I'm using the bodymovin script in my project. Even though some of my animated SVG's are rendering in the browser, I'm still getting this error
Uncaught TypeError: Cannot read property 'appendChild' of undefined

According to this answer, I figure I should have the bodymovin script run after everything on the page has loaded. I've updated the code, taking into account the new suggestions
index.html
<!doctype html>
<html lang="en">
<head>...</head>
<body>...
<div class="full-app-body">
<app-root></app-root>
</div>
<script src="https://cdnjs.cloudflare.com/ajax/libs/bodymovin/4.10.2/bodymovin.min.js"></script>
</body>
</html>
app.component.ts
import { Component, ElementRef, OnInit, AfterViewInit } from '@angular/core';
import { Router, ActivatedRoute, RouterOutlet, Routes } from '@angular/router';
import { BrowserModule } from '@angular/platform-browser';
import { NgClass, CommonModule } from '@angular/common';
...
export class AppComponent implements AfterViewInit {
constructor(public router: Router, private elementRef: ElementRef) {}
...
ngAfterViewInit() {
const s = document.createElement('script');
s.type = 'text/javascript';
s.src = '/assets/js/animations.js';
// this.elementRef.nativeElement.appendChild(s);
document.body.appendChild(s);
}
app.component.html
<div id='bm'></div>
animations.js
var animation = bodymovin.loadAnimation({
container: document.getElementById('bm'),
renderer: 'svg',
loop: true,
autoplay: true,
path: './assets/images/ani/fatigue-data.json'
});
as far as i understand the issue is with the line
this.elementRef.nativeElement.appendChild(s);.You are trying to append something to a unknown element.U should get reference to the element you are trying to attach the script to first. Since its just a matter of adding a script,try the following codeHope this will help
update
Since you are using angular 4,you can use Renderer2 for solving your purpose as suggested here
