Question

使用Google的示例和Stack Overflow上的其他代码中的示例，我汇总了一些带有街道地址并显示高架地图和街景视图的JS。在大多数情况下，这些工作非常好，但是当房子在拐角处时它就会破裂。

当房子在拐角处时，它有时会显示房子的一侧而不是房子的前面。 If I go directly to Google Maps and search for that address, the Street View it shows is actually the front of the house，所以我知道必须有办法确定正确使用的视图。

如何让我的代码显示在Google网站上的房子前面？

function load_map_and_street_view_from_address(address) {
    // Check if GPS has been locally cached.
    var geocoder = new google.maps.Geocoder();
    geocoder.geocode( { 'address': address }, function(results, status) {
        if (status == google.maps.GeocoderStatus.OK) {

            var gps = results[0].geometry.location;
            create_map_and_streetview(gps.lat(), gps.lng(), 'map_canvas', 'pano');
        }
    });
}

function  create_map_and_streetview(lat, lng, map_id, street_view_id) {

    var panorama = new google.maps.StreetViewPanorama(document.getElementById(street_view_id));
    var addLatLng = new google.maps.LatLng(lat,lng);
    var service = new google.maps.StreetViewService();
    service.getPanoramaByLocation(addLatLng, 50, function(panoData, status) {
        if (status != google.maps.StreetViewStatus.OK) {
            $('#pano').html('No StreetView Picture Available').attr('style', 'text-align:center;font-weight:bold').show();
            return;
        }
        var angle = google.maps.geometry.spherical.computeHeading(panoData.location.latLng, addLatLng);

        var panoOptions = {
            position: addLatLng,
            addressControl: false,
            linksControl: false,
            panControl: false,
            zoomControlOptions: {
                style: google.maps.ZoomControlStyle.SMALL
            },
            pov: {
                heading: angle,
                pitch: 0,
                zoom: 1
            },
            enableCloseButton: false,
            visible:true
        };

        panorama.setOptions(panoOptions);
    });

    var myOptions = {
        zoom: 14,
        center: addLatLng,
        mapTypeId: google.maps.MapTypeId.ROADMAP,
        backgroundColor: 'transparent',
        streetViewControl: false,
        keyboardShortcuts: false
    };
    var map = new google.maps.Map(document.getElementById(map_id), myOptions);
    var marker = new google.maps.Marker({
        map:map,
        animation: google.maps.Animation.DROP,
        position: addLatLng
    });
}

$(document).ready(function() {
    console.log('ready');
    load_map_and_street_view_from_address("2131 S SAN ANTONIO AVE, ONTARIO, CA 91762");
});

您正在将全景设置到错误的位置。你想要它在房子的前面（对着公路，使用路线服务），但指向地理编码器的结果。

function create_map_and_streetview(addLatLng, panoLatLng, map_id, street_view_id) {

    var panorama = new google.maps.StreetViewPanorama(document.getElementById(street_view_id));
    var service = new google.maps.StreetViewService();
    service.getPanoramaByLocation(panoLatLng, 50, function (panoData, status) {
        if (status != google.maps.StreetViewStatus.OK) {
            $('#pano').html('No StreetView Picture Available').attr('style', 'text-align:center;font-weight:bold').show();
            return;
        }
        var angle = google.maps.geometry.spherical.computeHeading(panoData.location.latLng, addLatLng);
        document.getElementById('angle').innerHTML = angle;
        var panoOptions = {
            position: panoLatLng,
            pov: {
                heading: angle,
                pitch: 0,

        panorama.setOptions(panoOptions);
