jQuery 签名无法在 Bootstrap 4 模式中重置

Question

I want to add some signature record on modal. But when I tried to clear the signature I got this error:

[Intervention] Ignored attempt to cancel a touchstart event with cancelable=false, for example because scrolling is in progress and cannot be interrupted.

I added event.cancelable in jquery touch but still same. The error gone but signature still there

Here's my code: CodePen.io

Answer 1

I forgot to add signature('clear');
