Truck Animation document.querySelector is null












0















I found this cool animation Truck Animation Button
but when I click on the "Ship" Button nothing happens.



I'm trying to implement the Typescript part, but all the document.querySelector are null.
I'm doing this OnInit() for example:
this.ripple = document.querySelector('[data-anim=ripple]');



And I always got the Error: "Cannot read property 'addEventListener' of null"



Can you help me? Thank you!

  • I already can fix this! Thank you! But now I have a problem... I got the error: this.getClickCoords is not a function :(

  • I think it's because the call to function btnHandler doesn't have any parameter and the function needs one. But I don't know what the parameter should be... Can you help me on this? Thank you :)
