I want to display an alert() box, just 10 seconds after user stops writting in a textbox.

I used following javascript code to open alertbox -

function txtkeyup(e){
  setTimeout(function () {
    alert('submit?');
  }, 10000);
  return true;
}

and the HTML code is -

<input type='textbox' name='searchquery' value='' onkeyup='return txtkeyup();'>

Now the browser is giving alertbox, 10 seconds after every onkeyup event in the inputbox. To make only one request, i have to reset the setTimeout() timer on every keyup event so the alertbox will be display if user doesnt press a button for 10 seconds.

How can reset the timer of previously called 'setTimeout()' in javascript? Please guide me..

var myTimeout = setTimeout ( ...)

to clear it simply write clearTimeout(myTimeout);
