you could try: document.getElementsByTagName('script')[0].innerHTML = '';

According to your code block you posted, it seems that you would like to strip script tags from the value of a form element (e.g. a textarea). Sanitizing user input on client side is generally considered to be a bad idea, because this kind of security measure can be easily bypassed. A better solution would be stripping the script tags from the posted data on the server side.

Here is an example in php:

$data = $_POST['fieldname'];

$outputData = strip_tags($data, array(/* here you can specify the allowed html tags, all others will be stripped */);

echo $output;
