How to execute javascript code from button in popup.html

[Kwstas Na]

Hello.

I have already made the popup.html design

and it loads perfect.

I have added one button on the popup.html and i would like you to give me any example of what should i do

so this button when is pushed to execute one javascript code.

I have already tried " <script></script> tags and write inside my code but its not working.

Any other ideas?
