I have the following html page:
What I am looking to do is capitalize the first letter (which is working without any issue) and strip the textbox of any html code or any code that has a combincation of “<” “/>” “>” so user cannot insert malicious code to execute at server end.
I found a code which strips:
var StrippedString = OriginalString.replace(/(<([^>]+)>)/ig,"");
How do I add the above code to the below page so it takes care of both?
