JavaScript 函数 setTimeout() 和 setInterval() 有时不起作用

Question

My own Google Chrome extension stops working after some time, because setTimeout() is not working in some cases.

Therefore the background script is not sending a message to the content script after some necessary delay.

I have found this problem by writing many console.log() statements.

As a solution i thought about using setInterval() until the message is sent to the content script:

var timer = setInterval(function() {
  clearInterval(timer);
  // Sending a message to the content script
}, 3000);

My code before, during and after setInterval() is quiet long, so i hope this code snippet is somehow enough.

Does anyone know in which cases these Timeouts or Intervals do not start?

Or are there any similar options i could use?

I have thought about using the Chrome Alarms API instead, but alarms can only be used once every minute and the minimum delay is one minute if i am not mistaken.

I never experienced any issue of setinterval or settimeout stops working. I guess there might be an issue in your code. If you are sure about the bug you should make a demo project and report bug on github.
