Prevent javascript from being cached in browser

I'm currently working on a webapp and the Javascript is revised fairly often. However, the changes don't occur until the browser cache is refreshed manually. Is there a way to impleme开发者_如何转开发nt cache-refreshing automatically through code for Chrome? Thanks.

You can put something like ?2352352 at the end of your JS file. So something like

<script src='myfile.js?20457207'></script>

Where the number randomizes, forcing the browser to think it's a different file.
