修复js“脚本错误" [英] Fixing js "Script error"
问题描述
我在实现一些简单的事情时遇到了困难:我在 http://localhost:3200 通过 ruby on rails，它使用 webpack-dev-server 在 http://localhost:8000 上提供的 javascript 文件.
I'm having difficulties implementing something simple: I have an index.html file served on http://localhost:3200 by ruby on rails, which uses a javascript file served on http://localhost:8000 by webpack-dev-server.
这就是我所拥有的:
<!doctype html>
<head>
<script crossorigin="anonymous" src="http://localhost:8000/app.js" />
</head>
<!-- ... -->
</html>
我的 app.js 文件发送时包含以下标头:
My app.js file is sent with, amongst others, the following header:
Access-Control-Allow-Origin: *
我想要的是能够覆盖 app.js 中的 window.onerror，并查看捕获的错误，而不是脚本错误".
What I want is to be able to override window.onerror in app.js, and see caught errors, rather than "Script error".
我错过了什么?
-- 编辑--因为它可能不够清楚:我的脚本确实加载了.对于那件事我没有任何疑问.我的问题是我需要报告发生在其他地方的错误，但我不能这样做，因为 app.js 中发生的任何错误都被报告为脚本错误"而不是更明确的错误.
-- edit -- Since it might not be clear enough: my script does load. I have no problem with that. My issue is that I need to report errors that happen to somewhere else, but I can't do that since any error that occurs in app.js is reported as "Script error" rather than something more explicit.
推荐答案
你使用的是什么 sourcemap (devtool)?
What sourcemap (devtool) are you using?
我遇到了这个问题，它从 eval-source-map 更改为 source-map 修复了它.
I was getting this issue, and it changing from eval-source-map to source-map fixed it.
