Hi all,
I have a textarea element which is populated by an initial user and saved with escaped htmlspecialchars, for example:
I have a button element, which I want to open a pop out browser tab and displays the text area content as rendered HTML. The following code sucessfully opens the new tab and populates it with the content of the textarea:
The popup window sucessfully opens; however, the content is rendered as text like this:
I want it to render as valid HTML code rather than print the HTML.
After much googling, I understand that I need a javascript equivalent of htmlspecialchars_decode. I've found several offerings where people have resolved this issue, but just cannot get any of them to work.
My latest attempt is below:
Please can you help?
Thanks in advance
