPosition);
},4000);
setTimeout(() => {
const newPosition = new google.maps.LatLng({
lat: -34.002223,8000);
