Add new task
May be somebody can help me out ore give some advice how to solve this problem!
Sorry for my english and if my question is to badly explained!
var toDoList = function() {
var addNewTask = function() {
var input = document.getElementById("taks-input").value,
itemTexts = input,
colA = document.getElementById('task-col-a').children.length,
colB = document.getElementById('task-col-b').children.length,
taskBoks = document.createElement("div"),
work = document.getElementById("work"),
Category = "color-2",
taskCount = 1;
if (work.onclick === true) {
var Category = "color";
}
taskBoks.className = "min-box";
taskBoks.innerHTML = '<div class="col-3 chack" id="task_' + (taskCount++) + '"><i class="fa fa-star"></i></div><div class="col-8 task-text" id="taskContent"><p>' + itemTexts + '</p><span id="time-now"></span></div><div class="col-1 ' + (Category) + '"></div>'
if (colB < colA) {
var todolist = document.getElementById("task-col-b");
} else {
var todolist = document.getElementById("task-col-a");
}
//todolist.appendChild(taskBoks);
todolist.insertBefore(taskBoks, todolist.childNodes[0]);
},
addButton = function() {
var btn2 = document.getElementById("add-task-box");
btn2.onclick = addNewTask;
};
addButton()
}
toDoList();

you need to bind click event to your buttons and store that value in Category, so in you js add this
var toDoList = function() {
// set to default
var Category = "color-3";
// attach event to buttons
var catButtons = document.getElementsByClassName("catBtn");
// assign value based on event
var myCatEventFunc = function() {
var attribute = this.getAttribute("id");
if (attribute === 'work') {
Category = 'color';
} else if (attribute === 'home') {
Category = 'color-2';
}
};
for (var i = 0; i < catButtons.length; i++) {
catButtons[i].addEventListener('click', myCatEventFunc, false);
}
Demo: Fiddle
and remove this code from addNewTask function
if (work.onclick === true) {
var Category = "color";
}
It is a bit hard to understand what you are doing, what you are going for (a module of some kind?). You were not that far away from a working state.

I'm new to OOP and I'm struggling.
I'm building a library where you can add a book with the title, author nr of pages and if you've read it or not. When I add the first book if I check the box it displays that to book is not read(which is false). When I add a new book the read functionality is not applied to that book at all. I have no idea how to fix it
In this function you are checking the status if isRead which is incorrect.
Do this
Call the readStatus function inside the for loop
Pass the current parameter readStatus(myLibrary[i].checked)
Modify readStatus as shown below
function readStatus(status) {
const bookReadStatus = document.querySelector(".book__read");
if (status) {
bookReadStatus.classList.add("yes");
bookReadStatus.textContent = "I read it";
bookReadStatus.style.color = "rgb(110, 176, 120)";
} else {
bookReadStatus.classList.add("no");
bookReadStatus.textContent = "I have not read it";
bookReadStatus.style.color = "rgb(194, 89, 89)";
}
}
By clicking button all values are showing properly but when I use key event i.e ENTER Key on textarea to send the data then it's not showing the data. I have tried below code but it's just showing empty div. here is the jsfiddle Link
var messages = document.getElementById("messages");
var textbox = document.getElementById("textbox");
var button = document.getElementById("button");
$(document).ready(function() {
$("#textbox").emojioneArea({
pickerPosition: "top",
events: {
keyup: function(editor, event) {
if (event.which == 13) {
if (event.shiftKey) {
// With shift
} else {
event.preventDefault();
$('#button').click();
}
}
}
}
});
});
button.addEventListener("click", function(event) {
var newMessage = document.createElement("div");
newMessage.setAttribute('class', 'list');
newMessage.innerHTML = textbox.value;
messages.appendChild(newMessage);
textbox.value = "";
});
.wrap {
width: 300px;
margin: 0 auto;
}
.chat-area {

Since you are using emojioneArea you should use getText() and setText() methods which comes with emojioneArea library.
Here is a fiddle: https://jsfiddle.net/2vdeLgph/
function sendMessage() {
var newMessage = document.createElement("div");
newMessage.setAttribute('class', 'list');
newMessage.innerHTML = $('#textbox').data("emojioneArea").getText().trim();
messages.appendChild(newMessage);
$('#textbox').data("emojioneArea").setText('');
}
I am trying to learn by creating a chat bar. I have created a side nav bar with users and once I click the chat pop up box will open at the bottom. I want to add input field to that chatbox.
I tried to add the input field but I just got half success; it just gets added to the body not at the bottom of the chat box.

