首先介绍一下实现的效果,就是单一表单能实现添加其他的,也能删除

代码如下:

<h5>动态添加表单</h5> <div class="form"> <div class="form-group form-group-sm" *ngFor="let i of login"> <label class="col-form-label">用户名</label> <input class="form-control" [(ngModel)]="i.username" value="{{i.username}}"> <label class="col-form-label">密码</label> <input class="form-control" [(ngModel)]="i.password" value="{{i.password}}"> <button class="btn btn-link" (click)="removeInput(i)">删除</button> </div> <button (click)="addInput()">增加</button> <button (dblclick)="dbclick()">双击</button> {{ login | json }} </div> username: any; id: number = 1; login:any = [{"username": "username" + this.id,"password": "pwd" + this.id}]; addInput() { console.log('点击'); console.log(this.login); let number = this.login.length + 1; this.login.push({"username": "username" + number, "password": "pwd" + number}); console.log(this.login); } removeInput(item) { console.log(item); let i = this.login.indexOf(item); console.log(i); this.login.splice(i, 1); }
