From popup.html, how can I run a javascript function by button onclick?

I'm trying to build an extension for Chrome, but I'm a newbie and I'm having trouble understanding the Docs provided by Google. I want the extension to have a popup that shows a few buttons, and when a button is clicked, I want to run a script.

This is my setup:

popup.html

<button id="test1" onclick="getSite();">button 1</button>
<button id="test2" onclick="getSite();">button 2</button>

content_script.js

function getSite(){alert('getSite works!');}

I'm having trouble understanding how to use the chrome javascript api, as I see others saying use chrome.tabs.executeScript, but I can't figure out where that line goes. Can anyone help me? I'll give you a cookie! or just an upvote.. or maybe both?

You haven't mentioned on which page you want your scripts to run onclick, in Popup.html page or the page on which user is currently working on the browser. If it is just the popup.html page in which you want to execute your script, include them in popup.html page itself.

If however you want to execute them on the user's browser page, You will have to pass a message to your background page, which in turn will execute chrome.tabs.executeScript with current tab's id and {file: 'yourjsfile.js'} as arguments.

I think you are having this problem because of restrictions imposed by the Google Content Security Policy. It mentions that iniline javascript like the one that you have mentioned in you code will not be executed. Try removing the onclick="getSite()" from your HTML markup to content_script.js. Use addEventListener function to attach the event to the button.
