HTML Google Map is used to display maps on your webpage. You can simply add a map on your basic HTML page.
Syntax:
<!DOCTYPE html>
<html>
<body>
<h1>First Google Map Example</h1>
<div id="map">My map will go here...</div>
</body>
</html> Set the Map Size
You can set the map size by using the following syntax:
<div id="map" style="width:400px;height:400px;background:grey"></div> How to create a function to set the map properties?
You can set the map properties by creating a function. Here, the function is myMap(). This example shows the Google map centered in London, England.
We have to use the functionalities of Google Maps API provided by a JavaScript library located at Google. Use the following script to refer to the Google Maps API with a callback to the myMap function.
<script src="https://maps.googleapis.com/maps/api/js?callback=myMap"></script> Example:
<!DOCTYPE html>
<html>
<body>
<h1>My First Google Map</h1>
<div id="map" style="width:400px;height:400px;background:grey"></div>
<script>
function myMap() {
var mapOptions = {
center: new google.maps.LatLng(51.5, -0.12),
zoom: 10,
mapTypeId: google.maps.MapTypeId.HYBRID
}
var map = new google.maps.Map(document.getElementById("map"), mapOptions);
}
</script>
<script src="https://maps.googleapis.com/maps/api/js?key=AIzaSyBu-916DdpKAjTmJNIgngS6HL_kDIKU0aU&callback=myMap"></script>
</body>
</html> Example Explanation
mapOptions: It is a variable which defines the properties for the map.
center: It specifies where to center the map (using latitude and longitude coordinates).
zoom: It specifies the zoom level for the map (try to experiment with the zoom level).
mapTypeId: It specifies the map type to display. The following map types are supported: ROADMAP, SATELLITE, HYBRID, and TERRAIN.
var map=new google.maps.Map(document.getElementById(“map”), mapOptions): It creates a new map inside the
element with id=”map”, using the parameters that are passed (mapOptions).
HTML Multiple Maps
You can use different map types in a single example.
Example:
<!DOCTYPE html>
<html>
<body>
<div id="googleMap1" style="width:400px;height:300px;"></div>
<br>
<div id="googleMap2" style="width:400px;height:300px;"></div>
<br>
<div id="googleMap3" style="width:400px;height:300px;"></div>
<br>
<div id="googleMap4" style="width:400px;height:300px;"></div>
<script>
function myMap() {
var mapOptions1 = {
center: new google.maps.LatLng(51.508742,-0.120850),
zoom:9,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var mapOptions2 = {
center: new google.maps.LatLng(51.508742,-0.120850),
zoom:9,
mapTypeId: google.maps.MapTypeId.SATELLITE
};
var mapOptions3 = {
center: new google.maps.LatLng(51.508742,-0.120850),
zoom:9,
mapTypeId: google.maps.MapTypeId.HYBRID
};
var mapOptions4 = {
center: new google.maps.LatLng(51.508742,-0.120850),
zoom:9,
mapTypeId: google.maps.MapTypeId.TERRAIN
};
var map1 = new google.maps.Map(document.getElementById("googleMap1"),mapOptions1);
var map2 = new google.maps.Map(document.getElementById("googleMap2"),mapOptions2);
var map3 = new google.maps.Map(document.getElementById("googleMap3"),mapOptions3);
var map4 = new google.maps.Map(document.getElementById("googleMap4"),mapOptions4);
}
