upload.render({
    elem: '#sc_file',
    url: '{:url("uploadSc")}',
    exts:'doc|docx|pptx|ppt|zip|rar',
    //操作成功的回调
    done: function (res, index, upload) {
        //如果上传失败
        if(res.code == 1){
            $('#filepath').val(res.msg)
        }else{
            layer.alert(res.msg);
        }
    },
    //上传错误回调
    error: function (index, upload) {
        layer.alert('上传失败！' + index);
    }
});
