Handling Multiple Polygon Object

阅读更多关于 Handling Multiple Polygon Object

问题 Am trying to add/remove multiple polygon on the google map. On clicking each polygon, I have to show some info window for the corresponding polygon. On clicking the polygon, I couldn't maintain the polygon object. Sample code: for (var i = 0; i < multipleFlights.length; i++) { google.maps.event.addListener(multipleFlights[i], 'click', arrayfn); // $(multipleFlights[i]).click(function () { alert('x'); }); } How can I get the current polygon object in the arrayfn function . Thanks in advance

阅读更多关于 Google Maps does not render correctly in IE8 within iframe nyromodal layer

问题 I try to render a google map within a nyromodal iframe layer. It works fine in Chrome and Firefox, but in IE8 there is a strange issue: On first load, it works fine. Yet after I close the layer and reopen it on the same page, the map will render false: only mostly showing grey tiles and and and all its content will be splattered randomly, e.g. like so: If I clear the cache and reload, the map will work again but only one time. 回答1: The problem most likely lies within the fact that nyromodal

How does Google keep track of map loads without API key?

阅读更多关于 How does Google keep track of map loads without API key?

问题 I am implementing Google Maps in my web application. Since Version 3 I don't need an API key for accessing their servers. Google is limiting the requests, though. How are they doing that? If external users are accessing my website, one map load is generated. Do I have now about 25,000 map loads per IP address or how to they recognize my application? 回答1: They probably use the location/domain of the current document(this detail will be sended to the Authentication-service).
