清除按钮作为指令或角度为2-8的组件

如何解决清除按钮作为指令或角度为2-8的组件

我想在所有输入上放置一个清晰的图标/按钮。是否可以将该组件用作具有清除按钮HTML的属性，因为该组件将在所有输入上用作属性选择器

基本上我想将以下代码作为指令或组件作为可重用的属性

import { Component,OnInit,Input } from '@angular/core';

@Component({
  selector: '[appClearInput]',templateUrl: './clear-input.component.html',styleUrls: ['./clear-input.component.scss'],})
export class ClearInputComponent implements OnInit {
  @input() appClearInput: any;
  @input() inputs: any;
  constructor() {
    // console.log(this.inputs);
  }

  ngOnInit(): void {}

  ngAfterViewInit() {
    setTimeout(() => {
      console.log(this.inputs);
    });
  }

  clearValue() {
    this.inputs.value = '';
  }
}`

//ClearInputComponent HTML
<button 
  mat-button
  matSuffix
  mat-icon-button
  aria-label="Clear"
  (click)="clearValue()"
>
  <mat-icon style="font-size: 18px;">close</mat-icon>
</button>
//Using component as attribute

 <mat-form-field fxFlex [ngClass.gt-xs]="'min-ctrl'">
            <input
              matInput
              type="text"
              placeholder="Invoice No"
              formControlName="invoiceNo"
              #inputpurchaseInvoiceNo
              maxlength="80"
              [appHighlight]="'yellow'"
              [appClearInput]="inputpurchaseInvoiceNo"
                       />

解决方法

        import {
      Component,OnInit,Input,ElementRef,Renderer2,ViewChild,AfterViewInit,HostListener,} from '@angular/core';
    
    @Component({
      selector: 'input[type="text"],input[type="password"],input[type="number"],input[type="text"][ngModel]',templateUrl: './clear-input.component.html',styleUrls: ['./clear-input.component.scss'],})
    export class ClearInputComponent implements AfterViewInit {
      constructor(private el: ElementRef,private renderer: Renderer2) {}
    
      ngAfterViewInit() {
        const clearInputBtn = document.getElementById(
          'food-name-val'
        ) as HTMLInputElement;
        this.renderer.appendChild(
          this.el.nativeElement.parentElement,clearInputBtn
        );
        this.renderer.listen(clearInputBtn,'click',() => {
          this.el.nativeElement.value = '';
        });
      }
    
      @HostListener('focus') onFocus() {
        this.el.nativeElement.select();
      }  
    }

<button
      #clearInputBtn
      id="food-name-val"
      mat-button
      matSuffix
      mat-icon-button
      aria-label="Clear"
      class="icon-close"
    >
      <mat-icon style="font-size: 18px;">close</mat-icon>
    </button>
