Chrome Bookmarks API - - google-chrome-extension

I'm attempting to create a simple example that would just alert the first 5 bookmark titles.
I took Google's example code and stripped out the search query to see if I could create a basic way to cycle through all Nodes. The following test code fails my alert test and I do not know why.
function dumpBookmarks() {
var bookmarkTreeNodes = chrome.bookmarks.getTree(
function(bookmarkTreeNodes) {
(dumpTreeNodes(bookmarkTreeNodes));
});
}
function dumpTreeNodes(bookmarkNodes) {
var i;
for (i = 0; i < 5; i++) {
(dumpNode(bookmarkNodes[i]));
}
}
function dumpNode(bookmarkNode) {
alert(bookmarkNode.title);
};

Just dump your bookmarkTreeNodes into the console and you will see right away what is the problem:
var bookmarkTreeNodes = chrome.bookmarks.getTree(
function(bookmarkTreeNodes) {
console.log(bookmarkTreeNodes);
});
}
(to access the console go to chrome://extensions/ and click on background.html link)
As you would see a returned tree contains one root element with empty title. You would need to traverse its children to get to the actual bookmarks.
Simple bookmark traversal (just goes through all nodes):
function traverseBookmarks(bookmarkTreeNodes) {
for(var i=0;i<bookmarkTreeNodes.length;i++) {
console.log(bookmarkTreeNodes[i].title, bookmarkTreeNodes[i].url ? bookmarkTreeNodes[i].url : "[Folder]");
if(bookmarkTreeNodes[i].children) {
traverseBookmarks(bookmarkTreeNodes[i].children);
}
}
}

Orchard CMS Contrib.Review module

I am beginner in Orchard CMS and i need add voting functionality to content. I have installed Contib.Vote and Contrib.Review modules. After that i have added Review part to page content type. Also, i have executed recipe. At the first look everything is fine, but link for review refer to the same page with # symbol and nothing is happenning by clicking on it. It seems like module does not work or work incorrectly. Please help with my problem.
UPD.
Hi devqon and thanx for your help. Your answer was really useful for me. According to your advice i was looking around javascript inside Review Part view file (Parts_Reviews.cshtml). Just for a test i changed its source code a little bit.
#using (Script.Foot())
{
<script type="text/javascript">
//<![CDATA[
(function () {
var numberOfReviewsToShowByDefault = 5;
var $showAllReviewsLink = $('#showAllReviewsLink');
var $deleteReviewConfirmationDialogDiv = $('#deleteReviewConfirmationDialogDiv');
$deleteReviewConfirmationDialogDiv.dialog({ autoOpen: false, modal: true, resizable: false });
$('#deleteReviewLink').click(function () {
$('#reviewId').val($(this).attr("data-review-id"));
ShowDeleteReviewDialog();
return false;
});
$('#showReviewFormLink').click(function () {
$('#createReviewLinkDiv').slideToggle('fast', function () { $('#reviewFormDiv').slideToggle('fast'); });
return false;
});
$('#cancelCreateReviewLink').click(function () {
$('#reviewFormDiv').slideToggle('fast', function() { $('#createReviewLinkDiv').slideToggle('fast'); });
return false;
});
$('#deleteReviewForm').submit(function () {
$('input[type=submit]', this).attr('disabled', 'disabled');
});
$('#cancelDeleteReviewButton').click(function () {
CloseConfirmationDialogDiv();
return false;
});
var rowCount = $('#reviewsList li').length;
if (rowCount > numberOfReviewsToShowByDefault) {
SetupToggle();
}
if (document.location.hash === '#Reviews') {
var topPx = $('#reviews-heading').position().top;
$('body,html').animate({ scrollTop: topPx }, 'slow');
}
if ($("#comment").length) {
var characterCountUpdater = new CharacterCountUpdater($("#comment"), $("#commentCharactersLeft"));
setInterval(function() { characterCountUpdater.UpdateCharacterCount(); }, 100);
$("#comment").keypress(function() { characterCountUpdater.UpdateCharacterCount(); });
if ($("#comment").val().length) {
$("#showReviewFormLink").trigger("click");
}
}
function CharacterCountUpdater(commentBox, charactersLeftBox)
{
this.commentBox = commentBox;
this.charactersLeftBox = charactersLeftBox;
this.maxLength = commentBox.attr("maxlength");
commentBox.removeAttr("maxlength");
return this;
}
Now form for review is displayed. The form looks good, submit button works, character counter works too. But i still can't apply my rating. Stars not react on clicking. That is why submit operation ends with error 'In order to submit a review, you must also submit a rating.'. Look like something inside Parts.Stars.NoAverage.cshtml does not work. Please, help me.
According to the project's site it is a known issue: broken from version 1.7.2.
When looking at the code of the Parts_Reviews.cshtml it says the following on lines 20-24:
string showReviewUri = "#";
if (!Request.IsAuthenticated)
{
showReviewUri = Url.Action("LogOn", "Account", new { area = "Orchard.Users", ReturnUrl = Context.Request.RawUrl });
}
and on line 29:
<div id="createReviewLinkDiv"><span id="createReviewLinkSpan">#noReviewsYetText<a id="showReviewFormLink" href="#showReviewUri">#reviewLinkText</a></span></div>
Therefore, it was intended to let the anchor be # when the request is authenticated (you are logged on). This means it probably will be handled in JavaScript, which can be seen on lines 105-112:
$('#showReviewFormLink').click(function () {
$('#createReviewLinkDiv').slideToggle('fast', function () { $('#reviewFormDiv').slideToggle('fast'); });
return false;
});
$('#cancelCreateReviewLink').click(function () {
$('#reviewFormDiv').slideToggle('fast', function() { $('#createReviewLinkDiv').slideToggle('fast'); });
return false;
});
This piece of code should let you see the form to write a review, so something is going wrong there presumably. When there's something wrong in this jQuery code it probably gives an error in the console, so check out the browser's console when you click the 'Be the first to write a review' link.
This should get you further, if you don't know what to do please provide the error and I will try to dig more. I haven't downloaded the module so I don't have live feed.
Console of Firefox tells: $(...).live is not a function. It refers to Contrib.Stars.js source code file. This function is not supported in jquery now and i replaced it by .on() function in all places api.jquery.com/on. Now module works fine.
Check out my comment at the site below to see how I was was able to get it working again on Orchard 1.8.1:
Orchard Reviews Project Site
You basically just need to change 3 different lines in the Contrib.Stars.js file but I would recommend copying the .js file along with the Review module's different views to a custom theme directory, in order to override everything and force the Reviews module to use your edited .js file:
On line 12 & 13:
Change this:
$(".stars-clear").live(
"click",
To this:
$("body").on(
"click", ".stars-clear",
On line 44 & 45:
Change this:
.live(
"mouseenter",
To this:
.mouseenter(
On line 48 & 49:
Change this:
.live(
"mouseleave",
To this:
.mouseleave(

