Why is the event not passed when calling two functions via onClick?

Question

JavaScript

When calling two functions via onClick error: "Cannot read property 'preventDefault' of undefined"

onClick={(e) => {onClickFunc(idx, e); handlerChangeTab(idx);}}

onToggleTab = (val, e) => {
        e.preventDefault();

        this.setState(() => {
            return {
                activeTab: val
            }
        })
    };

Answer 1

Do it through the handler

handleClick(e, idx) {
   onClickFunc(idx, e);
   handlerChangeTab(idx);
}
