我不确定为什么这段代码不起作用。我想要实现的是我想点击按钮并突出显示一些文字。
<!doctype html>
<html>
<head>
<meta charset="UTF-8">
<title>the title</title>
<script type="text/javascript"
src="/jquery/jquery-1.3.2.min.js"></script>
<script type="text/javascript"
src="/jquery/jquery-ui-1.7.2.custom.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$("#button").click(function(){
$(".target").effect( "highlight",
{color:"#ffff00"}, 30000 );
});
});
</script>
</head>
<body>
<button id="button">Take Hint</button>
<p><span class="target">this text needs to highlight
</span></p>
</body>
</html>
