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>

Answer

.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
