Menu
Goal
I am trying to use this boilerplate code to look up using a dictionary API online to find the selected word and return the definition.
Problem
I have tested the actual jQuery ajax call separately and it works well. Also, I can get the selected word on the page. However, for some reason I am having issues actually calling the ajax function within my boilerplate code in Sample.js
Advice is needed.
background.html
<html>
<script src="jquery.js"/>
<script src="sample.js"/>
<body>

You have to add permission for the url which you're calling in the ajax function to your manifest:
"permissions": [
"contextMenus",
"http://api.wordnik.com/*"
],
Don't forget to include jquery:
"background": { "scripts": ["jquery.js", "sample.js"], "pages": ["background.html"] }
and you don't need <script src="jquery.js"/> in your file
The link of website should have /* at the end of it.
