Angular 为什么我得到未定义的输入字段

我有一个添加用户的函数 模型是：

export class User {
  public constructor (
    public firstName: string,
    public lastName:string,
    public email:string,
    public address: string
){}}

在用户组件中，我定义了函数addUser:

addUser(user:any, address:any){
    if (this.form.valid) { let newUser = new User([user["firstName"], user["lastName"], user["email"], user["address"]);}}

我得到一个新用户，其属性为“address=undefined”。

为什么？？？

即使我将地址添加到此.fb.group，也没有任何变化。 HTML文件太长，这是输入部分：

 <div class="tab-pane active" id="profile">                                                
                            <div class="form-group">
                                <label class="text-gray">First name :</label>
                                <input formControlName="firstName" class="form-control validation-field" type="text">
                                <small class="text-danger" *ngIf="form.controls.firstName.touched && form.controls.firstName.errors?.required">firstName is required</small>                              
                                <small class="text-danger" *ngIf="form.controls.firstName.touched && form.controls.firstName.errors?.minlength">firstName isn't long enough, minimum of 5 characters</small>
                            </div>
                            <div class="form-group">
                                <label class="text-gray">Last name :</label>
                                <input formControlName="lastName" class="form-control validation-field" type="text">
                                <small class="text-danger" *ngIf="form.controls.lastName.touched && form.controls.lastName.errors?.required">lastName is required</small>                              
                                <small class="text-danger" *ngIf="form.controls.lastName.touched && form.controls.lastName.errors?.minlength">lastName isn't long enough, minimum of 6 characters</small>
                            </div>  
<div class="tab-pane" id="address">
                            <div class="form-group">
                                <label class="text-gray">Address :</label>
                                <div class="input-group" >
                                    <div class="input-group-addon"><i class="fa fa-map-marker"></i></div>
                                    <input  formControlName="address" class="form-control validation-field" type="text">
                                    <small class="text-danger" *ngIf="form.controls.town.touched && form.controls.town.errors?.required">assress is required</small>                              
                                    <small class="text-danger" *ngIf="form.controls.town.touched && form.controls.town.errors?.minlength">address isn't long enough, minimum of 6 characters</small>
                                </div>
                            </div>

共享您的组件代码？您的this.fb.group包含名字、姓氏和电子邮件，没有地址您可以共享html吗？
