[英]Adding items to the end of an array in JavaScript/TypeScript
I have this do while loop 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)
}
THe above works but data is pushed in this form 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 ],
],
What i was looking forward to get is to append the data at the end of the array such that i would get 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 ],
.......
A response from the server that is 来自服务器的响应是
console.log(res.rawdatatrucks);
always starts at 0 even in the other iterations of the while loop. 即使在while循环的其他迭代中,也总是从0开始。
What else do i need to add to the .push method 我还需要添加什么到.push方法中
使用concat
而不是push
。
this.trucks = this.trucks.concat(res.rawdatatrucks);
