JavaScript Funcitons
- A JavaScript function contains some code that will be executed only by an event or by a call to that function
> To keep the browser from executing a script as soon as the page is loaded, you can write your script as a function
- You may call a function from anywhere within the page (or even from other pages if the function is embedded in an external .js file)
- Functions can be defined either <head> or <body> section
> As a convention, they are typically defined in the <head> selection
Example: JavaScript Function
<html>
<html>
<head>
<script type="text/javascript">
// If alert("Hello world!!") below had not been written within a
// function, it would have been executed as soon as the page gets loaded.
function displaymessage() {
alert("Hello World")
}
</script>
</head>
<body>
<form>
<input type="button" value="Click me!" onclick="displaymessage()" >
</form>
</body>
</html>
