error TS2339: Property 'modal' does not ex

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

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

Answer 2

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 3

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 4

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 5

Try installing the typings for Bootstrap DefinitelyTyped

typings install --global --save dt~bootstrap

Answer 6

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

npm install -D @types/bootstrap
