VBScript Where To

 

Where to put the VBScript

Scripts in a page will be executed immediately while the page loads into the browser. This is not always what we want. Sometimes we want to execute a script when a page loads, other times when a user trigger an event.

Scripts in the head section: Scripts to be executed when they are called or when an event is triggered, goes in the head section. When you place a script in the head section you will assure that the script is loaded before anyone use it.

<html>

<head>

<script language="VBScript">

some statements

</script>

</head>

Scripts in the body section: Scripts to be executed when the page loads, goes in the body section. When you place a script in the body section it generates the content of the page.

<html>

<head>

</head>

<body>

<script language="VBScript">

some statements

</script>

</body>

Scripts in both the body and the head section: You can place an unlimited number of scripts in your document, so you can have scripts in both the body and the head section.

<html>

<head>

<script language="VBScript">

some statements

</script>

</head>

<body>

<script language="VBScript">

some statements

</script>

</body>

EXAMPLES

1. Script that contains functions goes in the head section of the document, then we can be sure

that the script is loaded before the function is called.

Coding

<html>

<head>

<script language="VBScript">

function headsection()

msgbox("A function is usually placed in the head section")

end function

</script>

</head>

<body>

<form>

<input type="button" onclick="headsection()" value="Execute script">

</form>

</body>

</html>
