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);}
