JS

function fileUp  () {//文件导入
                let files = $('#inputHover').prop('files');
                if (files.length < 1) {
                    return layer.msg('请选择导入文件！');
                }
                let formData = new FormData();
                formData.append('file', files[0]);
                formData.append('orgCode', this.orgCodeId);//字段key，val，如果没有就删掉
                $.ajax({
                    type: "POST",
                    url: "",
                    data: formData,
                    processData: false,
                    contentType: false,
                    success: function (result) {
                        if (result.success) {
                            layer.msg('上传成功！');
                            // this.initCalendar();
                        } else {
                            layer.msg('上传失败！');
                        }
                    },
                    error: function () {
                        layer.msg('上传失败！');
