Microsoft Azure Text to Speech - Stop Recording On Button Press - StopRecognitionOnceAsync() Not Working?

Apologies in advance for any terminology mistakes, I'm a student and trying my hardest to be as clear as possible! and thanks in advance for any help!
I'm trying to use Azure Speech-To-Text services. I'd like the user to be able to press a start and stop button to record themselves and print out the transcription. My app will eventually be a React Frontend and Rails backend, but right now I am just trying to understand and work through the demo.
I'm confused by the documentation but was able to get things half working. However, right now it just continuously listens to the speaker and never stops.
I want to use stopContinuousRecognitionAsync() or recognizer.close() once a button is pressed, but I cannot seem to get it working. The farthest I've gotten is the result is logged only once the stop button is pressed, but it continues to listen and print out results. I've also tried using recognizer.close() -> recognizer = undefined but to no avail. I am guessing that due to the asynchronous behavior, it closes out the recognizer before logging a result.
The latest code I've tried is below. This result starts listening on start click and prints speech on stop, but continues to listen and log results.
// subscription key and region for speech services.
var subscriptionKey, serviceRegion;
var authorizationToken;
var SpeechSDK;
var recognizer;
document.addEventListener("DOMContentLoaded", function () {
startRecognizeOnceAsyncButton = document.getElementById("startRecognizeOnceAsyncButton");
subscriptionKey = document.getElementById("subscriptionKey");
serviceRegion = document.getElementById("serviceRegion");
phraseDiv = document.getElementById("phraseDiv");
startRecognizeOnceAsyncButton.addEventListener("click", function () {
startRecognizeOnceAsyncButton.disabled = true;
phraseDiv.innerHTML = "";
// if we got an authorization token, use the token. Otherwise use the provided subscription key
var speechConfig;
if (authorizationToken) {
speechConfig = SpeechSDK.SpeechConfig.fromAuthorizationToken(authorizationToken, serviceRegion.value);
} else {
speechConfig = SpeechSDK.SpeechConfig.fromSubscription(“API_KEY”, serviceRegion.value);
}
speechConfig.speechRecognitionLanguage = "en-US";
var audioConfig = SpeechSDK.AudioConfig.fromDefaultMicrophoneInput();
recognizer = new SpeechSDK.SpeechRecognizer(speechConfig, audioConfig);
recognizer.startContinuousRecognitionAsync(function () {}, function (err) {
console.trace("err - " + err);});
stopButton = document.querySelector(".stopButton")
stopButton.addEventListener("click", () =>{
console.log("clicked")
recognizer.recognized = function(s,e) {
console.log("recognized text", e.result.text)
}
})
});

Assuming the recognizer is conjured correctly outside of the code, there's a few things to change to get the result you want.
The events should be hooked to the recognizer before calling startContinuousRecognition().
In the stop button handler, call stop. I'd also hook the stop event outside of the start button click handler.
Quick typed changes, didn't compile. :-)
startRecognizeOnceAsyncButton.addEventListener("click", function () {
startRecognizeOnceAsyncButton.disabled = true;
//div where text is being shown
phraseDiv.innerHTML = "";
// The event recognized signals that a final recognition result is received.
recognizer.recognized = function(s,e) {
console.log("recognized text", e.result.text)
}
//start listening to speaker
recognizer.startContinuousRecognitionAsync(function () {}, function (err) {
console.trace("err - " + err);});
});
stopButton = document.querySelector(".stopButton")
stopButton.addEventListener("click", () =>{
console.log("clicked");
recognizer.stopContinuousRecongition();
};

