Replace your js by this :
________________________
var user = prompt("What is your name?");

while(user == null || user == ""){

user = prompt("gimme your name I said !");

}

alert( "Hello "+user+ " ,Welcome");

Beware ! this is a stalker code, it won't let you through unless you have typed a name xD
