I'm not sure how to word this but is it possible to use the information I've captured and then play it back to the user?
for example.
User presses btn1, btn2 and btn3 (there is a separate sound that
responds to each button click)
Which button and time it was pressed is stored into an empty array ([{"time":1176,"elemId":"btn1"},{"time":1554,"elemId":"btn2"}])
Array is then saved into local storage
Array is then retrieved from local storage
Now from this point is it possible to playback the information in the array to mimic exactly what the user did?
Apologies if this is too vague but I'm not entirely sure what I'm looking for, thanks in advance!
EDIT: This is all I have so far, I can retreive my array and it shows in my console log but I can't think of how to progress from this point .
function get() {
// Retrieve the object from storage
var value = localStorage.getItem("eventlist");
console.log('value: ', JSON.stringify(value));
}
Here's a fiddle I wrote: http://jsfiddle.net/n6R9S/1/
I didn't assume jQuery, although that would have been easier for me.
The function-in-a-function in the timeout is due to a scoping issue.
var playback = [{
"time": 1176,
"elemId": "btn1"
}, {
"time": 1554,
"elemId": "btn2"
}]
// Do we assume that the array is in order? If not, we have to re-order it to make sure.
var output = document.getElementById('output');
document.getElementById('btn1').onclick = function () {
output.innerHTML += '1';
}
document.getElementById('btn2').onclick = function () {
output.innerHTML += '2';
}
for (i = 0; i < playback.length; i++) {
play = playback[i];
setTimeout((function (play) {
return function () {
document.getElementById(play.elemId).onclick();
}
})(play), play.time)
}

I have a tricky requirement which im not able to fix.
I have a button and if i click on that button, Im getting below data from a REST web service ..
{
"results": [{
"Reqdate": "\/Date(1520899200000)\/",
"Tooltip": "13.03.2018 Blood Donation Approved ",
"Legendid": "GROUP_LEVEL1"
},{
"Reqdate": "\/Date(1523836800000)\/",
"Tooltip": "16.04.2018 Privilege Leave Sent ",
"Legendid": "BADVALUE_LIGHT",
},{
"Reqdate": "\/Date(1524528000000)\/",
"Tooltip": "24.04.2018 Privilege Leave Sent ",
"Legendid": "BADVALUE_LIGHT",
}]
}
If im getting the above data for the first time. Im going to display one section. Now again if i click on the same button, If i get the same data in the service then i have to hide the section. But im not able to check the same data for the second time.
Im trying to fix this issue by storing the data in a variable like below..
var firstTimeResults = data.results;
Now im not able to check if the same data is coming for the second time. Actually im not able to produce the sample code too. Im sorry for that
Can someone please help me to fix this issue.
I am not fully understand your problem but I think you can store your data as JSON and check if the same data is return from the second time onwards?
Code example
// Variable declaration
var firstTimeResults = null;
// When data return
var dataJson = JSON.stringify(data.results);
if (firstTimeResults === null) {
firstTimeResults = dataJson;
}
else {
// check to see if the data is the same as the firstTimeResults
var isSame = firstTimeResults === dataJson;
if (isSame) {
// Same
} else {
// Not the same
}
}
You can simply try with Lodash library.
It makes JavaScript easier to work with arrays, numbers, objects, strings, etc.
https://lodash.com/
var firstResult = null;
var secondResult;
var showSection;
function getData() {
// here goes your API request to get the data
};
function onButtonClick() {
this.getData().then(function(value) {
if !(firstResult) {
firstResult = value;
showSection = true;
return;
}
secondResult = value;
if (_.isEqual(firstResult, secondResult)) {
showSection = false;
}
})
};
Hope this will be helpful to you!
I am trying to create a chrome extension for Twitch and I'm facing a small issue which I cannot figure out how to solve. I must say my javascript knowledge is not the best (I am a C# developer) and this time not even google could help me (maybe because I don't know the correct search terms).