JQuery $.post callback firing a function that never finishes

Here's the problem. I'm making a callback to the server that receives an MVC partial page. It's been working great, it calls the success function and all that. However, I'm calling a function after which iterates through specific elements:
$(".tool-fields.in div.collapse, .common-fields div.collapse").each(...)
Inside this, I'm checking for a specific attribute (custom one using data-) which is also working great; however; the iterator never finishes. No error messages are given, the program doesn't hold up. It just quits.
Here's the function with the iterator
function HideShow() {
$(".tool-fields.in div.collapse, .common-fields div.collapse").each(function () {
if (IsDataYesNoHide(this)) {
$(this).collapse("show");
}
else
$(this).collapse("hide");
});
alert("test");
}
Here's the function called in that, "IsDataYesNoHide":
function IsDataYesNoHide(element) {
var $element = $(element);
var datayesnohide = $element.attr("data-yes-no-hide");
if (datayesnohide !== undefined) {
var array = datayesnohide.split(";");
var returnAnswer = true;
for (var i in array) {
var answer = array[i].split("=")[1];
returnAnswer = returnAnswer && (answer.toLowerCase() === "true");
}
return returnAnswer;
}
else {
return false;
}
}
This is the way the attribute appears
data-yes-no-hide="pKanban_Val=true;pTwoBoxSystem_Val=true;"
EDIT: Per request, here is the jquery $.post
$.post(path + conPath + '/GrabDetails', $.param({ data: dataArr }, true), function (data) {
ToggleLoader(false); //Page load finished so the spinner should stop
if (data !== "") { //if we got anything back of if there wasn't a ghost record
$container.find(".container").first().append(data); //add the content
var $changes = $("#Changes"); //grab the changes
var $details = $("#details"); //grab the current
SplitPage($container, $details, $changes); //Just CSS changes
MoveApproveReject($changes); //Moves buttons to the left of the screen
MarkAsDifferent($changes, $details) //Adds the data- attribute and colors differences
}
else {
$(".Details .modal-content").removeClass("extra-wide"); //Normal page
$(".Details input[type=radio]").each(function () {
CheckOptionalFields(this);
});
}
HideShow(); //Hide or show fields by business logic
});
For a while, I thought the jquery collapse was breaking, but putting the simple alert('test') showed me what was happening. It just was never finishing.
Are there specific lengths of time a callback function can be called from a jquery postback? I'm loading everything in modal views which would indicate "oh maybe jquery is included twice", but I've already had that problem for other things and have made sure that it only ever includes once. As in the include is only once in the entire app and the layout is only applied to the main page.
I'm open to any possibilities.
Thanks!

Found the problem. I had a variable that was sometimes being set as undefined cause it to silently crash. I have no idea why there was no error message.

Meteor: oncreated vs onrendered

The dilemma:
oncreated: the template is not yet rendered (fires only one
time for each template).
onrendered: the template is rendered (fires multiple times).
Is it possible to fire a function only once the template is rendered fully?
I have a list of messages, that look similar to this
<template name="messages">
<div id="messages">
<span class="message">{{this.message}}</span>
</div>
</template>
Each time a new message is inserted into the DOM, I want to know if the text of the message contains the username.
The following code snippet runs multiple times, of which it should only run a single time.
Template.messages.rendered = function() {
var username = Meteor.user().services.twitter.screenName;
$("#messages").bind("DOMSubtreeModified", function() {
var lastmessage = $('.message').last().text();
if (lastmessage.indexOf(username) > -1) {
//Do something
}
}
}
Interchanging rendered by created & changing the template to contain a single message, makes the function run one time for each new message. This means it takes the second to last value for the lastmessage variable:
Template.message.created = function() {
var username = Meteor.user().services.twitter.screenName;
var lastmessage = $('.message').last().text();//this is not the last message
if (lastmessage.indexOf(username) > -1) {
//Do something
}
}

Honestly couldn't you do something like this in "rendered". Or you could put in some callback after you render your extra stuff into the DOM.
Additionally you could use self.autorun(() => { if(self.alreadyRun) return; ... }) and self.alreadyRun = new ReactiveVar(false).
Just guessing!
var self = this;
self.alreadyRun = false;
if(self.alreadyRun){
self.alreadyRun = true;
// run once code here
}

Fixed this by wrapping the code in a setTimeout function.

