Can't use stream in onclick callback

const ToneStream = require('tone-stream')
const Speaker = require('speaker');
const blessed = require('blessed');
const format = {
sampleRate: 8000,
bitDepth: 16,
channels: 1
}
let stream = new ToneStream(format);
const speaker = new Speaker(format);
stream.pipe(speaker);
var screen = blessed.screen({
smartCSR: true
});
let boxarray = [];
for(let i = 0; i < 10; i++) {
let box = blessed.box({
top: "0%",
left: (i/10 *100).toString() + '%',
width: (1/11 *100).toString() + '%',
height: "100%",
tags: true,
style: {
bg: "white"
}
});
box.on('click', () => {
stream.add([4000, 440]);
console.log(i);
});
boxarray.push(box);
}
boxarray.forEach((box) => {
screen.append(box);
});
screen.key(['escape', 'q', 'C-c'], function(ch, key) {
return process.exit(0);
});
screen.render();
I'm trying to get a tone to play when each UI box is clicked. My onclick event added to the boxes isn't working. The console.log works but no tone is played. How can I get a tone to play when a ui box is clicked? The reference to stream still exists, I can console log it without receiving null. The stream is also still open.

Measures for the code that prevents iFrame execution

I want to implement iFrames, but this pagination code gets in the way.
If I don't comment out this pagination code, iFrame will not be executed.
pagination code ( pagination.js ):
////////// this part or ↓
function tpl(data) {
var html = '';
$.each(data, function(index,item) {
html += '<section class="item">' + item + '</section>';
});
return html;
}
//////////
$(function() {
var len = $('.item').length;
$('#no-p').pagination({
dataSource: function(done) {
var result = [];
for (var i = 0; i < len; i++) {
var $item = $('.item').get(i);
if ($item) result.push($item.innerHTML);
}
done(result);
},
pageSize: 8,
showPageNumbers: false,
showNavigator: true,
autoHidePrevious: true,
autoHideNext: true,
////////// iFrame will not be executed unless this part is deleted ↓
callback: function(data,pagination) {
var html = tpl(data);
$('#items').html(html);
}
//////////
});
});
iFrame code ( iziModal.js ):
$(document).on('click', '.item1', function (event) {
$(".item1").click(function (event) {
event.preventDefault();
$('#iframe').iziModal('open');
$('#modal').iziModal('open', {
iframeURL: $(this).data('href')
});
});
$("#modal").iziModal({
iframe: true,
width: '98%',
iframeHeight: 650,
zindex: '110',
iframeURL: "data.html",
group: 'works',
overlayColor: 'rgba(0,0,0,0.1)'
});
$(".item1").off('click');
});
However, I need both iFrame and pagination.
How can I implement both?

Showing Progress while Child row loads

Coming again with another question :)
This time I had a requirement to show some progress while Child rows are being loaded. Since there is an Api call which relatively takes little time to return data, I do want to show the some progress unless the user who clicks the parent row is totally unaware whether there is a call done to see its child rows.
What I have done:
I wrote a style sheet class which has a
loader-small.gif
image as this:
tr.loading td.details-control {
background: url('/Images/loader-small.gif') no-repeat center center;
}
and applied like this:
$('#accountManagerEarningsDataTable tbody').on('click', 'td.details-control', function () {
var tr = $(this).closest('tr');
var row = table.row(tr);
try {
if (row.child.isShown()) {
// This row is already open - close it
row.child.hide();
tr.removeClass('shown');
}
else {
//Calling the loading Class ------>
tr.addClass('loading');
// Open this row
var arrForTable1 = [];
var arrForTable2 = [];
totalBrokerage = 0;
totalRetailBrokerage = 0;
totalSelfServiceBrokerage = 0;
console.log('You selected: ' + row.data().AccountManagerID);
var settings = {
"columnDefs": [
{ targets: 1, align: "right", decimals: 0 },
{ targets: 2, align: "right", decimals: 0 },
{ targets: 3, align: "right", decimals: 0 },
{ targets: 4, align: "right", decimals: 2 },
{ targets: 5, align: "right", decimals: 2 }
]
};
//problems with asynchoronus call back
var response = organization_GetAccountManagerDetailEarningsAccountData(row.data(), purl2, pcontext);
if (response.success === "true") {
for (var i = 0; i < response.value.length; i++) {
for (var j = 0; j < response.value[i].Securities.length; j++) {
var itemRow2 = {};
itemRow2["Security ID"] = response.value[i].Securities[j].SecurityId;
itemRow2["Trades"] = response.value[i].Securities[j].Trades;
itemRow2["Buy Qty"] = response.value[i].Securities[j].BuyQuantity;
itemRow2["Sell Qty"] = response.value[i].Securities[j].SellQuantity;
itemRow2["Total Brkg"] = response.value[i].Securities[j].Effective_Brokerage;
itemRow2["Online Brkg"] = response.value[i].Securities[j].Online_Brokerage;
arrForTable2.push(itemRow2);
totalBrokerage = totalBrokerage + parseFloat(response.value[i].Securities[j].Effective_Brokerage);
totalSelfServiceBrokerage = totalSelfServiceBrokerage + parseFloat(response.value[i].Securities[j].Online_Brokerage);
}
totalBrokerage = Math.round(totalBrokerage * 100) / 100;
totalSelfServiceBrokerage = Math.round(totalSelfServiceBrokerage * 100) / 100;
totalRetailBrokerage = Math.round(totalRetailBrokerage * 100) / 100;
var itemRow1 = {};
itemRow1["Account ID"] = response.value[i].AccountId;
itemRow1["Account Name"] = response.value[i].AccountName;
itemRow1["..."] = '<div class="alert alert-info" role="alert">' + buildHtmlTable(arrForTable2, 'table2x' + j, settings) + '<p>Total Brokerage ' + numberWithCommas(totalBrokerage) + '</p></div>';
arrForTable1.push(itemRow1);
arrForTable2 = [];
totalBrokerage = 0;
totalRetailBrokerage = 0;
totalSelfServiceBrokerage = 0;
}
tr.removeClass('loading');
htmlTable1 = buildHtmlTable(arrForTable1, 'table1x' + i);
row.child(htmlTable1).show();
tr.addClass('shown');
}
else {
row.child('<table><tr><td>' + response.value[0].AccountId + '</td></tr></table>').show();
tr.addClass('shown');
};
}
} catch (e) {
console.log(e.message);
}
});
The Problem:
Firefox nicely shows the Progress image after the user clicks it, but Edge and Chrome does not show. Both browsers crossed this piece of code when I was debugging from developer tools of the respective browser.
Its browser compatible problem? Is there a solution for it? Help me please.

