Question

这是我的代码，我不知道为什么，但是当我单击“提交”按钮时，我的formcontrolname没有发送值，并且我试图通过各种方式实现动态形式，因此这是一种方式。 FirstName和下拉列表中的点击值未收到，我的其他字段正在接收值
Dynamic-Forms.html

filterButton.leftAnchor.constraint(equalTo: menuButton.leftAnchor).isActive = true
filterButton.topAnchor.constraint(equalTo: menuButton.topAnchor).isActive = true
filterButton.rightAnchor.constraint(equalTo: menuButton.rightAnchor).isActive = true
filterButton.bottomAnchor.constraint(equalTo: menuButton.bottomAnchor).isActive = true

在usercheckedValue中，假设我有3个用户这是我的控制配置数组

<form [formGroup]="u2">
<div *ngFor="let userCheckedValueDetails of userCheckedValue">
<div *ngFor="let controlConfigDetails of controlConfig">
 <div class="form-group">
 <div *ngIf="controlConfigDetails.name === 'FirstName'">
      <span>{{userCheckedValueDetails.name}}</span>
      <input type={{controlConfigDetails.type}} name= {{controlConfigDetails.name}} placeholder={{controlConfigDetails.placeholder}}
        formControlName={{controlConfigDetails.formControlName}} value={{userCheckedValueDetails.name}} hidden>
    </div>

    <div *ngIf="controlConfigDetails.name === 'LastName' || controlConfigDetails.name === 'Email' || controlConfigDetails.name === 'Age' ||controlConfigDetails.name === 'Mobile'">
      <input type={{controlConfigDetails.type}} name={{controlConfigDetails.name}} class="form-control" placeholder={{controlConfigDetails.placeholder}}
        formControlName={{controlConfigDetails.formControlName}}>
    </div>

    <div class="dropdown" *ngIf="controlConfigDetails.name === 'State'">

        <input type={{controlConfigDetails.type}} name={{controlConfigDetails.name}} class="form-control" placeholder={{controlConfigDetails.placeholder}}
        formControlName={{controlConfigDetails.formControlName}} value={{StateDropDownValue}}>
        <button class="btn btn-primary dropdown-toggle" type="button" data-toggle="dropdown">{{StateDropDownValue}}
          <span class="caret"></span>
        </button>
        <ul class="dropdown-menu">
          <li *ngFor="let StateArray of StateName">
            <a (click)="StateDropDownValue = StateArray ; ">{{StateArray}} </a>
          </li>
        </ul>
      </div>
  </div>
</div>

<button type="submit" (click)="onFormGroupSubmit(u2,userCheckedValueDetails)">Submit</button>

我知道我错过了一些小错误，但是没有得到哪件事只是帮了我忙
