removing cookies using javascript is not done immediatly

I am currently working with a javascript that is supposed to remove some unwanted cookies, but for some reason aren't they removed when told to?..
only after certain amount of times trying to remove them, they seem to be removed.. some sort of delayed effect?
here is the code:
const name = 'test_u';
const name1 = 'test_te_s';
function eraseCookie(name) {
document.cookie = name+'=; Max-Age=-99999999;';
}
function removeCookies(cookieA, cookieB) {
setInterval(function() {
if (document.cookie.includes(cookieA) || document.cookie.includes(cookieB))
{
eraseCookie(cookieA);
eraseCookie(cookieB);
var date = new Date();
var timestamp = date.getTime();
console.log(timestamp)
}
},10000);
}
removeCookies(name, name1);
example from console log output:
1555420706478
1555420716477
1555420726487
1555420736487
1555420746497
1555420756487
It runs 6 times before its removed? but why though?
why aren't they removed immediately?

Because you have setInterval which means that that code will be run after some time that you provide, and keep repeating it by that interval. So just remove that setInterval:
function removeCookies(cookieA, cookieB) {
if (document.cookie.includes(cookieA) || document.cookie.includes(cookieB)) {
eraseCookie(cookieA);
eraseCookie(cookieB);
var date = new Date();
var timestamp = date.getTime();
console.log(timestamp)
}
}
And if you want to keep repeating it try this one:
removeCookies(name, name1);
setInterval(() => {
removeCookies(name, name1);
}, 10000);
or
function removeCookies(cookieA, cookieB) {
if (document.cookie.includes(cookieA) || document.cookie.includes(cookieB)) {
eraseCookie(cookieA);
eraseCookie(cookieB);
var date = new Date();
var timestamp = date.getTime();
console.log(timestamp)
}
setInterval(() => {
removeCookies()
}, 10000);
}
removeCookies(name, name1);
so it will first call removeCookies, and then it will keep repeating.

How to delay 15 minutes? 5 minutes restriction

Here is a very simple program that I wrote:
function () {
var app = SpreadsheetApp ;
var tableur = app.getActiveSpreadsheet() ;
var feuille = tableur.getActiveSheet();
var now = new Date();
Utilities.sleep(900000)
feuille.getRange("A1000").setValue(now);
feuille.getRange("B1000:O1000").setValue("1000000");
feuille.getRange("P1000").setValue("Prudent");
feuille.getRange("Q1000").setValue("10");
feuille.getRange("R1000").setValue("10");
feuille.getRange("S1000").setValue("NON");
}
However, I want the code to wait 15 minutes before it continues. Google has a restriction of 5 minutes, which is why I read a lot about this issue but I couldn't find any solution. I actually used Utilities.sleep (900000) but it doesn't work.
I appeal to your kindness to explain to a beginner like me how to circumvent the restriction if ever this is possible! :)
function onEdit(e) {
var triggerTime = new Date();
var scriptProperties = PropertiesService.getScriptProperties();
scriptProperties.setProperty("lastTrigger", triggerTime);
}
function doSomething() {
var scriptProperties = PropertiesService.getScriptProperties();
var lastTrigger = new Date(scriptProperties.getProperty("lastTrigger"));
var lastTriggerUnix = lastTrigger.getTime() / 1000; // using unix time for a more straightforward time comparison
var nowUnix = (new Date()).getTime() / 1000;
var FIFTEEN_MINUTES = 15 * 60;
if ((nowUnix - lastTriggerUnix) >= FIFTEEN_MINUTES) {
scriptProperties.deleteProperty("lastTrigger");
var app = SpreadsheetApp ;
var tableur = app.getActiveSpreadsheet() ;
var feuille = tableur.getSheetByName("Réponses"); // getActiveSheet() can yield unexpected results
var app = SpreadsheetApp ;
var now = new Date()
feuille.getRange("A10").setValue(now);
feuille.getRange("B10:O10").setValue("1000000");
feuille.getRange("P10").setValue("Prudent");
feuille.getRange("Q10").setValue("10");
feuille.getRange("R10").setValue("10");
feuille.getRange("S10").setValue("NON");
}
}
Is there something I forgot?