In case of chrome there is such an issue while showing the loading bar while making a server call. Please make the following changes where you are making the service call. First add the class loading to the table
tr.addClass('loading');
After that make the service call by giving a timeout function
setTimeout(function(){
var response = organization_GetAccountManagerDetailEarningsAccountData(row.data(), purl2, pcontext);
......
//Your service calls and response call backs
},1);
On providing a timeout (say 1ms), Chrome will get the time to bind the loading bar to DOM, In other case the DOM Object is not available to show the spinner.

CasperJS viewport & viewportSize not resizing browser

Is anyone having any issues lately with the CasperJS or PhantomJS viewport or viewportSize?
I've tried using
page.viewportSize = {width: 1280, height: 1024};
casper.start()
.viewport(800, 600);
casper.options.viewportSize = {width: 1290, height: 1024};
No matter where I put them in the code the browser size still stays the default 300, 400.
/*jshint strict:false*/
/*global CasperError, console, phantom, require*/
var links = [];
var casper = require("casper").create();
var w = window.innerWidth;
var h = window.innerHeight;
function getLinks() {
var links = document.querySelectorAll("h3.r a");
return Array.prototype.map.call(links, function(e) {
try {
// google handles redirects hrefs to some script of theirs
return (/url\?q=(.*)&sa=U/).exec(e.getAttribute("href"))[1];
} catch (err) {
return e.getAttribute("href");
}
});
}
casper.options.viewportSize = {width: 1600, height: 950};
casper.start("http://google.fr/", function() {
// search for 'casperjs' from google form
this.viewport(900, 800);
this.fill('form[action="/search"]', { q: "casperjs" }, true);
});
casper.then(function() {
// aggregate results for the 'casperjs' search
links = this.evaluate(getLinks);
// now search for 'phantomjs' by fillin the form again
this.fill('form[action="/search"]', { q: "phantomjs" }, true);
});
casper.then(function() {
// aggregate results for the 'phantomjs' search
links = links.concat(this.evaluate(getLinks));
});
console.log("Height==> " + h);
console.log("Width==> " + w);
casper.run(function() {
// echo results in some pretty fashion
this.echo(links.length + " links found:");
this.echo(" - " + links.join("\n - "));
this.exit();
});

Script doesn't work on elements loaded with infinite scrolling

I'm using this script on my tumblr page, which gives posts different random text colors:
function get_random_color() {
var letters = '0123456789ABCDEF'.split('');
var color = '#';
for (var i = 0; i < 6; i++ ) {
color += letters[Math.round(Math.random() * 15)];
}
return color;}
$(function() {
$(".post").each(function() {
$(this).css("color", get_random_color());
}); });
The thing is the script isn't working for elements loaded with infinite scrolling. Can anyone help me rewrite this code? I don't know how to write javascript sadly.

Take a look at your blog's main.js script. You can call your custom function when you grab the new elements from another page. This is my proposed revision of your main.js file.
$(window).load(function () {
var $wall = $('#content');
$wall.imagesLoaded(function () {
$wall.masonry({
itemSelector: '.post',
isAnimated: false
});
});
$wall.infinitescroll({
navSelector: '#pagination',
nextSelector: '#pagination li a.pagination_nextlink',
itemSelector: '.post',
loadingImg: "http://static.tumblr.com/kwz90l7/bIdlst7ub/transparent.png",
loadingText: " ",
donetext: " ",
bufferPx: 100,
debug: false,
errorCallback: function () {
$('#infscr-loading').animate({
opacity: .8
}, 2000).fadeOut('normal');
}
}, function (newElements) {
var $newElems = $(newElements);
$newElems.hide();
$newElems.each(function(value){
value.css("color", get_random_color());
});
$newElems.imagesLoaded(function () {
$wall.masonry('appended', $newElems, {
isAnimated: false,
animationOptions: {
duration: 900,
easing: 'linear',
queue: false
}
}, function () {
$newElems.fadeIn('slow');
});
});
$(document).ready(function () {
$("a[rel^='prettyPhoto']").prettyPhoto({
deeplinking: false,
default_width: 600,
default_height: 550,
allow_resize: true,
});
});
});
$('#content').show(500);
});
function get_random_color() {
var letters = '0123456789ABCDEF'.split('');
var color = '#';
for (var i = 0; i < 6; i++ ) {
color += letters[Math.round(Math.random() * 15)];
}
return color;
}
What I've done is add your get_random_color function and called it from within the Infinite Scroll call to add a custom color to each of the elements in $newElems so really, all I've done is taken your code and integrated it differently than what you were trying to do, which wasn't working. This should, theoretically, work. If it doesn't or you have questions, let me know.
