This JavaScript source code helps you to create draggable sticky notes on a webpage. The code lets you add and drag sticky notes freely across the page. It allows you to input titles and text for each note and easily delete them. This functionality makes organizing information or reminders interactive and visual.

How to Create Sticky Notes Javascript Source Code

1. First of all, add the necessary HTML structure to your webpage. Include a container for the sticky notes and a form to input titles and text for new notes. Use the given classes and IDs as shown in the code.

<div id="stickies-container"></div>
        <div class="sticky-form">
            <label for="stickytitle">Title for your sticky:</label>
            <input type="text" name="stickytitle" id="stickytitle" />
            <label for="stickytext">Write something down:</label>
            <textarea
                name="stickytext"
                id="stickytext"
                cols="24"
                rows="10"
            ></textarea>
            <button class="button" id="createsticky">Stick it!</button>
        </div>

2. Use the following CSS styles to design the appearance of the sticky notes and the form. The CSS defines the colors, sizes, and positioning for the sticky notes and their form.

html {
  box-sizing: border-box;
  font-family: 'Courier New', Courier, monospace;
}
body {
  background: linear-gradient(to left bottom, #41d8dd, #5583ee) !important;
  min-height: 100vh;
  height: 100%;
  margin: 0;
  position: relative;
  /* overflow: hidden; */
}
#stickies-container {
  padding: 1rem;
}
.drag {
  -webkit-touch-callout: none;
  -webkit-user-select: none;
  -khtml-user-select: none;
  -moz-user-select: none;
  -ms-user-select: none;
  user-select: none;
}
.sticky {
  background: linear-gradient(to left bottom, #d4fc78, #99e5a2);
  box-shadow: 0 0 20px rgba(0, 0, 0, 0.3);
  color: #00243f;
  /* 0 0 150px rgba(0, 0, 0, 0.2); */
  cursor: grab;
  display: inline-block;
  padding: 1rem;
  position: absolute;
  width: 12.5rem;
}
.sticky h3,
.sticky p {
  /* color: #0065b3; */
  color: #00243f;
  pointer-events: none;
}
.sticky h3 {
  border-bottom: dashed 2px #0085e8;
  margin: 0 0 1rem;
  min-height: 1.3rem;
  padding: 0 1.5rem 0.25rem 0;
}
.sticky p {
  margin: 0;
  min-height: 9rem;
}
.sticky .deletesticky {
  color: #0085e8;
  cursor: pointer;
  font-size: 2rem;
  position: absolute;
  right: 0.8rem;
  top: 0.4rem;
}

.sticky-form {
  bottom: 1rem;
  position: absolute;
  right: 1rem;
}
.sticky-form label,
.sticky-form input,
.sticky-form textarea {
  color: #fff;
  display: block;
}
.sticky-form input,
.sticky-form textarea {
  background-color: #f0f9ff44;
  background-clip: padding-box;
  border: 2px dashed #0065b3;
  border-radius: 0.25rem;
  color: #00243f;
  font-family: 'Courier New', Courier, monospace;
  font-size: 1rem;
  font-weight: 400;
  line-height: 1.5;
  margin-bottom: 0.75rem;
  padding: 0.375rem 0.75rem;
  width: calc(100% - 1.5rem);
}
.sticky-form input:focus,
.sticky-form textarea:focus {
  border: 2px dashed #ffffff;
  outline: none;
}
button.button {
  -moz-user-select: none;
  -ms-user-select: none;
  -webkit-user-select: none;
  background-color: #d4fc78;
  border-radius: 0.25rem;
  border: 1px solid transparent;
  color: #0065b3;
  display: inline-block;
  font-family: 'Courier New', Courier, monospace;
  font-size: 1rem;
  font-weight: 600;
  line-height: 1.5;
  padding: 0.375rem 0.75rem;
  text-align: center;
  user-select: none;
  vertical-align: middle;
}

3. Finally, implement the JavaScript functionality to enable the creation, dragging, and deletion of sticky notes. Place the following JavaScript code within a <script> tag at the end of the HTML file or in an external JavaScript file. Make sure the JavaScript is executed after the DOM content is loaded using an event listener (DOMContentLoaded).

'use strict';
document.addEventListener('DOMContentLoaded', () => {
const stickyArea = document.querySelector(
'#stickies-container'
);

const createStickyButton = document.querySelector(
'#createsticky'
);

const stickyTitleInput = document.querySelector('#stickytitle');
const stickyTextInput = document.querySelector('#stickytext');

const deleteSticky = e => {
e.target.parentNode.remove();
};

let isDragging = false;
let dragTarget;

let lastOffsetX = 0;
let lastOffsetY = 0;

function drag(e) {
if (!isDragging) return;

// console.log(lastOffsetX);

dragTarget.style.left = e.clientX - lastOffsetX + 'px';
dragTarget.style.top = e.clientY - lastOffsetY + 'px';
}

function createSticky() {
const newSticky = document.createElement('div');
const html = `<h3>${stickyTitleInput.value.replace(
/<\/?[^>]+(>|$)/g,
''
)}</h3><p>${stickyTextInput.value
.replace(/<\/?[^>]+(>|$)/g, '')
.replace(
/\r\n|\r|\n/g,
'<br />'
)}</p><span class="deletesticky">&times;</span>`;
newSticky.classList.add('drag', 'sticky');
newSticky.innerHTML = html;
//newSticky.style.backgroundColor = randomColor();
stickyArea.append(newSticky);
positionSticky(newSticky);
applyDeleteListener();
clearStickyForm();
}
function clearStickyForm() {
stickyTitleInput.value = '';
stickyTextInput.value = '';
}
function positionSticky(sticky) {
sticky.style.left =
window.innerWidth / 2 -
sticky.clientWidth / 2 +
(-100 + Math.round(Math.random() * 50)) +
'px';
sticky.style.top =
window.innerHeight / 2 -
sticky.clientHeight / 2 +
(-100 + Math.round(Math.random() * 50)) +
'px';
}

function editSticky() {}

function stripHtml(text) {
return text.replace(/<\/?[^>]+(>|$)/g, '');
}

function randomColor() {
const r = 200 + Math.floor(Math.random() * 56);
const g = 200 + Math.floor(Math.random() * 56);
const b = 200 + Math.floor(Math.random() * 56);
return 'rgb(' + r + ',' + g + ',' + b + ')';
}

function applyDeleteListener() {
let deleteStickyButtons = document.querySelectorAll(
'.deletesticky'
);
deleteStickyButtons.forEach(dsb => {
dsb.removeEventListener('click', deleteSticky, false);
dsb.addEventListener('click', deleteSticky);
});
}

window.addEventListener('mousedown', e => {
if (!e.target.classList.contains('drag')) {
return;
}
dragTarget = e.target;
dragTarget.parentNode.append(dragTarget);
lastOffsetX = e.offsetX;
lastOffsetY = e.offsetY;
// console.log(lastOffsetX, lastOffsetY);
isDragging = true;
});
window.addEventListener('mousemove', drag);
window.addEventListener('mouseup', () => (isDragging = false));

createStickyButton.addEventListener('click', createSticky);
applyDeleteListener();
});
