我有一个 ajax 调用,应该在每次循环后在文件夹中查找新图像,并在下一个循环中显示新图像,但它不能正常工作
这是我的html代码:
<html>
<head>
<meta http-equiv="refresh" content="1000"/>
<title>Slideshow</title>
<style type="text/css">
#slideshow {
position: relative;
}
#slideshow,
#slideshow img {
position: absolute;
top: 0px;
left: 0px;
padding: 15px;
border: 1px solid #ccc;
background-color: #eee;
}
#slide {
width: 370px;
height: 220px;
padding: 0;
margin: 0 auto;
}
#myslides {
width: 370px;
height: 220px;
padding: 0;
margin: 0 auto;
}
#myslides img {
padding: 10px;
border: 1px solid rgb(100,100,100);
background-color: rgb(230,230,230);
width: 350px;
height: 200px;
top: 0;
left: 0
}
</style>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.5/jquery.min.js"></script>
<script type="text/javascript" src="http://cloud.github.com/downloads/malsup/cycle/jquery.cycle.all.latest.js"></script>
<script type="text/javascript">
function loadSlides() {
$.ajax({
type: "GET",
url: "loadajax.php"
}).done(function(response) {
var temp_images = eval("(" + response + ")");
for(ti in temp_images)
{
//alert(temp_images[ti]);
$('#slideshow').append('<img src="images/' + temp_images[ti] + '" alt="">');
}
startSlideshow();
});
}
function startSlideshow()
{
$('#slideshow').cycle({
fx: 'fade',
speed: 700,
timeout: 800
});
}
$(document).ready(function(){
loadSlides();
});
</script>
</head>
<body>
<div id="slideshow" />
</body>
</html>
和我的php代码:
<?php
function returnimages($dirname="./images") {
$pattern="([^\s]+(\.(?i)(jpg|png|gif|bmp))$)";
$files = array();
if($handle = opendir($dirname)) {
while(false !== ($file = readdir($handle))){
if(preg_match($pattern, $file)){ //if this file is a valid image
$files[] = $file;
}
}
closedir($handle);
}
//sort($files);
natcasesort($files);
return($files);
}
$images = returnimages();
echo json_encode($images);
?>
如何解决?
