I have an element in my html-code, that holds a completely new html code written by a user, for previewing after codeing into a textarea (simple: a web-editor).
My problem starts when the user types in his code with an id or/and a class, that is already in my code.
So imagine this:
<html> <body> <div id="hi">That is my text</div> <textarea id="here_writes_the_user_his_code"></textarea> <section id="user_input"> <!-- All following is from the user...--> <html> <body> <div id="hi">Too bad, hi has already been used...</div> </body> </html> <!--...til here!--> </section> </body> </html>
Any idea of solving this?
