recognize multple lines on info.selectionText from Context Menu - google-chrome-extension

My extension adds a context menu whenever a user selects some text on the page.
Then, using info.selectionText, I use the selected text on a function executed whenever the user selects one of the items from my context menu. (from http://code.google.com/chrome/extensions/contextMenus.html)
So far, all works ok.
Now, I got this cool request from one of the extension users, to execute that same function once per line of the selected text.
A user would select, for example, 3 lines of text, and my function would be called 3 times, once per line, with the corresponding line of text.
I haven't been able to split the info.selectionText so far, in order to recognize each line...
info.selectionText returns a single line of text, and could not find a way to split it.
Anyone knows if there's a way to do so? is there any "hidden" character to use for the split?
Thanks in advance... in case you're interested, here's the link to the extension

Ok, as OnClickData's selectionText is only ever going to be text you'll never be able to do it using this approach.
What I would do then is inject a content script into each page and use something similar to the below example (as inspired by reading this SO post - get selected text's html in div)
You could still use the context menu OnClickData hook like you do now but when you receive it instead of reading selectionText you use the event notification to then trigger your context script to read the selection using x.Selector.getSelected() instead. That should give you what you want. The text stays selected in your extension after using the context menu so you should have no problem reading the selected text.
if (!window.x) {
x = {};
}
// https://stackoverflow.com/questions/5669448/get-selected-texts-html-in-div
x.Selector = {};
x.Selector.getSelected = function() {
var html = "";
if (typeof window.getSelection != "undefined") {
var sel = window.getSelection();
if (sel.rangeCount) {
var container = document.createElement("div");
for (var i = 0, len = sel.rangeCount; i < len; ++i) {
container.appendChild(sel.getRangeAt(i).cloneContents());
}
html = container.innerHTML;
}
} else if (typeof document.selection != "undefined") {
if (document.selection.type == "Text") {
html = document.selection.createRange().htmlText;
}
}
return html;
}
$(document).ready(function() {
$(document).bind("mouseup", function() {
var mytext = x.Selector.getSelected();
alert(mytext);
console.log(mytext);
});
});​

How to make a text field link be opened in a new tab, in Velo?

In Wix, I have a text field in a repeater that is used for navigating to other dynamic pages. The link works, but there are two problems with that. First, I have to click two times, not double click, for functioning the link. Second, I want to make the text field act as a button link, I mean be able to right click on that and choose 'open in new tab'. How can I fix these problems in my code?
Here is the code
// Navigating to related dynaic page
import wixLocation from 'wix-location';
export function ndText_click(event) {
$w("#repeater1").onItemReady(($item, itemData, index) => {
$item("#nText").onClick((event) => {
let postTypeValue = itemData.pType
wixData.query("Collection1").eq("_id", itemData._id)
.find()
.then(results => {
let item = results.items[0];
let pIDValue = item.postId;
if (postTypeValue == "R") {
wixLocation.to('/re/' + postIDValue);
} else if (postTypeValue == "L") {
wixLocation.to('/lo/' + postIDValue);
}
})
});
})
}
I suggest trying to use a button instead of the text element. You can usually style the button so it looks the same as the text element you already have. Then instead of setting the onClick, try setting the button's link and target properties.

Check if a message has a label using Google Script

At work we have a google script code that is run every 4 hours and check everyone's #folders for unread mail. If unread mail is found it is moved to INBOX and tagged with ##UNREAD.
What i need is a way for the script to check if it already has the ##UNREAD tag and in that case not move to inbox.
This is the code
function process_unread() {
//Define user label
var label = GmailApp.getUserLabelByName("#Josh");
//Define unread label
var unreadlabel = GmailApp.getUserLabelByName("##UNREAD");
if (label) {
var threads = label.getThreads();
for (var i = 0; i < threads.length; i++) {
var thread = threads[i];
if (thread.isUnread()) {
//Remove label
thread.addLabel(unreadlabel);
thread.moveToInbox();
}
}
}
}
How can i only move emails if they do not have the ##UNREAD label?
Here is my attempt:
function process_unread() {
//Define user label
var label = GmailApp.getUserLabelByName("#Josh");
//Define unread label
var unreadlabel = GmailApp.getUserLabelByName("##UNREAD");
if (label) {
var threads = label.getThreads();
for (var i = 0; i < threads.length; i++) {
var thread = threads[i];
var labels = thread.getLabels();
var doesThisThreadHaveTheLabel = false;
for (var i = 0; i < labels.length; i++) {
var thisParticularLabel = labels[i].getName();
Logger.log(labels[i].getName());
if (thisParticularLabel === "##UNREAD") {
var doesThisThreadHaveTheLabel = true;
};
}
if (thread.isUnread() && doesThisThreadHaveTheLabel === false) {
//Remove label
thread.addLabel(unreadlabel);
thread.moveToInbox();
}
}
}
}
Before you move the thread to the inbox, you want to make sure it does NOT have the label. So add another condition to the If check.
if (thread.isUnread() && doesThisThreadHaveTheLabel === false) {
I created a variable: doesThisThreadHaveTheLabel that will either have a true or false value. It's default gets set to false before every for loop.
var doesThisThreadHaveTheLabel = false;
for (var i = 0; i < labels.length; i++) {
You can debug the code to check it:
In the above picture, you see an icon of a bug in the menu. Before you click that, first click the drop down menu just to the right of the bug, and choose the name of the function to run. Also, add a breakpoint to the code. In that picture you'll see a red dot in the line numbers in the code editor. That's where the code will stop.
I added the label #josh to one of the emails in my account, so the variable label has an object in it. But, I don't have any emails with a label ##UNREAD , so you'll notice that in the list of variables, the variable unreadlabel has a value of null.
In that picture, the code is suspended on the line, 269. I can step in to the next line of code by clicking the step in icon. Hover over the icon to get a context help to pop up.
I stepped line by line further, and retrieved the label that was put into the variable "ThisParticularLabel". You can see in the window, that it has a value of #Josh.
I stepped through that code, and it ended after the main for loop had run once. I also ran that code by itself without debugging it, and it ran in:
Execution succeeded [0.246 seconds total runtime]
You need to debug your code, and see what it is doing on every line, and know what every single variable has for a value, and how the conditional statements are working.
Script will not finish with two for loops both using variable i as i will be set to 0 continually by the inner for loop and will not increment. Switch inner loop to j variable and script will finish.

