Angular PrimeNG Dialog Modal

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，非常容易。在这篇文章中，我们将知道如何在Angular PrimeNG中使用Dialog Modal。我们还将了解代码中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。

语法:

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

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

Angular PrimeNG对话模式属性：

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。
