更改事件属性的值

Question

I trigger mousewheel event on one element and then I dispatch it to another element. It works perfectly fine, but now I am wondering if it is possible to change one property of event object to something else before dispatching?

I tried with this code, but obviously it does not work:

event.deltaY = 0;

el.dispatchEvent(new event.constructor(event.type, event));

Answer 1

As mentioned in the comments, the deltaY property is read-only. You're best bet would be to just create a variable that you can set and call upon when you need it.
