I have been facing challenges trying to incorporate jQuery plugins into an Angular 4 TypeScript class. Despite multiple attempts, I have not been able to achieve my goal.
I tried various methods, but the HTML component view in Angular 4 does not seem to support jQuery ready/other events. How can I work around this limitation?
Currently, I have created a TypeScript class component and attempted to use a jQuery function within it, but so far, I have not been successful.
Below is the code snippet for reference:
import { Component, Input, ElementRef, HostBinding } from '@angular/core';
import * as $ from 'jquery';
import 'owl-carousel';
@Component({
selector: 'owl-carousel',
template: `<ng-content></ng-content>`
})
export class OwlCarouselComponent {
@HostBinding('class') defaultClass = 'owl-carousel';
@Input() options: Object;
$owlElement: any;
defaultOptions: any = {};
constructor(private el: ElementRef) {}
ngAfterViewInit() {
this.$owlElement = $(this.el.nativeElement).owlCarousel(this.defaultOptions);
}
ngOnDestroy() {
this.$owlElement.data('owlCarousel').destroy();
this.$owlElement = null;
}
}
The Visual Studio compiler displays a red error on this line:
this.$owlElement = $(this.el.nativeElement).owlCarousel(this.defaultOptions);
The error messages are as follows:
Severity Code Description Project File Line Suppression State
Error TS2339 Build:Property 'owlCarousel' does not exist on type 'JQuery'. On.Store.UI L:\ESaleStore\On.Store.UI\src\On.Store.UI\wwwroot\app\shared\OwlCarousel.component.ts 24

This is the content of my tsconfig.json file:
{
"compilerOptions": {
"target": "es5",
"module": "commonjs",
"moduleResolution": "node",
"sourceMap": true,
"emitDecoratorMetadata": true,
"experimentalDecorators": true,
"removeComments": false,
"noImplicitAny": false
},
"compileOnSave": true,
"exclude": [
"node_modules"
]
}
And here is my systemjs.config.js file configuration:
`/**
* System configuration for Angular samples
* Adjust as necessary for your application needs.
*/
(function (global) {
System.config({
paths: {
// paths serve as alias
'npm:': 'node_modules/'
},
map: {
app: 'app',
'@angular/core': 'npm:@angular/core/bundles/core.umd.js',
...
'owl-carousel': 'npm:@angular/owl.carousel/dist/owl.carousel.min.js'
},
meta: {
'owl-carousel': {
deps: ['jquery']
},
packages: {
app: {
main: './main.js',
defaultExtension: 'js'
},
rxjs: {
defaultExtension: 'js'
},
'angular-in-memory-web-api': {
main: './index.js',
defaultExtension: 'js'
}
}
});
})(this);
If anyone could offer guidance on how to resolve this issue, it would be greatly appreciated. Thank you.
