問題如下1 這段代碼哪里錯了為什么沒有效果<!DOCTYPE html><html>
<head>
<meta charset="UTF-8">
<title>filter和not</title>
<script type="text/javascript" src="js/jquery-1.10.1.min.js" ></script>
</head>
<body>
<div class"box">
123 </div>
<div>
456 </div>
<script>
$('div').filter('.box')css('background','red');//有問題
$('div').not('.box')css('background','red');//有問題
</script>
</body></html>2 has這里又哪里錯了<!DOCTYPE html><html>
<head>
<meta charset="UTF-8">
<title>has</title>
<script type="text/javascript" src="js/jquery-1.10.1.min.js" ></script>
</head>
<body>
<div class="box">
<span class="box1">123</span>
<div>456</div>
</div>
<script>
$('.box').has('.box1').css('background','aqua')//問題
</script>
</body></html>
