textarea

Hello,

I have a HTML Tag <textarea>$FOO</textarea> and the $FOO Variable will be filled with arbitrary HTML and JavaScript Content, to be displayed and edited within the textarea. What kind of "escaping" do I neet to apply to $FOO?

I first tought of escaping it HTML but this didnt work (as I will then get shown not the original HTML Code of $FOO but rather the escaped content. This is of course not what I want: I want to be displayed the unescaped HTML/JS Content of the variable...

Is it impossible to display HTML Content within a <textarea> tag and also allow it to be editable as full HTML?

thanks jens
