Angular 6，Materialize：初始化javascript

Question

I am new to Angular and Materialize. I am trying to initialize a carousel within my Angular component.

Materialize mentions three ways:

M.AutoInit();

or

document.addEventListener('DOMContentLoaded', function() {
    var elems = document.querySelectorAll('.carousel');
    var instances = M.Carousel.init(elems, options);
  });

or

  $(document).ready(function(){
    $('.carousel').carousel();
  });

I have installed Materialize via node. I have both its CSS and JS as dependencies in my angular.json folder. The CSS styling works. I have tried these three methods within my ngOnInit lifecycle hook within my component. "M" is not recognized. I tried importing materialize:

import { materialize } from '../../../node_modules/materialize-css'

and

let m = materialize;

But this hasn't worked either.

I then installed jquery as a depedency and tried that method, but that doesn't seem to work either.

Answer 1

You should use the Materialize for Angular library. Asking how to use jQuery with Angular can get you a lot of downvotes.

Answer 2

• import OnInit from @angular/core library

• declare const M: any; underneath imports

• fire the M.AutoInit() function in ngOnInit() lifecycle hook

Example (where the component name is MediaComponent):

import { Component, OnInit } from '@angular/core';

declare const M: any;

@Component({
  selector: 'app-media',
  templateUrl: './media.component.html',
  styleUrls: ['./media.component.scss']
})
export class MediaComponent implements OnInit {

  constructor() { }

  ngOnInit() {
    M.AutoInit();
  }

}

Answer 3

import { Component, OnInit } from '@angular/core'; declare var M: any;
