Question

我是棱角分明的新人，目前正致力于我的个人项目。我有一个关于如何将新数据插入表行的问题。任何人都可以给我片段/示例如何做到这一点？

以下是表单和表格标题：

<!--app.component.html-->

<!--show modal-->
<a href="#" (click)="smModal.show()" popover="Tambah Data Mhs" placement="bottom" triggers="mouseenter:mouseleave">ADD</a>

<!--Modal-->
<div class="container">
    <div bsModal #smModal="bs-modal" class="modal fade" tabindex="-1" role="dialog" aria-labelledby="mySmallModalLabel" aria-hidden="true" id="myModal">
        <div class="modal-dialog modal-sm">
          <div class="modal-content">
            <div class="modal-header">
              <h4 class="modal-title pull-left">Add</h4>
              <button type="button" class="close pull-right" aria-label="Close" (click)="smModal.hide()">
                <span aria-hidden="true">&times;</span>
              </button>
            </div>
            <div class="modal-body">
              <form>
                <label>ID</label>
                <input type="text" class="form-control" placeholder="id">

                <label>name</label>
                <input type="text" class="form-control" placeholder="name">

                <label>year</label>
                <input type="text" class="form-control" placeholder="year">

                <label>major</label>
                <input type="text" class="form-control" placeholder="major">

                <label>address</label>
                <input type="text" class="form-control" placeholder="address">

                <label>Email</label>
                <input type="text" class="form-control" placeholder="email">

                <label>phone</label>
                <input type="text" class="form-control" placeholder="phone"><br>
                
                <button type="submit" class="btn btn-primary">Simpan</button>
                <button class="btn btn-danger">Batal</button>
              </form>
            </div>
          </div>
        </div>
      </div>
<!--enf of modal-->

<!--table-->
<div class="container">
  <table class="table table-responsive table-striped">
    <tr>
      <th>id</th>
      <th>name</th>
      <th>year</th>
      <th>major</th>
      <th>address</th>
      <th>email</th>
      <th>phone</th>
    </tr>
  </table>
<div>
<!--end of table-->

这是打字稿文件：

//app.component.ts

import { Component } from '@angular/core';
import { TemplateRef } from '@angular/core';
import { BsModalService } from 'ngx-bootstrap/modal';
import { BsModalRef } from 'ngx-bootstrap/modal/modal-options.class';
import { NgIf } from '@angular/common';

 @Component({
  selector: 'app-root',
  styleUrls:['app.component.css'],
  templateUrl:'app.component.html',
  //template:`<h1 align="center">template</h1>`
})

export class AppComponent 
{
  title = 'title';

}

我需要做的只是将用户输入插入到表格行中。如果需要更多代码段，请告诉我。

您可以在app.component.ts文件中声明自定义对象数组，如下所示

import { Component } from '@angular/core';
import { FormsModule } from '@angular/forms';

@Component({
  selector: 'app-root',
  template: `
  <div class="container">
  <table class="table table-responsive table-striped">
    <tr>
      <th>id</th>
      <th>name</th>
      <th>year</th>
    </tr>
    <tr *ngFor="let row of rows">
      <td>{{row.id}}</td>
      <td>{{row.name}}</td>
      <td>{{row.year}}</td>
    </tr>
  </table>
  <div>

  <hr />
  <input type="text" [(ngModel)]="id" placeholder="id" />
  <input type="text" [(ngModel)]="name" placeholder="name" />
  <input type="text" [(ngModel)]="year" placeholder="year" />

  <button (click)="buttonClicked()">Click to Insert New Row</button>
  `,
  styles: []
})
export class AppComponent {
  title = 'app';

  public id: number;
  public name: string;
  public year: number;
  public rows: Array<{id: number, name: string, year: number}> = [];

  buttonClicked() {
    this.rows.push( {id: this.id, name: this.name, year: this.year } );

    //if you want to clear input
    this.id = null;
    this.name = null;
    this.year = null;
  }
}

// html data//   

 <table border="1">
   <thead>
      <tr>
        <th>Type</th>
        <th>Name</th>
        <th>Batters</th>
        <th>Toppings</th>
      </tr>
   </thead>
   <tbody>
      <tr *ngFor="let data of Newjson;">
        <td >
          {{data.type}}  
        </td>
        <td>
              {{data.name}}  
          </td>
          <td>
               <ul *ngFor="let item of data.batters.batter;" [ngClass]="{'devils-find':item.type==='Devil\'s Food'}">
                 <li [ngClass]="item.type">
