在Google文档中捕获文本选择 [英] Capture text selection in Google Docs
问题描述
我正在编写一个Chrome扩展程序,用于捕获用户文本选择并将选定文本发送给Google搜索。
{
manifest_version:2,
名称:选择扩展,
description:搜索您选择的文本,
version:1.0,
permissions:[
tabs,
http:// * / *,
https:// * / *
,
background:{
scripts:[
background.js
],
持久性:false
},
browser_action:{
default_icon:icon.png,
default_title:标记!!
},
content_scripts:[
{
matches:[< all_urls>],
js:[content_script.js ]
}
]
content_script.js
chrome.extension.onMessage.addListener(function(request,sender,sendResponse){
if(request。方法==getSelection){
sendResponse({data:window.getSelection()。toString()});
} else {
sendResponse({});
}
});
background.js
函数initBackground(){
chrome.browserAction.onClicked.addListener(function(tab){
chrome.tabs.sendMessage(tab .id,{method:getSelection},function(response){
sendServiceRequest(response.data);
});
});
}
函数sendServiceRequest(selectedText){
var serviceCall ='http://www.google.com/search?q='+ selectedText;
chrome.tabs.create({url:serviceCall});
}
initBackground();
此代码适用于网页中的选择(例如Gmail,Facebook,新闻)。
我也希望能够通过PDF和Google Docs(在浏览器中查看)获得选择内容。
在这些情况下: window.getSelection
返回一个空字符串...
有人知道如何Google Docs文档并不真正遵循如何从扩展访问文本的正常方式。
我出于这个原因创建了一个工具来处理Google文档,可以在这里找到 a>
这应该使您能够:
// contentScript .js
var googleDocument = googleDocsUtil.getGoogleDocument();
console.log(所选文字为:+ googleDocument.selectedText);
I'm writing a Chrome extension that captures the user text selection and sends the selected text to Google search.
manifest.json
{
"manifest_version": 2,
"name": "Selection Extension",
"description": "Search your selected text",
"version": "1.0",
"permissions": [
"tabs",
"http://*/*",
"https://*/*"
],
"background": {
"scripts": [
"background.js"
],
"persistent": false
},
"browser_action": {
"default_icon": "icon.png",
"default_title": "Mark it!!"
},
"content_scripts": [
{
"matches": ["<all_urls>"],
"js": ["content_script.js"]
}
]
content_script.js
chrome.extension.onMessage.addListener(function(request, sender, sendResponse) {
if (request.method == "getSelection") {
sendResponse({data: window.getSelection().toString()});
} else {
sendResponse({});
}
});
background.js
function initBackground() {
chrome.browserAction.onClicked.addListener(function(tab) {
chrome.tabs.sendMessage(tab.id, {method: "getSelection"}, function(response){
sendServiceRequest(response.data);
});
});
}
function sendServiceRequest(selectedText) {
var serviceCall = 'http://www.google.com/search?q=' + selectedText;
chrome.tabs.create({url: serviceCall});
}
initBackground();
This code works for selection in webpages (such as Gmail, Facebook, news.)
I also want to be able to get the selection in PDF, and Google Docs (viewed in the browser).
In these cases: window.getSelection
returns an empty string...
Someone knows how to do it?
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);
