Thanks that worked beautifully!
Now how would I go about adding another text input above the password input and have them both write to the same cookie?

**jscheuer1** · 02-12-2007, 04:32 AM

My thinking was that rather than rewrite other saving scripts into this one, this script could be used along with pretty much any other script that does that sort of thing (saves text fields or whatever).

**trippin** · 02-12-2007, 08:01 AM

So what is the difference between this script and the one here which enables it to work???

The main difference is that I wrote the script in this thread from scratch with the specific purpose in mind of saving the password. The other script you are referencing was written by someone else, I believe specifically to save text field values.

The reason I asked this is because I have been messin around with your code and can't get a text input to write to this same cookie. I've tried using it along with the Form Recall Script II. When I do this only the password is saved by your script.

I am using a form like so:

HTML Code:

<form name="manlog" action="/">ID: 
<input type="text" name="login"><BR>PW: 
<input type="password" name="passwd"><br>
Save Login?<input type="checkbox" id="persistbox"><br>
<input type="submit" value="Login">
</form>

Also I noticed that the status of the checkbox was not being recorded to cookie so when I leave the site and come back the cookie is erased because the checkbox becomes empty.

**trippin** · 02-12-2007, 01:11 PM

I did it! This script will save ALL fields or SPECIFIC fields in the form you specify and write them to a cookie. I had a lot of problems with trying to write the password value to cookie but not anymore.

<script src="logincookie.js" type="text/javascript"></script>
</head>
<body onload="recoverInputs(document.forms.manlog,retrieveCookie('y_login'),true);">
<form name="manlog" action="/">ID: 
<input type="text" name="login"><BR>PW: 
<input type="password" name="passwd"><br>
Save Login?<input type="checkbox" id="remember"><br>
<input type="reset" name="g">

<input type="button" value="Save" onclick="rememberme()">
<input type="button" value="Recover" onclick="recoverInputs(this.form,retrieveCookie('y_login'),true);">
</form>
