i just want to ask why this set of functions doesnt work in ff but perfectly works in ie:

document.myform.fname.focus();
document.myform.fname.select();

It does work in Firefox, actually. Here's an example:

http://www.dynamicdrive.com/style/cs...css-tabs-menu/

You've probably got some error in your code somewhere. Where's the page you're working on?

actually this is my code of doing it:
function chkfname(n){
fn=n.value;
if(fn.length !=0){
if(isNaN(fn)==false){
alert('Only alpha chars are allowed...');
document.myform.fname.focus();
document.myform.fname.select();
}else{
if(fn.length >15){ // check the number of chars...
s=fn.slice(1,15);
document.myform.fname.value=s;
alert('allowed char is only 15');
document.myform.lname.focus();
}
}
}
}


...on ie, upon click ok on the alert it will go to fname txtbox. however if i use ff, it will go to the next. is there any problem with my code?

This is deliberate behaviour to prevent mis-operation.
If this function is triggered by an onblur handler, clicking the OK will refocus the input, which will them immediately lose focus because the button is still down. This can cause endless loops.

Avoid the combination alerting on blur and refocusing the input.
