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 /         


        

Answer 1

    1 var chkResult = Validation();
    2 alert("wait ten seconds, then press ok");
    3       
    4 document.getElementById('abc').innerHTML = chkResult;

The preceeding code delegates the sleep task to a parallel processor. This is a little messy because you have to use a DSL for this style of threading.
