Hey, I was wondering if anyone knows of any easy ways to detect for HTML input. I have a textarea box that I want users to be able to input either plain text or HTML code. I will later display this input data, so if the user input plain text then I will replace newline characters (\r\n, \n, \r) with <br> tags, but if they input HTML code I don't want to format it before displaying it. Basically is there an easy way to detect HTML code in inputs? If you have any suggestions, please let me know.