Ubuntu HTML5 App: Change Tab on JS command

First Question here, too! Yay! Just moved this from AskUbuntu.
I am just about to finish a little private project for gaining some experience where i try to change the app layout so it works as a normal website (on Jimdo, so it was quite of a challenge first) without much JavaScript required but is fully functional on mobile view.
Since Jimdo serves naturally only the actual site, I had to implement an
if (activeTab.getAttribute('jimdo-target') != null)
location.href = activeTab.getAttribute('jimdo-target');
redirect into the __doSelectTab() function in tabs.js . (In js I took the values from the jimdo menu string to build the TABS menu with this link attribute)
Now everything works fine exept at page load the first tab is selected. I got it to set the .active and .inactive classes right easily, but it is not shifted to the left.
So my next idea is to let it initialize as always and then send a command to change to the current tab.
Do you have any idea how to manage this? I couldn't because of the this.thisandthat element I apparently don't really understand...
Most of you answering have the toolkit and the whole code, but I am listing the select function part of the tabs.js:
__doSelectTab: function(tabElement, forcedSelection) {
if ( ! tabElement)
return;
if (tabElement.getAttribute("data-role") !== 'tabitem')
return;
if (forcedSelection ||
(Array.prototype.slice.call(tabElement.classList)).indexOf('inactive') > -1) {
window.clearTimeout(t2);
activeTab = this._tabs.querySelector('[data-role="tabitem"].active');
offsetX = this.offsetLeft;
this._tabs.style['-webkit-transition-duration'] = '.3s';
this._tabs.style.webkitTransform = 'translate3d(-' + offsetX + 'px,0,0)';
this.__updateActiveTab(tabElement, activeTab);
if (activeTab.getAttribute('jimdo-target') != null)
location.href = activeTab.getAttribute('jimdo-target');
[].forEach.call(this._tabs.querySelectorAll('[data-role="tabitem"]:not(.active)'), function (e) {
e.classList.remove('inactive');
});
var targetPageId = tabElement.getAttribute('data-page');
this.activate(targetPageId);
this.__dispatchTabChangedEvent(targetPageId);
} else {
[].forEach.call(this._tabs.querySelectorAll('[data-role="tabitem"]:not(.active)'), function (el) {
el.classList.toggle('inactive');
});
var self = this;
t2 = window.setTimeout(function () {
var nonActiveTabs = self._tabs.querySelectorAll('[data-role="tabitem"]:not(.active)');
[].forEach.call(nonActiveTabs, function (el) {
el.classList.toggle('inactive');
});
}, 3000);
}
},
...and my app.js hasn't anything special:
var UI = new UbuntuUI();
document.addEventListener('deviceready', function() { console.log('device ready') }, true);
$(document).ready(function () {
recreate_jimdo_nav();
UI.init();
});

So meanwhile found a simple workaround, however I'd still like to know if there is another way. Eventually I noticed the __doSelectTab() function is the one that executes the click, so it does nothing but to show the other tab names when they are hidden first. so I added the global value
var jnavinitialized = false;
at the beginning of the tabs.js and run
var t = this;
setTimeout(function(){t.__doSelectTab(t._tabs.querySelector('[data-role="tabitem"].jnav-current'))}, 0);
setTimeout(function(){t.__doSelectTab(t._tabs.querySelector('[data-role="tabitem"].jnav-current'))}, 1);
setTimeout(function(){jnavinitialized = true;}, 10);
at the top of the __setupInitialTabVisibility() function. Then I changed the location.href command to
if (activeTab.getAttribute('jimdo-target') != null && jnavinitialized)
location.href = activeTab.getAttribute('jimdo-target');
And it works. But originally I searched for a way to change the tab on command, not to run the command for selecting twice. So if you know a better or cleaner way, you are welcome!

Validate context menu item for each tab

I am developing a simple Safari extension that adds a context menu item, which when clicked will let me perform a specific task with the data on the page current. In my injected-scripts.js I have a function validForContextMenu which determines wether or not the context menu should be displayed for the clicked tab. Along with this function I am dispatching the following message to my global.html in order to let it know if the tab should display my context menu item or not.
safari.self.tab.dispatchMessage("validate", validForContextMenu());
In global.html I am doing the following to listen to message, store the data returned by injected-scripts.js, and perform the actual validation:
var contextMenuDisabled = true;
function respondToMessage(theMessageEvent) {
if (theMessageEvent.name === "validate") {
contextMenuDisabled = theMessageEvent.message;
}
}
safari.application.activeBrowserWindow.activeTab.addEventListener("message", respondToMessage, false);
function validateCommand(event) {
event.target.disabled = contextMenuDisabled;
}
safari.application.addEventListener("validate", validateCommand, false);
This all works out quite fine apart from the fact that the validation is only performed once, and only for the tab/page being frontmost at the time my extension loads. If that page is valid for context menu, then so will all other pages and vice versa. I would like the validation to be performed individually for each of Safaris tabs.
Ca this be done? Am I missing something on the way injected scripts or dispatched messages works?

The global.html is singleton and therefore your have only one variable contextMenuDisabled for all tabs. Safari has the special API for this task - safari.self.tab.setContextMenuEventUserInfo.
I use the next code in my extension. In inject.js:
document.addEventListener('contextmenu', onContextMenu, false);
function onContextMenu(ev) {
var UserInfo = {
pageId: pageId
};
var sel = document.getSelection();
if (sel && !sel.isCollapsed)
UserInfo.isSel = true;
safari.self.tab.setContextMenuEventUserInfo(ev, UserInfo);
};
In global.js:
safari.application.addEventListener('validate', onValidate, false);
function onValidate(ev) {
switch (ev.command) {
case 'DownloadSel':
if (!ev.userInfo || !ev.userInfo.isSel)
ev.target.disabled = true;
break;
};
};
