imageMapster在懸停時未顯示alt img

Question

這就是我所擁有的。 我遵循了imagemapster絕對初學者教程，但仍然無法在懸停或單擊時將其替換為其他圖像。 它表明它是一個鏈接，並且光標在懸停時更改。

<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>

<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>

對不起，對於新手問題，我仍在學習:)謝謝！

該問題的原因是jquery的版本。 我們必須使用舊版本。
