Optional Parameters in Function

bdichiara · Dec 7, 2006

I have a function :

Code:

function setSource(filename,caption,larger){
  ...

How do i set the default of larger to "false" when the function is used without the variable? in other words, i want the "larger" variable to be optional.

Here's a quick-n-easy example:

Code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "[URL unfurl="true"]http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">[/URL]
<html xmlns="[URL unfurl="true"]http://www.w3.org/1999/xhtml">[/URL]

<head>
<title>test</title>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1" />
<script type="text/javascript">

function blah(a, b) {
   b = (typeof(b) == "undefined") ? false : b;
   alert(b);
}

window.onload = function () {
   blah(1, 2);
   blah(1);
};

</script>
<style type="text/css"></style>
</head>

<body>
</body>
</html>
