Bootstrap 4 localstorage notes

This script allows you to add notes to any “input” field on your page. This extension utilizes the localstorage option, so this means the notes are ONLY ON YOUR CURRENT BROWSER.


Bootstrap 4/5; JQuery


Download js/dynamic_notes.js and include it in your HTML file. Start it:

<script src="js/dynamic_notes.js"></script>
    $(function () {
        // Options for the extension
        const notesBSOptions = {
            // the base key name under which to save the notes
            key: 'test',
            // the class for which to look to init the notes. At this point ths MUST by input
            convertClass: 'haveNote',
            // Optional - use Google Material Symbols to display icons
            useIcons: true

        // init it

The supported settings are:

const defaults = {
    // These are the defaults.

    //Default key name. This can later be put to URL
    key: "BS4_notes",
    //Expire time in hours
    expireAfter: 168,
    //Name of the class of the inputs
    convertClass: "haveNote",
    // Use an icon font
    useIcons: true,
    // Default Google Icon for Add a Note
    iconAddNote: '<span class="material-symbols-outlined fs">note_add</span>',
    // Default Google Icon for Existing Note
    iconExistingNote: '<span class="material-symbols-outlined fs">note</span>',
    // Default Google Icon for Remove an icon
    iconRemoveNote: '<span class="material-symbols-outlined fs">delete</span>',
    // Container for recorded notes
    recordedNotesContainer: "#notesContainer",
    // Bootstrap version
    bootstrapVersion: '4'

The extension is built with support for Google Material Icons:

<!-- This is Google Material Icons, used for icons -->
<link rel="stylesheet" href=""/>

Some styling for Google Icons and the notes container:

    /* Some settings for Google Material Icons */
    .material-symbols-outlined {
        font-variation-settings: 'FILL' 0,
        'wght' 400,
        'GRAD' 0,
        'opsz' 17

    .fs {
        font-size: 17px;
        max-width: 17px;
        max-height: 17px;

    /* Some settings for Google Material Icons */

    /* This is the container for recorded notes. Change it accordingly */
    #notesContainer {
        position: absolute;
        top: 5px;
        right: 5px;
        width: 150px;

    /* This is the container for recorded notes. Change it accordingly */

HTML example code. Notice, the extension works with both input-group and without it.

<label for="search_test">Just a small test with existing input group</label>
<div class="input-group">
    <input type="text" class="form-control haveNote" name="ean_code" id="search_test"/>
    <div class="input-group-append">
        <div class="input-group-button">
            <button type="button" class="btn btn-success" id="addNote" data-toggle="modal" data-target="#addNoteModal">
                <span class="material-symbols-outlined fs">
<label for="other_code">Add some more dynamic shit</label>
<input type="text" class="form-control haveNote" name="other_code" id="other_code" data-note-title="Dynamic note"/>

There must be a modal to handle the adding of new notes. The id of this modal can be send via the options, and inside the modal modal-body you must insert these:

<form method="post" action="/" id="addNoteForm" novalidate>
    <label for="noteTitle">Note title</label>
    <input type="text" name="noteTitle" class="form-control" id="noteTitle" required/>
    <div class="invalid-feedback">
        Enter a title!
    <label for="noteContent">Note</label>
    <input type="text" name="noteContent" class="form-control" id="noteContent" required/>
    <div class="invalid-feedback">
        Enter a note!
    <input type="hidden" name="noteName" class="form-control" id="noteName"/>

How it works?

When BS4 Notes starts, it adds a button, which shows a modal on click event. Inside of the modal you can fill the “id” of the note and its content. This “id” is used later to track down if you entered it in the same input, the extension displays the note in a dedicated div below it with the note.
