I\'m writing a Chrome extension that captures the user text selection and sends the selected text to Google search.
manifest.json
{
Google Docs document does not really follow the normal ways of how a to access text on from a Extension. I have for this reason created a tool to work with Google Docs, which can be found here
This should enable you to:
//contentScript.js
var googleDocument = googleDocsUtil.getGoogleDocument();
console.log("The selected text is: " + googleDocument.selectedText);
