javascript - Fine Uploader 上传成功后重试

Question

我正在使用很好的 uploader ，它运行得很好。现在，即使上传成功，它也会重试。这样一来，我就有了四个文件，而不是只有一个。

http://fineuploader.com/

我的代码:

<!-- The element where Fine Uploader will exist. -->
<div id="qq-drop-zone">
    <div id="fine-uploader"></div>
    <span class="dragndrop">Drag and Drop</span>
</div>

<!-- Fine Uploader -->
<script src="/modules/fine-uploader/fine-uploader.min.js" type="text/javascript"></script>

<script type="text/template" id="qq-template">
    <div class="qq-uploader-selector qq-uploader" qq-drop-area-text="Drop files here">

XHR 响应文本中存在额外文本，导致 JSON 无效。如果没有有效的响应，它会注册为上传失败并开始重试。我删除了多余的文本，它又可以工作了。
