guide the user

JavaScript2/week3/script.js

Line 28 in 5b0e127

//do sth

here I advice you to add alert, to tell the user what is wrong and what he should input, try this:
if (xmlHttp.readyState == 4 && xmlHttp.status == 404)
alert('tell the user what should he do');

eah this is probably better, I tried to do it before but it didnt work out because I forgot the
if (xmlHttp.readyState == 4 && xmlHttp.status == 404)
That's why it kept on giving alerts each time even if it's a good request.

Anyways thanks alot for the advice I''ll try and implement it in my code
