我正在尝试使用 spin.js 库来显示加载动画。但是，关闭 spin.js developer example我似乎无法让它工作/出现；当我在 Firefox 中打开我的 html 文件时，空的 div 标签很明显。
这是我的代码 (spinnertest.html):
<html>
<head>
<script src="spin.min.js">
var opts = {
lines: 13, // 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: 'auto', // Top position relative to parent in px
left: 'auto' // Left position relative to parent in px
};
var target = document.getElementById("spinner");
var spinner = new Spinner(opts).spin(target);
</script>
</head>
<body>
<div id="spinner">
</div>
</body>
感兴趣者的工作代码(需要同一目录中的 jquery-1.9.0.min.js 和 spin.min.js):
<html>
<head>
<script type="text/javascript" src="spin.min.js"></script>
<script type="text/javascript" src="jquery-1.9.0.min.js"></script>
<script type="text/javascript">
$(function() {
var opts = {
lines: 13, // 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: 'auto', // Top position relative to parent in px
left: 'auto' // Left position relative to parent in px
};
var target = document.getElementById("spinner");
var spinner = new Spinner(opts).spin(target);
});
</script>
</head>
<body>
<div id="spinner">
</div>
</body>
最佳答案
我不相信带有 src 属性的 script 标签内的代码会执行。如果您将代码更改为以下内容，它是否有效？
<script type="text/javascript" src="spin.min.js"></script>
<script type="text/javascript">
$(document).ready(function () {
var opts = ...
...
// all the code that you currently have between <script> and
// </script> goes here
});
</script>
