how to make a sleep in javascript?

Question

Does anyone know how can I make a sleep in javascript before next line been read by the system?

example:

    1 var chkResult = Validation();
    2 //sleep here for for 10 sec before the next line been read    
    3   
    4 document.getElementById('abc').innerHTML = chkResult;

For this example, how can I make the javascript sleep/wait in line 2 for 10 sec before it continues to read line 4? I had tried setTimeout('', 10000); but it's seems not working for me still...

Answer 1

I Have the Hat has given the right hint. Use the setTimeout method to execute your forth line code after 10 seconds:

var chkResult = Validation();
var timeout = window.setTimeout(function() {
    document.getElementById('abc').innerHTML = chkResult;
}, 10000);

Storing the timeout ID in a variable can be handy if you want to clear a timeout.

Answer 2

Try

setTimeout(function() { return true; }, 10000);

The first argument expects a function. This is from memory; I haven't tested it.

Edit: What Gumbo said... late here... not sure what I was thinking.
