Nivo Slider dose not load the Ajax response from PHP file - php

Question

I'm trying import images to HTML using PHP, but NivoSlider not loaded that.
I looked for the cause of the problem.
I am printing a alert message of response and the right.
Here is the HTML and AJAX query:
<div id="workcontent" class="pcontent" style="display:none;">
<div class="slider-wrapper theme-default">
<div id="slider" class="nivoSlider">
</div>
</div>
<script>
$(document).ready(function() {
var wl = $('#worklist div');
wl.on('click', function(){
var name = $(this).attr('id');
console.log(name);
$.ajax({
url: 'read.php',
type: 'POST',
data: { data : name }
}).done(function (response) {
$('#slider').prepend(response);
alert(response);
});
});
});
</script>
<div id="back"></div>
<div id="backcontainer">
<div id="back">
Back
</div>
</div><!--End backcontainer-->
</div><!--End content-->
And here is the other jQuery:
<script>
$(document).ready(function() {
$('#slider').nivoSlider(function(){alert('OK');});
});
</script>
This alert don't show! ):
Finally, here is the PHP code:
<?php
if (isset($_POST["data"])){
if ($_POST["data"] == "") {
echo "data ures";
} else {
$data = $_POST["data"];
$fname = "content/".$data."/*.*";
$files = glob($fname);
for ($i=0; $i<count($files); $i++)
{
$num = $files[$i];
echo '<img src="'.$num.'" data-thumb="'.$num.'">';
}
}
} else {
echo "nem jott data";
}
?>
Sorry for my bad english

NivoSlider doesn't take a function as an argument.
Also .nivoSlider() is probably called before the AJAX call returns it's response.
A better solution would be:
$(document).ready(function() {
$.ajax({
url: 'read.php',
type: 'POST',
data: { data : name }
}).done(function (response) {
$('#slider').prepend(response).nivoSlider( {} );
});
});
Now you can be fairly sure #slider contains the images from the response body so NivoSlider can act on them.