It is always better to try out your layout in plain html before testing with js
The following code initially loads more content when the bottom button is clicked but I need it to work when the scroll reach the bottom of the page... I've tried the code under the words //HERE IS THE PROBLEM// but it seems not to work.... any idea?
var lazyload = lazyload || {};
(function($, lazyload) {
"use strict";
var page = 2,
buttonId = "#button-more",
loadingId = "#loading-div",
container = "#container";
//HERE IS THE PROBLEM
$(window).scroll(function() {
if($(window).scrollTop() + $(window).height() == $(document).height()) {
lazyload.load = function() {
var url = "./" + page + ".html";
$(buttonId).hide();
$(loadingId).show();
$.ajax({
url: url,
success: function(response) {
if (!response || response.trim() == "NONE") {
$(buttonId).fadeOut();
$(loadingId).text("No more entries to load!");
return;
}
appendContests(response);
},
error: function(response) {
$(loadingId).text("Sorry, there was some error with the request. Please refresh the page.");
}
});
};
}
});
var appendContests = function(response) {
var id = $(buttonId);
$(buttonId).show();
$(loadingId).hide();
$(response).appendTo($(container));
page += 1;
};
})(jQuery, lazyload);

Please Help!
Thanks.
I may suggest you to use the jQuery dialog plugin (dialog), plus jsPDF in order to produce a dialog on a print button containing a pdf version of the html related to your selected seat.
The result is like:
The snippet is:
var price = 120; //price
var sc;
//sum total money
function recalculateTotal(sc) {
var total = 0;
sc.find('selected').each(function () {
total += price;
});
return total;
}
$(function () {
var $cart = $('#selected-seats'), //Sitting Area
$counter = $('#counter'), //Votes
$total = $('#total'); //Total money
sc = $('#seat-map').seatCharts({
map: [ //Seating chart
'aaaaaaaaaa',
'aaaaaaaaaa',
'aaaaaaaaaa',
'aaaaaaaaaa',
'aaaaaaaaaa',
'aaaaaaaaaa',
'aaaaaaaaaa',
'aaaaaaaaaa',
'aaaaaaaaaa',
],
naming: {
top: false,
getLabel: function (character, row, column) {
return column;
}
},
legend: { //Definition legend
node: $('#legend'),
items: [
['a', 'available', 'Avail'],
['a', 'unavailable', 'Sold']
]
},
click: function () { //Click event
if (this.status() == 'available') { //optional seat
$('<li>R' + (this.settings.row + 1) + ' S' + this.settings.label + '</li>')
.attr('id', 'cart-item-' + this.settings.id)
.data('seatId', this.settings.id)
.appendTo($cart);
$counter.text(sc.find('selected').length + 1);
$total.text(recalculateTotal(sc) + price);
return 'selected';
} else if (this.status() == 'selected') { //Checked
//Update Number
$counter.text(sc.find('selected').length - 1);
//update totalnum
$total.text(recalculateTotal(sc) - price);
//Delete reservation
$('#cart-item-' + this.settings.id).remove();
//optional
return 'available';
} else if (this.status() == 'unavailable') { //sold
return 'unavailable';
} else {
return this.style();
}
}
});
//sold seat
sc.get(['1_2', '4_4', '4_5', '6_6', '6_7', '8_5', '8_6', '8_7', '8_8', '10_1', '10_2']).status('unavailable');

The function to print in the html with jquery is "html()" for example if you want to write in the div with the id legend you can do this:
$("#legend").html("<p>whatever you want to write</p>");
