angular6实现对象转换数组对象

1 使用表单获取到数据以后，是对象类型的数据如下图

而后台需要返回的数据是这种key：value的形式传入

2 废话不多说直接上代码（代码只截取部分，仅供参考跑不起来，最后又一个小demo可以运行）

 public discountArr = []; // 折扣数组容器

  public discountContent = { 'name': '', 'value': '' }; // 折扣转换对象容器

  public setDiscount = {}; // 折扣返回数据

 ngOnInit() {

    // 页面初始化发送请求获取数据折后

    this.service.getProductDiscount(this.userId).subscribe(data => {

      if (data.code !== 0) {

        // TODO 错误处理

        console.log(data.message);

      } else {

       返回成功后把获取到的数据赋值给页面的数据

        console.log(data, '折扣');

        this._discount.EIP = data.result.EIP;

        this._discount.EBS = data.result.EBS;

        this._discount.ECS = data.result.ECS;

        this._discount.SLB = data.result.SLB;

        this._discount.OSS = data.result.OSS;

        this._discount.CPS = data.result.CPS;

        this._discount.CAAS = data.result.CAAS;

        this._discount.VPC = data.result.VPC;

        this._discount.SBW = data.result.SBW;

        this._discount.RDSMysql = data.result.RDSMysql;

        this._discount.CDN = data.result.CDN;

      }

    });

  // 表单获取到的数据

    this.discount = this.fb.group({

      EIP: [10, [Validators.required]],

      EBS: [9, [Validators.required]],

      ECS: [null, [Validators.required]],

      SLB: [null, [Validators.required]],

      OSS: [null, [Validators.required]],

      CPS: [null, [Validators.required]],

      CAAS: [null, [Validators.required]],

      VPC: [null, [Validators.required]],

      SBW: [null, [Validators.required]],

      RDSMysql: [null, [Validators.required]],

      CDN: [null, [Validators.required]],

    });

    console.log(this.discount.value);

  }

  //  表单提交执行函数

  onSubmit() {

    // tslint:disable-next-line:forin

   //  循环表单获取的数据

    for (const key in this.discount.value) {

     // 每次执行行前让新对象为空

      this.discountContent = { 'name': '', 'value': '' };

      //  如果为空的话

      if (!this.discountContent[key]) {

       // 把拆分开的数据分别放入key value

        this.discountContent.name = key;

        this.discountContent.value = this.discount.value[key];

      }

      //  每次拆分成功插入数组

      this.discountArr.push(this.discountContent);

    }

    // 转换成后台需要的数据格式

    this.setDiscount = {

      operatorId: this.marketId,

      discount: this.discountArr,

    };

     console.log(this.setDiscount);

    // 发送修改记录

    this.service.changeProductDiscount(this.userId, this.setDiscount).subscribe(data => {

      if (data.code != 0) {

        // TODO 错误处理

        this.notification.create(`error`, '失败',

          data.message);

      } else {

        this.notification.create(`success`, '成功',

          '折扣已修改成功');

      }

    });

  }