So to the problem. The goal of this extension is to notify you when a streamer changes games during live stream. I would like to notify the user only once per game changed. I have an array which contains objects, this object is a class with some properties, one of the properties is game. This array is then parsed into a json string to be saved in the browser localstorage. Below is the code i'm using to check what game is the streamer playing and trying to set the property game to that value. Then parsing the array back to json string and set the localstorage.
function checkPlaying() {
var twitchUsers = JSON.parse(localStorage.twitchUsers);
if (twitchUsers.length > 0) {
var f = (function () {
var xhr = [];
for (i = 0; i < twitchUsers.length; i++) {
(function (i) {
if (twitchUsers[i].isOnline) {
xhr[i] = new XMLHttpRequest();
xhr[i].open('GET', REQUEST_BASE + REQUEST_CHANNELS + twitchUsers[i].id, true);
xhr[i].setRequestHeader('Accept', 'application/vnd.twitchtv.v5+json')
xhr[i].setRequestHeader('Client-ID', CLIENT_ID)
xhr[i].onreadystatechange = function () {
if (xhr[i].readyState == 4 && xhr[i].status == 200) {
var response = JSON.parse(xhr[i].responseText);
var currentGame = response.game;
if (twitchUsers[i].game != currentGame) {
twitchUsers[i].game = currentGame;
if (twitchUsers[i].notify) {
browser.notifications.create({
"type": "basic",
"iconUrl": twitchUsers[i].logo,
"title": "TwitchWatcher",
"message": twitchUsers[i].name + ' is currently playing ' + twitchUsers[i].game
});
}
}
}
};
xhr[i].send();
}
localStorage.twitchUsers = JSON.stringify(twitchUsers);
})(i);
}
})();
}
}
The issue is that localStorage.twitchUsers never gets the new values, and this causes the extension to keep notifying the user with the same game.
I have tried to change the position of localStorage.twitchUsers = JSON.stringify(twitchUsers); to inside of the for loop and to the outside of the f variable, but I had no success.
Does anyone know what am I doing wrong?
Thank you.
How can I set the badge number on a specific tab only? So far I have a code that sets the badge number on all the tabs.. I've been reading around A LOT, but there doesn't seem to be a whole lot of information about this, so perhaps I will find a solution for this here.
I would like something like Adblock Plus, which sets the badge number for a specific tab. This is pretty easy in Chrome etc, but doesn't seem to be the case in Safari.
Does anyone know how extensions like Adblock plus shows the badge number on a specific tab?
So far I only have this code, but as mentioned, it sets the badge on all the tabs, which is not the result I want.
safari.extension.toolbarItems[0].badge = 2;
Edit:
I have been looking at the source code of Adblock plus, and a few other extensions that had this function. And it seems it is using some prototype.
Adblock plus background snippet:
BrowserAction.prototype = {
_set: function(name, value)
{
var toolbarItem = getToolbarItemForWindow(this._page._tab.browserWindow);
if (!toolbarItem)
{
return;
}
var property = toolbarItemProperties[name];
if (!property)
{
property = toolbarItemProperties[name] = {
pages: new ext.PageMap(),
global: toolbarItem[name]
};
}
property.pages.set(this._page, value);
if (isPageActive(this._page))
{
toolbarItem[name] = value;
}
},
setIcon: function(path)
{
this._set("image", safari.extension.baseURI + path.replace("$size", "16"));
},
setBadge: function(badge)
{
if (!badge)
{
this._set("badge", 0);
}
else if ("number" in badge)
{
this._set("badge", badge.number);
}
}
};
Content script (adblockplus.js)
FilterNotifier.on("filter.hitCount", function(filter, newValue, oldValue, page)
{
if (!(filter instanceof BlockingFilter) || !page)
{
return;
}
Prefs.blocked_total++;
var blocked = blockedPerPage.get(page) || 0;
blockedPerPage.set(page, ++blocked);
if (Prefs.show_statsinicon)
{
page.browserAction.setBadge(
{
color: badgeColor,
number: blocked
});
}
});
It seems this is how Adblock plus does it, but so far I haven't been able to replicate it. Still trying though..
Okay, so I finally found a solution for this, and thought I would share what I did, in case somebody else is in the same situation.
This morning I got the idea of storing the data in an array, when the user visits one of the websites I want to display the badge number on (doesn't store all websites the user visits), only if it matched one of the websites I wanted to target. I stored the following data in the array: root domain (example.com) and the badgeNumber.
For this to work, you need to make an array of the root domain of the websites you want to target, and then only execute the following when it matches, otherwise the array would fill up very quickly, and we don't want too much data in it.
