Alternate View Google Map JavaScript Methods
Description
Methods can be called directly on the JavaScript object for the Grid Map object in the Grid Component.
These are method of the Grid map object, which is not the same as the Google map object. To get a pointer to the Grid map object, use this syntax:
var mapId = {grid.object}.googleMap_mapId;The map id is defined in the Alternate View properties.
So, for example, if the map Id is 'VIEW1', the pointer to the Grid map object is:
var view1Id = {grid.object}.googleMap_VIEW1;To get a pointer to the underlying Google map object you add .map to the Grid map object. For example:
var mapObj = {grid.object}.googleMap_VIEW1.map;Once you have a pointer to the Google map object, you can refer to the Google Maps API documentation to see what methods are available.
