Live reload JavaScript in Chrome
提问by Yang
I know you can live-edit JS from within the Source panel of Chrome Developer Tools, and I know there are systems for live-reloading of CSS, but can you live-reload JS from the source location (either a URL or local disk, or leveraging Workspaces somehow, or possibly even as a Chrome Developer Tools plugin)? In particular this would be insanely useful for CoffeeScript-to-JS setups.
我知道你可以在 Chrome 开发者工具的 Source 面板中实时编辑 JS，我知道有一些系统可以实时重新加载 CSS，但是你可以从源位置（URL 或本地磁盘，或以某种方式利用工作区，甚至可能作为 Chrome 开发人员工具插件）？特别是这对于从 CoffeeScript 到 JS 的设置非常有用。

It's surprisingly difficult to find anyone else trying to do this, considering how powerful it would be.
考虑到它的强大功能，很难找到其他人尝试这样做。
I've come closeto achieving automatic live reloading of JS without page refresh; here's what I do:
我已经接近实现 JS 的自动实时重新加载而无需刷新页面；这就是我所做的：
- In the inspector's
sourcestab, right click and choose "Add Folder to Workspace..." - Select to the local folder containing the
.jsyou want to sync and click[okay]. - Right click on the
.jsfile nested inside your newly-added workspace folder and choose "Map to Network Resource", then select the matching.jsfrom the page. - Make changes to the local
.jsfile using an external editor. - Click on the
.jsfile in the inspector, ensuring it has focus; this will trigger a "Recompilation and update" and your changes should be injected to the page.
- 在检查器的
sources选项卡中，右键单击并选择“将文件夹添加到工作区...” - 选择包含
.js您要同步的本地文件夹，然后单击[okay]。 - 右键单击
.js嵌套在新添加的工作区文件夹中的文件，然后选择“映射到网络资源”，然后.js从页面中选择匹配项。 .js使用外部编辑器更改本地文件。- 单击
.js检查器中的文件，确保它具有焦点；这将触发“重新编译和更新”，您的更改应注入页面。
Step 5 is the part that needs to be automated, somehow.
第 5 步是需要自动化的部分，不知何故。
If you combine this with a file-watcher that automatically bundles your app into a single .jsfile, you can come close to automatic reload without refreshing the page.
如果您将此与自动将您的应用程序捆绑到单个.js文件中的文件观察器结合使用，您可以接近自动重新加载而无需刷新页面。

Yes you can do that with grunt.js, or gulp.js. Other things like Codekit can do this, as can an add-on for Chrome called LiveReload.
是的，你可以用 grunt.js 或 gulp.js 做到这一点。Codekit 之类的其他东西可以做到这一点，Chrome 的附加组件 LiveReload 也可以做到这一点。
