HTML

All the HTML you need

<h1>Work Day Scheduler</h1>
<h3>A simple calendar app for scheduling your work day</h3>
<div class="Scheduler"></div>

JavaScript

We’ll use Window.localStorage to save the data so that the user can exit or refresh the page.

Create a 24h to AM/PM converter:

const ampm = h => (h%12||12)+(h<12?'AM':'PM');

Use Window.localStorage to read (and store) your LS Object in the Browser memory.

const LS = JSON.parse(localStorage.scheduler||'{}'); // String is now an Object

Create and store the HTML template as JS String

const template_schedule = h => `<div class="Schedule">
    <div class="Schedule-time">${ampm(h)}</div>
    <textarea class="Schedule-desc" data-h="${h}">${LS[h]||''}</textarea>
    <div class="Schedule-save">SAVE</div>
  </div>`;

and append that string into the DOM using Element.insertAdjacentHTML given a start from and end to hour:

for (let h=from; h<=to; h++) {
  EL_scheduler.insertAdjacentHTML('beforeend', template_schedule(h))
} 

Now the fun part.
Save on textarea blur!
The textarea can be blurred by clicking outside of the textarea – on the “SAVE” element or anywhere else. So it’ll work in every case. (Show the transparent “SAVE” text by using CSS :focus and the adjacend sibling combinator +)

const save = ev => {
  const h = ev.target.getAttribute('data-h');  // Get the hour
  LS[h] = ev.target.value;                     // Update Object 
  localStorage.scheduler = JSON.stringify(LS); // Store into localStorage as string
};

EL_scheduler.querySelectorAll('.Schedule-desc').forEach(el => {
  el.addEventListener('blur', save);
});

Live example:

Since StackOverflow sandboxes the live-snippet iframe and the localStorage will not work – head to this jsFiddle DEMO


And here’s the SO-Snippet for completeness sake:

const from = 9;   // use 24h format here
const to   = 17;  // use 24h format here

// Use window.localStorage to retrieve and store your data object as string
const LS = JSON.parse(localStorage.scheduler||'{}'); // now an Object

const EL_scheduler = document.querySelector('.Scheduler');

const ampm = h => (h%12||12)+(h<12?'AM':'PM');

const template_schedule = h => `<div class="Schedule">
    <div class="Schedule-time">${ampm(h)}</div>
    <textarea class="Schedule-desc" data-h="${h}">${LS[h]||''}</textarea>
    <div class="Schedule-save">SAVE</div>
  </div>`;

// Populate Scheduler
for (let h=from; h<=to; h++) {
  EL_scheduler.insertAdjacentHTML('beforeend', template_schedule(h))
}

// Logic to save the data:
// On textarea blur Event - save the data by reading the data-h value
const save = ev => {
  const h = ev.target.getAttribute('data-h');  // Get the hour
  LS[h] = ev.target.value;                     // Update Object 
  localStorage.scheduler = JSON.stringify(LS); // Store into localStorage as string
};

EL_scheduler.querySelectorAll('.Schedule-desc').forEach(el => {
  el.addEventListener('blur', save);
});

<h1>Work Day Scheduler</h1>
<h3>A simple calendar app for scheduling your work day</h3>
<div class="Scheduler"></div>

Problem :

I am trying to set-up this daily scheduler. I am working on the 9am slot. What I want to happen is for the person to click on the box to the right of the time, make a text input, and click the save button to save the text and display it in that time slot.

Am I able to achieve this with just HTML or will I need to implement JS to make this work?

What should happen on save? What if a user refreshes the page?