In the global page, start by making an empty array to store the data
var badgeUpdateArray = [];
You then need to set up message handling in your global page as well.
safari.application.addEventListener('message', handleMessage, false);
function handleMessage(event) {
if(event.name === "setBadgeText"){
var id = badgeUpdateArray.length + 1;
var isFound = 0;
var found = badgeUpdateArray.some(function (el) {
if(el.identifier === event.message.identifier){
// Was found
isFound = 1;
}
});
if (isFound == 0) {
// Not found, add to the array
badgeUpdateArray.push({identifier:event.message.identifier,badgeNumber:event.message.badgeNumber});
}
// Set the badge number
safari.extension.toolbarItems[0].badge = event.message.badgeNumber;
}
}
Now we need to send the message from the content script to the global page. You need to get the root domain (example.com), I'm not getting into that here, as it's pretty easy. You will also need the badgeNumber value, this can be gathered from wherever (GET request, or elsewhere..)
Remember, only execute this code if the website matches your target domains.
var message = {
identifier: domain,
badgeNumber: rows.length
}
safari.self.tab.dispatchMessage("setBadgeText", message);
This will send the message, and store the data in the array, it will also set the badge number.
Now, for this to be working on different tabs, you will need to make an event handler for "activate" on the global page, this will run whenever a tab is active.
safari.application.addEventListener("activate", updateBadge, true);
function updateBadge(){
var cDomain = safari.application.activeBrowserWindow.activeTab.url;
cDomain = cDomain.replace("www3.","");
cDomain = cDomain.replace("www2.","");
cDomain = cDomain.replace("www1.","");
cDomain = cDomain.replace("www.","");
cDomain = new URL(cDomain);
cDomain = cDomain.hostname;
var id = badgeUpdateArray.length + 1;
var isFound = 0;
var badgeNumber = 0;
var found = badgeUpdateArray.some(function (el) {
badgeNumber = el.badgeNumber;
if(el.identifier === cDomain){
// Was found, set the badge number
isFound = 1;
safari.extension.toolbarItems[0].badge = el.badgeNumber;
}
});
if (isFound == 0) {
// Was not found
safari.extension.toolbarItems[0].badge = 0;
}
}
Hopefully I've got it all in here, and at least something that works, though I have to say that I would prefer an easier way of storing it.. like Chrome etc does it, with the tab API.
I am having an interesting issue. The general idea of what I am doing is pulling data from a Firebase database, and populating a table based on that data. Everything runs perfectly during initial population--cells and rows are populated as they should be, but the weird issue is that the scripts seem to execute again randomly. I've logged the incoming data to the console, and can see it print twice after some amount of time.
This second execution does not happen if I am to navigate between pages, or reload the page--in either of those cases everything works as it should. The problem SEEMS to happen when I log back into my computer after locking it??? Does anybody have ANY idea what could be going on here? Relevant portion of script below:
const table = document.getElementById('myTable');
firebase.auth().onAuthStateChanged(firebaseUser => {
if (firebaseUser) {
let user = firebase.auth().currentUser;
let uid = user.uid;
const dbRef = firebase.database().ref().child("data/" + uid);
dbRef.once('value', snap => {
var dataCount = snap.child("secondData").numChildren();
var datalist = snap.child("secondData").val();
var dataArray = Object.keys(datalist).map(function(k) {
return datalist[k]
});
pullAllInfo(dataCount, dataArray);
});
}
});
function pullAllInfo(count, array) {
let k = 0;
let dataArray = [];
for (i = 0; i < count; i++) {
let specificRef = firebase.database().ref().child("secondData/" + array[i]);
specificRef.once('value', snap => {
var optionsTag = array[k];
k++;
var dataId = snap.child("id").val();
var dataName = snap.child("name").val();
var dataCount = snap.child("data").numChildren();
dataArray.push(dataId, dataName, dataCount, optionsTag);
if (k == count) {
buildTable(dataArray);
console.log(dataArray);
}
});
}
}
As you can see from the code above I AM calling .once() for each reference, which would prevent data duplication from the typical .on() call. Just cant seem to figure this one out. ALSO I have an iMac, just for anyone curious about my potential computer unlock diagnosis.
Thanks all!
Most likely, the auth state is changing and setting off your function. Try throwing a log under firebase.auth().onAuthStateChanged like this:
firebase.auth().onAuthStateChanged(firebaseUser => {
console.log( 'auth state changed', firebaseUser );
if (firebaseUser) {
My guess is that you'll see that the AuthState is changing when you log out/log in from your computer.
I solved this issue by creating another global boolean called preLoaded. At the beginning, it is set to false and, once the data is loaded and passed off to build the table, it is set to true. It now looks like this:
if(k == count && preloaded == false){
preloaded = true;
console.log(dataArray);
buildTable(dataArray);
}
All set!
