6个参数控件(org_list_1,org_list_3,var_d_date,var_status,var_start_time,var_end_time)，

各自绑定了数据源，导出按钮(out_put)自定义js如下:

var var_org_list_1 = this.options.form.getWidgetByName("org_list_1").getValue();
var_org_list_1 = "\"" + var_org_list_1 + "\"";

var var_org_list_3 = this.options.form.getWidgetByName("org_list_3").getValue();
var_org_list_3 = "\"" + var_org_list_3 + "\"";

var var_d_date = this.options.form.getWidgetByName("d_date").getValue();
var_d_date = "\"" + var_d_date + "\"";

var var_status = this.options.form.getWidgetByName("status").getValue();
var_status = "\"" + var_status + "\"";

var var_start_time = this.options.form.getWidgetByName("start_time").getValue();
var_start_time = "\"" + var_start_time + "\"";

var var_end_time = this.options.form.getWidgetByName("end_time").getValue();
var_end_time = "\"" + var_end_time + "\"";

var paramStr = encodeURIComponent(
 "{org_list_1:" + var_org_list_1 + ",org_list_3:" + var_org_list_3 + ",d_date:" + var_d_date + ",status:" + var_status + ",start_time:" + var_start_time + ",end_time:" + var_end_time + "}")

var colNames = encodeURIComponent("")

_g().directExportToExcel("output", "数据汇总表", paramStr, colNames);

导出后提示保存EXCEL文件，但是打开文件报错，
