'DOMException: Failed to execute 'querySelectorAll' on 'Element' when using an 'option:selected' selector

I'm running a page which throws an error at the following line:

Here is the exception that I see in debug mode:
From what I understand from Failed to execute 'querySelectorAll' on 'Element' in ExtJS 5, :selected is not part of the CSS specification.
How should I fix this? Should I use:
var label = $select.find('option').filter(':selected').html() || $select.find('option').filter(':first').html() || "";
?

Converting Phil's comment to an answer, my debugger was set to pause on all exceptions (including caught ones). I had to de-activate the 'stop sign' button shown below to make the debugger work normally again.

CasperJS - Memory Exhausted

When I run this through command line, it goes for an hour or two, and then command line spits out "Memory Exhausted". I can't figure out what's going on.

Due to a bug:
https://bugs.webkit.org/show_bug.cgi?id=154452
Resolved by turning off image loading.
EDIT: seems to still be a problem. My guess is that it's because casperjs is outdated, so I'm abandoning it and using python.

Js & Jquery:Understanding a search code with JSON request

i have a js search in my page that i don't get perfectly how does work because i don't know 100% js and jquery. As far as i think the code takes the input and search match with a link to a database that returns a JSON value depending on what name you put on the link (?name="the-input-name-here"), then, the code parse the json and determinates if the name of the input it's a valid surname and if it is the check if it has a running page, if it has redirects you to that page. If the input is a valid surname but doesn't have a running page it redirects you to "landing-page-yes.html". If the input isn't a valid surname it redirects you to "landing-page-no.html".
I need help to understand how the code does this in order to make a simplify version. How that call to another url database is parsed by the js ? How can i think something similar with a backend and ajax ? I need to understand 100% what this code does and i'm kinda lost.
THANKS !

Auto refresh a div containing Twitter posts

I am working with Twitter APIv1.1 and currently I am trying to implement a box which will display my latest tweets. This can be seen here:
http://www.jdiadt.com/twitterv1_1feed/testindex.html
However I would like to make this so that when I tweet, the box is automatically updated. I am quite new to JQuery and Javascript so I would appreciate any advice on how I can do this. I've hear AJAX can be used for something like this. Currently I have to refresh the entire page to display any new tweets. I'd like to only refresh the box.
Here is my script: twitterfeed.js
$(document).ready(function () {
var displaylimit = 10;
var twitterprofile = "jackcoldrick";
var screenname = "Jack Coldrick";
var showdirecttweets = false;
var showretweets = true;
var showtweetlinks = true;
var showprofilepic = true;

var loadingHTML = '';
headerHTML += '<a href="https://twitter.com/" ><img src="http://www.jdiadt.com/twitterv1_1feed/twitteroauth/images/birdlight.png" width="34" style="float:left;padding:3px 12px 0px 6px" alt="twitter bird" /></a>';
headerHTML += '<h1>'+screenname+' <span style="font-size:13px"><a href="https://twitter.com/'+twitterprofile+'" >#'+twitterprofile+'</a></span></h1>';
loadingHTML += '<div id="loading-container"><img src="http://www.jdiadt.com/twitterv1_1feed/twitteroauth/images/ajax-loader.gif" width="32" height="32" alt="tweet loader" /></div>';

This is the get_tweets.php script where I encode the results in a JSON format.
<?php
session_start();
require_once('twitteroauth/twitteroauth/twitteroauth.php');
$twitteruser = "jackcoldrick";
$notweets = 30;
$consumerkey="xxxxxxxxxxxxxx";
$consumersecret="xxxxxxxxxxxxxxx";
$accesstoken="xxxxxxxxx";
$accesstokensecret="xxxxxxxxxxxxxx";
function getConnectionWithAccessToken($cons_key, $cons_secret, $oauth_token, $oauth_token_secret){
$connection = new TwitterOAuth($cons_key, $cons_secret, $oauth_token, $oauth_token_secret);
return $connection;
}
$connection = getConnectionWithAccessToken($consumerkey, $consumersecret, $accesstoken, $accesstokensecret);
$tweets = $connection->get("https://api.twitter.com/1.1/statuses/user_timeline.json?screen_name=".$twitteruser."&count=".$notweets);
echo json_encode($tweets);
?>

This seems doable with your current code. Things to consider:
I'm not sure, but Twitter might have a limit on requests (I imagine it's not a huge one)
Just encapsulate the reusable parts of your code in a function called updateTweets, and call that with a setInterval. There isn't anyway to really "push" tweet updates to your JavaScript, that I know of.

