How to create javascript delay function

Question

I have a javascript file  and in several places I want to add a small delay  so the script would reach that point  wait 3 seconds  and then continue with the rest of the code  The best way that I thought of doing this was to create a function  which I could call from anywhere in the script   function startDelay lengthOfDelay      code to make it delay for lengthOfDelay amount of time     However  I can not find any way to implement the code to make it wait  I had a look at setTimeout  but you needed to hard code the function into it  which made it no good for me   Is there any way that I can get the script to juct pause for a few seconds  I have no problem with the UI freezing whilst the code is paused   If not  is there a way that I could use the PHP sleep   to achieve this   I know that PHP is server side and Javascript is client side  but maybe there is a way that I have not heard of

You can create a delay using the following example

setInterval(function(){alert("Hello")},3000);

Replace 3000 with # of milliseconds

You can place the content of what you want executed inside the function.

You do not need to use an anonymous function with setTimeout  You can do something like this   setTimeout doSomething  3000    function doSomething          do whatever you want here

Ah yes  Welcome to Asynchronous execution   Basically  pausing a script would cause the browser and page to become unresponsive for 3 seconds  This is horrible for web apps  and so isn t supported   Instead  you have to think  event-based   Use setTimeout to call a function after a certain amount of time  which will continue to run the JavaScript on the page during that time
