The question you should be asking is:

How can I render text containing HTML as text instead of HTML?

As your examples are all about HTML, not script.

Since you are using jQuery, add it to the document using $element.text(text) and not $element.html(text).

You need to Encode the text written by the users.

Most common way is doing it server side, for example using ASP you'll need to:

strData = Server.HTMLEncode(strData);

And then if the data contains <b>hello</b> the users will see it literally.

To do it client side: HTML-encoding lost when attribute read from input field
