Can anyone suggest a method to block the execution of Javascript commands in the console?

Regarding the inquiry mentioned in the question title.

Is it possible to prevent individuals from executing functions on my webpage using the console, even though it is not necessary?

I have experimented with various methods, and the code below represents the closest I have come to a solution - unfortunately, it does not work as intended :(

    window.onresize = function(){
        if((window.outerHeight - window.innerHeight) > 100) {
            //stop commands here?
        }
    }
    window.onload = function() {
        if (typeof console !== "undefined" || typeof console.log !== "undefined") {
            if (window.console && (window.console.firebug || window.console.exception)) {
                    //stop commands here?
            }
        }
    }

EDIT:
I do not necessarily need to disable the console entirely; I just want to prevent function calls being made within it - either solution would suffice ;)

EDIT2:
So, as it stands, there seems to be no foolproof way of detecting the console across different browsers. Is this correct?

EDIT3:
As a temporary workaround, I have implemented the following approach. Although the JavaScript functions remain intact, the associated elements have been removed... It's not an ideal fix, but it will serve its purpose for now... :(

        setInterval(function() {
            if (!$.browser.mozilla) {
                if((window.outerHeight - window.innerHeight) > 100) {
                    alert("DISABLED!");
                    $('body').remove();
                    return false;
                }
            }
            if (window.console && (window.console.firebug || window.console.exception)) {
                alert("DISABLED!");
                $('body').remove();
                return false;
            }
        }, 750);

Answer №1

Avoid attempting to detect the console based on window width as it may lead to compatibility issues with other browsers. If your goal is to protect your functions:

For example, if you have a button:

<button onclick="someFunction()"></button>

The someFunction can be accessed through the console. However, if you conceal the function name from the user, they will not be able to call it.

<script type="text/javascript">
//obfuscate this code
$(function() {
$("#theButton").on("click", someFunction);
})
</script>
<button id="theButton"></button>

This is just one potential solution. It's important to remember that no JavaScript solution can guarantee 100% security since users have access to all of your code, obfuscated or not.
