我正在通过常见问题解答中提到的google-code-prettify
CDN 使用这里
是突出显示代码的功能。现在我有问题<script src="https://cdn.rawgit.com/google/code-prettify/master/loader/run_prettify.js"></script>
prettyPrint()
prettyPrint()
当我调用此函数时,它说未定义 cdn 在页面加载并突出显示语法时自动调用此函数,但加载后我正在更改代码内容,然后我希望它再次突出显示。但我无法做到这一点prettyPrint()
。
我自己托管google-code-prettify
,然后我使用prettyPrint()
它并且工作正常但是当我在更改代码后调用此函数时没有任何反应,它不会突出显示我的语法
这是我正在使用的代码
