FineUploader - "isBrowserPreviewCapable“变量不被Chrome 40抛出，尽管它应该

Question

我注意到，在FineUploader服务器演示(s3dem-微图-cors.php)中，有一个区域可以检查浏览器是否支持预览。它只检查这个post变量：$_POST"isBrowserPreviewCapable“

在这里我想问的是，我实际上是在使用Chrome 40，而且我绝对相信我的浏览器可以使用这个预览。但是在FineUploader发出的“FineUploader”ajax调用中，它不包含$_POST"isBrowserPreviewCapable“。

这里是我的上传成功AJAX调用的示例转储。我想知道我是否错过了一些这样的配置：

精细的Uploader不会发送你所说的POST变量。S3在http://fineuploader.com/demos上的演示包括一行确保随请求发送参数的代码。

例如，配置了以下选项：

uploadSuccess: {
        endpoint: "http://s3-demo.fineuploader.com/s3demo-thumbnails-cors.php?success",
        params: {
            isBrowserPreviewCapable: qq.supportedFeatures.imagePreviews
        }
}
