Check Forms Authentication Status Using Only JavaScript?

Jul 20, 2010

The reason i need to do this is because of Facebook Connect - which is another story, so i'll save you the drama for that. =) Anyway, i have this function that runs on window.onload:

function userAuth() {
SomeFunctionWhichGetsFacebookCookes();
if (!loggedInUsingFormsAuth && loggedInViaFacebook) {
window.location.reload(); // refresh page, so i can perform auto-login
}
}

So, i need help in getting the flag "loggedInUsingFormsAuth". I dont care what is in the cookie, just need to know if the current user is authenticated. Why am i doing this? Well, on window load, if the user is logged into Facebook but not on my website (according to the Forms Authentication cookie), i want to reload the page - which allows my ASP.NET website to read the Facebook cookies in the HttpContext and log the user in. I need to do this in JavaScript, because i dont have the Facebook cookies until i call "SomeFunctionWhichGetsFacebookCookies" - which can only be done in JavaScript.

So, how can i work out if the current user is authenticated via JavaScript? Do i have to manually traverse through the cookies, find the one i want, and inspect it? Is this a safe thing to do? Or should i alternatively write out the flag to the client from the server using RegisterClientScript?

Javascript - How To Check Whether A Certain Text Box Exists In A Page

Feb 9, 2010

Suppose I have a master page where I have written some javascript to access the value of a particular asp.net text box, which resides in one of its content pages, but not in all the pages. This piece of javascript code can't be moved to that particular content page because of some restrictions.

Now I need a way to determine whether or not that text box exists in the page, which will imply that the content page containing that text box has been loaded.

How I can I do that in javascript?

Javascript - Check If A File Exist In The Server?

Feb 15, 2010

string jSFile = ResolveUrl("~/MyProject/JavaScripts/dir/test.js");
if (!System.IO.File.Exists(jSFile))
{
...
}

This code doesn't work and I guess it's the jSFile that doesn't work well with the IO.File.Exists but I know the jSFile has a valid path because when I use few line later

Page.ClientScript.RegisterClientScriptInclude("myfile",jSFile);

it does attach the JavaScript file to the ASPX and all work fine.
