Hi i want to stop user changing my scripts from console of browser.
For example: In html,if i have div like below
<div id="demo">
Hi..
</div>
and jQuery
$('#demo').hide();
But still user can do inspect element of this page and they change script or coding from console and they can view the div which has ID demo.So please tell me how to stop user changing my code or even though if they change it should not show the div.
Here you could read an article with some useful words: How to hide a JS Code
Also, you could use an obfuscation
You just need to realise that you can't hide a JS code from user, because browser should download it and execute. If you want to encrypt it you should send a pass to browser which user'll get too.
Just imagine: I'm telling you 1 and you should tell me the same. What would you tell me if I'd told you 2 ?
And ... here it is ... problem of all programmers. All programmers want hide their own code : ). Just ... believe me. It is.
One more suggestion is just to try this: Online Obfuscator
If you want to do this with a PHP code, try this:
// action.php
<?php
if ( !isset($_POST['show']) ) {
die('HACKER !');
} else {
echo '
<html>
<head>
<title>Main Page</title>
<body>
<div id="demo">DEMO</div>
<br>
<form action="action.php">
<input name="show" style="display: none;">
<input type="submit" value="Try me !"/>
</form>
</body>
</html>';
}
?>
These files should be in same folder.
// index.html
<html>
<head>
<title>Main Page</title>
</head>
<body>
<form action="action.php">
<input name="show" style="display: none;">
<input type="submit" value="Try me !"/>
</form>
</body>
</html>
Good luck : )
Once your page is sent to user, you can't prevent him to do anything. Even with a minified js, he'll be able to force a display on the element. All you can do is hiding it php side before sending page
For exemple :
<?php
session_start();
if (!empty($_GET['demo']) && $_GET['demo'] == "whatever") $_SESSION['show_demo'] = true;
?>
<?php if(isset($_SESSION['show_demo']) && $_SESSION['show_demo'] == true): ?>
<div id="demo">
Hello World
</div>
<?php endif;?>
<a href="?demo=whatever">Click here to show demo</a>
I was recently doing research on this subject. It might not be the optimal solution but php has a built in function called htmlspecialchars
See this for further explanation:
http://php.net/manual/en/function.htmlspecialchars.php
Offcourse your tag says php, but i don't see any php code at the moment in your current code. What i can Also recommend is these 2 links for achieving the same effect with different programming languages:

Hope you achieve your goal further. Good luck
