问题描述

我正在尝试使用jQuery制作幻灯片，为此我尝试将所有图像的网址存储在一个文件夹中，而不必手动编写它们
看起来我必须玩Ajax ，但我有点困惑
我基本上想在我的PHP代码中将var存储在一个数组中

I'm trying to make a slideshow with jQuery, for this I try to get all of the images' urls stored in a folder without having to write them manualyIt looks like I have to play around with Ajax, but I'm a bit confusedI would basically like to get the var stored in an array in my PHP code

<?php
$dir = "img";
if (is_dir($dir)){
    if ($dh = opendir($dir)){
        $images = array();
        while (($file = readdir($dh)) !== false){
            if (!is_dir($dir.$file)) $images[] = $file;
        }
        closedir($dh);
    }
}
$max = count($images);

那我怎么能快速得到 $ images []的价值？非常感谢帮助！：）

So how could I quickly get the values of $images[] in javascript? Anly help would be very appreciated! :)

`推荐答案`

<?php
$dir = "img";
$images = array();
if (is_dir($dir)){
    if ($dh = opendir($dir)){
        while (($file = readdir($dh)) !== false){
            if (!is_dir($dir.$file)) $images[] = $file;
        }
        closedir($dh);
    }
}

header('Content-Type: application/json');
echo json_encode($images);

只要设置了标题内容类型，jQuery就会自动解析JSON：

jQuery will automatically parse the JSON as long as the header content-type is set:

$.ajax({
 'url' : 'imagelist.php',
 'success': function(result) {
   ...
 },
});
