Title
Body
I read about Background page and Content scripts at developer.chrome.com but I'm confused with them, I cannot understand when to use background scripts and when to use content scripts. For example: manifest.json : { "name": "Hello World", "version": "2.0", "manifest_version": 2, "background": { "scripts": ["background.js"] }, "content_scripts": [ { "matches": ["http://*/*", "https://*/*"], "js": ["js/myScript.js"] } ], "permissions": ["tabs", "http://*/*"], "browser_action": { "default_icon": "icon.png" } } If background.js is: // Called when the user clicks on the browser action. chrome.browserAction.onClicked.addListener(function(tab) { alert("test"); }); It works well, but if I put the same code above in myScript.js , it doesn't work. So I don't know which script should be located in background.js , and which should be located in content scripts.