I would put your update code into a function that has a SetTimeout() that does a recursive call to the new function every x seconds. An example below.
$(document).ready(function () {
// Call to your update twitter function
updateTwitter(data);
});
function updateTwitter(data) {
// do your original update twitter GET
$.getJSON('http://www.jdiadt.com/twitterv1_1feed/get_tweets.php', function () {
//... all that code
});
// Sets a timer that calls the updateTwitter function 1x a minute
setTimeout(function () { updateTwitter(data); }, 60000);
}

Having issues with live calculations, calculating each key stroke

I have a table that calculates a total depending on the input the user types. My problem is that the jquery code is calculating each key stroke and not "grabbing" the entire number once you stop typing. Code is below, any help woud be greatly appreciated.
$(document).ready(function() {
$('input.refreshButton').bind('click', EstimateTotal);
$('input.seatNumber').bind('keypress', EstimateTotal);
$('input.seatNumber').bind('change', EstimateTotal);
});
//$('input[type=submit]').live('click', function() {
function EstimateTotal(event) {
var tierSelected = $(this).attr('data-year');
var numberSeats = Math.floor($('#numberSeats_' + tierSelected).val());
$('.alertbox_error_' + tierSelected).hide();
if (isNaN(numberSeats) || numberSeats == 0) {
$('.alertbox_error_' + tierSelected).show();
} else {
$('.alertbox_error_' + tierSelected).hide();
var seatHigh = 0;
var seatLow = 0;
var seatBase = 0;
var yearTotal = 0;
var totalsArray = [];
var currentYear = 0;
$('.tier_' + tierSelected).each(function() {
seatLow = $(this).attr('data-seat_low');
firstSeatLow = $(this).attr('data-first_seat_low');
seatHigh = $(this).attr('data-seat_high');
seatBase = $(this).attr('data-base_cost');
costPerSeat = $(this).attr('data-cost_per_seat');
years = $(this).attr('data-year');
seats = 0;
if (years != currentYear) {
if (currentYear > 0) {
totalsArray[currentYear] = yearTotal;
}
currentYear = years;
yearTotal = 0;
}
if (numberSeats >= seatHigh) {
seats = Math.floor(seatHigh - seatLow + 1);
} else if (numberSeats >= seatLow) {
seats = Math.floor(numberSeats - seatLow + 1);
}
if (seats < 0) {
seats = 0;
}
yearTotal += Math.floor(costPerSeat) * Math.floor(seats) * Math.floor(years) + Math.floor(seatBase);
});
totalsArray[currentYear] = yearTotal;
totalsArray.forEach(function(item, key) {
if (item > 1000000) {
$('.totalCost_' + tierSelected + '[data-year="' + key + '"]').append('Contact Us');
} else {
$('.totalCost_' + tierSelected + '[data-year="' + key + '"]').append('$' + item);
}
});
}
}

You'll need a setTimeout, and a way to kill/reset it on the keypress.
I'd personally do something like this:
var calc_delay;
$(document).ready(function() {
$('input.refreshButton').bind('click', runEstimateTotal);
$('input.seatNumber').bind('keypress', runEstimateTotal);
$('input.seatNumber').bind('change', runEstimateTotal);
});
function runEstimateTotal(){
clearTimeout(calc_delay);
calc_delay = setTimeout(function(){ EstimateTotal(); }, 100);
}
function EstimateTotal() {
....
What this does is prompt the system to calculate 100ms after every keypress - unless another event is detected (i.e. runEstimateTotal is called), in which case the delay countdown resets.
