#19302 — Pass username to a new html file

I use function GotrisLogin in Login.html to display a page with username and 
password.
If succsessful login I display a new page by  using window.location.href = 
"Obstacle.html";
This works good.
Now in the new html page "Obstacle.html"  I need the entered username from 
login.html.

How can I pass the entered username from login.html to Obstacle.html ?

function GotrisLogin()
        {
            gotris_login($('#txtUserName').val(), $('#txtPassWord').val(), 
function (data, textStatus, jqXHR)
            {
                //If successful login set cookie and switch html page
                if (IsOkMessageShort(data.dsError))
                {
                  window.location.href = "Hinder.html";
                }
            });
        }

You're leaving out a lot of information here... As a shot in the dark,
it looks like you're authenticating against a server, but at least some
of your HTML documents are completely static. That's an uncommon
solution, and you'll likely run into the same question (how to
communicate between static documents) throughout the rest of the
application.

If this is how your project works, your main options would be URL
parameters, asking the server, and maybe using frames. Cookies and
session storage might be options, but are unreliable/unavailable when
your HTML files are loaded directly from the local file system (depends
on the browser).

Regarding your example, if you want to pass data to Obstacle.html, it
would be a start to actually load Obstacle.html instead of Hinder.html.

login.htm:

  <form method="get" action="obstacle.html">
   <input type="password" name="password">
   <input type="submit">
  </form>

obstacle.htm:
 
  alert(window.location.search);

But the level of security is low because the URL of the protected page is present in the page source itself.

It would be a lot safer to perform your redirect based upon the value of the password. Eg. use 'Hinder' as a password, and then redirect to [password].html, after a 404-check with XmlHttpRequest.

Hope this helps,
