Introduction

In today's modern era, digital maps are beneficial and have become integral to many web applications. They help in representing the data visually and also improve user experience. jQuery, a popular JavaScript library, offers a range of functions that simplify many everyday tasks. In this blog, we will explore one such task, i.e., how to create a simple map using jQuery.

How to Create a Simple Map Using jQuery

In this blog, we will explore how to create a simple map using jQuery. We will also discuss some programming examples for better understanding. Are you ready to learn? Let's get started!

What are Google Maps?

Google Map is a free web-based mapping service application and technology provided by Google. The application provides information about geographical regions, street maps, and satellite views of countries around the globe.

How to Create a Map Using JQuery

This section will discuss how to create a simple map using jQuery. You need to add the given tag to your HTML file to create a simple map using jQuery.

<script src="https://maps.googleapis.com/maps/api/js"></script>

 

You can visit https://console.developers.google.com/flows/enableapi?apiid=maps_backend,geocoding_backend,directions_backend,distance_matrix_backend,elevation_backend,places_backend&reusekey=true to create your project and generate an API key.

<script src="https:maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&callback=initMap" async></script>

Replace the "YOUR_API_KEY" in the above script with your newly generated API key.
 

Now, let's discuss how to create a simple map using jQuery and break down the procedure into the following steps, along with an example.

Step1

Firstly we will create an HTML file and add the script tag, which we discussed earlier in this blog. We will use the functionalities of Google Maps API provided by JavaScript Library to create functions and set map properties. Also, we will create a <div> container with id = "MapID." You can change this id according to yourself, as it performs functions on that particular element. The following code describes our first step:

<!DOCTYPE html> 
<html>
<head>
	<script src="https://maps.googleapis.com/maps/api/js"></script>
</head>
<body>
	<h1>How to create a simple map using jQuery</h1> 
	<div id="MapID"></div>
</body>
</html>

Step2

In this step, we will set the dimensions of our simple map. Using the HTML style attribute, we can change the width and height of our map on the webpage. We can also change the background according to our requirements. The following shows the changes you can make to your code after our second step:

<div id="MapID" style="width:500px; height:400px;background :lightgreen">
</div>

Step3

Now is the time to create the functions to set the map properties. We will add the JavaScript logic to achieve our goal, i.e., create a simple map. We define a JavaScript function named CN(). Let's break down its functionality:


Declaring CustomMapFn object

var CustomMapFn = {
	center: new google.maps.LatLng(28.44294, 77.05581),
	zoom: 19,
	mapTypeId: google.maps.MapTypeId.ROADMAP
};


Firstly we declare a variable named CustomMapFn as an object. This object defines properties related to the customization of the map.

  • In our example, the center property sets the map's center using the LatLng class with latitude 28.44294 and longitude 77.05581.
     
  • Using the zoom property, we set the initial zoom level of the map to 19.
     
  • The mapTypeId property specifies the type of map to be displayed. There are different types, for example, ROADMAPSATELLITE, HYBRID, and TERRAIN.

 

Creating Google Maps object

var map = new google.maps.Map(
	document.getElementById("MapID"),
	CustomMapFn
);


The next step is creating a new Google Maps object by calling a new Map(). The following explains the two parameters:

  1. The first parameter is the HTML element with the ID "MapID," where the map will be rendered. It is obtained using a document.getElementById("MapID").
     
  2. The second parameter is the CustomMapFn object defined earlier, which contains information about the map's configuration.

 

Creating Marker

var marker = new google.maps.Marker({
	position: { lat: 28.44294, lng: 77.05581 },
	map: map
});


At last, a new marker is also created using the Marker() function. The marker is placed on the map with the specified position using latitude 28.44294 and longitude 77.05581. The map property of the marker ensures that the marker is displayed.

Example

Now that we have discussed all the steps of how to create a simple map using jQuery, let's see an example along with the output.
 

Code:

<!DOCTYPE html>
<html>

<head>
	<title>
		Google Maps (Development Purposes)
	</title>

	<script src="https://maps.googleapis.com/maps/api/js?"></script>


	<script>
		function CN() {
			var CustomMapFn = {
				center: new google.maps.LatLng(28.44294, 77.05581),
				zoom: 19,
				mapTypeId: google.maps.MapTypeId.ROADMAP
			};

			var map = new google.maps.Map(
				document.getElementById("MapID"),
				CustomMapFn
			);
			var marker = new google.maps.Marker({
				position: { lat: 28.44294, lng: 77.05581 },
				map: map
			});
		}
	</script>
</head>

<body onload="CN()" style="background-color:orange;">
	<center>
		<h1 style="color:whitesmoke">
			<i>CodingNinjas</i>
		</h1>

		<h3>Simple Google Map using jQuery</h3>

		<div id="MapID" style="width:500px; height:400px;"></div>
	</center>
</body>
</html>

Frequently Asked Questions

Can we create a map using jQuery alone? 

jQuery handles Document Object Model (DOM) manipulation and simplifies JavaScript code, but it is not a map library. So we also need a map library or API along with jQuery to create a map. We can use the Google Maps JavaScript API to generate an API and display the map.

What are the steps to create a map using jQuery?

To create a map using jQuery, generate an HTML file with a container, include the jQuery tag and the required map library or API. After that, write a function to create the map instance and customize its appearance. At last, test it by opening the HTML file in a web browser.

What are the four types of maps?

The four types of maps are ROADMAP, SATELLITE, HYBRID, and TERRAIN. The roadmap shows the street view, the default map type. The satellite types show the satellite image of the area. The hybrid shows the major streets, and the terrain shows the vegetation.

Conclusion

We expect this article was insightful and that you learned something new today. We learned how to create a simple map using jQuery. With the help of jQuery and any map library or API, we can add google maps to our web pages. We can also customize the appearance and functionality of the maps and change the latitude and longitude coordinated according to our needs. We saw the steps of creating a map using jQuery and discussed an example for better understanding.
