You swear right! It sends one block of code to the browser if the
client is MSIE version 5 and another for all other versions. Probably
to work around some bug or another in IE. In short, php writing
javascript, one of my favorite things about net programming. It doesn't
go quite as far as php writing javascript writing html creating styles
with a little dynamically created javascript through an eval or two but
it's still pretty fun.

This script will need to be placed on a server with php to work
properly. It can be altered to function without the need for php.


function parseemail(str) {
str = trim(str);
if (navigator.userAgent.indexOf('MSIE 5.0')>0) {
if(str.search(/\w+@[\w\W]+\.[a-z]{3}/) == -1) {
window.alert("Please enter a valid email address");
return true;
} else {
if(str.search(/^[\w\-\.]+[@][\w\-]+(?:\.[\w\-]+)+$/) == -1) {
window.alert("Please enter a valid email address");
return true;
}
}
}
}

I didn't test the function so it will probably implode, or explode but
at least it gets a little closer to being liked by explorer.
