javascript - Using setTimeout to delay timing of jQuery actions

I am attempting to delay the swapping of text in a div. It should operate like a slider/carousel for text.

I must have the code wrong, as the final text replacement never happens.

Also, how would I animate introducing the replacement text (window blinds, for eg.)?


<html>
    <head>
        <script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
        <script src="//ajax.googleapis.com/ajax/libs/jqueryui/1.10.3/jquery-ui.min.js"></script>
        <link rel="stylesheet" href="http://code.jquery.com/ui/1.9.1/themes/base/jquery-ui.css" />

        <script type="text/javascript">
$(document).ready(function() {

    $("#showDiv").click(function() {
        $('#theDiv').show(1000, function() {
            setTimeout(function() {
                $('#theDiv').html('Here is some replacement text', function() {
                    setTimeout(function() {
                        $('#theDiv').html('More replacement text goes here');
                    }, 2500);
                });
            }, 2500);
        });
    }); //click function ends

}); //END $(document).ready()

        </script>
    </head>
<body>

    Below me is a DIV called "theDiv".<br><br>
    <div id="theDiv" style="background-color:yellow;display:none;width:30%;margin:0 auto;">
        This text is inside the Div called "theDiv".
    </div><br>
    <br>
    <input type="button" id="showDiv" value="Show DIV">



</body>
</html>

.html() only takes a string OR a function as an argument, not both. Try this:

 $("#showDiv").click(function () {
     $('#theDiv').show(1000, function () {
         setTimeout(function () {
             $('#theDiv').html(function () {
                 setTimeout(function () {
                     $('#theDiv').html('Here is some replacement text');
                 }, 0);
                 setTimeout(function () {
                     $('#theDiv').html('More replacement text goes here');
                 }, 2500);
             });
         }, 2500);
     });
 }); //click function ends
