Creating a drop-down menu in Javascript - Nothing showing on canvas - javascript

I'm attempting to create a drop-down menu in javascript, html and css however when I run the code nothing is showing on canvas. Is it because the files aren't communicating with each other correctly?
HTML:
<!DOCTYPE html>
<html>
<head>
<title>DropdownMenu</title>
<link rel='stylesheet' type='text/css' href='Stylesheetdropdown.css'/>
</head>
<body>
<canvas id="canvas" width="5000" height="5000">
</canvas>
<script type='text/javascript' src='DropdownMenu.js'></script>
</body>
<body>
<div class = "dropdown">
<button onclick = "dropdown()" class = "drpdwnbtn">Menu</button>
<div id = "myMenu" class = "drpdwncntnt">
<p>100</p>
<p>200</p>
<p>300</p>
</div>
</div>
</body>
</html>
Javascript:
function dropdown() {
document.getElementById("myMenu").classList.toggle("show");
}
window.onclick = function (event) {
if (!event.target.matches('.drpdwnbtn')) {
var dropdowns = document.getElementsByClassName("drpdwncntnt"),
i,
openDropdown = dropdowns[i];
for (i = 0; i < dropdowns.length; i += 1) {
if (openDropdown.classList.contains('show')) {
openDropdown.classList.remove('show');
}
}
}
};
CSS:
.drpdwnbtn {
background-color: #4CAF50;
color: white;
padding: 16px;
font-size: 16px;
border: none;
cursor: pointer;
}
.drpdwnbtn:hover, .drpdwnbtn:focus {
background-color: #E0FFFF;
}
.dropdown {
position: relative;
display: inline-block;
}
.drpdwncntnt {
display: none;
position: absolute;
background-color: #f9f9f9;
min-width: 160px;
overflow: auto;
box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.2);
z-index: 1;
}
.drpdwncntnt a {
color: black;
padding: 12px 16px;
text-decoration: none;
display: block;
}
.dropdown a:hover {background-color: #f1f1f1}
.show {display:block;}

Your canvas was over your menu div, your html should look like:
<div class = "dropdown">
<button onclick = "dropdown()" class = "drpdwnbtn">Menu</button>
<div id = "myMenu" class = "drpdwncntnt">
<p>100</p>
<p>200</p>
<p>300</p>
</div>
</div>
<canvas id="canvas" width="5000" height="5000">
</canvas>
, so here is a working fiddle:

when click on the one dropdown other dropdown will be close

I created a dropdown list Javascript Toggle method. I face a problem a problem. The problem is - After clicking one dropdown, another dropdown still opens. I want others dropdown Will to be closed when I click on dropdown. This happen will be each dropdown. How do I do it?
<html>
<head>
<style>
nav{
width:100%;
height:50px;
background-color:#000;
}
button{
height:50px;
margin-left: 10px;
border:0;
background-color: transparent;
color: #fff;
cursor: pointer;
}
div{
display: none;
width: 100%;
height: 300px;
position: absolute;
}
#myDIV1{
background-color: rgb(0,0,255);
color: #fff;
}
#myDIV2{
background-color: rgb(0,255,0);
color: #000;
}
.show{
display:block;
}
</style>
</head>
<body>
<nav>
<button onclick="myFunction1()">Dropdown1</button>
<button onclick="myFunction2()">Dropdown2</button>
</nav>
<div id="myDIV1">
This Dropdown for Dropdown 1
</div>
<div id="myDIV2">
This Dropdown for dropdown 2
</div>
<script>
function myFunction1() {
var element = document.getElementById("myDIV1");
element.classList.toggle("show");
}
function myFunction2() {
var element = document.getElementById("myDIV2");
element.classList.toggle("show");
}
</script>
</body>
</html>
here is the solution, all the code is commented.
div1 and div2 are hidden by default...
so with .toggle(): https://developer.mozilla.org/en-US/docs/Web/API/DOMTokenList/toggle
I will add the class .show if there isn't
else I will remove the class from it.
so if the user clicks the first time on the button it will show the div1 then if he reclicked will hide, and this is looped (if he reclick)...
with classList.remove, we will hide the other element (always):
if clicked the button N1 will hide div2
if clicked the button N2 will hide div1
let div1 = document.getElementById("myDIV1");
let div2 = document.getElementById("myDIV2");
function myFunction1() {
div1.classList.toggle("show");
// remove the class for the second div
div2.classList.remove("show");
}
function myFunction2() {
div2.classList.toggle("show");
// remove the class for the first div
div1.classList.remove("show");
}
nav {
width: 100%;
height: 50px;
background-color: #000;
}
button {
height: 50px;
margin-left: 10px;
border: 0;

