我正在使用以下代码从文件夹中动态选择图像，然后在幻灯片中显示它们。但是此代码仅选择第一张图像...请指导我错误在哪里...
PHP文件是：命名：test.php
<?php
header("content-type: application/x-javascript");
function returnimages($dirname=".") {
$files = array();
$curimage = 0;
//valid image extensions
$pattern="(\.jpg$)|(\.png$)|(\.jpeg$)|(\.gif$)";
if($handle = opendir($dirname)) {
while(false !== ($file = readdir($handle))) {
if(eregi($pattern, $file)){
echo 'galleryarray[' . $curimage . '] = "' . $file . '";';
$curimage++;
}
}
closedir($handle);
}
return($files);
}
//Define array in JavaScript returnimages()
//Output the array elements containing the image file names
echo 'var galleryarray = new Array();';
?>
html代码是：
<html>
<head>
<title></title>
<script src="test.php"></script>
<script type="text/javascript">
var galleryarray = returnimages();
var curimg = 0;
function rotateimages(){
// var imagesDirectory = "pics/" + galleryarray[curimg];
var imagesDirectory =galleryarray[curimg];
document.getElementById("slideshow").setAttribute("src", imagesDirectory)
curimg = (curimg < galleryarray.length - 1) ? curimg + 1 : 0
}
window.onload = function(){
setInterval("rotateimages()", 2500)
}
</script>
</head>
<body>
<img width="468" height="312" id="slideshow" src="Slide1.jpg">
</body>
</html>
