Hello to all, welcome to therichpost.com. In this post, I will tell you, Add and Run Jquery in Angular 7.
Angular is growing very fastly and popular as single page application. Today I am working with Angular 7 and wanted to run some jquery methods and I succeed and I am sharing that tricks what I did on my app.
I have written so many post related to jQuery because jQuery is my first love and today I also use jQuery in my many projects.
Here is the working image, I added dynamic class to body tag with jQuery:
Here is the working and tested code and you need to follow and into your Angular 7 application:
1. Very first, you need to run below command into your terminal :
$ npm install jquery --save
2. Now, you need to add below jquery file path into your Angular 7 application angular.json file:
....
"scripts": ["node_modules/jquery/dist/jquery.js"]
....
3. Now you need to add below code into your app.component.ts file:
import * as $ from 'jquery';
export class AppComponent {
ngOnInit() {
$('body').addClass('df');
}
}
4. In this end run your Angular 7 application and you will see, new class will be added to body tag.
if you have any query related to this post, then please do comment below or ask question.
Thank you,

HI Paparao, it seems like, you are jquery ui elements so you’re getting this error.
Try to use :
declare let $: any;
instead of
import * as $ from ‘jquery’;
———-or ————-
1 : Import jquery-ui-dist
npm install jquery jquery-ui-dist
2: Add scripts in angular-cli.json
“scripts”: [
“../node_modules/jquery/dist/jquery.min.js”,
“../node_modules/jquery-ui-dist/jquery-ui.js”
],
Thank you
That’s nice , great idea I will try to use it because you know not all UI plugins have angular7 implementation yet . So you are my hero ?
Thank you moustafa
ok it goes well
Thanks for your proposal
Great..
hello i want to ask if you tried to use Mapster or maphilight in Angular 7 to highlight areas in an image , as i am currently working on this and i faced some issues .
Thank you
You can show me your working example and you can tell me the issue coming in console?
This is the HTML code : it is for image mapping :
This is the component.ts file :
import {OnInit,Component} from ‘@angular/core’;
import { HttpClient } from ‘@angular/common/http’;
import * as jQuery from ‘jquery’;
declare var $: any;
@Component({
selector: ‘app-maphilight’,
templateUrl: ‘./maphilight.component.html’,
styleUrls: [‘./maphilight.component.scss’]
})
export class MaphilightComponent implements OnInit {
title = ‘web_ui’;
State: JSON;
ngOnInit(){
$(“map[name=map] area”).on(“click”, function(e){
e.preventDefault();
alert($(this).attr(‘coords’));
});
$(‘img’).mapster({mapKey: ‘room’});
}
there is no error in Console but this is not working correctly, because each area should be highlighted onclick , like in this example : http://jsfiddle.net/jamietre/jQG48/
I am using the latest version of Jquery .
Thank you for your time
.
Actually i am new to Angular …
this is my html code for mapping the image
and this is the component.ts
import {OnInit,Component} from ‘@angular/core’;
import { HttpClient } from ‘@angular/common/http’;
import * as jQuery from ‘jquery’;
declare var $: any;
@Component({
selector: ‘app-maphilight’,
templateUrl: ‘./maphilight.component.html’,
styleUrls: [‘./maphilight.component.scss’]
})
export class MaphilightComponent implements OnInit {
title = ‘web_ui’;
State: JSON;
ngOnInit(){
$(“map[name=map] area”).on(“click”, function(e){
e.preventDefault();
alert($(this).attr(‘coords’));
});
$(‘img’).mapster({mapKey: ‘room’});
}
i wanted to use mapster API to trigger highlight or selection onclick on each area like in this example http://jsfiddle.net/jamietre/nM7kq/
and i am not getting any error but it doesn’t work correctly , onclick nothing is selected or highlighted even when i remove the alert giving the coordinates.
Thank you in advance for your time
you can email me : therichposts@gmail.com
No need to use: import * as jQuery from ‘jquery’;
Also you need to add mapster also.
Thank you , You’re right the error was that i haven’t added the mapster plugin and it is fixed now.
wow that is great..
thank you
short and useful post
Thank you Yusuf
