如何阻止用户从浏览器控制台更改脚本[关闭]

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 : )
