问题描述
我传递lat和lng变量并在div中显示google sreet视图。问题是,当StreetView不可用时,则不显示任何内容。我想检查是否有给定经纬度和街景的街景并显示一条消息。这里是我的代码:
I am passing lat and lng variables and display google sreet view in a div. The problem is that when the StreetView is unavilable then nothing is displayed. I would like to check if there is a streetview for a given lat and lng and display a message. Here is my code:
var myPano = new GStreetviewPanorama(document.getElementById("street2"), panoOpts);
var location = new GLatLng(lat,lng)
myPano.setLocationAndPOV(location);
也许我应该使用类似于: Event.addListener(myPano,error ,errorMessage());
Maybe I should use something like: Event.addListener(myPano, "error", errorMessage());
有什么想法吗?
Any ideas?
推荐答案
在v3中这已经改变了一点。请参阅
In v3 this has changed a bit. Check out the documentation at http://code.google.com/apis/maps/documentation/javascript/reference.html#StreetViewService
更新的代码是:
The updated code is:
var streetViewService = new google.maps.StreetViewService();
var STREETVIEW_MAX_DISTANCE = 100;
var latLng = new google.maps.LatLng(40.7140, -74.0062);
streetViewService.getPanoramaByLocation(latLng, STREETVIEW_MAX_DISTANCE, function (streetViewPanoramaData, status) {
if (status === google.maps.StreetViewStatus.OK) {
// ok
} else {
// no street view available in this range, or some error occurred
}
});
