Last Updated :
02 Feb, 2023
Angular PrimeNG is an open-source framework with a rich set of native Angular UI components that are used for great styling and this framework is used to make responsive websites with very much ease. In this article, we will see how to use the BlockUI component Verification in Angular PrimeNG.
The BlockUI component is used to block the component or the whole page. In BlockUI verification, we will verify whether the page or the component is blocked or not.
Syntax:
<p-blockUI [blocked]="gfg"></p-blockUI>
Creating Angular application & module installation:
Step 1: Create an Angular application using the following command.
ng new appname
Step 2: After creating your project folder i.e. appname, move to it using the following command.
cd appname
Step 3: Install PrimeNG in your given directory.
npm install primeng --save
npm install primeicons --save
Project Structure: It will look like the following:

Example 1: In this example, we will see the basic usage of Angular PrimeNG BlockUI Verification.
HTML
< div style = "width:80%" >
< h1 style = "color: green;" >
GeeksforGeeks
</ h1 >
< h2 >
Angular PrimeNG BlockUI Verification
</ h2 >
< p-blockUI [blocked]="gfg"></ p-blockUI >
< button type = "button" pButton pRipple
label = "Click here to block"
(click)="geeks()">
</ button >
</ div >
|
Javascript
import { Component } from "@angular/core" ;
@Component({
selector: "app-root" ,
templateUrl: "./app.component.html" ,
})
export class AppComponent {
gfg: boolean = false ;
geeks() {
this .gfg = true ;
setTimeout(() => {
this .gfg = false ;
}, 3000);
}
}
|
Javascript
import { NgModule } from "@angular/core" ;
import { BrowserModule }
from "@angular/platform-browser" ;
import { FormsModule } from "@angular/forms" ;
import { BrowserAnimationsModule }
from "@angular/platform-browser/animations" ;
import { AppComponent } from "./app.component" ;
import { ButtonModule } from "primeng/button" ;
import { BlockUIModule } from "primeng/blockui" ;
import { PanelModule } from "primeng/panel" ;
@NgModule({
imports: [
BrowserModule,
BrowserAnimationsModule,
BlockUIModule,
ButtonModule,
PanelModule,
FormsModule,
],
declarations: [AppComponent],
bootstrap: [AppComponent],
})
export class AppModule { }

Example 2: In this example, we will block a panel component rather than a complete page.
HTML
< div style = "width:80%" >
< h1 style = "color: green;" >
GeeksforGeeks
</ h1 >
< h2 >
Angular PrimeNG BlockUI Verification
</ h2 >
< button type = "button" pButton pRipple
label = "Click Here to Block"
(click)=" gfg = true ">
</ button >
< button type = "button" pButton pRipple
label = "Click Here to Unblock"
(click)=" gfg = false ">
</ button >
< p-blockUI [target]="geeks"
[blocked]="gfg">
< i class = "pi pi-lock"
style = "font-size: 3rem" ></ i >
</ p-blockUI >
< p-panel #geeks header = "BlockUI"
styleClass = "p-mt-4" >
< p class = "p-m-0" >
