ajax模拟表单提交，后台使用npoi实现导入操作 方式二

页面代码：

 <form id="form1" enctype="multipart/form-data">
                <div style="float:right">
                    &nbsp;
                    <button type="button" class="btn btn-primary" onclick="$('#fileUpload').click()" id="reviewFile">浏览</button>
                    <button class="btn btn-primary" type="button" style="margin-left:5px;height:30px;" id="dataExport">批量导入</button>
                    <input type="button" class="btn btn-primary" style="margin-left:5px;height:30px;" id="downLoad" value="下载模板">
                </div>
                <div style="float:right;margin-top:5px">
                    <input id="fileUpload" name="fileUpload" type="file" style="display:none" />
                    <input id="fileText" type="text" class="form-control" disabled />
                </div>
                <script>
                    $("#fileUpload").change(function () {
                        $("#fileText").val($(this).val());
                    })
                </script>
            </form>

js代码：

 //导入excel数据
        $("#dataExport").click(function () {
            var formData = new FormData($('form')[0]);
            $.ajax({
                url: '/BaseInfoPage/GetAllDataFromExcel',
                type: 'POST',
                xhr: function () {
                    return $.ajaxSettings.xhr();
                },
                data: formData,

                            location.reload();    //刷新父页面   第二个参数设置msg显示的时间长短
                        });
                    } else {
