setFocus(document.getElementById("tf1"));
return;
}

if(document.getElementById("tf2").value=="")

Click to expand...

Sequence of the events:
1.tf1 lost focus.
2.tf2 got focus.
3.alert that was caused by tf1 onblur event is shown up (tf2 lost
focus).
4.alert that was caused by tf2 onblur event is shown up.
5.tf1 got focus.

You can avoid it in this way:

function checkfun(sender)
{
if(sender.value=="")
{
alert("The field is empty");
setFocus(sender);
}
}

TF1: <input id="tf1" type="text" value="" onblur="checkfun(this)"/>
TF2: <input id="tf2" type="text" value="tf2" onblur="checkfun(this)"/>
