    Note:

    I didn't realize how similar this was to Reigel's answer until I read his answer. Basically, the only difference is that I use .delay() to hide the div instead of the interval. Different options...

    If you put the initial number in a <span> this will count down to zero from whatever that number is:

    $(function() {

               // Number of seconds counter starts at is what's in the span
    var timer, counter = $("#hideMsg span").text();

      // Delay the fadeout counter seconds
    $('#hideMsg').delay(counter * 1000).fadeOut('fast');

      // Update countdown number every second... and count down
    timer = setInterval(function() {

        $("#hideMsg span").html(--counter);
        if (counter == 0) { clearInterval(timer)};

    }, 1000);

});​

    jsFiddle example


    This makes use of jQuery's native .delay(), and it uses a setInterval() that stops when it gets to zero.

    Do another set timeout after a second and set the .html() of the div like this:

    setTimeout(function() { $('#hideMsg').html('The entry you posted not valid. <br /> This Box will Close In 1 Second'); }, 1000);

    Put them in a function and run the function onload like this:

    <body onload="function_name()">

    hope this helps.

    use setInterval instead of setTimeout, then with the combination of clearInterval

    var sec = 2
var timer = setInterval(function() { 
   $('#hideMsg span').text(sec--);
   if (sec == -1) {
      $('#hideMsg').fadeOut('fast');
      clearInterval(timer);
   } 
}, 1000);

    html

    <div id="hideMsg">
The entry you posted not valid.
This Box will Close In <span>2</span> Seconds
</div>

    crazy demo

    Making it better.

    var sec = $('#hideMsg span').text() || 0;
var timer = setInterval(function() { 
   $('#hideMsg span').text(--sec);
   if (sec == 0) {
      $('#hideMsg').fadeOut('fast');
      clearInterval(timer);
   } 
}, 1000);​

    so that the time will depends on what is inside the <span>. For example, <span>2</span> is 2 seconds, <span>5</span> is 5 seconds, and <span>60</span> is 1 minute.

    another crazy demo
