if statement using onchronometerticklistener - javascript

I'm trying to create some time based events using a chronometer. The code below is successfully displaying a toast after 5 seconds of chronometer being started however I need the toast to be displayed at 5/10/20 seconds.
I've tried using if (elapsedTime == 5000 ||elapsedTime == 10000 ) but no toast displays when I use ==.
Any ideas?
Chronometer.OnChronometerTickListener mChronoListener = new OnChronometerTickListener() { // listens to journey timer to initiate time based events
public void onChronometerTick(Chronometer arg0) {
long elapsedTime = SystemClock.elapsedRealtime() - arg0.getBase();
if (elapsedTime > 5000)
{
Toast.makeText(SafeDrive3Activity.this, "HOUR PASSED", Toast.LENGTH_LONG).show();
}
}
};

Try something like this (if you want to keep it going every 10 seconds thereafter):
Chronometer.OnChronometerTickListener mChronoListener = new OnChronometerTickListener() {
// listens to journey timer to initiate time based events
int currentNeededTime = 5000;
public void onChronometerTick(Chronometer arg0) {
long elapsedTime = SystemClock.elapsedRealtime() - arg0.getBase();
if (elapsedTime > currentNeededTime)
{
Toast.makeText(SafeDrive3Activity.this, "HOUR PASSED", Toast.LENGTH_LONG).show();
currentNeededTime += currentNeededTime == 5000 ? 5000 : 10000;
}
}
};

How to display notification if request takes a certain amount of time?

This is what i've done:
response.config.responseTiming = performance.now();
var timing = response.config.responseTiming - response.config.requestTiming;
if (timing > 15000) {
var toastr = $injector.get('toastr');
toastr.info($filter('i18n')('_request_info_'));
angular.extend(toastrConfig, {
preventOpenDuplicates: true
});
}
But the problem is, the notification will appear when the request is completed, not when 15-sec pass(example: if it goes over 30sec, it will display notification after 30 sec not on 15 sec). Any idea how to do this?

seekTo() is not a function YouTube iframe API error

I am using a Wordpress plugin to add timestamp links of videos that will seek the video automatically to a certain timeframe.
Javascript:
function onYouTubeIframeAPIReady(){
console.log('Confirmation of call to onYouTubeIframeAPIReady()');
var STT = {
settings: STTSettings,
media: undefined,
skipTo: undefined,
isHTML5: false,
isYoutube: true,
doHTML5Skip: function() {
STT.media.removeEventListener('canplaythrough', STT.doHTML5Skip);
STT.media.currentTime = STT.skipTo;
STT.media.play();
},
doYoutubeSkip: function() {
STT.media.seekTo(STT.skipTo);
STT.media.playVideo();
}
};
STTSkipTo = function(time) {
var audio = document.getElementsByTagName('audio'),
video = document.getElementsByTagName('video'),
iframe = document.getElementsByTagName('iframe'),
timeArray = time.split(':').reverse(),
seconds = parseInt(timeArray[0]),
minutes = timeArray.length > 1 ? parseInt(timeArray[1]) : 0,
hours = timeArray.length > 2 ? parseInt(timeArray[2]) : 0;
STT.skipTo = seconds + (minutes * 60) + (hours * 3600);
if (STT.media) {
console.log(STT.media.seekTo);
STT.doSkip();
return;
}
if ((parseInt(STT.settings.link_audio) && audio.length) ||
(parseInt(STT.settings.link_video) && video.length))
{
STT.doSkip = STT.doHTML5Skip;
if (parseInt(STT.settings.link_audio) && audio.length) {
STT.media = audio[0];
} else {
STT.media = video[0];
}
STT.media.addEventListener('canplaythrough', STT.doHTML5Skip);
STT.media.load();
STT.media.play();
return;
} else if (parseInt(STT.settings.link_youtube && iframe.length)) {
// Inspect the iframes, looking for a src with youtube in the URI
for (var i = 0; i < iframe.length; i++) {
if (iframe[i].src.search('youtube') !== -1) {
// Set up the JS interface
STT.doSkip = STT.doYoutubeSkip;
iframe[0].id = 'stt-youtube-player';
STT.media = new YT.Player('stt-youtube-player', {
events: {
onReady: STT.doYoutubeSkip
}
});
return;
}
}
}
console.log('Skip to Timestamp: No media player found!');
return;
}
}
On my localhost, the plugin works seamlessly but on my hosted website, I get the following error with the stack as follows:
Uncaught TypeError: STT.media.seekTo is not a function
I think for some reason the website is unable to load the www-widgetapi.js which is a dependency for YouTube iframe API and thus is unable to generate the required function definition. However, I did try to include the script manually in the header but it still didn't work.
If anyone knows of any other wordpress plugin, please advice.
Based from this documentation, you need to set both the two parameter of the player.seekTo(seconds:Number, allowSeekAhead:Boolean).
Seeks to a specified time in the video. If the player is paused when the function is called, it will remain paused. If the function is called from another state (playing, video cued, etc.), the player will play the video.
The seconds parameter identifies the time to which the player should advance.
The player will advance to the closest keyframe before that time unless the player has already downloaded the portion of the video to which the user is seeking.
The allowSeekAhead parameter determines whether the player will make a new request to the server if the seconds parameter specifies a time outside of the currently buffered video data.
It should be like: Player.seekTo(120, true)//120 seconds

