HTML5 & JavaScript Contact Manager

In this video tutorial I’ll demonstrate how to create contact input to submit contact info into JavaScript contact array and how to delete it.

Here is the source code:

<!DOCTYPE html>
<html>
	<head>
		<title>ZK Tutorials</title>
	</head>
	<body>
		<h1>HTML5 & JavaScript Contact Manager</h1>
		<input placeholder="Name" id="name"><br>
		<input placeholder="City" id="city"><br>
		<button onclick="add()">Add</button>
		
		<div id="contacts"></div>
		
		<script>
			var contacts = [];
			
			function add(){
				var name = document.getElementById("name").value;
				var city = document.getElementById("city").value;
				var newContact = {
					newName : name,
					newCity : city
				}
				contacts.push(newContact);
				
				updateDiv();
				
				document.getElementById("name").value = "";
				document.getElementById("city").value = "";
				
			}
			
			function updateDiv(){
				var tempContent = "";
				for(var i = 0; i < contacts.length; i++){
					
					tempContent += "<p>Name : " + contacts[i].newName + "<br>City : " + contacts[i].newCity + "<br><span onclick='del(" + i +")'>[del]</span></p>";
				}
				
				document.getElementById("contacts").innerHTML = tempContent;
			}
			
			function del(i){
				contacts.splice(i, 1);
				updateDiv();
			}
		</script>
	</body>
</html>
