Question

Which of the following statements will call the function paint every time the mouse is moved?

a. onMouseMove(paint);
b. addEventListener('mousemove', paint);
c. mouseMove(paint);
d. paint.onMouseMove();

Answer 1

The JavaScript statement to call the function 'paint' on a mouse move event is `addEventListener('mousemove', paint)`. This method attaches an event listener that calls the 'paint' function each time the mouse is moved over the element it's attached to.

Step-by-step explanation:

The statement that will call the function paint every time the mouse is moved is b. addEventListener('mousemove', paint). This JavaScript method is used to attach an event listener to an element. Whenever the specified event (mousemove) occurs on the element, the attached function (paint) is called. The other options provided are either incorrect syntax or do not achieve the stated goal of calling the paint function on a mouse move.