Multiple Tab Chrome Extension Issue

I've created a basic extension that searches Google if the URL/HTML content fulfill certain requirements. It works for the most part, but fails miserably when there are multiple instances of the extension. For example, if I load tab A and then tab B, but click on the page action for tab A, I will be directed to a search of tab B's content.
I don't know how to silo the script to each tab, so that clicking tab A's page action will always result in a search for tab A stuff. How can that be done? I'd appreciate your suggestions!
background.js
title = "";
luckySearchURL = "http://www.google.com/search?btnI=I%27m+Feeling+Lucky&ie=UTF-8&oe=UTF-8&q=";
chrome.runtime.onMessage.addListener(
function(request, sender, sendResponse) {
if (request.title != "") {
title = request.title;
sendResponse({confirm: "WE GOT IT."});
}
});
chrome.tabs.onUpdated.addListener(function(tabId, change, tab) {
if (change.status === "complete" && title !== "") {
chrome.pageAction.show(tabId);
}
});
chrome.pageAction.onClicked.addListener(function(tab) {
chrome.tabs.create({url: luckySearchURL + title})
})
contentscript.js
function getSearchContent() {
url = document.URL;
if (url.indexOf("example.com/") > -1)
return "example";
}
if (window === top) {
content = getSearchContent();
if (content !== null) {
chrome.runtime.sendMessage({title: content}, function(response) {
console.log(response.confirm); })
};
}
You could do something like store the title with its associated tabId, that way when you click on the pageAction it uses the correct title. The changes would be just these:
background.js
title= [];
[...]
chrome.runtime.onMessage.addListener(function(request,sender,sendResponse){
if (request.title != "") {
title.push({tabId:sender.tab.id, title:request.title});
sendResponse({confirm: "WE GOT IT."});
}
});
[...]
chrome.pageAction.onClicked.addListener(function(tab) {
title.forEach(function(v,i,a){
if(v.tabId == tab.id){
chrome.tabs.create({url: luckySearchURL + v.title});
// Here I am going to remove it from the array because otherwise the
// array would grow without bounds, but it would be better to remove
// it when the tab is closed so that you can use the pageAction more
// than once.
a.splice(i,1);
}
});
});
You're facing this issue because of window === top. So your title variable gets its value from the last opened tab. So if B is opened after A, title gets its value from B. Try this: Detect Tab Id which called the script, fetch the url of that tab, which then becomes your title variable. As below:
chrome.pageAction.onClicked.addListener(function(tab) {
chrome.tabs.query({active:true},function(tabs){
//this function gets tabs details of the active tab, the tab that clicked the pageAction
var urltab = tabs[0].url;
//get the url of the tab that called this script - in your case, tab A or B.
chrome.tabs.create({url: urltab + title});
});
});

When I close a window and then open a different one, the selected tab is recreated by Chrome

I am writing a Chrome extension that saves/restores your browsers window state - So, I save the state of a given window:
var properties = [ "top",
"left",
"width",
"height",
"incognito",
"focused",
"type"
];
var json = {};
var cache = chrome_window_object;
// copy only the keys we care about:
_.each(properties,function(key,value) {
json[key] = cache[key];
});
// then copy the URLs of the tabs, if they exist:
if(cache.tabs) {
json.url = [];
_.each(cache.tabs,function(tab) {
json.url.push(tab.url);
});
}
return json;
At some point in the future, I remove all windows:
closeAllWindows: function(done_callback) {
function got_all(windows) {
var index = 0;
// use a closure to only close one window at a time:
function close_next() {
if(windows.length <= index) return;
var window = windows[index++];
chrome.windows.remove(window,close_next);
}
// start closing windows:
close_next();
}
chrome.windows.getAll(got_all);
}
and then I restore the window using:
chrome.windows.create(json_from_before);
The window that is created has an extra tab in it, whatever was in the window that I just closed... I am completely floored, and I assume the problem is something that I am doing in the code that I haven't posted (it's a big extension). I've spent a few hours checking code line by line and making sure I'm not explicitly asking for this tab to be created. So - has anybody seen anything like this before?

Search box for mobile websites

After the search box is selected, it should expand in all directions to take up the remaining top row of the page in mobile device.I want to use HTML5,CSS3 and simple Javascript(no libraries).
How to implement it?
I got the way.Used javascript to move the search box up.
I passed the textbox as obj in the function below..It works!!!
function findPos(obj) {
var curtop = 0;
if (obj.offsetParent) {
do {
curtop += obj.offsetTop;
} while (obj = obj.offsetParent);
curtop=curtop-5;
return [curtop];
}
}
