I can't find any examples when you want the user to input at least x number of characters in a textarea. There is no max length, only minimum. Is there any simple solutions to this?

This is what I have now.

**A simple textarea**

```
<textarea id="textComment" name="comment" ></textarea>

```

**Div area showing x characters remaining to write**

```
<div>Characters left <span id="charsLeft"></span></div>

```

**If possible, disable post button until x characters reached.**

```
<button onclick="frmComment.submit();return false;">Add comment</button>

```
