A simple solution.
if (input.value == "") {
alert("Please enter a user name");
return false;
}
if (input.value.indexOf(";")!=-1) {
alert("The user name can not contain a ';' character");
return false;
}
if (input.value.indexOf(" ")!=-1) {
alert("The user name can not contain a space");
return false;
}
You can use the search() function of the String object with a reg exp but
not all browsers support it.
