javascript中amplify.js的cdn回退代码

Question

我知道以下代码用于将jquery从cdn回退到本地。

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.2.6/jquery.min.js"></script>
<script>
if (!window.jQuery) {
    document.write('<script src="/path/to/your/jquery"></script>');
}
</script>

amplify.js javascript回退的类似代码是什么？

Answer 1

看起来cdnjs正在托管它

<script src="//cdnjs.cloudflare.com/ajax/libs/amplifyjs/1.1.0/amplify.min.js"></script>
<script>
if (!window.amplify) {
    document.write('<script src="/path/to/your/amplifyjs"></script>');
}
</script>
