循环调用一个接口 等待最后一次返回值Promise

async submits() {
      let trues = [];
      if (this.tableData.length > 0) {
        this.submitshow = true;
        this.tableData.forEach(async (item) => {
          if (item.status != '2') {
            trues.push(
              new Promise(async (resolve, reject) => {
                let data = {
                  picklistsId: item.id,
                };
                let result = await PickPicklists(data);
                resolve(result);
              })
            );
          }
        });
        Promise.all(trues).then((res) => {
          this.submitshow = false;
          this.cancel();
        });
      }
    },
