Getting an HTML H1 value to JavaScript variable?

Javascript Web Development Object Oriented Programming

To get the value of H1 to JavaScript variable, you can use −

document.getElementById().innerHTML.

Let’s say the following is our H1 heading −

<h1 id="demo"> This is the demo program of JavaScript ........</h1>

Now, let’s get the H1 value using the below code −

Example

Live Demo

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initialscale=1.0">
<title>Document</title>
<link rel="stylesheet"href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css">
<script src="https://code.jquery.com/jquery-1.12.4.js"></script>
<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>
</head>
<body>
<h1 id="demo"> This is the demo program of JavaScript ........</h1>
<script>
   var data=document.getElementById('demo').innerHTML;
   console.log("The data is="+data);
</script>
</body>
</html>

To run the above program, save the file name “anyName.html(index.html)” and right click on the file. Select the option “Open with Live Server” in VS Code editor.