}

height: 300px;
position: absolute;
}
#myDIV1 {
background-color: rgb(0, 0, 255);
color: #fff;
}
#myDIV2 {
background-color: rgb(0, 255, 0);
color: #000;
}
/* this is the class we add and remove or toggle with javascript*/
.show {
display: block;
}

You can make this a little easier to scale by using one function for all dropdown menus. This function closes all open drop-downs and toggles the target one.
function toggleDropDown(id) {
document.querySelectorAll('.dropdown-menu').forEach(el => el.id === id ? el.classList.toggle('show') : el.classList.remove("show"));
}
function toggleDropDown(id) {
document.querySelectorAll('.dropdown-menu').forEach(el => el.id === id ? el.classList.toggle('show') : el.classList.remove("show"));
}
nav {
width: 100%;
height: 50px;
background-color: #000;
}
button {
height: 50px;
margin-left: 10px;
border: 0;
background-color: transparent;
color: #fff;
cursor: pointer;
}
.dropdown-menu {
display: none;
width: 100%;
height: 300px;
position: absolute;
}
#myDIV1 {
background-color: rgb(0, 0, 255);
color: #fff;
}
#myDIV2 {
background-color: rgb(0, 255, 0);
color: #000;
}
.show {
display: block;
}
<nav>
<button onclick="toggleDropDown('myDIV1')">Dropdown1</button>
<button onclick="toggleDropDown('myDIV2')">Dropdown2</button>
</nav>
<div class='dropdown-menu' id="myDIV1">
This Dropdown for Dropdown 1
</div>
<div class='dropdown-menu' id="myDIV2">
This Dropdown for dropdown 2
</div>
Here is the same thing, but instead of hard-coding click events, it's better practice to use eventListeners, which get applied through the script after the page loads, like:
document.addEventListener('DOMContentLoaded', () => {
document.querySelectorAll('nav button').forEach(button => {
button.addEventListener('click', e => {
let id = e.target.dataset.dropdown
document.querySelectorAll('.dropdown-menu').forEach(el => el.id === id ? el.classList.toggle('show') : el.classList.remove("show"));
})
})
})
document.addEventListener('DOMContentLoaded', () => {
document.querySelectorAll('nav button').forEach(button => {
button.addEventListener('click', e => {
let id = e.target.dataset.dropdown
document.querySelectorAll('.dropdown-menu').forEach(el => el.id === id ? el.classList.toggle('show') : el.classList.remove("show"));
})
})
})
nav {
width: 100%;
height: 50px;
background-color: #000;
}
button {
height: 50px;
margin-left: 10px;
border: 0;
background-color: transparent;
color: #fff;
cursor: pointer;
}
.dropdown-menu {
display: none;
width: 100%;
height: 300px;
position: absolute;
}
#myDIV1 {
background-color: rgb(0, 0, 255);
color: #fff;
}
#myDIV2 {
background-color: rgb(0, 255, 0);
color: #000;
}
.show {
display: block;
}
<nav>
<button data-dropdown="myDIV1">Dropdown1</button>
<button data-dropdown="myDIV2">Dropdown2</button>
</nav>
<div class='dropdown-menu' id="myDIV1">
This Dropdown for Dropdown 1
</div>
<div class='dropdown-menu' id="myDIV2">
This Dropdown for dropdown 2
</div>

Dynamically Create a Modal for a Note Taker App

I am working on a simple note taking app using vanilla javascript. I am trying to have the program add the note with a modal that when clicked would show the text. With what I have so far it is adding the note below the input box and along with the modal button. When I click the modal button it does nothing the first click. On the second click the text and modal button disappear.

