JavaScript Function Literals
The Function Literals
JavaScript 1.2 introduces the concept of function literals which is another new way of defining functions. A function literal is an expression that defines an unnamed function. The syntax for a function literal is much like a function statement, except that it is used as an expression rather than a statement and no function name is required.
<script type = "text/javascript">
var variablename = function(Argument List) {
Function Body
};
</script>
<html>
<head>
<script type = "text/javascript">
var func = function(x,y) {
return x*y
};
function secondFunction() {
var result;
result = func(10,20);
document.write ( result );
}
</script>
</head>
<body>
<p>Click the following button to call the function</p>
<form>
<input type = "button" onclick = "secondFunction()" value = "Call Function">
</form>
<p>Use different parameters inside the function and then try...</p>
</body>
</html>
