Property |
Description |
|
(Required as of July 2018) API key to access Google map resources. Without an API key, a darkened map with the text "For development purposes only" will display. For information on obtaining an API key, visit https://developers.google.com/maps/documentation/javascript/get-api-key. The API key for each site will be different; therefore, an expression would most likely be used to supply the value for the APIkey$ property. However, you can leave the APIkey$ property blank and simply load the %GoogleAPIkey$ variable with the API key value prior to displaying any maps (such as in the START_UP program), and the PxPlus map object will retrieve the key value from there and set this property automatically without having to set it for each individual map. Note:
