google chrome extension - Why isn't my background script getting executed? -
i added simple background script chrome extension.
my manifest.json file:
{ "name" : "test extension", "version" : "1.0", "description" : "test extension.", "background" : { "scripts": ["background.js"] }, "devtools_page": "devtools.html", "permissions": ["http://*/*", "https://*/*"], "manifest_version": 2 } i go chrome://extensions , select background.js in inspect views.
it opens devtools go sources , add break point background.js:
function foo() { return 5; } foo(); //break point here then reload extension in chrome://extensions. nothing happens. breakpoint not triggered. background script running @ all?
simple answer... struggled while too...
once click background.html (or background.js), open in separate debugger window. @ point, reload hitting f5 or ctrl-f5 key(s) debugger window (while in focus).
note: may receive errors recreating objects exist (since created when first clicked on page(or script)
