Textarea onchange detection
javascript
Solution
You will need to use `onkeyup` and `onchange` for this. The onchange will prevent context-menu pasting, and the onkeyup will fire for every keystroke.
See my answer on How to impose maxlength on textArea for a code sample.
Problem
How do I detect change event on textarea using javascript? I'm trying to detect how many characters left is available as you type. I tried using the onchange event, but that seems to only kick in when focus is out.
