我是一个初学者。请帮助我通过下拉选择所选的值和名称或标签。我'导入'选择React
React代码

const [task,settask] = useState([]);
const handleEmpChange=(e) => {
    if(e.label){
      let a =e.label
      setAssigntaskD({...assigntaskD,['Employee'] : e.label });
      setAssigntaskD({...assigntaskD, ['EmployeeId'] : e.value });
      debugger;
    }
    else{
      setAssigntaskD({...assigntaskD,[e.target.value] : e.target.value });
      setAssigntaskD({...assigntaskD,[e.target.name] : e.target.name });
  }
}
#HTML#

<Form.Group as={Row} className="mb-3" id="LbUser">
        <Form.Label column sm="2">Employee</Form.Label>
          <Col sm="10" style={{width:'50%'}}>
            <Select value={selectedOptions} options={employeeD} onChange ={(selectedOptions)=>handleEmpChange(selectedOptions)} />
            <p align='left'>
                {errors.UserName && <span class="text-danger" style={{width:'50%'}}>{errors.UserName}</span>}
            </p>
          </Col>
 </Form.Group>
