Merging multiple Google calendar feeds into one JSON object in javascript - javascript

I am trying to bring in the JSON feeds from multiple Google calendars so that I can sort the upcoming events and display the next X number in an "Upcoming Events" list.
I have this working with Yahoo! pipes but I want to get away from using a 3rd party to aggregate. I think I am close, but I cannot get the JSON objects created correctly. I am getting the data into the array but not in JSON format, so I can't manipulate it.
I have tried var myJsonString = JSON.stringify(JSONData); using https://github.com/douglascrockford/JSON-js but that just threw errors. I suspect because my variable is in the wrong starting format. I have tried just calling the feed like: $.getJSON(url); and creating a function concant1() to do the JSONData=JSONData.concat(data);, but it doesn't fire and I think it would produce the same end result anyway. I have also tried several other methods of getting the end result I want with varying degrees of doom. Here is the closest I have come so far:
var JSONData = new Array();
var urllist = ["https://www.google.com/calendar/feeds/dg61asqgqg4pust2l20obgdl64%40group.calendar.google.com/public/full?orderby=starttime&max-results=3&sortorder=ascending&futureevents=true&ctz=America/New_York&singleevents=true&alt=json&callback=concant1","https://www.google.com/calendar/feeds/5oc3kvp7lnu5rd4krg2skcu2ng%40group.calendar.google.com/public/full?orderby=starttime&max-results=3&sortorder=ascending&futureevents=true&ctz=America/New_York&singleevents=true&alt=json&callback=concant1","http://www.google.com/calendar/feeds/rine4umu96kl6t46v4fartnho8%40group.calendar.google.com/public/full?orderby=starttime&max-results=3&sortorder=ascending&futureevents=true&ctz=America/New_York&singleevents=true&alt=json&callback=concant1"];
urllist.forEach(function addFeed(url){
alert("The URL being used: "+ url);
if (void 0 != JSONData){JSONData=JSONData.concat($.getJSON(url));}
else{JSONData = $.getJSON(url);}
alert("The count from concantonated JSONData: "+JSONData.length);
});
document.write("The final count from JSONData: "+JSONData.length+"<p>");
console.log(JSONData)
UPDATE:
Now with full working source!! :) If anyone would like to make suggestions on how to improve the code's efficiency it would be gratefully accepted. I hope others find this useful.:

All right, here's the gist of what needs to change.
Updated fiddle: http://jsfiddle.net/ynuQ5/2/
Don't concat on the return value of $.getJSON. As I mentioned above, that gets you the XMLHttpRequest object, which is a lot more than the data you're interested in. Critically, however, at that point the request hasn't been made and the data isn't available yet.
Instead, handle it in callback for the AJAX request. I updated your URL list to use &callback=?, initialize the JSONData var to look more like the structure in your 2nd screenshot and then changed the javascript for the AJAX requests to this:
var JSONData = { count: 0,
value : {
description: "Calendars from the Unitarian Universalist Association (UUA.org)",
generator: "StackOverflow communal coding",
items: []
}};
// url list declaration goes here
urllist.forEach(function addFeed(url){
$.getJSON(url, function(result) {
if(!result.feed.entry) {
console.log("No entries from " + url);
return;
}
JSONData.count += result.feed.entry.length;
JSONData.value.items = JSONData.value.items.concat(result.feed.entry);
console.log(JSONData);
});
});
Right away you'll notice there are still some discrepancies between the raw data you get back from google and the data provided by the Yahoo pipe transform. Noticeably, a lot of their provided values have been transformed from objects to texts. For example, google gives us this:
id: Object
$t: "http://www.google.com/calendar/feeds/5oc3kvp7lnu5rd4krg2skcu2ng%40group.calendar.google.com/public/full/bbidp5qb4vh5vk9apok1cpnino_20130119"
link: Array[2]
0: Object
href: "https://www.google.com/calendar/event?eid=YmJpZHA1cWI0dmg1dms5YXBvazFjcG5pbm9fMjAxMzAxMTkgNW9jM2t2cDdsbnU1cmQ0a3JnMnNrY3UybmdAZw"
rel: "alternate"
title: "alternate"
type: "text/html"
1: Object
length: 2
published: Object
$t: "2012-11-13T15:59:31.000-05:00"
title: Object
$t: "30 Days of Love"
type: "text"
updated: Object
$t: "2012-11-13T15:59:31.000-05:00"
Where as your yahoo transform returns data more like this:
id: "http://www.google.com/calendar/feeds/5oc3kvp7lnu5rd4krg2skcu2ng%40group.calendar.google.com/public/full/bbidp5qb4vh5vk9apok1cpnino_20130119"
link: "href: "https://www.google.com/calendar/event?eid=YmJpZHA1cWI0dmg1dms5YXBvazFjcG5pbm9fMjAxMzAxMTkgNW9jM2t2cDdsbnU1cmQ0a3JnMnNrY3UybmdAZw"
published: "2012-11-13T15:59:31.000-05:00"
title: "30 Days of Love"
updated: "2012-11-13T15:59:31.000-05:00"
You can transform the data more when you receive it. Or you can modify your display code to use the more convoluted, raw values.
Let me know if I can clear anything up in my code or response.
Edit: Updated fiddle showing how to access author (aka feed name, apparently), start time and title: http://jsfiddle.net/ynuQ5/8/
Let me know if there's more specific stuff you want out of it :-)