Given the new information that you want the doSomething() script to run roughly 15 minutes after the spreadsheet was last edited, here's my modification, but using the same general principle.
Create an onEdit() simple trigger that saves the edit time to the Properties Service (this is done by simply including the onEdit function, which Google interprets automatically). Separately, create a manual trigger to run the doSomething() function every 5 minutes or so. When that function runs, it will check the last edit time and execute your desired actions if the difference between the last edit and now is greater than or equal to your desired length.
function onEdit(e) {
var triggerTime = new Date();
var scriptProperties = PropertiesService.getScriptProperties();
scriptProperties.setProperty("lastTrigger", triggerTime);
}
function doSomething() {
var scriptProperties = PropertiesService.getScriptProperties();
var lastTrigger = new Date(scriptProperties.getProperty("lastTrigger"));
var lastTriggerUnix = lastTrigger.getTime() / 1000; // using unix time for a more straightforward time comparison
var nowUnix = (new Date()).getTime() / 1000;
var FIFTEEN_MINUTES = 15 * 60;
if ((nowUnix - lastTriggerUnix) >= FIFTEEN_MINUTES) {
scriptProperties.deleteProperty("lastTrigger");
// Do what you need to do here
}
}
You should use the Properties Service to save now, then use a Trigger to run the script every 15 minutes. (The first time you run it, the timings might be slightly off.)
function doSomething() {
var app = SpreadsheetApp ;
var tableur = app.getActiveSpreadsheet() ;
var feuille = tableur.getSheetByName("Sheet2"); // getActiveSheet() can yield unexpected results
var scriptProperties = PropertiesService.getScriptProperties();
var storedNow = scriptProperties.getProperty("now") || new Date(); // Get the stored time. If it doesn't exist, create a new one.
var now = new Date(storedNow); // The value is stored as a String in the Properties Service, so convert to Date.
feuille.getRange("A10").setValue(now);
feuille.getRange("B10:O10").setValue("1000000");
feuille.getRange("P10").setValue("Prudent");
feuille.getRange("Q10").setValue("10");
feuille.getRange("R10").setValue("10");
feuille.getRange("S10").setValue("NON");
now = new Date(); // Create a new date to be used when the function runs again
scriptProperties.setProperty("now", now); // Save the new date
}
As noted in the trigger documentation, you can create the trigger from the Edit menu > Current project's triggers.
I tested this on a 5-minute interval and received the below outputs. As I manually ran the function the first time, its time value is not consistent with the subsequent iterations.

Nightwatch - wait for text of an element

I am new to Nightwatch & JavaScript and need some help with a nightwatch test: Here is what I want to do:
Step 1.refresh browser,
Step 2. check textValue of an element .
Repeat step1 then step2 until given timeout or textValue of element is same as expected value.
I have been trying to use while looping, however it didn't solve the problem. Here is what I have been working on for some time now.
function waitForText(browser) {
var sent = false;
var time = new Date();
time.setTime(Date.now());
while (!sent && (new Date().getTime() - time) < browser.timeout * 30) {
var status = "Sending";
browser.refresh();
browser.getText('#elementId', function (result) {
status = result.value;
if (status.indexOf("Sent") == 0) {
sent = true;
}
});
}
}

how can I add the ticking clock to my div in an existing code?

It's actually a follow up to this question I want to display elements from json based on their time and duration and interval is interupted by settimeout - I accepted the answer there made by #Daniel Flint - his code is quite clear and can be found here http://jsfiddle.net/nauzilus/rqctam5r/
However, there's one more thing that I wanted to add - a simple div <div id="time"></div> that would contain a new date time object initialized during opening the page and then it being incremented every second just to show the current time constantly. I thought about writing there a javascript:
var actualTime = new Date(substractedDate); // taken from the server
function updateTimeBasedOnServer(timestamp) {
var calculatedTime = moment(timestamp);
var dateString = calculatedTime.format('h:mm:ss A');
$('#time').html(dateString + ", ");
};
var timestamp = actualTime.getTime();
updateTimeBasedOnServer(timestamp);
setInterval(function () {
timestamp += 1000; // Increment the timestamp at every call.
updateTimeBasedOnServer(timestamp);
}, 1000);
(I provide the time of the server as a timestamp there).
I just noticed that there is a slight mismatch between displaying the time in my div and between the text appearing on the screen, possibly because I increment both of the values in two different places.
So my question is - how can I "merge" #Daniel Flint's code with mine and increment both values only in one place?

