javascript - Rendering HTML inside textarea

Question

I need to be able to render some HTML tags inside a textarea (namely <strong>, <i>, <u>, <a>) but textareas only interpret their content as text. Is there an easy way of doing it without relying on external libraries/plugins (I'm using jQuery)? If not, do you know of any jQuery plugin I could use to do this?

Answer 1

This is not possible to do with a textarea. What you are looking for is an content editable div, which is very easily done:

<div contenteditable="true"></div>

jsFiddle

div.editable {
    width: 300px;
    height: 200px;
    border: 1px solid #ccc;
    padding: 5px;
}

strong {
  font-weight: bold;
}

<div contenteditable="true">This is the first line.<br>
See, how the text fits here, also if<br>there is a <strong>linebreak</strong> at the end?
<br>It works nicely.
<br>
<br><span style="color: lightgreen">Great</span>.
</div>
