I am trying to use jQuery and jsGrid with my Angular 6 project, and it won't compile unless I comment offending part of code, and then once when it is compiled I comment and it works, but it gives error anyway. I am using Angular 6 CLI, IDE is Visual Studio Code, all latest versions. VS highlights jQuery alias i.e. $ sign as a problem
Here is structure.directive.ts (I have to comment whole ngOnInit to start server, then uncomment it):
import { Directive, ElementRef, OnInit } from '@angular/core';
@Directive({
selector: '[structure]'
})
export class StructureDirective implements OnInit {
clients = [
{ "Name": "Otto Clay", "Age": 25, "Country": 1, "Address": "Ap #897-1459 Quam Avenue", "Married": false },
{ "Name": "Connor Johnston", "Age": 45, "Country": 2, "Address": "Ap #370-4647 Dis Av.", "Married": true },
{ "Name": "Lacey Hess", "Age": 29, "Country": 3, "Address": "Ap #365-8835 Integer St.", "Married": false },
{ "Name": "Timothy Henson", "Age": 56, "Country": 1, "Address": "911-5143 Luctus Ave", "Married": true },
{ "Name": "Ramona Benton", "Age": 32, "Country": 3, "Address": "Ap #614-689 Vehicula Street", "Married": false }
];
countries = [
{ Name: "", Id: 0 },
{ Name: "United States", Id: 1 },
{ Name: "Canada", Id: 2 },
{ Name: "United Kingdom", Id: 3 }
];
constructor(private elementRef: ElementRef) { }
ngOnInit() {
window.$(this.elementRef.nativeElement).jsGrid({
width: "100%",
height: "400px",
inserting: true,
editing: true,
sorting: true,
paging: true,
data: this.clients,
fields: [
{ name: "Name", type: "text", width: 150, validate: "required" },
{ name: "Age", type: "number", width: 50 },
{ name: "Address", type: "text", width: 200 },
{ name: "Country", type: "select", items: this.countries, valueField: "Id", textField: "Name" },
{ name: "Married", type: "checkbox", title: "Is Married", sorting: false },
{ type: "control" }
]
})
}
}

ERROR in src/app/structure.directive.ts(26,12): error TS2339: Property '$' does not exist on type 'Window'.
How can I solve this?

This is a problem with the typescript types not with angular. Run this command
npm install @types/jquery --save-dev
or if you are using yarn:
yarn add @types/jquery
And then add this in a type declaration file aka somefile.d.ts
declare global {
interface Window {
$: JQueryStatic
}
}
This approach only makes the types available! You still have to import jquery somewhere.
alternatively you could import jquery. This will include the library itself and the types.
import * as $ from "jquery"
and use it without the window prefix.
