我正在使用这个包，并对其进行了一些修改，以便我可以上传、拖动和排序图像并在浏览器中预览它们。上传工作正常，并删除图像。但是我发现了脚本中断的情况。当我有多个图像并且我删除了第一个图像时，尝试上传我删除的相同图像时，脚本不再起作用。但是，如果我不尝试立即上传相同的图像，而是先上传其他图像，然后再上传已删除的图像，那么它就可以了。另外，我在控制台中没有任何错误。我不知道如何解决这个问题。
我的完整代码在这里。
这是代码的一部分：
$(document).ready(function () {
var imageCounter = 0;
$('#articleForm').submit(function () {
uploadPosition();
});
function uploadPosition() {
var uploadedImagesPositions = [];
$.each($('.jFiler-item-thumb-image'), function (index, value) {
$(this).attr('data-position-index', index);
uploadedImagesPositions[index] = $(this).find('img').attr('src');
});
if (!$('input[name="uploadedItems"]').length) {
$('<input>', {
type: "hidden",
name: "uploadedItems"
}).appendTo('#articleForm')
}
$('input[name="uploadedItems"]').val(JSON.stringify(uploadedImagesPositions));
$("input[name^='jfiler-items-exclude-']:hidden").detach();
console.log(uploadedImagesPositions);

更新
我已经用 HTML 和 CSS 以及 javascript 代码更新了fiddle ，不幸的是，我无法让它工作，所以不确定它有多大帮助，但至少你可以看到完整的代码。我在上传图片的页面上使用此脚本：
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/2.2.3/jquery.min.js" integrity="sha384-I6F5OKECLVtK/BL+8iSLDEHowSAfUo76ZL9+kGAgTRdiByINKJaqTPH/QVNS1VDb" crossorigin="anonymous"></script>
<script type="text/javascript" src="{{ asset('js/foundation/foundation.min.js') }}"></script>
<script>$(document).foundation();</script>
<script type="text/javascript" src="{{ asset('js/jquery-ui/jquery-ui.min.js') }}"></script>
<script type="text/javascript" src="{{ asset('js/jquery-filer/jquery-filer.js') }}"></script>
jquery-filer是我用于上传的脚本，我正在使用的那个。
这是我用于 ajax 上传的服务器端功能。我在后端使用 PHP laravel：
public function ajaxUpload() {
if (Input::hasFile('file')) {
$files = Input::file('file');
foreach ($files as $file) {
$time = microtime(true);
$name = $file->getClientOriginalName();
$filename = $time.'-'.preg_replace('/[(\)\s]/u', '', $name);
if(substr($file->getMimeType(), 0, 5) == 'image') {
try {
$original = Image::make($file)->save(public_path($this->destinationPath.'/'.$filename));
\Log::info('try: '.$filename."\n");
} catch (Exception $e) {
\Log::info('Caught exception: '.$e->getMessage(). "\n");
}
$img = Image::cache(function($image) use ($original){
return $image->make($original);
});
}
}
}
return $this->destinationPath.$filename;
}