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?

recognize multple lines on info.selectionText from Context Menu

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
https://chrome.google.com/webstore/detail/aagminaekdpcfimcbhknlgjmpnnnmooo
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);
});
});​

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];
}
}

How to snap a polyline to a road with walking travelmode in Google Maps?

II want an user to draw a route with polylines on GoogleMaps. I've found a way to snap a polyline ( example in the link, code in below ). The code works with the directions service to draw a polyline on a road, the only problem is this only works with G_TRAVELMODE_DRIVING but I want to use G_TRAVELMODE_WALKING and when you use WALKING you have to supply the map and a div in the constructor of the directions object. When I do that it automatically removes the last line and only displays the current line. I've tried several things like supplying the map as null, or leaving out the map in the constructor.. I've also tried to give a second map in the constructor, get the polylines from the directions service and display them on the right map. But nothing works! I'd appreciate it if someone could help me!
http://econym.org.uk/gmap/example_snappath.htm
if (GBrowserIsCompatible()) {
var map = new GMap2(document.getElementById("map"));
map.setCenter(new GLatLng(53.7877, -2.9832),13)
map.addControl(new GLargeMapControl());
map.addControl(new GMapTypeControl());
var dirn = new GDirections();
var firstpoint = true;
var gmarkers = [];
var gpolys = [];
var dist = 0;
GEvent.addListener(map, "click", function(overlay,point) {
// == When the user clicks on a the map, get directiobns from that point to itself ==
if (!overlay) {
if (firstpoint) {
dirn.loadFromWaypoints([point.toUrlValue(6),point.toUrlValue(6)],{getPolyline:true});
} else {
dirn.loadFromWaypoints([gmarkers[gmarkers.length-1].getPoint(),point.toUrlValue(6)],{getPolyline:true});
}
}
});
// == when the load event completes, plot the point on the street ==
GEvent.addListener(dirn,"load", function() {
// snap to last vertex in the polyline
var n = dirn.getPolyline().getVertexCount();
var p=dirn.getPolyline().getVertex(n-1);
var marker=new GMarker(p);
map.addOverlay(marker);
// store the details
gmarkers.push(marker);
if (!firstpoint) {
map.addOverlay(dirn.getPolyline());
gpolys.push(dirn.getPolyline());
dist += dirn.getPolyline().Distance();
document.getElementById("distance").innerHTML="Path length: "+(dist/1000).toFixed(2)+" km. "+(dist/1609.344).toFixed(2)+" miles.";
}
firstpoint = false;
});
GEvent.addListener(dirn,"error", function() {
GLog.write("Failed: "+dirn.getStatus().code);
});
}
else {
alert("Sorry, the Google Maps API is not compatible with this browser");
}
I know it's an old post, but since no answer came forward and I've recently been working on this sort of code (and got it working), try swapping the addListener with this.
GEvent.addListener(map, "click", function(overlay,point) {
// == When the user clicks on a the map, get directiobns from that point to itself ==
if (!overlay) {
if (firstpoint) {
dirn1.loadFromWaypoints([point.toUrlValue(6),point.toUrlValue(6)],{ getPolyline:true,travelMode:G_TRAVEL_MODE_WALKING});
} else {
dirn1.loadFromWaypoints([gmarkers[gmarkers.length-1].getPoint(),point.toUrlValue(6)],{ getPolyline:true,travelMode:G_TRAVEL_MODE_WALKING});
}
}
});
