setfocus after alert in javascript

[amy]

I have a text box, once the user input the value in, I do a validate
to the input, if it's invalid, then do a alert and set focus to this
control.

The alert displays, but the set focus doesn't work.Here is the client
side javascript code,

if (run!="" && IsNumber(run)==false && decimalinputvalid(run,2)==0 )
{
alert('This field only allows the entry of a maximum of 2 decimal
places. Please re-enter a correct value.');
//set focus
document.papercaltbl.printorder.focus();
}

Please give some advise. Thanks in advance.

This has nothing to do with ASP, serverside coding.

Please see a clientside js NG.
