Chrome-extension: Append functions to right click menu

Question

How would I append functions to the right click menu in the browser? E.g something appended to the right click menu which does function dosomething() which is located in my extension.

Answer 1

I made simple extenstion using the contextMenu API - link
Hope this works well as an example.

manifest.json -

{   "manifest_version": 2,   ...   ...   "permissions": [       "contextMenus",        "tabs"],   ...   ...   "background": {     "page": "background.html",     "scripts": ["main.js"]   } } 

main.js -

 searchUrbanDict = function(word){     var query = word.selectionText;     chrome.tabs.create({url: "http://www.urbandictionary.com/define.php?term=" + query});  };  chrome.contextMenus.create({  title: "Search in UrbanDictionary",  contexts:["selection"],  // ContextType  onclick: searchUrbanDict // A callback function });
