I am trying to make a simple extension, where the user can do a dictionary search by hitting a shortcut. It will open a new tab with the dictionary search of the word selected by the user. However, when I try to use "window.getSelection()", it returns an empty string. I am using the Chrome browser, latest version.
This is the background2.js file.
chrome.commands.onCommand.addListener(function(command)
console.log('onCommand event received for message: ', command);
chrome.tabs.create(
url: "https://jisho.org/search/" + encodeURIComponent(window.getSelection().toString()),
active: true
);
);
This is the manifest.json file.
"manifest_version": 2,
"name": "Jisho Dictionary Search",
"permissions": [ "contextMenus" , "tabs" ],
"version": "1.2",
"background":
"scripts": [ "background.js", "background2.js" ]
,
"description": "Adds a shortcut to do a Jisho search automatically",
"browser_action":
"default_popup" : "browser_action.html"
,
"commands":
"toggle_feature":
"suggested_key": "default": "Ctrl+X" ,
"description" : "Opens new tab with word search on Jisho"
,
"_execute_browser_action":
"suggested_key":
"default": "Ctrl+Shift+X"
Can someone help me understand why it is returning an empty string and how could I make it return the word the user selected?

The background script runs in a separate hidden background page. You need to run a content script to access the web page's selection and pass it to the background script via messaging or executeScript's callback as shown in other answers and examples.
