"switch ... case" Statement Example
This section provides a JavaScript tutorial example showing how to write a 'switch ... case' statement.
To help you understand how "switch ... case" statements work, I wrote the following the JavaScript tutorial example, Switch_Case_Statements.html:

<body>
<pre>
<script type="text/javascript">
// Switch statement with a numeric expression
var week_day = 4;
var day, open_hours;
switch (week_day) {
case 0:
day = "Sunday";
open_hours = "closed";
break;
case 1:
case 2:
case 3:
case 4:
case 5:
day = "a weekday";
open_hours = "open from 9:00am to 9:00pm";
break;
case 6:
day = "unknown";
open_hours = "open from 9:00am to 5:00pm";
break;
default:
day = "unknown"
open_hours = "undefined";
}
document.write('\n');
document.write("Today is " + day + ".\n");
document.write("The library is " + open_hours + ".\n");
</script>
</pre>
</body>
</html>
The output of this sample JavaScript is:
Today is a weekday. The library is open from 9:00am to 9:00pm.