How to approach a setInterval triggering a setInterval within the same function

I a rewards site. Users earn points when they watch videos. Users want to skip to the end of the video to quickly earn their points. Therefore, the mechanism of the video being marked as completed is managed by a JS timer.
The Problem: When a user pauses the video, the timer needs to pause. When the user clicks play again, a setInterval is used to reopen the function, where a setInterval within the existing function does the same thing, creating a huge problem...
This is the code that is set every second to update the timer...
var video_percent_count = 0;
function video_percent() {
var prize_video = document.getElementById("prize_video");
total_duration = Math.floor(prize_video.duration) + 1;
video_percent_count++;
percent = video_percent_count / total_duration;
convert_percent = (percent * 100).toFixed(2);
if(convert_percent == 100) {
clearInterval(video_percent_interval);
}
if(prize_video.paused) {
clearInterval(video_percent_interval);
}
if(prize_video.play) {
setInterval("video_percent()", 1000);
}
$(".percent_container").text(convert_percent);
}
function prize_video(count_prize) {
var back_count_prize = count_prize - 1;
$("#prize_video").get(back_count_prize).play();
video_percent_interval = setInterval("video_percent()", 1000);
}
How can I properly manage play and pause and still keep setInterval clean?

JQuery progress bar pauses when browser tab is changed

I'm trying to display a progress bar on a html page using javascript. However,
when the browser tab containing the code becomes inactive, the progress bar stops updating,
being resumed when the tab is active again.
How can I prevent the browser from stopping/pausing the execution of javascript code when the window is inactive?
Although it may be irrelevant, here is the code:
Object.progressBar = function(){
$( "#question-progress-bar" ).progressbar({
value: false,
complete: function(event, ui) { ... }
});
var seconds = 15.0,
progressbar = $("#question-progress-bar"),
progressbarValue = progressbar.find(".ui-progressbar-value");
progressbarValue.css({
"background": '#c5b100',
"opacity" : '0.8'
})
var int = setInterval(function() {
var percent = (15-seconds)/15*100;
seconds=seconds-0.1;
progressbar.progressbar( "option", {
value: Math.ceil(percent)
});
$("#question-progress-bar-seconds").html((seconds).toFixed(1)+"s");
if (seconds <= 0.1) {
clearInterval(int);
}
}, 100);
}
Instead of using setInterval and assuming a certain amount of time has passed between calls (even when it's up front, setInterval has hit or miss accuracy) use the Date object to get a time when the bar starts, and compare that to the current time at each iteration.
<html>
<head>
<script>
function go()
{
var pb = new ProgressBar(5, "targ");
}
window.onload = go;
function ProgressBar(l, t)
{
var start = Date.now();
var length = l * 1000;
var targ = document.getElementById(t);
var it = window.setInterval(interval, 10);
function interval()
{
var p = 100 * (Date.now() - start) / length;
if(p > 100)
{
p = 100;
window.clearInterval(it);
alert("DONE"); // alternatively send an AJAX request here to alert the server
}
targ.value = (Math.round(p) + "%");
}
}
</script>
</head>
<body>
<input type="text" id="targ" />
</body>
</html>
I've made an example object, here, that immediately starts a countdown when instantiated and calls an alert and kills the interval timer when done. Alternatively an AJAX call, or any other sort of call can be done upon completion.
It should be noted that this will NOT complete the call if the browser stops Javascript all together. It will, however, complete it as soon as the tab has been given focus again if enough time has passed in the interim. There is no way for a website to alter this sort of browser behavior from the scripting side.
Hope that helps!

