avue下拉多选

{
      label: "破损类型",
      prop: "damageType",
      type: "select",
      dicUrl: "/api/blade-system/dict-biz/dictionary?code=damageType",
      props: {
        label: "dictValue",
        value: "dictKey"
      },
      width: 120,
      multiple: true,
    },

    rowSave(row, done, loading) {
        // 将 row中字段 damageType  数组转字符串 逗号分隔
        row.damageType = JSON.stringify(row.damageType).replace(/\"/g, "");
        console.log(row);

rowUpdate(row, index, done, loading) {
        // 将 row中字段 damageType  转成json
        row.damageType = JSON.stringify(row.damageType).replace(/\"/g, "");

或者直接在下面加   就不需要方法里解析了

{
      label: "破损类型",
      prop: "damageType",
      type: "select",
      dicUrl: "/api/blade-system/dict-biz/dictionary?code=damageType",
      props: {
        label: "dictValue",
        value: "dictKey"
      },
      width: 120,
      multiple: true,
      valueFormat: (val) => { 
        if (val) {
          return val && val.length > 0 ? val.join(',') : '';
        }
      }
    },
