Howdy

I've got a little JavaScript form that I would like to figure out. Was hoping you guys could help me with that.

<script language="JavaScript">
<!--
x=prompt('Yay\n Enter password:',' ');
x=new String(x + " z");
var y = "1338";
var z = "1";
var f = "y - z";
if (x == f) {
location.href = "?page=soccer&pw=" + x;
}
else {
location.href = "blank.htm";
}
//-->
</script>

I can't seem to understand this. But I don't want access just to get passed it, I also want to learn how that works, so if you could explain a bit about how the code works, that would be great! Thanks

Btw, I'm Norwegian if there was any Norwegians here who finds it easier to write in our own language (if thats permitted)

I'd suggest inserting a few alert statements that show you the variable values, or, of course, a JavaScript debugger like Venkman (which is free for Firefox).

Posting in Norwegian is not allowed, since the JavaRanch staff do not speak that language.

Well, actually, I found the answer myself But how about this one?

<script language="JavaScript">
<!--
function test(passwd) {
y=String.fromCharCode(115) + String.fromCharCode(101) + String.fromCharCode(passwd.substring(0,1)*11) + String.fromCharCode(114) + String.fromCharCode(101) + String.fromCharCode((passwd.substring(0,1)*13)-1);
if (passwd.substring(1,7) == y) {
location.href = "?page=level17&pw=" + passwd;
}
else {
location.href = "levels/error.php";
}
}
//-->
</script>
