How to call Google map APIs

After reading this article, I still read the official materials: developers.google.com/maps/mobile-apps.
 
C # function call baidu or google map API

I did a simple job before, but it seems that html code cannot be displayed. Stick the main JavaScript code and give it to you.

Function initMap (){
CreateMap (); // create a map
SetMapEvent (); // sets map events
AddMapControl (); // Add a control to the map
}
// Create a map function:
Function createMap (){
Var map = new BMap. Map ("dituContent"); // create a map in the Baidu Map container
Var point = new BMap. Point (); // defines a central point coordinate.
Map. centerAndZoom (point, 5); // set the center and coordinates of the map and display the map in the map container
Window. map = map; // store the map variable in the global
}

// Search for map Functions
Function searchMap (){
Var local = new BMap. LocalSearch (map ,{
RenderOptions: {map: map}
});
Map. removeOverlay ();
Var key = document. getElementById ("Index"). value;
Local. search (key );
}
// Map event setting function:
Function setMapEvent (){
Map. enableDragging (); // enables the map drag event. It is enabled by default (not writable)
Map. enableScrollWheelZoom (); // enables zoom in and out of map Rollers
Map. enableDoubleClickZoom (); // enables double-click mouse amplification. It is enabled by default (not writable)
Map. enableKeyboard (); // enable the keyboard to move the map from top to bottom
}
// Map control add function:
Function addMapControl (){
// Add a zoom control to the map
Var ctrl_nav = new BMap. NavigationControl ({anchor: BMAP_ANCHOR_TOP_LEFT, type: BMAP_NAVIGATION_CONTROL_LARGE });
Map. addControl (ctrl_nav );
// Add a thumbnail control to the map
Var ctrl_ove = new BMap. OverviewMapControl ({anchor: BMAP_ANCHOR_BOTTOM_RIGHT, isOpen: 1 });
Map. addControl (ctrl_ove );
// Add a scale control to the map
Var ctrl_sca = new BMap. ScaleControl ({anchor: BMAP_ANCHOR_BOTTOM_LEFT });
Map. addControl (ctrl_sca );
}
InitMap (); // create and initialize a map
