这是我的代码:
<html>
<head>
<script type="text/javascript" language="javascript" src="jquery-1.7.1.js"></script>
<script type="text/javascript" language="javascript">
$(document).ready(function(){
alert('hei');
});
</script>
</head>
<body>
<input type="button" id="btn" />
</body>
</html>
我在$(document).ready
. 我也收到此错误:Uncaught SyntaxError: Unexpected token ILLEGAL