First off, let me say that I am not a developer, nor do I really code beyond basic HTML. So I appreciate your patience. :)
I'm working with a script that is for AdWords, but I believe it's more or less written in Javascript. (I've included the script below.)
Basically, I'm receiving the error message 'Parsing Error: Please check your selector. (line XX)' when I preview the script.
I've searched all around for hours and have yet to find a solution.
I think it may be that a query being returned contains either a single or double quote, and may be messing up the code? Though I can't actually prove that.
Also, yes, I was sure to update lines 17-21 with the correct details.
Any help would be much appreciated!
Thanks!

The area between SELECT and FROM is the selector. You're not selecting any fields with that query. That's happening because the headerNames array is empty. Verify the value of REPORT_SHEET_NAME

I'm having trouble producing a script to match an object's value in object array based on an object's value in a separate array, and retrieve a separate value from that object.
I have used standard for-loops and the current iteration in jQuery each.
I have also tried setting the if statement to look for the two values as ==, but it always produces non matches (or -1).
Can anyone steer me in the right direction here?
transfers = [
{Package: "1", Origin_Facility = "a"},
{Package: "2", Origin_Facility = "b"}
];
storeData = [
{fromPackage: "1,6,26"}
]
var storeDataEach = function( sx, sxv ) {
var transfersEach = function( sy, syv ) {
if(storeData[sx].fromPackage.indexOf(transfers[sy].Package) > -1){
var facilityStore = transfers[sx].Origin_Facility;
storeData[sx].origin = facilityStore + " + " + transfers[sy].Package + ' + ' + storeData[sx].fromPackage;
return false;
} else {storeData[sx].origin = 'error' + transfers[sy].Package + " + " + storeData[sx].fromPackage;return false;}
};
jQuery.each(transfers, transfersEach);
}
jQuery.each(storeData, storeDataEach);

The main problem is you are returning false from the $.each loop which will stop the iteration
A crude fix is to remove the return from else block
var storeDataEach = function(sx, sxv) {
var transfersEach = function(sy, syv) {
if (storeData[sx].fromPackage.indexOf(transfers[sy].Package) > -1) {
var facilityStore = transfers[sx].Origin_Facility;
storeData[sx].origin = facilityStore + " + " + transfers[sy].Package + ' + ' + storeData[sx].fromPackage;
return false;
} else {
storeData[sx].origin = 'error' + transfers[sy].Package + " + " + storeData[sx].fromPackage;
}
};
jQuery.each(transfers, transfersEach);
}
But this still have problems with the data structure, in your example you have 26 in the fromPackage, now if you have a package value of 2 that also will return a positive result

I am proxying the function console.log to add some information to my logs and I am as well checking whether the information being logged is an object. I do this to avoid getting a log entry of the sort

Code works fine when passing arguments that are not objects. For example, the command
console.log("hello","world");
prints
2016-12-17 (22:23:53) > hello
2016-12-17 (22:23:53) > world
But if I pass an object as well, the code will fail to insert a new line after the object. For example, the command
console.log("hello",{world:true,hello:{amount:1,text:"hello"}},"world");
prints
2016-12-17 (22:27:32) > hello
2016-12-17 (22:27:32) > { world: true, hello: { amount: 1, text: hello } } 2016-12-17 (22:27:33) > world
(note the missing line break after displaying the object).
Code
JQuery 3.1.1
main.js:
(function (proxied) {
function displayArg(argument){
var result= "";
if(typeof argument == "object") {
result += "{ ";
for (i in argument) {
result += i + ": ";
result += (displayArg(argument[i]));
result += ", "
}
result = result.substring(0,result.length - 2);
result += " }";
return result;
} else {
return argument;
}
}
console.log = function () {
var result = [];
for (i in arguments) {
var d = new Date();
result[i] = d.getFullYear() + "-" + (d.getMonth() + 1) + "-" + d.getDate() +
" (" + d.getHours() + ":" + d.getMinutes() + ":" + d.getSeconds() + ") > ";
result[i] += displayArg(arguments[i]);
result[i] += "\n";
}
return proxied.apply(this, result);
}
})(console.log);

I'm not fully understanding objective but what about something along the lines of the following oversimplified override:
var oldLog = console.log;
console.log= function(){
var d= new Date(),
dateString = // process string
.....
for(var i = 0; i<arguments.length; i++){
oldLog(dateString, arguments[i]);
}
}

