我正在使用 asp mvc，我需要使用 spin.js，但无法正常工作。这是我正在使用的代码。
<!DOCTYPE html>

<title>spin.js example</title>
<script src="//cdnjs.cloudflare.com/ajax/libs/spin.js/1.2.7/spin.min.js"></script>
</head>
<body>
<div id="foo"></div>
<script>
var opts = {
lines: 10, // The number of lines to draw
length: 7, // The length of each line
width: 4, // The line thickness
radius: 10, // The radius of the inner circle
corners: 1, // Corner roundness (0..1)
rotate: 0, // The rotation offset
color: '#000', // #rgb or #rrggbb
speed: 1, // Rounds per second
trail: 60, // Afterglow percentage
shadow: false, // Whether to render a shadow
hwaccel: false, // Whether to use hardware acceleration
className: 'spinner', // The CSS class to assign to the spinner
zIndex: 2e9, // The z-index (defaults to 2000000000)
top: 25, // Top position relative to parent in px
left: 25 // Left position relative to parent in px
};
var target = document.getElementById('foo');
var spinner = new Spinner(opts).spin(target);
</script>
</body>
</html>
但是当我运行它时，这一行显示了一个异常
var spinner = new Spinner(opts).spin(target);
消息是
"Spinner is not defined"
关于如何解决这个问题有什么想法吗？
最佳答案
使用自旋库的完全限定路径，将此处插入 StackOverflow 代码片段时似乎工作正常(字面意思是复制您的问题，没有额外的修改)。这可能表明您的代码存在其他问题(这是整个页面)还是您的浏览器缓存了导致问题的内容。
