HTML5 audio won't play sometimes

In my application, I am creating 10 audio object and I store them in a browser variable. Based on the scenario, I will pick one of them and will assign it to one global variable. Then I play that sound. After some time I will stop and clear that audio from the global variable.
I am verifying the readystate whenever I play the sound. I capture Play & Pause events.
The problem is that sometimes the sound is not audible but play & pause events are still fired. I am not able to reproduce it all the times (it happens randomly).
Please let me know if anyone faced this kind of issue.
function Sound(){}
try
{
if(new Audio().canPlayType("audio/wav") != "" && new Audio().canPlayType("audio/wav") != "no" ){
Sound.extn="wav";//No I18N
}
else{
Sound.extn="mp3";//No I18N
}
}
catch (e) {
}
Sound.init=function(soundsobj)
{
for (var tunename in soundsobj)
{
var audioobj = new Audio(soundsobj[tunename]);
audioobj.setAttribute("autobuffer", "true");
audioobj.addEventListener('loadeddata', function() {
Sound.cache[tunename]=this;
});
audioobj.addEventListener('loadedmetadata', function() {
this.currentTime = 0;
});
Sound._SOUND_PLAYER.addEventListener( "play", function(){console.log(this.readyState);}, false);
Sound._SOUND_PLAYER.addEventListener( "pause", function(){console.log(this.readyState);}, false);
}
}
Sound.playTune=function(tunename,duration)
{
if(Sound.cache[tunename])
{
var cachedsound = Sound.cache[tunename];
if(cachedsound.readyState == 4)
{
cachedsound.currentTime = 0;
Sound._SOUND_PLAYER = cachedsound;
Sound.play(duration);
}
else
{
delete Sound.cache[tunename];
var audioobj = new Audio(soundsobj[tunename]);
audioobj.setAttribute("autobuffer", "true");
audioobj.addEventListener('loadeddata', function() {
Sound.cache[tunename]=this;
Sound._SOUND_PLAYER = this;
Sound.play(duration);
});
}
}
}
Sound.play = function(duration)
{
Sound._SOUND_PLAYER.loop=true;
Sound._SOUND_PLAYER.play();
clearTimeout(Sound.cleartimer);
Sound.cleartimer = setTimeout(function(){Sound.stop()},duration*1000);
}
Sound.stop=function()
{
try
{
if(Sound._SOUND_PLAYER)
{
Sound._SOUND_PLAYER.pause();
}
Sound._SOUND_PLAYER = undefined;
}
catch(e){}
}

custom when statement not firing functions

I am trying to make a when statement but it is not working as planned. Basically its a function to call another function when try. First before I explain further here is the syntax
when(function() {
//code here
});
Now basically... Think this way.. We have a progressbar.. We also have a custom event such as...
var pBarEvent = document.createEvent('Event');
pBarEvent.initEvent('pbardone', true, true);
document.addEventListener('pbardone', function() {
//code here
});
//if progress bar reaches 100 dispatchEvent
if (document.querySelector(".progress-bar").style.width === 100 + "%")
{
document.dispatchEvent(pBarEvent);
}
Now that piece of code is an example. If the document loads and its for instance at 50% it wont trigger until you add another event such as keydown or click. I dont want to do that I want to do.... "when" progress bar width equals 100% trigger it. Thats basically what needs to happen. So here is the code for the when statement so far (keep in mind its not the best looking one. As I dont normally do this but I wanted to keep this dynamic and who knows someone who later wants to do this can look at this question)
when function
function when(func)
{
var nowActive = false;
if (!typeof func === 'undefined')
{
func = new Function();
}
if (func)
{
nowActive = true;
clearInterval(whenStatementTimer);
}
else
{
nowActive = false;
var whenStatementTimer = setInterval(function() {
switch(func)
{
case true:
{
nowActive = true;
when();
break;
}
case false:
{
nowActive = false;
when();
break;
}
}
}, 1000);
}
if (nowActive === true)
{
func();
}
}
Now this does not work when I go to try something like....
when(function() {
SmartLeadJS.SmartLeadEvents.customEvents.progressBarFull(function() {
alert("100%");
SmartLeadJS.SmartLeadAds.LeadView.ChromeExtension.General.DynamicStyles.$.style("body", "background", "black");
});
});
It does not trigger. I need help possibly getting this when statement to work. What am I doing wrong? What can I do to fix it? No errors get thrown but it never fires.
edit based on answer
Function tried
function when(currentValue)
{
try
{
var o = {};
o.currentValue = currentValue;
o.do = function(func)
{
if (!typeof func === 'undefined')
{
func = new Function();
}
if (this.currentValue)
{
func();
}
else
{
setTimeout(this.do(func), 100);
}
};
return o;
}
catch(e)
{
console.log(e);
}
}
used as
when(true).do(function() {
SmartLeadJS.SmartLeadEvents.customEvents.progressBarFull(function() {
alert("This divs going through changes!!");
SmartLeadJS.SmartLeadAds.LeadView.ChromeExtension.General.DynamicStyles.$.style(".div", "background", "black");
});
});
This does not work. It never fires. But if I use a onclick listener as such it fires
document.addEventListener("click", function() {
SmartLeadJS.SmartLeadEvents.customEvents.progressBarFull(function() {
alert("This divs going through changes!!");
SmartLeadJS.SmartLeadAds.LeadView.ChromeExtension.General.DynamicStyles.$.style(".div", "background", "black");
});
}, false);

function when(statement){
o={};
o.statement=statement;
o.do=function(func){
awhen(this.statement,func);
};
return o;
}
function awhen(statement,func){
if(eval(statement)){
func();
}else{
window.setTimeout(function(){awhen(statement,func);},100);
}
}
Use:
when("true").do(function(){});
It works now :) . Its important to put the condition in ""!

