Clearing Chrome console

Question

I have been trying to get the Chrome console to clear, however it keeps giving me this error:

Uncaught TypeError: Object #<Console> has no method 'clear'

I honestly have no idea why it keeps giving me this error. console.log(...) works and so do many other console functions, just not clear().

<!DOCTYPE HTML>
<html>
    <head>
         <script>
            console.log("Hello, World.");

            console.clear();
        </script>
    </head>

    <body>

    </body>
</html>

Any Ideas?

EDIT: https://developers.google.com/chrome-developer-tools/docs/console#clearing_the_console_history

states "Invoke console.clear() Console API from JavaScript." So I figured there was some way to use the clear() function from within a javascript script, but I guess I misunderstood.

Where did you see Chrome's console had a public function `clear` ? — Denys Séguret, Feb 12 '13 at 08:06
Just do a `for(x in console) console.log(x);` and you'll see that there is no `clear()` method there. — techfoobar, Feb 12 '13 at 08:07
@dystroy - It does has a public function `clear`: http://jsfiddle.net/DerekL/rQwgD/ — Derek 朕會功夫, Feb 12 '13 at 08:09
@Derek See the link I gave. It explains why we don't all have it (for Chrome it depends on the version). There are a few workarounds on this other question too. — Denys Séguret, Feb 12 '13 at 08:10
@dystroy - I didn't know that it wasn't there before. :) I remember there was an old trick to clear console with hacky methods, but probably it won't work now. — Derek 朕會功夫, Feb 12 '13 at 08:12

clear() isn't allow to be called from the page's scripts.

In the console, clear() can be executed. It lives at window.console._commandLineAPI.clear and it works in the console because it's ran in this context...

with ((window && window.console && window.console._commandLineAPI) || {}) {
    // console executed code
}

So there is no way to do it automatically? Darn. – Kyle Messner Feb 12 '13 at 08:12
@KyleMessner Not without assigning a reference to it from the console. – alex Feb 12 '13 at 08:14
@KyleMessner, and that is done by typing this in the console: `window.clear = clear;`. You can then use `clear()`, but you'll have to execute that script in the console manually, each time you load a page. – Cerbrus Feb 12 '13 at 08:17
