I want to write a program that when a do something on a chrome tab, other tab will do the same things.

For example, I enter some statements and click a button on a tab, others will do the same things.(All of them in the same website for sure)

The way came out of my mind, is recording the activates when I was do the things on a tab (Maybe save the record by a script file), and execute the script in the same time.

But I think this method is stupid because the performance may not be so good.

The other way is using the javascript to fulfill the task. But I'm not good at js, I don't know how to do that exactly.

Does anyone give me some keyword to search on google?

Thanks!