Combine ASP.net AJAX timer with javascript countdown

I am currently working on porting a vb.net winforms program over to a web based version, and one of the functions in the original program has be stumped.
In the original program, every 5 minutes, a form pops up for user input. There is also a label control on the main form which counts down to the next popup. This is accomplished with a single timer control with a 1 second duration. every tick, it decrements the countdown, and when the countdown reaches 0, it pops up the form and then resets. Simple enough, but in my web app, I can't afford to be doing a postback every second, so what I am attempting is to combine a javascript countdown widget with an AJAX timer. Essentially, what should happen is that when the page loads, the countdown begins decrementing from 300 seconds, and the AJAX timer begins with a duration of 300 seconds. My idea is that when the timer ticks, it will run my function, as well as reset the countdown to 300 seconds again.
My problem, is that I am not able to reset the countdown with the code that I have, and I know that I am doing something (likely very simple) wrong, but I don't know enough Java to know what.
If I hardcode the Timer var to 300, the countdown works, and the timer ticks (fires the additional functons), but the countdown just keeps counting down (into negative numbers). How do I reset the countdown variable from code behind?
Here is the countdown function
var Timer = <%= CountDown %>;
function updateClock() {
// Update Countdown
Timer -= 1;
var TimerMin = Math.floor(Timer / 60);
var TimerSec = Timer - (TimerMin * 60);
TimerSec = (TimerSec < 10 ? "0" : "") + TimerSec;
var TimerFormat = TimerMin + ":" + TimerSec;
// Update the countdown display
document.getElementById("javaCountdown").firstChild.nodeValue = TimerFormat
}
Here is the body code
<body onload="updateClock(); setInterval('updateClock()', 1000 )">
And the Code Behind
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Countdown = 300
End Sub
PProtected Sub Timer1_Tick(ByVal sender As Object, ByVal e As EventArgs) Handles Timer1.Tick
Countdown = 300
'Additional Functions
End Sub
This solution uses jQuery.
<script>
var intervalSecond = null;
var interval5minutes = null;
$(document).ready(function() {
// enable both intervals
enableIntervals();
// onsubmit event for your form
$("#popupForm").submit(function() {
// hide the form again
$("#popupForm").css("display", "none");
// enable intervals again.
enableIntervals();
});
});
function enableIntervals() {
// every second interval
intervalSecond = setInterval(function() {
$("#updateMeEverySecond").html(new Date());
}, 1000);
// every 5 minutes interval
interval5minutes = setInterval(function() {
// display form and shut off the interval timers
$("#popupForm").css("display", "block");
clearInterval(intervalSecond);
clearInterval(interval5minutes);
}, 5 * 60 * 1000);
}
</script>
<div id="popupForm" style="display:none;">
<form>
<input type="text" />
</form>
</div>
<label id="updateMeEverySecond">Test</label>
