Question

我有一个手动激活的上传器的实例：

var manualuploader = new qq.FineUploader({
    element: $('#jquery-wrapped-fine-uploader')[0],
    request: {
        endpoint: '/data/assets/ajax/uploader.php'
    },
    autoUpload: false,
    text: {
        uploadButton: '<i class="icon-plus icon-white"></i> Select Files to upload'
    },
    chunking: {
        enabled: true,
        partSize: 50000000
    },
    resume: {
        enabled: true
    },
    debug: true,
    callbacks: {
        onComplete: function (id, fileName, response) {
            $('#uploader').append('<input type="hidden" name="fileasdf[]" value="' + response.originalName + '" />');
            submitForm.call(this);
        },
        onError: function (event, id, name, errorReason, xhrOrXdr) {
            alert(qq.format("Error on file number {} - {}.  Reason: {}", id, name, errorReason));
        }
    }
    });
    $('#triggerUpload').click(function() {      
    manualuploader.uploadStoredFiles();
});

我指定了一个chunk文件夹，我可以看到上传的块。文件上载过程正常完成。

但是，如果取消或意外终止，则不会恢复上传。块仍然存在于目录中，所有标准浏览器cookie都已启用，但简历不会发生。

分块调试输出如下。我上传了几个块，取消并重新尝试上传：

知道为什么会这样吗？

我还有另一个与问题无关的查询。对于onComplete回调，我只想触发submitForm.call（this）函数（提交表单）。但是，如果我只指定onComplete: submitForm.call(this)，则会抛出错误，表示未定义onComplete响应...

为赛格威道歉，再次感谢。

取消的文件不符合恢复条件。此外，从5.0开始，cookie不再用于保留简历数据：我们使用localStorage代替。您的日志消息表明该文件已被取消，这意味着它无法恢复。

onComplete回调需要一个函数作为值。相反，您正在调用一个函数并将该函数的返回值设置为onComplete的值。这听起来像是对Function.prototype.call在JavaScript中的作用的误解。 call执行一个函数。如果要使用备用上下文构造新函数，请改用Function.prototype.bind。请注意，IE8及更早版本不支持bind。如果您需要支持IE8或更早版本，可以使用Fine Uploader's bind alternative: qq.bind。

FineUploader Chunked上传不恢复
