JavaScript Where to Insert

For inserting JavaScript in Html document we use <script> tag in document. We can insert JavaScript in <Head> and <Body> section of Html document. We can also also use External JavaScript In our document.

  • For using External document we use <script> tag with "source" attribute of JavaScript.
  • External JavaScript save with .Js external. (For example Myfile.Js.
  • For using external JavaScript source path must be require.

Using JavaScript in <Head> section.

<html>

<head>

    <script type="text/jscript">

        function Myfunction() {

            document.write("JavaScript in HEad section");

      

    </script>

</head>

<body>

    <button onclick="Myfunction()">

        click me</button>

</body>

</html>

 

Using JavaScript in <body> section.

 

<html>

<body>

    <button type="button" onclick="Myfun()">

        Click me</button>

    <script type="text/javascript">

        function Myfun() {

            document.write("JavaScript in body section");

        }

</script>

</body>

</html>

 

Using External JavaScript //In this example MyDoc.Js is external JavaScropt file.

 

<html>

<head>

    <script type="text/javascript" src="MyDoc.Js"></script>

</head>

<body>

</body>

</html>
