imageMapster在悬停时未显示alt img

Question

这就是我所拥有的。 我遵循了imagemapster绝对初学者教程，但仍然无法在悬停或单击时将其替换为其他图像。 它表明它是一个链接，并且光标在悬停时更改。

<script src="script/jquery-2.1.0.min.js"></script>
<script src="script/jquery.imagemapster.js"></script>

<div id="knollnav">
<img id="knollnav_img" src="GFX/knollingbw.jpg"  usemap="#knoll" />
<map name="knoll">

</map>
</div>


<script>
$(document).ready(function ()
{
$('#knollnav_img').mapster({
singleSelect : true,
render_highlight : { altImage : 'GFX/knolling.jpg' },
 mapKey: 'student',
fill : true, altImage : 'GFX/knolling.jpg',
fillOpacity : 1,
});
});
</script>

对不起，对于新手问题，我仍在学习:)谢谢！

该问题的原因是jquery的版本。 我们必须使用旧版本。
