         var output=JSON.stringify(res);
         var result=output.substring(3,output.length-3)
         console.log(result);
          if(result.toLowerCase===patientName.toLowerCase){

        inst.emit(':ask', 'patient name does not exist, please try again');
     console.log("not connected due to error: " + err);

我正在尝试使用数据库值验证插槽值，但是在获取第一个插槽的值后，控件始终转到下一个插槽。在要求用户输入第二个插槽之前，如何验证第一个插槽的值？

请帮助