One thing that jumps out here:
timestamp += 1000;
setTimeout/setInterval aren't guaranteed to run at precisely the delay you've entered. Run this in your browsers console:
var last = Date.now(),
time = function() {
var now = Date.now();
console.log(now - last);
last = now;
},
id = setInterval(time, 1000);
On my Mac at home (Chrome/FireFox) it was anywhere from 990 to 1015. Windows machine at work is a bit better (995-1002), but IE was getting up to 1020. It's not a huge difference, but it's not nothing.
So code needs to be able to handle not running exactly every 1000ms. That's why I was running the timer at 500ms intervals, and checking if the start time was less-than-equal to the current time.
I've rejigged the demo to show the time and message in sync:
(function() {
var messages = [];
var time = document.getElementById("current-time");
var display = document.getElementById("message");
function check() {
showMessage(currentMessage());
showTime();
}
function currentMessage() {
var message = null;
if (messages.length) {
var now = toTheSecond(new Date());
var start = toTheSecond(new Date(messages[0].start_time));
var end = toTheSecond(new Date(start.getTime() + ( messages[0].text_duration * 1000 )));
if (start <= now) {
if (end <= now) {
// done with the current message...
messages = messages.slice(1);
// ...but check if there's another one ready to go right now
message = currentMessage();
}
else {
message = messages[0];
}
}
}
return message;
}
function toTheSecond(date) {
date.setMilliseconds(0);
return date;
}
function showMessage(message) {
if (message) {
display.textContent = message.text_content;
}
else {
display.textContent = "no messages";
}
}
function showTime() {
time.textContent = new Date().toLocaleString()
}
function getMessages() {
setTimeout(function() {
var now = new Date();
messages.push(
{"text_content":"aaaaa","text_duration":5,"start_time": new Date(now.getTime() + 3000).toISOString()},
{"text_content":"aawwaaaaa","text_duration":5,"start_time": new Date(now.getTime() + 10000).toISOString()},
{"text_content":"bbaawwaaaaa","text_duration":5,"start_time": new Date(now.getTime() + 15000).toISOString()}
);
}, 1000);
}
setInterval(check, 500);
getMessages();
})();
<span id="current-time"></span> <span id="message">Hello there!</span>
(Putting the code here as well because I recall SO want code in the answers so it's controlled, but there's a demo here: http://jsfiddle.net/nauzilus/ymp0615g/).
This probably isn't as efficient as it could be; the message text is being set every iteration which might cause repaints/reflow. But then again setting the time stamp is going to do that anyway, so meh :)

Candy Crush Saga Type countdown life system jQuery & Phonegap

I'm developing an app and I'm interested in ways to achive a Candy Crush Saga Type countdown life system.
My app is developed in phonegap (so html, css jquery and jquery mobile) and untill now I havn't figured out how to work with an external file as I'm thinking it's needed in this algorithm.
I want therefore to have 5 lives and each of them dissapears when the user fail or quit the lvl and regenerates after, lets say, 10 minutes. How can I keep the counter active if the app is closed?
Or a date substraction algorithm...
If somebody have knowledge in Phonegap I would be very grateful if he could help me with a jsfiddle wich I'll implement further in my app.
I'm also not sure what to use: localstorage vs DB
I'll give 50 of my bounty for the one who can help me with a jsfiddle example for this issue.
Thank you!

Edit: Sorry this is some pseudo code based off PHP - but you don't need crazy algorithms or anything
I don't write phone apps, but I know what you're trying to do and you're thinking about it too hard. You don't need to run the counter while the app is closed. You can save a timestamp from when the game is over, and reference it the next time the app is opened.
start_game();
if($lives > 0){ //run game
if($death === true){
$lives = $lives - 1;
$timer_value = date(Y-m-d h:i:s);
end_game($timer_value); //save starting time locally in "end_game" function
}
} else {
//buy more lives
}
Now let's say the user closes it and opens up. You can reference the current time versus the saved time. For every 10 minutes past then, add a life.
$old_time = strtotime($timer_value); //635393400
$cur_time = strtotime(date(Y-m-d h:i:s)); //635394600
if( $cur_time - $old time > 600 ) { $lives = $lives + 1; }
if( $cur_time - $old time > 1200 ) { $lives = $lives + 2; }
if( $cur_time - $old time > 1800 ) { $lives = $lives + 3; }
if( $cur_time - $old time > 2400 ) { $lives = $lives + 4; }
if( $cur_time - $old time > 3000 ) { $lives = $lives + 5; }
if( $lives > 5 ) { $lives = 5; }
That's some awful code lol, but you gut the idea. You don't need to run a timer in the background (you can't really with the app being closed, without doing some sort of server checks online, which is basically the same thing, but hosting all that personal life records in the cloud instead of on the phone.

