How to disable View source and inspect element

Question

How do you disable/ view source/ and /inspect element/, ctrl + u ctrl+shift+I f12 menu bar and right click, also ctrl + s ctrl p ctrl+v ctrl+a ctrl+c and drag select page, please answer all parts that's possible, I prefer to do this will JavaScript array keycodes or html no php or other languages.also I want to block ifram use on my site like somesites such as google. As I understand it is not possible to completely disable view source and inspect element, so I want minification of code and rest of my question answered instead.

Edit:

I solved alot of it myself, I used onkeydown return false to disable all keys, still need the arrays, I disabled inspect element menu bar by forcing browser to window.open I still need right click, however would like to add that I need a custom right click menu, I disabled the possibility to disable Javascript in order to stop the key block by using noscript function redirects. I also still need the drag and select part. I would still like betterways to fix it...maybe even just minify the code or encrypt it. Of anyone needs some of the code I used just reply. I just need to fix it.

Answer 1

It is impossible to prevent the user from inspecting code running on their machine. At the end of the day, the HTML they are getting delivered will be readable in plain text. You can cause a nuisance for most people, but this will not be a valid security measure - chrome extensions will still run, for instance, so if someone is using the NoScript extension it will disable all javascript.

A much better option would be to handle your logic server side, and only send the client the information they need to know/requested.

There are some free javascript obfuscators, such as https://javascriptobfuscator.com/. Please remember that it is not a secure method, though.

I mean no matter how much you block it a person can just type

view-source:https://example.com

Answer 3

document.onkeydown = function(e)
    {
        if(event.keyCode == 123)
        {
            return false;
        }
        if(e.ctrlKey && e.shiftKey && e.keyCode == 'I'.charCodeAt(0))
        {
            return false;
        }
        if(e.ctrlKey && e.shiftKey && e.keyCode == 'J'.charCodeAt(0))
        {
            return false;
        }
        if(e.ctrlKey && e.keyCode == 'U'.charCodeAt(0))
        {
            return false;
        }
    if(e.ctrlKey && e.shiftKey && e.keyCode == 'C'.charCodeAt(0))
    {
      return false;
    }
    }

e is a keyboard event. e.[key] returnes true if key pressed.

If document.onkeydown returns false, key doesn't count.

This programm seeing if code view combination pressed and returning false.

Example. if ctrl, shift and 'J' pressed - return false.

Bump

To the people saying it isn't possible, how would you recon this website managed to do so?

The following website disabled, view source, right click and the dev console.

I am genuinely interested.

Edit: all input from keyboard is disabled, but by adding "view-source:" before the httpps:// to the url to become:

view-source:https://www.techgyd.com/contact-facebook-directly/6579/

makes me able to see.

If you would like to know how they did that then take a look at their JS, raw copy/paste:

<script type="text/javascript">
        //<![CDATA[
        var show_msg = '';
        if (show_msg !== '0') {
            var options = {view_src: "View Source is disabled!", inspect_elem: "Inspect Element is disabled!", right_click: "Right click is disabled!", copy_cut_paste_content: "Cut/Copy/Paste is disabled!", image_drop: "Image Drag-n-Drop is disabled!" }
        } else {
            var options = '';
        }

        function nocontextmenu(e) { return false; }
        document.oncontextmenu = nocontextmenu;
        document.ondragstart = function() { return false;}

        document.onmousedown = function (event) {
            event = (event || window.event);
            if (event.keyCode === 123) {
                if (show_msg !== '0') {show_toast('inspect_elem');}
                return false;
            }
        }
        document.onkeydown = function (event) {
            event = (event || window.event);
            //alert(event.keyCode);   return false;
            if (event.keyCode === 123 ||
                    event.ctrlKey && event.shiftKey && event.keyCode === 73 ||
                    event.ctrlKey && event.shiftKey && event.keyCode === 75) {
                if (show_msg !== '0') {show_toast('inspect_elem');}
                return false;
            }
            if (event.ctrlKey && event.keyCode === 85) {
                if (show_msg !== '0') {show_toast('view_src');}
                return false;
            }
        }
        function addMultiEventListener(element, eventNames, listener) {
            var events = eventNames.split(' ');
            for (var i = 0, iLen = events.length; i < iLen; i++) {
                element.addEventListener(events[i], function (e) {
                    e.preventDefault();
                    if (show_msg !== '0') {
                        show_toast(listener);
                    }
                });
            }
        }
        addMultiEventListener(document, 'contextmenu', 'right_click');
        addMultiEventListener(document, 'cut copy paste print', 'copy_cut_paste_content');
        addMultiEventListener(document, 'drag drop', 'image_drop');
        function show_toast(text) {
            var x = document.getElementById("amm_drcfw_toast_msg");
            x.innerHTML = eval('options.' + text);
            x.className = "show";
            setTimeout(function () {
                x.className = x.className.replace("show", "")
            }, 3000);
        }
    //]]>
    </script>

or just look from line 86 I hope it helps
