onmouseover usage example 1

In the following example, we will display a dialog box when the user moves the mouse pointer over the image:

<img src="/i/eg_mouse2.jpg" alt="mouse"onmouseover="alert(&#39;您的鼠标在图片上！&#39;)" />

Copy after login

Output: (Please move the mouse pointer over the image):

Visit W3School!

Placing the mouse on it will switch to another picture.

Attached code:

<html>
<head>
<script type="text/javascript">
function mouseOver()
{
document.getElementById(&#39;b1&#39;).src ="/i/eg_mouse.jpg"
}
function mouseOut()
{
document.getElementById(&#39;b1&#39;).src ="/i/eg_mouse2.jpg"
}
</script>
</head>
<body>
<a href="http://www.w3school.com.cn" onmouseover="mouseOver()" onmouseout="mouseOut()">
<img alt="Visit W3School!" src="/i/eg_mouse2.jpg" id="b1" />
</a>
