The Zoom attribute is used to increase or decrease the zoom level on a specific point in maps. To customize the zoom level change the zoom value. The default value of zoom is 10.
Syntax:
var CustomOp = { zoom:zoom value };
Example 1: This example sets the zoom level at 10.
<!DOCTYPE html> < html >       < head >     < title >         Google Maps | Zoom     </ title >       <!-- Loading map API -->     < script src =     </ script >              < script >         function GFG() {                            var CustomOp = {                 center:new google.maps.LatLng(                             28.502212, 77.405603),                 zoom:10,                 mapTypeId:google.maps.MapTypeId.ROADMAP             };                            // Map object             var map = new google.maps.Map(                 document.getElementById("DivID"),                 CustomOp             );         }     </ script > </ head >   <!-- load map --> < body onload = "GFG()" >     < center >         < h1 style = "color:green" >neveropen</ h1 >         < h3 >Google Maps</ h3 >                   <!-- Basic Container -->         < div id = "DivID" style =             "width:400px; height:300px;" >         </ div >     </ center > </ body >       </ html > |