In this code I use the localStorage since they are available on all platforms and web.
Using local storage you will get better cross platform compatibility:
WebStorage (localStorage & sessionStorage)
IndexedDB
SQL-Storage
Localstorage is array, but every element can only have string in it (using JSON we can store anything, that is not recursive). It is about 5MB for web. I guess it is limitless for mobile app. SessionStorage is deleted when user close browser and I am not sure how it will do on mobile.
Just a small date validator...
Date.prototype.isValid = function(first_argument) {
if ( Object.prototype.toString.call(this) !== "[object Date]" )
return false;
return !isNaN(this.getTime());
}
The main var declaration among retrieving variables from localStorage
var timeout = null;
var maxlife = 5;
if (undefined === localStorage.life) {
localStorage.life = maxlife;
}
if (undefined === localStorage.date||localStorage.date=="") {
localStorage.date = "";
var date = null;
}else{
var date = new Date(Number(localStorage.date));
if(!date.isValid()){
date = null;
}
}
var timeoutTime = 5 * 60000;
var life = Number(localStorage.life);
Lose life, set date if none exist yet. Set a timeout too and subtract life (& write it into localstorage).
function loseLife() {
if (null === date) {
date = new Date();
localStorage.date = date.getTime();
timeout = setTimeout(function(){addLife()}, timeoutTime);
}
life--;
localStorage.life = life;
lives.innerHTML = life;
console.log(life);
}
Add life, set date new date or reset the date completely. Set a timeout, if needed, and add a life (& write it into localstorage).
function addLife() {
life++;
localStorage.life = life;
if (life < maxlife) {
date = new Date();
localStorage.date = date.getTime();
timeout = setTimeout(function(){addLife()}, timeoutTime);
} else {
date = null;
localStorage.date = "";
}
lives.innerHTML = life;
}
Here you may need to change the hooks for blur (window not visible) and focus (window visible once again). Blur just clear timeout so it don't mess with us.
window.addEventListener('blur', function () {
clearTimeout(timeout);
});
This function check how many time it can subtract our time needed to get life from difference of now and the date we lost a life.
function tillNow(){
if (life < maxlife&&date!=null) {
var d = new Date();
var diff = d - date;
while (diff - timeoutTime > 0) {
diff = diff - timeoutTime;
if (life < maxlife) {
life++;
console.log("add");
}else{
date = null;
localStorage.date = "";
break;
}
}
localStorage.life = life;
if (life < maxlife) {
date = new Date((new Date()).getTime()-diff);
localStorage.date = date.getTime();
timeout = setTimeout(function(){addLife()}, timeoutTime-diff);
}
}
lives.innerHTML = life;
}
Focus just call tillNow()
window.addEventListener('focus', function () {
tillNow();
});
Onload do the same as focus, but fills the div with a value initially...
window.onload=function(){
var lives = document.getElementById("lives");
lives.innerHTML = life;
tillNow();
}
Demo sorry couldn't do jsFiddle of codepen since they don't like local storage. (the demo use 15sec as timer to get new life ;) I am impatient )

I would use logic similar to what Xhynk suggested. I would use a variable like milisecondsUntilYouGainALife and when you lose the first life, set this variable = 1000ms*60sec*10min = 600000. Then first line (or so) in main loop, record the current time. next time it hits the loop also record the time and subtract the difference from milisecondsUntilYouGainALife. If < 0, lives++. Also make sure in your "close the app" function you record the time and check that time in the main loop.
pseudocode:
function game(){
...
while(mainLoop){
oldTime = curTime
curTime = GetTime() //I Forget the exact code to get the miliseconds
deltaTime = curTime - oldTime
if(deltaTime > milisectionsUntilYouGainALife){
if(lives < MAX_LIVES){
lives++
milisecondsUntilYouGainALife - deltaTime
}
}
}
}
function AppClosing(){
curTime = GetTime()
}
function LoseALife(){
milisecondsUntilYouGainALife += 600000
}
There may be something im missing, but this should get you on the right track!
