I am making a simple list and each time the user enters writes something in a form, it gets added to an unordered list. However once the page is reloaded, the li disappears. I've read something about local storage to solve this problem but i have no idea how to use it or even if that is the right solution. I don't know if it'll help but here is my code.

Yep, you can use localStorage pretty easily for this! Make your javascript look something like this
//This will set the list HTML if it exists in localstorage
if (localStorage.listHTML) {
$("ul").html(localStorage.listHTML);
}
$("button").click(function() {
var input = $('input').val();
$("ul").append("<li>" + input + "</li>");
//This will update the value that is in localStorage when you add a new item
localStorage.listHTML = $("ul").html();
});
You could even add a button to reset the localStorage on click.
$("#reset").click(function() {
$("ul").html("");
localStorage.listHTML = "";
});

Why my javascript not work? When I change the innterHtml of an element, it didn't work?

checklogin()
There is no any errors in console!
but if I get document.getElementById('ll').innterHtml I saw the change, but there is no changes in html!
This page is the 404 page of github page, I changed some codes.
I change innter to inner
Image
I use vscode
And chrome
It is weird you don't have errors in console. Be carfeully about the uppercase letters, the correct attribute is innerHTML instead of innerHtml
You have a syntax problem. Put innerHTML instead of innterHtml

I am currently making a chrome extension (This is my first chrome extension) that you can take small notes with and want to keep the user input. I am keeping the user input inside of input classes. How would I be able to store the chrome extension state so that when I reopen it, it will stay the same? Here is the code that I have written so far.
//selectors
const addbutton = document.querySelector(".add");
const addlist = document.querySelector(".note-list");
const noteList = document.querySelector(".note-list")
//event listners
addbutton.addEventListener('click', addNote);
//functions
function addNote(event){
//prevent page refresh
event.preventDefault();
//note div
const noteDiv = document.createElement('div');
noteDiv.classList.add('note');
//create li
const newNote = document.createElement('li');
newNote.classList.add('noteitem');
noteDiv.appendChild(newNote);
//create input
const newInput = document.createElement('input');
newInput.classList.add('noteInput')
newNote.appendChild(newInput);
//append to list
noteList.appendChild(noteDiv);
}

// uses local storage
chrome.storage.local.set({key: value}, function() {
console.log('Value is set to ' + value);
});
// uses synced storage, hits Chrome backend when being set
chrome.storage.sync.set({key: value}, function() {
console.log('Value is set to ' + value);
});
// to retrieve the data, use 'sync' instead of 'local' if using sync
chrome.storage.local.get(['key'], function(result) {
console.log('Value currently is ' + result.key);
});
You'll still need to figure out how you want to organize the note data. For example, you could store all of the notes in an array on the notes key that looks like the following:
{
notes: [
{ id: 1, body: 'First note' },
{ id: 2, body: 'Second note' }
]
}
you have two options :-
you can use localStorage just like in web page for more check here
you can use chrome.storage for more check here
I am making a simple socket.io app which you can see at https://backchannel.glitch.me. I am trying to add a relatively simple profanity filter for this site using RegExp, but I keep running into a problem- instead of displaying the message I want it to when a bad word is detected, nothing happens. I'm pretty inexperienced with JS and Regular Expressions, so there could be something i've overlooked and I would appreciate any help.

Comparing a string with a RegExp object with a boolean operator will always return false. You want to use the test method of RegExp for this. For example:
new RegExp("*bad words*").test(msg);
Also, there exists a shorthand syntax for constructing a regex.
/myregex/.test(msg);
I try to load an array from an external JS file into my HTML and have problems with that.
My js.js:
var temp_max = [4,9,2,5,8,4,2,10];

Note: Please download this file DateJS and insert it into "DATE-JS"!!

Here is a screenshot without importing the JS array.
So I want that my temp_max array values are displayed exactly above the German weekdays!
So above the first information: 'Donnerstag' the script should display the value 4 from the array and so on.
Please note that I want to export this array from an external JS-file, I am not able to write this variable into my HTML file!
I already tried to use
document.getElementById
but this does not work for me.
If the problem just in looping over the created divs, I think you can do this.
All what you need to change is just adding a different ids to your divs.
Just use i index in your ids.
Something like this:
Creation:
for(var i = 0 ; i <8 ; i++) {
var weekday=Date.today().addDays(i).toString('dddd');
document.write("<div id='div_weekday_" + i + "'>" + weekday + "</div>");
}
Updating data:
for (var i = 0; i < 8; i++) {
document.getElementById('div_weekday_' + i).innerHTML = temp_max[i].weekday;
}
I’ currently working on a website, where a user should be able to write and insert new songs with belonging chords into a database.
To sum things up, and get to the point pretty quick, here is my problem:
I have a div with the id “#textarea”, and the attribute contenteditable=“true”. On each enter/linebreak, I would like to create a new div with the class “.chords” and the attribute contenteditable=“false”. This ".chords" div should be placed right before the new line, like the image shows here:
The red color is the #textarea div, and the blue color the .chords divs
So my question is: how do I do this?
I’ve posted the code I've tried in the end of this post, but as you see if you run it, the .chords divs are positioned below the new line, so I’m now a bit stuck.. If any of you guys have an idea on how to do this, please let me hear from you!
$(function(e) {
$('#textarea').keydown(function(e) {
var i = 0;
// Check if the returnkey is being pressed
if (e.keyCode === 13) {
$("#textarea div:last-of-type").after("<div class=\"chords\" id=\"" + (i + 1) + "\" contenteditable=\"false\"></div>");
i = i + 1;
}
});
})
#textarea {
border: 1px solid black;
line-height: 50px;
font-size: 20px;
}
.chords {
height: 30px;
border: 1px solid black;