Javascript is the below that creates the note and then add it along with the modal
function addNote(){
var item = document.getElementById("inote").value
var text = document.createTextNode(item)
var newItem = document.createElement("P")
newItem.appendChild(text)
document.getElementById("noteList").appendChild(newItem)
var x = document.createElement("BUTTON");
x.id = "someId";
//x.onclick ="modalOpen()";
x.onclick = function(){
var modal = document.getElementById("noteList");
var btn = document.getElementById("someId");
btn.onclick = function() {
modal.style.display = "none";
}
};
var t = document.createTextNode("Open Modal");
x.appendChild(t);
document.getElementById("noteList").appendChild(x);
var z = document.createElement("BR");
document.getElementById("noteList").appendChild(z);
var newElem = document.createElement("BR");
document.getElementById("noteList").appendChild(newElem);
}
on first time, you are just attach event listener of click, simply put x.onclick outside the function
Hopefully this one will help.
So we have the "note-list" to handle the list.
I create a modal element that can activate when we click on the "new note" button.
In here I play with opacity and z-index to show this modal. Can be better than this.
const newNote = document.getElementById('new-note'),
addNote = document.getElementById('add-note');
let myModal = document.getElementById('my-modal');
newNote.addEventListener('click', () => {
myModal.style.zIndex = 99;
myModal.style.opacity = 1;
});
addNote.addEventListener('click', () => {
let note = document.getElementById('note'),
noteList = document.getElementById('note-list');
if (note.value !== '') {
let _el = document.createElement('li');
_el.innerHTML = note.value;
let _a = document.createElement('a');
_a.innerHTML = 'delete';
_el.appendChild(_a);
noteList.appendChild(_el);
note.value = '';
myModal.style.zIndex = -1;
myModal.style.opacity = 0;
_a.addEventListener('click', (e) => {
e.target.parentNode.remove();
});
} else {
alert('note can not empty');
}
});
#my-modal {

Change placeholder on link click in html

With below code I'm trying to change the placeholder for select element on link click. But no changes are seen as of now. Also I'm trying to figure out how to show div when click on gear icon. Currently it works when click on div but not for icon present in it.

You can try the following way:
$(function() {

.select2({

allowClear: true,
width: '200',
multiple: false,
data: [{
id: '',
text: ''

id: 'testing 1,2,3',
text: 'testing 1,2,3gffffff'
}],

})
.on('select2:open', function() {
$('.select2-container').css('width','600px');
})
.on("select2:close", function () {
$('.select2-container').css('width','200px');
});
$('#changeCommand').click(function() {
$('.select2-selection__placeholder').text('Search Command...');
});
$('#changePref').click(function() {
$('.select2-selection__placeholder').text('Search Preferences...');
});
$('#changeCD').click(function() {
$('.select2-selection__placeholder').text('Search Customer Default...');
});
});
// Close the dropdown if the user clicks outside of it
window.onclick = function(event) {
var dropdowns = document.getElementById("myDropdown");
if (event.target.classList.contains('dropbtn')) {
dropdowns.classList.toggle("show");
}
else if (!event.target.classList.contains("dropbtn") && dropdowns.classList.contains("show")){
dropdowns.classList.toggle("show");
}
}
.dropbtn {
background-color: #3498DB;
color: white;
padding: 8px;
font-size: 16px;
border: none;
cursor: pointer;
}
.dropbtn:hover, .dropbtn:focus {

}
.dropdown-content a {

display: block;
}

<a id="changePref">Preferences</a>
<a id="changeCD">Customer Default</a>
</div>
Just remove remove the subscription on the window.onclick event.
The onclick event on you button will be fired when child elements are clicked. Your current logic will show and directly hide the dropdown

How to add search bar to the dropdown?

