checkspell textbox words onkeyup event
<p>I have a textbox. What I want is when user enters a word in that textbox, it should call <code>onkeyup</code> function and in the function we should check if spelling is correct or not. </p>

<p>If it is correct we don't do anything if its not we should display an alert message and remove all text from the textbox. Please tell what is the best way to do this? </p>
