问题 I want to remove all markers on map when the map is clicked. I am following the documentation here: https://developers.google.com/maps/documentation/javascript/examples/marker-remove I've included the function: function clearMarkers() { setMapOnAll(null); } to be triggered by a click event, but I just get the error: Uncaught ReferenceError: setMapOnAll is not defined There is no other information in the documentation that can help me.

问题 I have Google Maps SDK running with custom markers on an android app. Everything works fine on our test phones -- an S3, an S5 and a DROID. However, when I run the app on Nexus 5 hardware, one type of custom marker stops showing up on the map. While the markers are not showing up, they are still being drawn on the map. We can tap where the marker is supposed to be and it will perform desired behavior. We're super confused about this, especially because another custom marker (that is very

问题 I'm trying to create a store locator based off the static csv example used by Google http://storelocator.googlecode.com/git/examples/panel.html I have recreated this example on my own server but if I edit the csv file in any way, even if I just remove some of the rows it returns a blank map. I was hoping I could use this example as a template by replacing the default values in the csv file with my own(http://storelocator.googlecode.com/git/examples/medicare.csv).

If I tab B again, then I get

问题 I'm using Google Maps v3 API to load a KML layer and want to be able to change the colour of the KML from its default blue without having to edit the KML file itself. Is this possible using JavaScript or some other means? Thanks, Neil 回答1: From my understanding of the documentation, 'no', but it's not especially clear. I'm trying to do a similar thing (but update the colour of mouseover/mouseout). The KML file is loaded by the Google servers, parsed and sent along to your javascript object to

问题 I made polygons editable in Google Maps and now I can change the shape, make holes in it, combine two of more polygons to multipolygons and disaggregate them again. See http://maps.amsterdam.nl/testshape/beheer and read the Instructions in the Legenda to try it yourself. One question I can't figure out is how to combine two overlapping polygons to one polygon with no overlap. Something like this: function(path1, path2) { algorithm... return newPath; } Thank you. 回答1: Thanks a lot for the lib