Can anyone help me to add search bar as the first value of the dropdown? I used ASP.NET MVC. This is my code
<div class="col-md-8">
<div class="dropdown">
<div class="chzn-dd-width">
#Html.DropDownListFor(
model => model.DriverId,
Model.Drivers,
new { #id = "driverDropDown", #class = " form-control chosen-search" })
</div>
</div>
</div>
Hi Ravindu Saluwadana,
did you try this? solution add search functionality on DropDownListFor
#Html.DropDownListFor(x =>
x.StockCode,
(IEnumerable<SelectListItem>)ViewBag.AllStockList,
new
{
#class = "form-control selectpicker",
#Value = #Model.Description,
onchange = "this.form.submit();",
data_show_subtext="true",
data_live_search="true"
})
function myFunction() {
document.getElementById("myDropdown").classList.toggle("show");
}
function filterFunction() {
var input, filter, ul, li, a, i;
input = document.getElementById("myInput");
filter = input.value.toUpperCase();
div = document.getElementById("myDropdown");
a = div.getElementsByTagName("a");
for (i = 0; i < a.length; i++) {
if (a[i].innerHTML.toUpperCase().indexOf(filter) > -1) {
a[i].style.display = "";
} else {
a[i].style.display = "none";
}
}

you can use 3rd party plugin who allows multiple dropdowns such as multiselect, with new styles , and also search
use this SELECT2 Dropdown Plugin
https://select2.org/searching
Use this functionality- data_live_search="true" in the dropdownlistfor.
To use that functionality you have to use this following scripts -
1.bootstrap-select.min.js
2.boostrap-select.min.css
you can download that files from here - https://cdnjs.com/libraries/bootstrap-select
Example -
<div class="col-md-8">
<div class="dropdown">
<div class="chzn-dd-width">
#Html.DropDownListFor(
model => model.DriverId,
Model.Drivers,
new { #id = "driverDropDown", #class = " form-control chosen-search" ,data_live_search="true"})
</div>

I hope it will help you.

How to center all list's elements to parent div

I am going to add dynamically elements to my block of ul.
I would like to center all list's elements to parent div(brown boder).
For example,
if the resolution of the browser allows you to set two blocks in one row, I would like to center this row in relation to parent div.
I would be very graftefully.

myCode:
<!doctype html>
<html>
<head>
<script src="http://code.jquery.com/jquery-1.11.0.min.js"></script>
<script src="http://code.jquery.com/jquery-migrate-1.2.1.min.js"></script>
<script>
var tab = [2,3,4,5,7,8,9,11,12,13,14,15];
$(document).ready(function(){
$('#godziny').on('click', '.godzina', function(){
//alert(this.attr('class'));
$('.yb').removeClass('yb');
$(this).addClass('yb');
});
$('#getElements').click(function() {
for(i = 0; i < tab.length; ++i) {
alert(tab[i]);
setTimeout(function(i){
$('#godziny').append('<li class="godzina">' + tab[i] + '</li>');

You can use the CSS flexbox to achieve this. Here is a link to a complete guide on how to use flexbox. I hope this helps.
https://css-tricks.com/snippets/css/a-guide-to-flexbox/
Add this lines:
CSS
#wybor_terminu ul {
list-style-type: none;
overflow: hidden;
/*NEW*/
padding: 0;
width: 100%;
}
#wybor_terminu ul li {
width: 200px;
height: 200px;
text-align: center;
color: blue;
border: 0.2em solid green;
/*float: left; You don't need this line*/
cursor: pointer;
/*NEW*/
margin:auto;
margin-top: 40px;
}
EDIT
This is only a quick solution with bootstrap maybe it could help you a little bit. jsfiddle
jQuery
In this line I added bootstrap classes:
$('#godziny').append('<li class="godzina col-sm-12 col-md-6">' + tab[i] + '</li>');
This code center your boxes (is not the best solution, but it works):
countBoxes = $('#godziny').width() / 200;
alignBoxes = ($('#godziny').width()-(200*parseInt(countBoxes)))/2;
if(countBoxes >= 2.65){
$('#godziny').css('margin-left', alignBoxes);
} else{
$('#godziny').css('margin-left', 0);
}
If you change the resolution of your screen, click the button to center your boxes again.