I'm busy with a webdoc that I'm partially creating on hype, the video are hosted on vimeo (so I need to use the vimeo api for some tasks like seekto) but my difficulties should be limited to js.
the objective is to display a given image at a given time interval of the video.
With my code below, I do get the string "test", "success" and "confirmed success" at the right time in my div id=popimgbox, and I can seek back and forth in the video and still get the right "answear", if I may say so.
Now, I have images that are all stored in the same folder, and all named popimgX.jpg, with X being a number.
I want
to store the URLs of my images in a variable let's say "popimgurl"
that my variable is updated (by a function???) in order to contain the URL of a given immage for a given interval of time of the video
to still be able seekto back and forth in the video and get the right URL at the right time
To do so I created a function increment, and a pair of variable. With the code below, my popimgurl variable is indeed updated once the video reach 3 seconds, but it do not increment only once... untill the video reach 6 seconds, when I want to update my popimgurl variable once again.
I tried to use for with js break and js closure but did not manage for some understandable reasons after thought;
I did quite some try with switch, but I'm stuck with the fact that the case must be string or single numerical value, not numerical interval or comparaison.
thank's in advance for your help :-)
var iframe = $('#vplayer_1')[0];
var player = $f(iframe);
var status = $('.status');
fired = 0;
//my try to sync increment
var dia = (function () {
var n = 0;
return function increment() {return n += 1;}
})();
function dian(){
popimgurl = '${resourcesFolderName}/popimg'+ dia() +'.jpg';
popimgloader = '<img src ="' + popimgurl + '">';
}
// When the player is ready, add listeners for pause, finish, and playProgress
player.addEvent('ready', function() {
status.text('ready');
player.addEvent('pause', onPause);
player.addEvent('finish', onFinish);
player.addEvent('playProgress', onPlayProgress);
});
// Call the API when a button is pressed
$('button').bind('click', function() {
player.api($(this).text().toLowerCase());
});
function onPause(id) {
status.text('paused');
}
function onFinish(id) {
status.text('finished');
}
function onPlayProgress(data, id) {
status.text(data.seconds + 's played');
//my chapters, when I want the img to change within popimgbox
if (data.seconds >= 1) {
popimgbox.innerHTML = "test";
}
if (data.seconds >= 3) {
// popimgbox.style.display = "success"
dian();
popimgbox.innerHTML = popimgurl;
}
if (data.seconds >= 6) {
// popimgbox.style.display = "confirmed success"
dian();
popimgbox.innerHTML = popimgurl;
}
}
PS1: disclamer, I'm a beginer coder, i do my best so excuse my french if my question isn't well formulated or if the answer is somewhere but I was unable to see/understand it
PS2 : i did quite a try with popcornjs, but not way to make it work with vimeoapi and within hype, quite frustrated ;-)
PS3: as this is my first post I would like to thank's you all for the great support available here; I owe you most ;-)
Finally I'll answer myself.
It's a solution that only stand for vimeo, as this is what I use to host my videos, but very little changes have to be done to work with the html5 <video> tag as well.
First you need to define your variables and your intervals:
var intervals =[11.56, 44.08, 115, 125, 127.92, 177.72];
var index;
Then you need to add an event listener timeupdate that return the elapsed time , filter intrevals according to the elapsed time data.seconds or seconds and define the value of index as the indexOf the last entry of your filtered array intervals
player.on('timeupdate', function(data) {
seconds = data.seconds;
index = intervals.indexOf(intervals.filter(function(nb) {
return seconds < nb;
})[0]);
if (diaIndex == -1) {
// do something if seconds > the higher value of your last interval
}
And that's it !
Now for
seconds = [0, 11.56[ --> index = 0
seconds = [11.56, 44.08[ --> index = 1
seconds = [44.08, 115[ --> index = 2
and so on
Now we can use index as a variable for instance to display a given image :
var imgNum = 0;
function diaplayImg(index) {
if(index === imgNum) {
return;
// this will avoid that the same image is releaded on every timeupdate events
}
else {
imgNum =+ index
document.getElementById('myImageWraper').innerHTML = "<img src='img" + imgNum+ ".png'>"
};
}
Don't forget, you need to call the function displayImage() in your timeupdate event listener, it will then be fired every ±250ms but the image won't be reloaded each time
PS : vimeo has realeased its new api between my question and my answer so the question use the old api while the answer use the new one
