The mouseout
event is fired at an Element
when a pointing device (usually a mouse) is used to move the cursor so that it is no longer contained within the element or one of its children.
mouseout
is also delivered to an element if the cursor enters a child element, because the child element obscures the visible area of the element.
Use the event name in methods like addEventListener()
, or set an event handler property.
addEventListener("mouseout", (event) => {});
onmouseout = (event) => {};
This interface also inherits properties of its parents, UIEvent
and Event
.

Returns the horizontal coordinate of the event relative to the current layer.
-
MouseEvent.layerY
Non-standard Read only
-
Returns the vertical coordinate of the event relative to the current layer.
-
MouseEvent.metaKey
Read only
-
Returns true
if the meta key was down when the mouse event was fired.
-
MouseEvent.movementX
Read only
-
The X coordinate of the mouse pointer relative to the position of the last mousemove
event.
-
MouseEvent.movementY
Read only
-
The Y coordinate of the mouse pointer relative to the position of the last mousemove
event.
-
MouseEvent.offsetX
Read only
-
The X coordinate of the mouse pointer relative to the position of the padding edge of the target node.
-
MouseEvent.offsetY
Read only
-
The Y coordinate of the mouse pointer relative to the position of the padding edge of the target node.
-
MouseEvent.pageX
Read only
-
The X coordinate of the mouse pointer relative to the whole document.
-
MouseEvent.pageY
Read only
-
The Y coordinate of the mouse pointer relative to the whole document.
-
MouseEvent.relatedTarget
Read only

MouseEvent.screenX
Read only
-
The X coordinate of the mouse pointer in global (screen) coordinates.
-
MouseEvent.screenY
Read only
-
The Y coordinate of the mouse pointer in global (screen) coordinates.
-
MouseEvent.shiftKey
Read only
-
Returns true
if the shift key was down when the mouse event was fired.
-
MouseEvent.mozInputSource
Non-standard Read only
-
The type of device that generated the event (one of the MOZ_SOURCE_*
constants). This lets you, for example, determine whether a mouse event was generated by an actual mouse or by a touch event (which might affect the degree of accuracy with which you interpret the coordinates associated with the event).
-
MouseEvent.webkitForce
Non-standard Read only
-
The amount of pressure applied when clicking.
-
MouseEvent.x
Read only

Alias for MouseEvent.clientX
.

MouseEvent.y
Read only

The following examples show the use of the mouseout
event.
The following example illustrates the difference between mouseout
and mouseleave
events. The mouseleave
event is added to the <ul>
to color the list purple whenever the mouse exits the <ul>
. mouseout
is added to the list to color the targeted element orange when the mouse exits it.
When you try this out, you'll find that mouseout
is delivered to the individual list items, while mouseleave
goes to the overall list, courtesy of the hierarchy of the items and the fact that list items obscure the underlying <ul>
.
HTML
<ul id="test">
<li>item 1</li>
<li>item 2</li>
<li>item 3</li>
</ul>
JavaScript
const test = document.getElementById("test");
test.addEventListener(
"mouseleave",
(event) => {
event.target.style.color = "purple";
setTimeout(() => {
event.target.style.color = "";
}, 1000);
},
false,
);
test.addEventListener(
"mouseout",
(event) => {
event.target.style.color = "orange";
setTimeout(() => {
event.target.style.color = "";
}, 500);
},
false,
);