TL;DR change the iterator variables so they don't share name, or add a "var" to the loop definition to make sure they don't escape your desired scope.
It turns out that the for loops from (my own) console.log and displayArg were "sharing" the value of the iterator i. This is because by not declaring the iterator variable, the scope was broader than what I needed. To clarify, look at this example:
console.log({isThis:"real life"},"hello","world")
The code from console.log will add a date to the beginning of result[0] and then call displayArg(arguments[0]), arguments[0] being {isThis:"real life"}. That function, will iterate over the objects properties, thus i will be assigned the value isThis. After the function returns, the value of i will not go back to 0. Instead, i will be isThis and as a consequence, the line
result[i] += "\n";
translates to
result[isThis] += "\n"
instead of
result[0] += "\n"
Probably the most sensible solution was to add a var in the for declaration of the iterators. The following code works as expected:
(function (proxied) {
function displayArg(argument){
var result= "";
if(typeof argument == "object") {
result += "{ ";
for (var i in argument) {
result += i + ": ";
result += (displayArg(argument[i]));
result += ", "
}
result = result.substring(0,result.length - 2);
result += " }";
return result;
} else {
return argument;
}
}
console.log = function () {
var result = [];
for (var i in arguments) {
var d = new Date();
result[i] = d.getFullYear() + "-" + (d.getMonth() + 1) + "-" + d.getDate() +
" (" + d.getHours() + ":" + d.getMinutes() + ":" + d.getSeconds() + ") > ";
result[i] += displayArg(arguments[i]);
result[i] += "\n";
}
return proxied.apply(this, result);
}
})(console.log);

Here is a demo of the current code: http://mobilocloud.com/schedule/
I have one js object that contains multiple arrays, each array has two time hashes (one start time and one end time / I've got them using getTime()). I want to compare all of the arrays contained in the object to check for all of the intersections between time ranges. I've got the script working but it only compares two arrays at a time (in the end I get groups of two overlapped events). I want to get groups of all overlapped events, not only by two.
Here is the actual code:
function _DetectOverlapedEvents(column) {
events;
groups;
sgroups;
todeoverlap[column] = new Array();
groups[column] = new Array();
sgroups[column] = new Array();
var $curid=0;
var $curevent= new Array();
if(events[column].length > 1){
$(events[column]).each(function(key, $secondevent) {
//alert("Comparing : " + $curevent["name"] + " and " + $secondevent["name"] + "\n" + $curevent["starthash"] + "<" +$secondevent["endhash"] + " = " + ($curevent["starthash"] < $secondevent["endhash"]) + "\n&&\n" + $curevent["endhash"] + ">" + $secondevent["starthash"] + " = " + ($curevent["endhash"] > $secondevent["starthash"]));
if($curevent.length<2) {
$curevent=$secondevent;
} else if(($curevent["starthash"] < $secondevent["endhash"]) && ($curevent["endhash"] > $secondevent["starthash"])) {
//alert("added " + $curevent["name"] + " and " + $secondevent["name"]);
toextend = {left: $curevent, right: $secondevent};
groups[column].push(toextend);
sgroups[column].push($curevent, $secondevent);
//console.log("groups: " + JSON.stringify(groups[column]));
$curid++;
}
$curevent = $secondevent;
});
}
//console.log(JSON.stringify(groups));
}

I am able to display my tweets in my website using the JavaScript below.
window.onload = function() {
var siteName = 'xyz';
$.getJSON(
'http://search.twitter.com/search.json?callback=?&rpp=20&q=from:' + siteName,
function(data) {
$.each(data, function(i, tweets) {
for (var num = 0, len = tweets.length; num < len; num++) {
if (tweets[num].text !== undefined) {
$('ul#tweets').append('<li><b>' + tweets[num].created_at.substring(0, 16) +
':</b> ' + tweets[num].text + '</li>');
}
}
});
}
);
};
This displays the tweets in US time. Is it possible to show the tweets in NZ time.

I found an easy solution to my problem. Just creating a new Date object (var tim = new Date(tweets[num].created_at)) did the trick. Here is the code which give shows date and time of tweets in my timezone.
window.onload = function() {
var siteName = 'xyz';
$.getJSON(
'http://search.twitter.com/search.json?callback=?&rpp=20&q=from:' + siteName,
function(data) {
$.each(data, function(i, tweets) {
for (var num = 0, len = tweets.length; num < len; num++) {
if (tweets[num].text !== undefined) {
var tim = new Date(tweets[num].created_at);
$('ul#tweets').append('<li><b>' + tim.toString().substring(0, 24) + ':</b> ' + tweets[num].text + '</li>');
}
}
});
}
);
};
I think, the var tim = new Data(tweets[num].created_at) constructor is taking the date from tweets[num].created_at and converting it to local timezone (my machine time) and constructing a new object tim. So the new object tim has local time.
Can anyone please point me to the documentation of the Date(dateString) constructor.

Yes. You can change the timezone.
The following js code snippet was found from Twitter's web.
function changetimezone(time_value, tz){
if(!tz){
tz = 0;
}
var values = time_value.split(" ");
time_value = values[1] + " " + values[2] + ", " + values[5] + " " + values[3];
var t = parseInt(Date.parse(time_value))/1000;
return t + tz * 60;
}
So simply parse changetimezone with created_at and your relative timezone.
e.g. changetimezone(tweets[num].created_at,12);
+1200hrs is New Zealand's timezone.
As for what twitter returns, it's actually not US time. It's GMT+0 (London time). So you can safely put 12hrs instead of 20.
