Setting up quick and dirty (temporary) password protection using JavaScript

**pbmods** · Aug 7 '07, 10:36 PM

Heya, Death. Welcome to TSDN!

Phew, that's a project! And unfortunately, you're asking about this in the wrong forum.

JavaScript can't do login stuff like that. You have to take care of that stuff on the server-side using a language such as PHP.

PS Changed thread title to better describe the problem (did you know that threads whose titles contain phrases such as, 'need help' actually get FEWER responses?).

Heya, Death.

Even easier than trying to do it in JavaScript, simply add this statement to the top of your page:

[code=php]
<?php
if($_GET['password'] != 'thepasswordgoe shere')
{
exit('You didn\'t say the magic word.');
}
?>
[/code]

Here is a javascript function that will check your password if your website doesn't support php.

Code:

<script language="javascript" type="text/javascript">
 function check_entry()
 {
  if(document.login.password.value == "yourpassword")
  {
   return true;
  }
  return false;
 }
</script>

<form name="login" action="location" onsubmit="return check_entry();">
 <input type="password" name="password">
 <input type="submit" value="Login">
</form>

Please be aware that if someone were to look at the source code, they could see the password and where a correct password would take you.

Heya, Death.

You posted a similar question in the PHP forum, so I assumed that a PHP solution would be OK.

The issue with a JavaScript solution, as johnhjohn pointed out, is that ultimately, you are presenting the password to the User in plaintext if he knows where to look.

yes and no i want this to be a simple one just a password but i want the other one a username and password that i can look at and edit its for a game im going to make so its for my players accounts and would you have a script for blocking viewers from seeing the script and also im trying to put an image on it this is what im tryin

1 <html>
2 <embed src="C:\Documen ts and Settings\Owner\ My Documents\My Pictures\imagen ame">
3</html>

that just gives me a box i tried putting in width and height but it was fruitless i know im doing something wrong so if you could help out on this to it would be great.

Thanks man

the script works great most of the poeple that know about my site dont know how to view source so its great but as i said before if you guys know how to block people from seeing that would be great just in case

**johnhjohn** · Aug 8 '07, 10:48 PM

There isn't a way to block the script from view, since it isn't a server-side script. And for the image, use the <img> tag:

Code:

<img src="C:\Documents and Settings\Owner\My Documents\My Pictures\imagename"></img>

Hope this helps.
