Angular PrimeNG表的选择模式

Angular PrimeNG表的选择模式

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,这个框架用于制作响应式网站,非常容易。这篇文章将向我们展示如何在Angular PrimeNG中使用表过滤功能。

Angular PrimeNG表选择在表组件中启用了单节点和多节点选择模式,这样我们就可以一次选择单个或多个表节点。因此,使用表格选择,我们可以使表格更加友好和高效。

Angular PrimeNG表选择属性:

  • selectionMode:这是一种选择模式,我们可以通过它来选择表的节点。

语法:

<p-table 
    #tableref
    selectionMode="single | multiple">

      <ng-template pTemplate="body">
        <tr [pSelectableRow]="row">
            ...
        </tr>
      </ng-template>
</p-table>
HTML

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
JavaScript

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
JavaScript

第3步在你给定的目录中安装PrimeNG。

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

项目结构:它将看起来像如下。
