如何预加载JS文件？

Question

So I have a website, that has a configurator, where you can configure your own product. The configurator website needs additional .js files, like dist.js and libs.js . Both of those files are around 2mb's each.

My question is: how can I start downloading those files on the landing page, so that when user goes to /configuration.html , he already started downloading those files?

Answer 1

你需要在你的 HTML 中定义文件： <script src="yourfilename.js"></script>一定要把 .js 放在最后，否则它不会工作。
