how can I pause the executing of a script for a number of seconds

there is a built-in function (sleep()) in php that delays execution of the current script for a specified number of seconds. it can be put anywhere and it will do the job.
here are its explanation:
http://www.w3schools.com/php/func_misc_sleep.asp
http://php.net/manual/en/function.sleep.php

my question: does a such function exist in javascript?

A piece of code would look like:

<html>
    <head>
        <script type="text/javascript">
            function executeAfter(caseVal) {
                switch(caseVal) {
                    case 0:                            // Code to execute before
                        alert("We are going for a sleep of 1 second");
                        setTimeout('executeAfter(1)', 1000);
                        break;
                    case 1:                            // Code to execute after sleep
                        alert("We are woke up");
                        break;
                }
            }
            executeAfter(0);
        </script>
    </head>
</html>

JavaScript generally tries to be non-blocking. There is no sleep() or wait() or anything like that. Functions like setInterval() or setTimeout() can defer execution of a function to a later time, which is useful. However, the current script does not stop executing after those functions are called. It continues running until a separate built-in mechanism, whether it's a timer, a signal, or otherwise, executes the function that was specified in setTimeout().

Nope, and people's attempt with Date and a while() loop are such a bad idea I shouldn't have mentioned them. :P

You can, however, possibly achieve what you want with setInterval() or setTimeout() or a combination.
