if you want to get just the response of in chat window, then just use `setInterval('', 1000)` in one minute, and get the data from where you store the chat data. for more info about see the related question http://stackoverflow.com/questions/10613268/not-able-to-handling-ajax-request-from-a-small-chat-module/10613343#10613343 — jogesh_pi, May 24 '12 at 07:14

setTimeout needs to be used in conjunction with clearTimeout. Use clearTimeout whenever a time resetting event occurs.

Example:

<script>
    var interval = -1;
    var TIMEOUT = 5; // seconds
    function doTimeout(){
        alert('show timeout message');
        startClock(); // if you want to restart the timer
    }
    function startClock(event){
        console.log("foo",interval, event);
        if(interval !== -1){
            console.log("clearing timeout");
            clearTimeout(interval);
        }
        interval = setTimeout(doTimeout,TIMEOUT*1000);
    }
    startClock(); // if you want to start the timer on arrival
</script>

<!-- add remove events as you see fit -->
<textarea id="chatinput" onblur="startClock(event)" onfocus="startClock(event)" onchange="startClock(event)" onkeyup="startClock(event)"></textarea>
