在JavaScript / TypeScript中将项目添加到数组的末尾

Question

我有这个做while循环

trucks = [];
fetchdata(){
    this.trucks = [];

    do {

     this._reportService.getReports({
        ..//pagination stuff here
        })
        .subscribe(res=> {
          this.trucks.push(res.rawdatatrucks);
        })
    } while(i<this.totalRecords);
    console.log(this.trucks)

}

以上工作正常，但数据以这种形式推送

0:[
    0:[ ...truck data stuff ],
    1:[ ...truck data stuff ],
    2:[ ...truck data stuff ],
    3:[ ...truck data stuff ],
 ],
 1:[
    0:[ ...truck data stuff ],
    1:[ ...truck data stuff ],
    2:[ ...truck data stuff ],
    3:[ ...truck data stuff ],
 ],

我期待得到的是将数据附加到数组的末尾，这样我就可以得到

console.log(this.trucks)

     0:[ ...truck data stuff ],
    1:[ ...truck data stuff ],
    2:[ ...truck data stuff ],
    3:[ ...truck data stuff ],
    4:[ ...truck data stuff ],
    5:[ ...truck data stuff ],
    6:[ ...truck data stuff ],
    .......

来自服务器的响应是

console.log(res.rawdatatrucks);

即使在while循环的其他迭代中，也总是从0开始。

我还需要添加什么到.push方法中

Answer 1

使用concat而不是push 。

this.trucks = this.trucks.concat(res.rawdatatrucks);
