Create a "Login" anchor link

If you have domino sites that do not explicitly require the user to login, but you want to create a link to let them do so at will, then this may be helpful.....

It makes use of the fact that you can append "&login" to a URL and it will cause the server to authenticate the user.

First, create a link on the form that calls the JavaScript function. You can do this with the following text on the form and mark it as PassThru HTML:

<a href="JavaScript: doLogin()">Login</a>

Now place the following function into your JavaScript library or place it within SCRIPT tags in the document's HEAD.

function doLogin() {
s = document.location.search;

//Check '&Login' not already in URL!
if (s.toLowerCase().indexOf("&login") ==
-1 ) {
//Check that there is a '?Open' part to append to
a = (s=="") ? "?Open&Login" : "&Login";
document.location.href += a;

You can see this in action, as I have placed a little Padlock at the bottom of every page that lets me Login to CodeStore so that I can administer it easily. You won't, however, be able to login as my password is very hard to guess, but you can see the above function's effect on the URL.

Note: Using this may have adverse effects on any paired URL arguments that your forms use. Beware


  1. Login URL for Domino

    I have a site I am working on with a lot of the site available without a login. They want to have the two login fields on the home page so a customer can log in if they want to, then go to a protected area of the site.

    They do not want a custom login page. My alternatives are to create a custom login page using the rest of the home page, or figure a way to pass the username and password thru a URL.

    It looks like your way may work. Do you think I could alter the js to include their username and password then, refresh the page?

    Thanks, DD

      Hi Damian,

      Not sure what you mean exactly, but, yes, you should be able to add the username and password to the URL string using this JavaScript.

    the js given above is very usefull. But when used in frameset, it is not working.

    For this to work in frameset, I use "onClick" instead of "href".

    !-- <a href="" OnClick="JavaScript: doLogin();return false;"> --!

    thanks Jake Howlett
