Q:

Bootstrap Alert Auto Close

My need is to call alert when I click on Add to Wishlist button and should disappear the alert in 2 secs. This is how I tried, but the alert is disappearing instantly as soon as it is appearing. Not sure, where the bug is.. Can anyone help me out?
JS Script
$(document).ready (function(){
   $("#success-alert").hide();
   $("#myWish").click(function showAlert() {
      $("#success-alert").alert();
      window.setTimeout(function () { 
         $("#success-alert").alert('close'); 
      }, 2000);             
   });      
});

HTML Code:
<div class="product-options">
   <a id="myWish" href="" class="btn btn-mini">Add to Wishlist </a>
   <a href="#" class="btn btn-mini"> Purchase </a>
</div>

Alert Box:
<div class="alert alert-success" id="success-alert">
   <button type="button" class="close" data-dismiss="alert">x</button>
   <strong>Success!</strong>
   Product have added to your wishlist.
</div>

For a smooth slideup:
$("#success-alert").fadeTo(2000, 500).slideUp(500, function(){
    $("#success-alert").slideUp(500);
});

$(document).ready(function() {
  $("#success-alert").hide();
  $("#myWish").click(function showAlert() {
    $("#success-alert").fadeTo(2000, 500).slideUp(500, function() {
      $("#success-alert").slideUp(500);
    });
  });
});

Using a fadeTo() that is fading to an opacity of 500 in 2 seconds in "I Can Has Kittenz"'s code isn't readable to me. I think it's better using other options like a delay()
$(".alert").delay(4000).slideUp(200, function() {
    $(this).alert('close');
});

Why all the other answers use slideUp is just beyond me. As I'm using the fade and in classes to have the alert fade away when closed (or after timeout), I don't want it to "slide up" and conflict with that.
Besides the slideUp method didn't even work. The alert itself didn't show at all. Here's what worked perfectly for me:
$(document).ready(function() {
    // show the alert
    setTimeout(function() {
        $(".alert").alert('close');
    }, 2000);
});
