Question

我已经创建了一个输入组件和一个datepicker组件。我的输入组件在类型参数的基础上为文本（数字ecc）创建了正确的输入标签。对于日期选择器，我创建了另一个托管ngb-datepicker的组件。输入组件：

docker build -t test --build-arg var_env="New Env Value" .

Datepicker组件：

    <div class="input-group input-group-sm">
    <ng-container [ngSwitch]="type">
      <ng-container *ngSwitchCase="'date'">        
        <app-date-picker [id]="object.id" [name]="object.id" [disabled]="disabled" (focus)="focus()" (focusout)="focusout()" [(ngModel)]="value"></app-date-picker>
      </ng-container>
<div class="input-group-append" #ref>
  <span *ngIf="unit" class="input-group-text" [ngClass]="{
    'disabled': disabled, 
    'focused': focused}">{{unit}}</span>
  <span class="input-group-text" [ngClass]="{'focused': focused}" *ngIf="!disabled && !readonly && !isValidationOff">
    <app-quality-status #qualityStatus [objects]="[object]" [hide]="hideQualityStatus"></app-quality-status>
  </span>
</div>

<div class="input-group-append" #ref>
  <ng-content></ng-content>
</div>

使用此嵌套的输入组div，结果是我拥有一个控件，它不使用整个空间，而只使用一半。如果删除datepicker组件中的输入组，问题是我的按钮与文本框不对齐。

我该如何解决这类问题？

Answer 1

尝试将以下CSS添加到hello.component

:host {
  display: flex;
  flex: auto;
}

Answer 2

在<hello>组件中添加了两件事

input-group-append

class ='form-control'
style='padding:0px'，因为此填充会将输入内容稍微放在外面

相关的 app.component.html ：

<div class="row form-group form-group-sm">
    <div class="col-md-12">
        simple input box - works !
    <div class="input-group input-group-sm">  
            <input type="number" class="form-control" placeholder="">
            <div class="input-group-append" #ref>
                <span class="input-group-text" >Unit</span>
                <span class="input-group-text">
          <span class="help">
            Help
          </span>
                </span>
            </div>
            <div class="input-group-append" #ref>
                <ng-content></ng-content>
            </div>
        </div>
    </div>

    <div class="col-md-12">
    Only my custom component - works !
        <hello name="{{ name }}"></hello>
    </div>

    <div class="col-md-12">
    My custom component in a input-group - fails !
<div class="input-group input-group-sm">
            <hello name="{{ name }}" class='form-control' style='padding:0px' ></hello>
            <div class="input-group-append" #ref>
                <span class="input-group-text" >Unit</span>
                <span class="input-group-text">
          <span class="help">
            Help
          </span>
                </span>
            </div>
            <div class="input-group-append" #ref>

</div>
