jquery 怎么改变图片地址?

Question

<script type="text/javascript">
$(function() {
$("#toggle").click(function() {
$(this).text($("#content").is(":hidden") ? "了解更多请点" : "想要返回请点击击");
$("#content").slideToggle();
});
});
</script>
这是我用到的效果，点击展开或隐藏div我要在这个效果上加一个，点击时，图片的变化，
<img src="images/xian2.png" id="xian" width="1000" height="40" />
<img src="images/xian3.png" id="xian" width="1000" height="40" />
也就是点击xian2.png变成xian3.png，再点击时，xian3.png变成xian2.png

直接修改img的src就可以了$("xian").toggle(function () {$(this).attr("src","images/xian2.png");},function () {$(this).attr("src","images/xian3.png");});
