react-redux实现升序降序排序

*  action.js

下面代码中的patientList是一个数据数组，比较patientList数组中的sirenId，然后patientList这一行数据也排序

export function upSort(patientList) {
      return async dispatch => {
        var sortarr = []
        for (var i = 0; i < patientList.length; i++) {
          for (var j = 0; j < patientList.length - i - 1; j++) {
            if (patientList[j + 1].sirenId > patientList[j].sirenId) {
              var temp;
              temp = patientList[j];
              patientList[j] = patientList[j+1];
              patientList[j+1] = temp;
            }
          }
          sortarr.push(temp)
        }
        console.log('sortarr asc: ',sortarr);
        // dispatch(changeSort(sortarr));
      };
    }
    export function downSort(patientList) {
      return async dispatch => {
        var sortarr2 = []
        for (var i = 0; i < patientList.length; i++) {
          for (var j = 0; j < patientList.length - i - 1; j++) {
            if (patientList[j + 1].sirenId < patientList[j].sirenId) {
              var temp;
              temp = patientList[j];
              patientList[j] = patientList[j+1];
              patientList[j+1] = temp;
            }
          }
          sortarr2.push(temp)
        }
        console.log('sortarr2 desc: ',sortarr2);
        // dispatch(changeSort(sortarr2));
      };
    }
    function changeSort(patientsList) {
      return {
        type: TYPES.PATIENTS_LIST,
        text: patientsList
      };
    }
