Passing variable to a form action script

Question

I'm new with javascript, can someon please point me in the right direction to accomplish the following code ?

I have a page to automatically log me in into websites for work, but i'm searching a way to have the login credentials being either read from a ini file, or just by using document.write so its easer to pass and change these credentials in my HTML that hase a lot of these buttons.

<script language="javascript">


var username = "firstusername";
var password = "firstpassword";


<!-- link -->
<form action="***************" method="post"  target="_blank">
<p>
<input type="hidden" name="HdnCallingProgram" value="login"/>
<input type="hidden" name="HdnAction" value="Login"/>
<input type="hidden" name="txtUserId" value="document.write(username)"/>
<input type="hidden" name="txtPassword" value="document.write(password)"/>
<input type="hidden" name="chkRemember" value="1"/>
<a class="button1" title="Bij fout aanmelden : gebruik browser back button en terug op knop klikken"  onclick="parentNode.parentNode.submit()">Cafe</a>
</p>
</form>


</script>

Thanks for reading this!

<script type="text/javascript">
var username = "firstusername";
var password = "firstpassword";

document.getElementById('txtUserId').value = username;

Thanks alot, that works perfect!, i do have a lot of elementid's in my page, does anyone know if this could be done with a readfrom file aswell?

Of course yes, but I don't know what file are you talking about. With ajax you can read file from server and parse it in script...

Oke, so the file i was refering to should be stored localy next to my html page, i'm hoping there could be a easer way to just "insert" variables into my code so the username and passwords could be read and inserted. Again your answer did the trick perfectly another way could save me lots of time :)

"stored localy" - It can be a little problem, because security reasons Ajax not working at localhost, but still you can use JS file. Add this, before script: <script type="text/javascript" src="file_to_read.js"></script> and in this file: window.storedData = {username: "firstusername", password: "firstpassword"}. To read data write: document.getElementById('txtUserId').value = storedData.username;
