问题 Does anyone know if there is a way to refresh the Weather Layer in Google Maps javascript API? To give a little background, we have an application which stays open in the browser and updates some information on the map every few minutes. We let the users open the weather layer on the map, but the weather only loads once, when the layer is created. After a while, it gets outdated and we'd like it to stay current. I've tried everything from recreating the layer and setting the map to null, then

问题 I want to make a specialized type of polygon object that wraps around or inherits from the google.maps.Polygon class. I want it to have a custom edited event that can be listened to, ideally via the normal addListener interface. Can this be done? 回答1: I like JustinY's answer. An alternative would be manually triggering an event like this: function CustomPolygon(options) { var self = this; // initialize any options console.log('init') } function edit() { // do work!!! // now tell people about

问题 I have a JSON array of Marker positions being pulled into a Google map - This works fine. I also have infoWindows linked to each of those markers - These also work fine. However, when I click a marker (in any browser), the infoWindow only appears over the last added marker. Here is a fiddle: http://jsfiddle.net/neuroflux/8WDwn/10/ and here is my loop: for (var a = 0; a < dealer_markers.length; a++) { var tmpLat = dealer_markers[a].lat; var tmpLng = dealer_markers[a].lng; var tmpName = dealer

问题 I'm using Google Maps JS V3 API on my website. I'm able to use getDetails by placeId when user searches for a place. I would like to do the same when user clicks on a POI. However, I can't seem to find a way to get this placeId when user clicks on a POI instead of using the search box. I have done research for days, and had no luck of finding anything close. I came across this feature request, I wonder if there is really no way of getting the placeId by POI clicking: https://code.google.com/p

问题 I created a script to store dynamic map inputs by appending attributes to a Static Maps URL (so we can refer back to it after a user submits). For reasons I can't yet determine, the Polygon is not rendering at all with the basic static maps URL, but it works with a 3rd party site's static maps function. According to Static Maps API examples there should be no issue, but I can't seem to recreate the Polygon. Working version (with same attributes in URL, though it ignores Satellite and zoom
