在文本区域内插入html

Question

I have

<textarea rows="20" cols="100"></textarea>

When i insert html

document.getElementsByTagName('textarea').value = "<p>Content</p>";

The html does not get rendered inside the <textarea />

Is there a way to render html inside textarea?

Answer 1

getElementsByTagName returns a collection of elements (like an array), so you have to specify the index of the one you want. If you only have one use [0]

document.getElementsByTagName('textarea')[0].value = "<p>Content</p>";

Note that you can't render HTML in a textarea though, only text.

Answer 2

You cannot render HTML inside a text area as it is for input. You can only render text
