如何在asp.net(C#)中使用javascript在已绘制的圆(孔)上绘制一个矩形。我在页面中将我的圆圈绘制为位图。应该在mousemove事件上绘制矩形。

在img标签中写下以下代码:
<img name="picture" src="Images/circle.jpg" alt="My Image"
onmouseover="document.picture.src=image2.src"
onmouseout="document.picture.src=image1.src" />
并且所需的javascript是:
<script language="Javascript" type="text/javascript">
image1 = new Image
image1.src = "Images/circle.jpg"
image2 = new Image
image2.src = "Images/squre.jpg"
</script>
