Uncaught RangeError: Maximum call stack size exceeded when I use google maps
提问by gstackoverflow
I am trying to write simple example with google maps and markers but i faces with error:
我正在尝试使用谷歌地图和标记编写简单的示例，但我遇到了错误：
Uncaught RangeError: Maximum call stack size exceeded
js:
js：
$(document).ready(function() {
var map;
var elevator;
var myOptions = {
zoom: 1,
center: new google.maps.LatLng(0, 0),
mapTypeId: 'terrain'
};
map = new google.maps.Map($('#map_canvas')[0], myOptions);
var markers = [];
coords = [{
lat: 55,
lng: 37
}];
for (var x = 0; x < coords.length; x++) {
var latlng = new google.maps.LatLng(x.lat, x.lng);
var marker = new google.maps.Marker({
position: latlng,
map: map
});
markers.push(marker);
}
fitBounds();
function fitBounds() {
var bounds = calculateBounds();
if (bounds != undefined) {
map.fitBounds(bounds);
}
}
function calculateBounds() {
var allMarkers = markers;
if (allMarkers.length > 0) {
var bounds = new google.maps.LatLngBounds();
for (i = 0; i < allMarkers.length; i++) {
bounds.extend(allMarkers[i].getPosition());
}
}
return bounds;
}
});

The error Uncaught RangeError: Maximum call stack size exceededwhen calling fitBoundsusually means you have called bounds.extendwith an invalid google.maps.LatLngobject.
Uncaught RangeError: Maximum call stack size exceeded调用时的错误fitBounds通常意味着您调用bounds.extend了一个无效的google.maps.LatLng对象。
This is incorrect (x.lat and x.lng are undefined):
这是不正确的（x.lat 和 x.lng 未定义）：
for (var x = 0; x < coords.length; x++) {
var latlng = new google.maps.LatLng(x.lat, x.lng);
var marker = new google.maps.Marker({
position: latlng,
map: map
});
markers.push(marker);
}
It yields latlng with lat: NaN, lng: NaN
它产生 latlng 与 lat: NaN, lng: NaN
Which isn't valid.
这是无效的。
should be:
应该：
for (var x = 0; x < coords.length; x++) {
var latlng = new google.maps.LatLng(coords[x].lat, coords[x].lng);
var marker = new google.maps.Marker({
position: latlng,
map: map
});
markers.push(marker);
}
