How to save JS code through WYSIWYG editor?

Question

PHP

Hello!
Help with advice or deed) How can I save JavaScript code through a WYSIWYG editor?
Those. we have the nicEdit editor. In theory, you need to enter it there - this script is saved not as just text, but as a script. And when editing, you need it to be displayed as text) The $_POST['content'] array is transmitted to the server and saved using PHP in MYSQL I hope I explained it clearly) <script>alert(123);</script>

Answer 1

A piece of text becomes an executable script when it is inside < script > tags, and in your editor it is between < div > tags.
I hope I answered clearly)
