Hi Max,

You're welcome.

Thanks!

I didn't know there was a function like that.

Hi Max,

Sorry for the delay. I can blame the system being down, but...
In my original post, I thought you were attempting to encrypt an entire message.
If you are trying to encode for email/cgi, this is all you need:
endcodedMsg = escape(document.URLencode.message.value);
decoding would be:
decodedMsg = unescape(encodedMsg);

I guess I didn't delete it... I found it.

I started working on it again this morning, but I'm a bit fried and can't find what's wrong. It doesn't work right now with the comments in, and it needs to work with them out (so the whole script can function).

<html>
<body>

&lt;script language=javascript&gt;
<!--

Character = new Array
Character[0] = " "
Character[1] = "/"
Character[2] = "?"

Encoded = new Array
Encoded[0] = "%20"
Encoded[1] = "%2F"
Encoded[2] = "%3F"

function Encode() {

msg = URLencode.message.value

if (msg == "") {
alert("There is nothing to encode.\nThe text box is empty.")
return false
}

for (i=0; i<2; i++) {
CheckFor(msg, i)
} //End for (i=0; i<2; i++)

document.URLencode.message.value = msg
} //End Encode()


function CheckFor(msg, x) {

if (msg.indexOf(Character(x)) > -1) {
/*
Replace(msg, x, msg.indexOf(Character(x)))
*/
} //End if (msg.indexOf(Character(x))
else {
return true
} //End if (msg.indexOf(Character(x)) > -1)

} //End function CheckFor(msg, x)

/*
function Replace(msg, y, pos) {

if (pos == "1") {
before = ""
after = msg.substring(pos+1, msg.length)
}

if (pos == msg.length) {
before = msg.substring(0, pos-1)
after= ""
}

if ((pos != "0") && (pos != msg.length)) {
before = msg.substring(0,pos-1)
after = msg.substring(pos+1, msg.length)
}

msg = before + "Encoded(y)" + after

CheckFor(msg, y) //Any more?
} //End function Replace(msg, y, pos)
*/

//-->
&lt;/script&gt;

<form name=URLencode onSubmit="Encode(); return false;">
<input name=message type=text size=40>
<input type=button value="Encode It!" onClick="Encode()">
</form>

</body>
</html>

I don't care if anyone see's the code... I'm trying to make a client side URL-encoder.

could I do something like...

String = "AaBxCcDc"  // will come from a text box
num = String.indexOf(x)

before = String.substring(0, num-1)
after = String.substring(num+1, String.length)

form.textbox.value = before + "b" + after

I had a more complex (but incomplete) version written earlier this week, but then I deleted it thinking that there HAD TO BE an easier way.

Hi Max,

string.indexOf(searchStr) provides the starting index of the string you are looking for.

Insofar as encoding: I don't recall of any such javascript methods, so you would have to write your own. The simpliest one I can think of is to up the character that is -- if character equals A then replace it with B. However, that means that the encrypting algorythm would be visible to anyone who decided to rightClick.
My recommendation: use perl or some other cgi friendly language.
