How to use javascript libraries in Angular 2 Project

Question

I have a library which has a function structure like this..

$.fn.et_menu = function ( options ) {
var settings = $.extend({
type: "default", // can be columns, default, mega, combined
animTime: 250,
openByClick: true,
delayTime: 0
}, options );

which should be called like

$('.menu.side-menu').et_menu({
type: "default",
delayTime: 0
});

Any help.. how to integrate this in Angular..

Ive included the library in my index.html file and did

declare var et_menu: any;

in my component.ts file..

Any help would be rally greatful.

You have included the library on your index.html file... and? What happened? How should runtime know that et_menu is some property of object fn of object $? Have you tried window["$"].fn.et_menu? — Eduard Lepner

Its angular 2, Ive made jquery workable, but cannot figure how to call function $('.menu.side-menu').et_menu({ type: "default", delayTime: 0 }); Its saying Property 'et_menu' does not exist on type 'JQuery<HTMLElement>'. — Hari Babu

Step One

npm install jssha --save [using jssha for this demo]

It it is your own custom file place it in the scripts array of angular-cli.json skip this step 1

Step two

Add the jssha scripts file in .angular-cli.json file
"scripts": [ "../node_modules/jssha/src/sha.js" ]

Step three Adding a var in component to be used as a global variable

//using external js modules in Angular Component
declare var jsSHA: any; // place this above the component decorator
shaObj:any;
hash:string;
this.shaObj = new jsSHA("SHA-512", "TEXT");
this.shaObj.update("This is a Test");
this.hash = this.shaObj.getHash("HEX")

Take a look @ this link. It has a working example and a question for the same with typings and without it.

I guesa you need to add two variables one for jquery and other for et then it will work

Hari Babu Over a year ago

$('.menu.side-menu').et_menu({ type: "default", delayTime: 0 });

In case of normal page we do something like.. $('.menu.side-menu').et_menu({ type: "default", delayTime: 0 });
