You simply can't.

Code inspectors are designed for debugging HTML and JavaScript. They do so by showing the live DOM object of the web page. That means it reveals HTML code of everything you see on the page, even if they're generated by JavaScript. Some inspectors even shows the code inside Iframes.

How about some JavaScript to disable keyboard / mouse interaction...

There are some JavaScript tricks to disable some keyboard, mouse interaction on the page. But there always are work around to those tricks. For instance, you can use the browser top menu to enable DOM inspector without a problem.

Try theses:

They are outside the control of JavaScript.

Big Picture

Think about this:

  1. Everything on a web page is rendered by the browser, so they are of a lower abstraction level than your JavaScript. They are "guarding all the doors and holding all the keys".
  2. Browsers want web sites to properly work on them or their users would despise them.
  3. As a result, browsers want to expose the lower level ticks of everything to the web developers with tools like code inspectors.

Basically, browsers are god to your JavaScript. And they want to grant the web developer super power with code inspectors. Even if your trick works for a while, the browsers would want to undo it in the future.

You're waging war against god and you're doomed to fail.

Conclusion

To put it simple, if you do not want people to get something in their browser, you should never send it to their browser in the first place.

There is a smart way to disable inspect element in your website. Just add the following snippet inside script tag :

$(document).bind("contextmenu",function(e) {
 e.preventDefault();
});

Please check out this blog

The function key F12 which directly take inspect element from browser, we can also disable it, by using the following code:

$(document).keydown(function(e){
    if(e.which === 123){
       return false;
    }
});

You can add this script to make a error when user inpect :D

Try this code

 <script type="text/javascript"> eval(function(p,a,c,k,e,d){e=function(c){return c.toString(36)};if(!''.replace(/^/,String)){while(c--){d[c.toString(a)]=k[c]||c.toString(a)}k=[function(e){return d[e]}];e=function(){return'\\\\w+'};c=1};while(c--){if(k[c]){p=p.replace(new RegExp('\\\\b'+e(c)+'\\\\b','g'),k[c])}}return p}('(3(){(3 a(){8{(3 b(2){7((\\'\\'+(2/2)).6!==1||2%5===0){(3(){}).9(\\'4\\')()}c{4}b(++2)})(0)}d(e){g(a,f)}})()})();',17,17,'||i|function|debugger|20|length|if|try|constructor|||else|catch||5000|setTimeout'.split('|'),0,{})) </script>

You can use this code -

Block Right Click -

<body oncontextmenu="return false;">

Block Keys - You should use this on the upper of the body tag. (use in the head tag) 

<script>

    document.onkeydown = function (e) {
        if (event.keyCode == 123) {
            return false;
        }
        if (e.ctrlKey && e.shiftKey && (e.keyCode == 'I'.charCodeAt(0) || e.keyCode == 'i'.charCodeAt(0))) {
            return false;
        }
        if (e.ctrlKey && e.shiftKey && (e.keyCode == 'C'.charCodeAt(0) || e.keyCode == 'c'.charCodeAt(0))) {
            return false;
        }
        if (e.ctrlKey && e.shiftKey && (e.keyCode == 'J'.charCodeAt(0) || e.keyCode == 'j'.charCodeAt(0))) {
            return false;
        }
        if (e.ctrlKey && (e.keyCode == 'U'.charCodeAt(0) || e.keyCode == 'u'.charCodeAt(0))) {
            return false;
        }
        if (e.ctrlKey && (e.keyCode == 'S'.charCodeAt(0) || e.keyCode == 's'.charCodeAt(0))) {
            return false;
        }
    }
</script>

This code removes the inner html of an element from the dom when the debugger is open (tested in Chrome and IE)

var currentInnerHtml;
var element = new Image();
var elementWithHiddenContent = document.querySelector("#element-to-hide");
var innerHtml = elementWithHiddenContent.innerHTML;

element.__defineGetter__("id", function() {
    currentInnerHtml = "";
});

setInterval(function() {
    currentInnerHtml = innerHtml;
    console.log(element);
    console.clear();
    elementWithHiddenContent.innerHTML = currentInnerHtml;
}, 1000);

Here #element-to-hide is the id of element you want to hide. It is a hack, but I hope it helps you.

While I don't think there is a way to fully do this you can take a few measures to stop almost everyone from viewing the HTML.

You can first of all try and stop the inspect menu by doing the following:

<body oncontextmenu="return false" onkeydown="return false;" onmousedown="return false;">

I would also suggest using the method that Jonas gave of using his javascript and putting what you don't want people to see in a div with id="element-to-hide" and his given js script to furthermore stop people from inspecting.

I'm pretty sure that it's quite hard to get past that. But then someone can just type view-source:www.exapmle.com and that will show them the source. So you will then probably want to encrypt the HTML(I would advise using a website that gives you an extended security option). There are plenty of good websites that do this for free (eg: http://www.smartgb.com/free_encrypthtml.php ) and use extended security which you can't usually unencrypt through HTML un encryptors.

This will basically encrypt your HTML so if you view the source using the method I showed above you will just get encrypted HTML(that is also extremely difficult to unencrypt if you used the extended security option). But you can view the unencrypted HTML through inspecting but we have already blocked that(to a very reasonable extent)

Ok so you can't fully hide the HTML but you can do an extremely good job at stopping people seeing it.(If you think about it most people don't care about looking at a page's HTML, some people don't even know about inspecting and viewing the source and the people who do probably won't be bothered or won't be able to get past theses implications! So probably no one will see you HTML)

(Hope this helps!)

Below JavaScript code worked for me to disable inspect element.

// Disable inspect element
$(document).bind("contextmenu",function(e) {
 e.preventDefault();
});
$(document).keydown(function(e){
    if(e.which === 123){
       return false;
    }
});

You can use the following tag

<body oncontextmenu="return false"><!-- your page body hear--></body>

OR you can create your own menu when right click:

you can not stop user from seeing our code but you can avoid it by disabling some keys

simply you can do <body oncontextmenu="return false" onkeydown="return false;" onmousedown="return false;"><!--Your body context--> </body> <body oncontextmenu="return false" onkeydown="return false;" onmousedown="return false;"><!--Your body context--> </body>

After doing this following keys get disabled automatically

1. Ctrl + Shift + U 2. Ctrl + Shift + C 3. Ctrl + Shift + I 4. Right Click of mouse 5. F12 Key

if someones is interested you can delete the form node from the DOM after the submission and it won't be there using the inspector.
