Where to place the timeout() fadeout?

Question

Hello.

function checkSession(){
    $.ajax({url: "session.php", success: function(data){
         if( data == 1){
            var postFilen = 'msg.php';
            $.post(postFilen, function(data){
            $(".msg").html(data).find(".message2").fadeIn("slow")
         }else{ 
             $('.msg').hide();
         }
    }});
// setInterval('checkSession()',1000);

Now i want to place to fadeout .msg after 5 seconds it has been shown. How do i do this.. i have tried:

function checkSession(){
    $.ajax({url: "session.php", success: function(data){
         if( data == 1){
            var postFilen = 'msg.php';
            $.post(postFilen, function(data){
            $(".msg").html(data).find(".message2").fadeIn("slow")
                    setTimeout(function() {
    $('.msg').fadeOut('slow');
        }, 5000);
            });  
         }else{ 
             $('.msg').hide();
         }
    }});
// setInterval('checkSession()',1000);
}

But then the message wont appear after 1st time..

Try to work with the delay method: http://api.jquery.com/delay/

 $('#foo').slideUp(300).delay(800).fadeIn(400);

I your case, something like:

 $(".msg")
   .html(data)
   .find(".message2")
   .fadeIn("slow")
   .parent('.msg')
   .delay(5000)
   .fadeOut('slow')

This one seems to work fine here:

<div class="msg"></div>
<p>
    Some text <br /> <a id="bloup" href="">show message</a>
</p>

and then

   $(function() {
      $("#bloup").click(function(e) {
          e.preventDefault();

          var data = "<span class='message2'>Hello world</span>";

          $(".msg")
              .show()
              .html(data)
              .find('.message2')
              .fadeIn('slow')
              .parent('.msg')
              .delay(2000).fadeOut('slow');
      }) 
   });

First try to write cleaner code for us to understand your problem better, your $.post's callback function missing }); these chars at its end on first snippet on top, and indentation is bad on second.

Then check out these links to understand the use of setTimeout.

And to your question :

if you put var t = before setTimeout(function() { it would work as expected,

Hope these helps, Sinan.
