以下代码应该可以工作,但我似乎无法找到问题,为什么它不起作用,我用谷歌浏览器测试它
<html>
<head>
<script type="text/javascript" src="js/jquery_1.7.1_min.js"></script>
<script type="text/javascript">
$('#unos').click(function() {
$("#tre").attr('src', '/012/11/image2.jpg');
});
</script>
</head>
<body>
<img id="tre" class="aligncenter" title="images" src="/012/11/image1.jpg" alt="" width="940" height="207" />
<input id="unos" type="submit" name="change_src" value="change image" />
</body>
</html>
