The onmouseout property returns the onMouseOut event handler code on the current element.

Syntax

element.onmouseout = event handling code

Example

<!doctype html>  
<html>  
<head>  
<title>onmouseover/onmouseout event example</title>  
<script type="text/javascript">  
    function initElement()  
    {  
        var p = document.getElementById("foo");  

        p.onmouseover = showMouseOver;
        p.onmouseout = showMouseOut;
    };  

    function showMouseOver()  
    {  
        var notice = document.getElementById("notice");
        notice.innerHTML = 'mouse over detected';
    }
    
    function showMouseOut()
    {
        var notice = document.getElementById("notice");
        notice.innerHTML = 'mouse out detected';
    }


</script>  
<style type="text/css">  
    #foo {  
    border: solid blue 2px;  
    }  
</style>  
</head>  
<body onload="initElement()";>
    <span id="foo">My Event Element</span>
    <p>mouve your mouse over and out the above element.</p>  
    <div id="notice"></div>
</body>  
</html>  

Notes

The mouseout event is raised when the mouse leaves an element (e.g, when the mouse moves off of an image in the web page, the mouseout event is raised for that image element).
