Angular PrimeNG Dialog 基础

Angular PrimeNG是一个开源框架，拥有丰富的原生Angular UI组件，可用于出色的造型，该框架可用于制作响应式网站，非常方便。在这篇文章中，我们将知道如何在Angular PrimeNG 中使用Dialog Basic。我们还将了解代码中将要使用的属性及其语法。

Dialog组件用于制作一个包含一些内容的组件，在一个叠加窗口中显示。

Angular PrimeNG对话框的基本属性：

header。它是对话框的标题文本。它是字符串数据类型，默认值为空。
visible。它指定了对话框的可见性。它是布尔数据类型，默认值为false。
style。它用于设置组件的内联风格。它是一个对象数据类型，默认值为空。
styleClass。它用于设置组件的风格类。它是字符串数据类型，默认值为空。

语法:

<p-dialog
      header="...."
      [style]="{width: '...vw'}"
      [(visible)]="...">  
</p-dialog>

<p-button 
      (click)="..." 
      label="....">
</p-button>

创建Angular应用程序和模块安装。

第1步：使用以下命令创建一个Angular应用程序。

ng new appname

第2步：创建你的项目文件夹即appname后，使用以下命令移动到它。

cd appname

第3步：在你给定的目录中安装PrimeNG。

npm install primeng --save
npm install primeicons --save

项目结构：执行上述步骤后，项目结构将如下所示。

运行下面的命令可以看到输出。

ng serve --open

  constructor(private primengConfig: PrimeNGConfig) {}
  
  ngOnInit() {
    this.primengConfig.ripple = true;
  }
  
  BasicShow: boolean = false;
  
  showDialog() {
    this.BasicShow = true;
  }
}

import { NgModule } from '@angular/core';
import { BrowserModule } 
    from '@angular/platform-browser';
import { BrowserAnimationsModule } 
    from '@angular/platform-browser/animations';
import { AppComponent } from './app.component';
import { DialogModule } from 'primeng/dialog';
import { ButtonModule } from 'primeng/button';
  
@NgModule({
