我一直在用头撞墙一个小时,试图弄清楚为什么我的主干代码不起作用。我终于通过切换使其工作:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>hello-backbonejs</title>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.1/jquery.min.js"></script>
<script src="http://ajax.cdnjs.com/ajax/libs/json2/20110223/json2.js"></script>
<script src="http://ajax.cdnjs.com/ajax/libs/underscore.js/1.1.6/underscore-min.js"></script>
<script src="http://ajax.cdnjs.com/ajax/libs/backbone.js/0.3.3/backbone-min.js"></script>
<script src="js/application.js"></script>
</head>
<body>
</body>
</html>
到:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>hello-backbonejs</title>
</head>
<body>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.1/jquery.min.js"></script>
<script src="http://ajax.cdnjs.com/ajax/libs/json2/20110223/json2.js"></script>
<script src="http://ajax.cdnjs.com/ajax/libs/underscore.js/1.1.6/underscore-min.js"></script>
<script src="http://ajax.cdnjs.com/ajax/libs/backbone.js/0.3.3/backbone-min.js"></script>
<script src="js/application.js"></script>
</body>
</html>
基本上移动脚本包括从head
到body
. 有人可以向我解释为什么这会起作用吗?
