本文實例講述了JS使用oumousemove和oumouseout動態改變圖片顯示的方法。分享給大家供大家參考。具體如下：
鼠標放到圖片上時圖片會自動變大，鼠標離開圖片還原
<!DOCTYPE html>
<html>
<head>
<script>
function bigImg(x)
{
x.style.height="64px";
x.style.width="64px";
}
function normalImg(x)
{
x.style.height="32px";
x.style.width="32px";
}
</script>
</head>
<body>
<img onmouseover="bigImg(this)" onmouseout="normalImg(this)"
border="0" src="smiley.gif" alt="Smiley" width="32" height="32">
<p>The function bigImg() is triggered when the user moves
the mouse pointer over the image.</p>
<p>The function normalImg() is triggered when the mouse
pointer is moved out of the image.</p>
</body>
</html>
希望本文所述對大家的javascript程序設計有所幫助。
