Mouse enter and mouse leave events doesn't work with mouse move event


I'm trying to create a custom cursor and detect the hover on some elements but the mouse enter and mouse leave event doesn't work properly when I uncomment the 2 lines in the mouse move event. However, It works when I delete the transform property of my cursor for an unkown reason.

I tried to subtract the half of the size of my cursor in my mouse move event, instead of having the transform property but I have the same result.

const cursor = document.querySelector(".cursor");
const elHover = document.querySelectorAll("img");

let mouse = {
  x: undefined,
  y: undefined,
};

document.addEventListener("mousemove", (e) => {
  mouse.x = e.pageX;
  mouse.y = e.pageY;
  // cursor.style.top = e.pageY + "px";
  // cursor.style.left = e.pageX + "px";
});

elHover.forEach((element) => {
  element.addEventListener("mouseenter", (e) => {
    // console.log("enter");
    document.querySelector("body").style.backgroundColor = "red";
  });

  element.addEventListener("mouseleave", (e) => {
    // console.log("leave");
    document.querySelector("body").style.backgroundColor = "blue";
  });
});

  margin: 0;

.cursor {
  width: 40px;
  height: 40px;
  position: absolute;
  border-radius: 50%;

  transform: translate(-50%, -50%);
}

Solution

  • Add pointer-events:none to cursor element's css.

    The pointer-events property allows for control over how HTML elements respond to mouse/touch events – including CSS hover/active states, click/tap events in Javascript, and whether or not the cursor is visible.

    the prime use case for pointer-events is to allow click or tap behavior to “pass through” an element to another element below it on the Z axis.
