TS组件
import { Component } from '@angular/core';
import { NgForm } from '@angular/forms';
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent {
arr: any[]=[];
onSubmit(form : NgForm) {
this.arr = form.value
console.log('array', this.arr);
console.log('value', form.value);

To see the values of the objects you can json prettifier it like so:
要查看对象的值，您可以像这样使用 json 修饰符：
onSubmit(form:NgForm ) {
this.arr = form.value;
console.log(JSON.stringify( this.arr));
console.log(JSON.stringify( form.value));
}
This will take a JSON object string and return it pretty-printed/formatted
这将采用 JSON 对象字符串并以漂亮的打印/格式返回它
