How do I prevent the remove button from submitting t

Answer 1

Just add e.preventDefault(); in your method should prevent your page from submitting forms.

function myFunc(e){
       e.preventDefault();
}

According to the MDN Web Docs

The preventDefault () method of the Event interface tells the user agent that if the event is not explicitly processed, its default action should not be taken into account as it would normally be. The event continues to propagate as usual, unless one of its listeners calls stopPropagation () or stopImmediatePropagation (), either of which terminates the propagation.
