当关闭UploadCare对话框时,我希望显示警报,但事实并非如此。为什么不呢?''

$('#uc_open').on('click', function() {
    uploadcare.openDialog(null, {
        imagesOnly: true
        }).done(function(file) {
            file.done(function(fileInfo) {
                //
            }).fail(function(error, fileInfo) {
                alert(error);
            });
        });
    return false;
});

您已订阅openDialog().done()。当用户选择文件并在对话框中单击“完成”时,将调用此回调。在此回调中,您会收到file个对象并订阅file.fail()回调。当文件上传因网络错误或验证器不满意而失败时,将调用此回调。

如果您想在用户关闭对话框时订阅回调而不选择文件(通过单击右上角的×或按ESC键),您应该订阅openDialog().fail()

$('#uc_open').on('click', function() {
    // Open the dialog on button cick
    uploadcare.openDialog(null, {
        imagesOnly: true
        }).done(function(file) {
            // User has just clicked "Done" in Uploadcare dialog
            file.done(function(fileInfo) {
                // File uploading succeeded
            });
        }).fail(function(error, fileInfo) {
            // User just has closed the dialog by pressing ESC or clicking on "×"
            alert(error);
        });
    return false;
});
