The onmouseout event activates when the mouse is moved off an element. The event can be specified as a JavaScript expression or the name of a JavaScript function.
If an expression is used, the JavaScript keyword this refers to the element.
If the name of a function is used, the function will receive 2 parameters when called:
- The browser event object; this object can be used to determine the mouse coordinates
- A reference to the element
Example:
The following example highlights an element in yellow when the user hovers the mouse over it.
onmouseover: this.style.backgroundColor = "yellow";
onmouseout: this.style.backgroundColor = "";
