[Help] JavaScript Encryption Script

BobbyDouglas · #1 02-Mar-2004, 10:13

I am trying to modify Walt's script that he posted in reply to my encryption method.

I want to allow the user to Copy the text to the clipboard, or manually select and copy it.

The problem I am having right now is with the copy button code.
I am trying to insert it, but it isn't quite working out for me.

I am trying to display it in this part of my email.js file:

Code:

    Encrypt(value);
    numArray++;
    document.write ("<table border='0' cellpadding='3' width='80%' align='center'>");
    document.write ("    <form action='email_encryption.php' method='get' name='emailencrypt'>");
    document.write ("    <tr><td valign='bottom'>");
    document.write ("            <input type='submit' class='input' name='submit' value='Submit' />");
    document.write ("		 <script src='copy.js'><\/script>");
    document.write ("        </td>");
    document.write ("        <td>");
    document.write ("            <i>Enter info to encode</i> <br />");
    document.write ("            <input type='text' class='input' name='encode' size='55' value='");
    document.write (valueDisplay);
    document.write ("' />&nbsp;&nbsp;");
    document.write ("            <input type='text' class='input' name='numarray' size='3' value='");
    document.write (numArray);
    document.write ("' />");
    document.write ("        </td>");
    document.write ("    </tr>");
    document.write ("    </form>");
    document.write ("    <tr><td></td>");
    document.write ("        <td valign='bottom'>");
    document.write ("        <form name='encryptedemail'>");
    document.write ("            <textarea class='input' name='encrypted' rows='" + outLines + "' cols='64'>");
    document.write (javEncrypted);
    document.write ("</textarea>");
    document.write ("        </form>");
    document.write ("        </td>");
    document.write ("    </tr>");
    document.write ("</table>");

You can see the latest versions of this at:
mrbobdouglas[dot]com/testing/email.js
mrbobdouglas[dot]com/testing/email_encryption.php
mrbobdouglas[dot]com/testing/copy.js

I include the external email.js file, and call the function to display the text boxes ect by:

Code:

  <script>
	<!--
	 ProcessEncryption();
	// -->
  </script>

Not sure where to go from here. :eek2

Thanks!

Since by default my code already allows manual select and copy, that obviously does not need to be added.

As for a button to accomplish this task, I haven't a clue.

- The easier it is, the better it is

Yes someone can manually click inside the box and scroll down, then right-click and copy it. Or they can click one button.

I'm a keyboard user

-- Ctrl-A Ctrl-C and done. No scroll, no right-click. But that's just me.

If I find anything about the button, I'll let you know.

I also use that, but others might not.

If you take a look again at http://www.mrbobdouglas.com/testing/...encryption.php you will see a few more set of errors.

I get a different error message this time though. Complaining about
1st one:
Line: 32
Char: 55
Error: Unterminated string constant
Code: 0

2nd one:
Line: 31
Char: 3
Error: Object expected
Code: 0

All I see is a gray background with the instructions. I've added the page source below. I'm using NS7 as my browser. The javascript console gave 2 errors:

Code:

Error: unterminated string literal
Source File: http://www.mrbobdouglas.com/testing/email.js
Line: 31, Column: 34
Source Code:
        str = str.substr(0,i) + """ + str.substr(i+1);
----------------------------------------------
Error: ProcessEncryption is not defined
Source File: http://www.mrbobdouglas.com/testing/...encryption.php
Line: 35

Obviously """ is not a double quote character. Try """" or "\""

Hope that's a help.

Code:

<html>
<head>
<style>
td{font-family:Tahoma;font-size:11px;color:#ffffff}
    </style>
<link   rel     =  STYLESHEET
                href    =" ../scripts/main.css"
                Type    =" text/css"    >
                
<script src="email.js"
        type="text/javascript"></script>

<script language="JavaScript">
<!--
function highlightmetasearch() {
document.emailencrypt.encrypted.select(); document.emailencrypt.encrypted.focus();
}
function copymetasearch() {
highlightmetasearch();
textRange = document.emailencrypt.encrypted.createTextRange();
textRange.execCommand("RemoveFormat");
textRange.execCommand("Copy");
alert("This post has been copied to your clipboard.");
   }
// -->
</SCRIPT>
</head>

<body>
Please follow the following instructions for this method:
<br>
  <script>
	<!--
	 ProcessEncryption();
	// -->
  </script>

<p>Copy the generated info below and place it in the source code to display the text entered in the first box. Each encrypted piece placed on the same webpage should have a different array encryption name as shown by the var byX = new Array line where X is a numerical value. The numbered box above shows the next array to be created. The value may be modified if needed.</p>
</body>
</html>
