How To Insert JavaScript in HTML?
There are two ways to Insert/Connect JavaScript to HTML documents. They are:
Use External JavaScript
You can create external JavaScript and link it to the HTML document. First of all, create a JavaScript file, for example, MyScript.js, and type all the JavaScript code you want. Then goto HTML document and inside <head> section add this code.
<script src="MyScript.js"></script>
Syntax:
<script src="filename.js"></script>
Use JavaScript inside the HTML document
You can also type JavaScript code inside the HTML document using <script></script> tag inside <head> or <body> section. For example:<html>
<head>
</head>
<body>
<button onclick="text()">Click</button>
<button onclick="date()">Date</button>
<p id="demo"></p>
<p id="date"></p>
<script>
function text(){
document.getElementById('demo').innerHTML="IronMan";
}
function date(){
document.getElementById('date').innerHTML=Date();
}
</script>
</body>
</html>
Syntax:
<script>
