Angular material 之 dialog 弹框实战

功能虽然简单，但是我更具官网上做出来是报错的，所以自己记录一下，希望可以帮到别人

首先，创建一个组件用于存放弹出按钮

在创建一个组件，存放弹出页面

直接上代码：

根：

非常重要，需要将弹出页面加载进去，不然弹不出来哦

在存放弹出按钮的地方：

总体：

// import { Component, OnInit } from '@angular/core';
import {MediaMatcher} from '@angular/cdk/layout';
import {ChangeDetectorRef, Component} from '@angular/core';

import {MatDialog} from '@angular/material/dialog';
import {NewsComponent} from './news/news.component';

export interface DialogData {
  animal: string;
  name: string;
}

@Component({
  selector: 'app-home',
  templateUrl: './home.component.html',
  styleUrls: ['./home.component.scss']
})
export class HomeComponent  {


  
  animal: string;
  name: string;

  mobileQuery: MediaQueryList;


  private _mobileQueryListener: () => void;

  constructor(changeDetectorRef: ChangeDetectorRef, media: MediaMatcher,
    public dialog: MatDialog //弹出框
    ) {
    this.mobileQuery = media.matchMedia('(max-width: 700px)');
    this._mobileQueryListener = () => changeDetectorRef.detectChanges();
    this.mobileQuery.addListener(this._mobileQueryListener);
  }


  openDialog(): void {  
   
    //弹出
    const dialogRef = this.dialog.open(NewsComponent, {
      width: '250px',
      data: {name: this.name, animal: this.animal}
    });

    dialogRef.afterClosed().subscribe(result => {
      this.animal = result;
    });
  }

 
}

页面很简单，一个button就行

要才弹出的页面ts

import { Component, OnInit,Inject} from '@angular/core';
import { DialogData } from 'src/app/components/dialog/dialog.component';
import { MatDialogRef, MAT_DIALOG_DATA} from '@angular/material/dialog';

@Component({
  selector: 'app-news',
  templateUrl: './news.component.html',
  styleUrls: ['./news.component.scss']
})
export class NewsComponent implements OnInit {

  constructor(
    public dialogRef: MatDialogRef,
    @Inject(MAT_DIALOG_DATA) public data: DialogData){
    }

  ngOnInit() {
  }


}

弹出页面自己写
