chrome extension Content Security Policy “Refused to execute inline event handler” error

在chrome extension 動態產生內容時,發生錯誤訊息:

Refused to execute inline event handler because it violates the following Content Security Policy directive: "script-src 'self'". Either the 'unsafe-inline' keyword, a hash ('sha256-...'), or a nonce ('nonce-...') is required to enable inline execution. Note that hashes do not apply to event handlers, style attributes and javascript: navigations unless the 'unsafe-hashes' keyword is present.


Note that inline event handlers are blocked as well:

HTMLCopy to Clipboard

<button id="btn" onclick="doSomething()"></button>

You should replace them with addEventListener calls:

JSCopy to Clipboard

document.getElementById("btn").addEventListener("click", doSomething);
