angular2 动态添加input输入框，
前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。
export class TComponent {
username: any;
id: number = 1;
login:any = [{"username": "username" + this.id,"password": "pwd" + this.id}];
addInput() {
var number = this.login.length + 1;
this.login.push({"username": "username" + number,"password": "pwd" + number});
}
removeInput(item) {
console.log(item);
let i = this.login.indexOf(item);
console.log(i);
this.login.splice(i,1);
}
}
<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)">Remove</button>
</div>
<button class="btn btn-link" (click)="addInput()">Add</button>
{{ login | json }}
</div> 原文链接：https://www.f2er.com/angularjs/148632.html
