error TS2339: Property 'modal' does not exist on type 'JQuery'

Question

I'm using Typescript with AngularJS. I have a problem with modals using typed definition of jQuery library. I get the following error: 'error TS2339: Property 'modal' does not exist on type 'JQuery'.'

Version: jQuery library, version 1.10.x / 2.0.x Definitions: https://github.com/borisyankov/DefinitelyTyped

Code

$scope.delete = function (id) {
  Photo.get({id: id}, function(result) {
     $scope.photo = result;
     $('#deletePhotoConfirmation').modal('show');// error line 
  });
};

I'm referencing to jquery.d.ts in angular.d.ts

<reference path="../jquery/jquery.d.ts" />

and my global vendor reference file looks like:

<reference path='../vendor/types/angular/angular.d.ts' />
<reference path='../vendor/types/angular/angular-mocks.d.ts' />
<reference path='../vendor/types/jasmine/jasmine.d.ts' />

Answer 1

with newer versions of typescript (>v2 i believe):

npm install -D @types/bootstrap

Edit: As hughjdavey said in his comment, you also need the following import lines:

import * as bootstrap from "bootstrap";
import * as $ from 'jquery';

Answer 2

Your problem is caused by the lack of property with name modal in the jquery.d.ts file.

If you sure that this work in pure JS you can trick with it like this

$scope.delete = function (id) {
  Photo.get({id: id}, function(result) {
     $scope.photo = result;
     (<any>$('#deletePhotoConfirmation')).modal('show');
  });
};

Also, you can find additional d.ts file where this option has already been defined.

Try to consider this library that has already had modal option

Good Luck!

Answer 3

In my case I had to use

npm install -D @types/bootstrap

and then I had to import bootstrap

import * as bootstrap from 'bootstrap';

but most important step was to remove jquery

import * as $ from 'jquery';

otherwise it was giving me this error:

TypeError: $(...).modal is not a function

Answer 4

When I upgrade angular to version 9, I faced this issue.

Here are my solution, I shared for whom concerned.

Property 'modal' does not exist on type 'JQuery'

$('#ManualMinMaxModal').modal('show');

change to

($('#ManualMinMaxModal') as any).modal('show');

And

Property 'DataTable' does not exist on type 'JQuery'

$('#realTimeTable').DataTable()

change to

($('#realTimeTable') as any).DataTable()

With

!$.fn.DataTable.isDataTable('#realTimeTable')

change to

!($.fn as any).DataTable.isDataTable('#realTimeTable')

Updated:

cast to any sometime not work, and finally solution is change declare from import * as $ from 'jquery' to declare var $: any;

Answer 5

this work for me, i add in first row:
declare var $ :any;
this declare $ type is any ,

Answer 6

I could resolve it as follows:

import * as $ from "jquery";

($('#menuModal') as any).modal('toggle');

Answer 7

Try installing the typings for Bootstrap DefinitelyTyped

typings install --global --save dt~bootstrap

Answer 8

Just add

import * as bootstrap from "bootstrap";
import * as $ from "jquery";

in your app.module.ts

And install these packages

npm install @types/jquery --save-dev

npm install @types/bootstrap --save-dev

Answer 9

Solution for Angular 8+ versions :

Not working:

$('#deletePhotoConfirmation').modal('show');

Instead use this:

($('#deletePhotoConfirmation') as any).modal('show');

For Import :

import * as $ from 'jquery';

Good Luck

Answer 10

Yep, I too had to include both of these imports in order to make my app publishable by angular:

import * as bootstrap from "bootstrap";
import * as $ from "jquery";

I added them in the component that was using jQuery.

Answer 11

Did you add bootstrap.js to your angular.json?

"scripts": [
   "node_modules/jquery/dist/jquery.min.js",
   "node_modules/bootstrap/dist/js/bootstrap.min.js"
],

Answer 12

declare var $ :any;

This worked for me.