Jquery function is starting on click but I need to stop it

I always wonder that onclick functions start to a javascript or jQuery, but How does it stop? Finally, I faced with a function in my learning progress. May you help me to find a solution?
I want to stop this function on another onclick:
function live_preview() {
var icon = document.getElementById('LivePreIcon');
if (icon.classList.contains('fa-eye-slash')) {
icon.classList.remove('fa-eye-slash');
icon.classList.add('fa-eye');
$('#result').keyup(function () {
$('#dialog').html($(this).val());
});
return;
}
if (icon.classList.contains('fa-eye')) {
icon.classList.remove('fa-eye');
icon.classList.add('fa-eye-slash');
// Stop the jquery function here
return;
}
}

var play=0;
function live_preview() {
var icon = document.getElementById('LivePreIcon');
var play;
if(!play){
if (icon.classList.contains('fa-eye-slash')) {
icon.classList.remove('fa-eye-slash');
icon.classList.add('fa-eye');
$('#result').keyup(function () {
$('#dialog').html($(this).val());
play = 1;
});
return;
}
}
else{
if (icon.classList.contains('fa-eye')) {
icon.classList.remove('fa-eye');
icon.classList.add('fa-eye-slash');
play=0;
return false;
// Stop the jquery function here
}
}
}

not .isAfter jQuery Ajax

I am trying to show separate messages if a div exists after a certain div or does not exist based the end of an ajax function
Here is the code I came up with:
.ajaxComplete(function() {
// Pilots page code.
if ($('body').hasClass('page-pilots')) {
$.fn.isAfter = function(sel) {
return this.prevAll(sel).length !== 0;
}
$('#quicktabs-tabpage-107_display-0 .view-content').each(function() {
if ($(this).isAfter("#quicktabs-tabpage-107_display-0 .view-filters")) {
console.log(".view-content is after, hide message");
$('.pilots-result-message').hide();
}
if (!$(this).isAfter("#quicktabs-tabpage-107_display-0 .view-filters")) {
console.log(".view-content is not after, show message");
$('.pilots-result-message').show();
}
});
}
});
The isafter is working, but I can't figure out how to implement a function which is the opposite (would be nice if there was a isNotAfter jQuery function).
I have also tried instead of the second if statement:
else {
console.log(".view-content is not after, show message");
$('.pilots-result-message').show();
}

There is no method called isAfter(), you can check whether the next element of #quicktabs-tabpage-107_display-0 .view-filters is the current(this) element like
if ($('body').hasClass('page-pilots')) {
$.fn.isAfter = function (sel) {
return this.prevAll(sel).length !== 0;
}
$('#quicktabs-tabpage-107_display-0 .view-content').each(function () {
if ($("#quicktabs-tabpage-107_display-0 .view-filters").next().is(this)) {
console.log(".view-content is after, hide message");
$('.pilots-result-message').hide();
} else {
console.log(".view-content is not after, show message");
$('.pilots-result-message').show();
}
});
}

timer doesn't stop on buttonclick

I have trouble with timer in button click. When i click button startpause() method is called there i set start timer and stop timer. It works fine when I click button normally(one click after sometime another click) but when I click the button again and again speedly the timer starts to jump with 2-3 secs. Seems like more than one timer is running.. Anyone have any idea....?? here time is my timer method
function startpause() {
if(FLAG_CLICK) {
setTimeout(tim,1000);
FLAG_CLICK = false;
}
else {
clearTimeout(ti);
FLAG_CLICK = true;
}
}
function tim() {
time.innerHTML = t;
t = t + 1;
ti= setTimeout("tim()", 1000);
}

Try this:
// assuming you declared ti and t out here, cuz I hope they're not global
var t = 0;
var ti;
var running = false;
function startpause() {
clearTimeout(ti);
if(!running) {
ti = setTimeout(tim,1000);
running = true;
} else {
running = false;
}
}
function tim() {
time.innerHTML = t;
t = t + 1;
ti = setTimeout(tim,1000);
}
You can read more about the .setTimeout() here: https://developer.mozilla.org/en/docs/DOM/window.setTimeout
Also, see the jsfiddle I just created: http://jsfiddle.net/4BMhd/

You need to store setTimeout somewhere in order to manipulate it later.
var myVar;
function myFunction()
{
myVar=setTimeout(function(){alert("Hello")},3000);
}
function myStopFunction()
{
clearTimeout(myVar);
}
ref http://www.w3schools.com/js/js_timing.asp

Maybe you must change this:
if(FLAG_CLICK) {
setTimeout(tim,1000);
FLAG_CLICK = false;
}
to:
if(FLAG_CLICK) {
tim();
FLAG_CLICK = false;
}
It seems works for me normally
