SetTimeout does not wait for the specified number of milliseconds

I would like to have a function that runs the submit function after a few seconds of inactivity (using an event onKeyup).

My code is as follows:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
        <title>Title</title>
    </head>
    <body>
        <form id="getJSONForm">
            <textarea rows="1" cols="10" onKeyUp="onKeyUp()"></textarea>
            <input type="submit" value="Submit" id="getJSON" />
        </form>

        <div id="result"  class="functions"></div>

        <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
        <script type="text/javascript">
            $.ajaxSetup ({
                cache: false
            });

            var timer;

            function onKeyUp() {
                stoper();
                timer = setTimeout ( $("#getJSONForm").submit(), 10000 ); 
            }

            function stoper() {
                clearTimeout(timer);
            }

            $("#getJSONForm").submit(function(){
                    $("#result").html("hello");
                    return false;
            });
        </script>
    </body>
</html>

But ... forms are obtained in every event onKeyup. It does not wait until the timer reaches the specified 10,000 milliseconds. Is there any way to fix this?

The first parameter setTimeout()should be a function object (or a string, but you should not use this). Like this:

timer = setTimeout(function () {
   $("#getJSONForm").submit();
}, 10000);

You are currently passing the value $("#getJSONForm").submit()to setTimeout(), which is probably not what you want.

, jQuery HTML. , . :

$('#getJSONForm textarea').keyup(function () {
   // the content of your onKeyUp() function goes here
});
