I'm trying to make a Single Page Application with pure JavaScript (no additional frameworks or libraries). The problem is that the values I add to the TODO list are not storing in the localStorage (and are not showing).
I would appreciate any help with that task.
How can I simplify the code? (without using any additional libraries and frameworks (ex.jquery etc.))
Here is my code:
let inputTask = document.getElementById('toDoEl');
let editTask = document.getElementById('editTask');
let checkTask = document.getElementById('list');
let emptyList = document.getElementById('emptyList');
let items = [];
let id = [];
let labelToEdit = null;
const empty = 0;
let pages = ['index', 'add', 'modify'];
load();
function load() {
items = loadFromLocalStorage();
id = getNextId();
items.forEach(item => renderItem(item));
}
function show(shown) {
location.href = '#' + shown;
pages.forEach(function(page) {
document.getElementById(page).style.display = 'none';
});
document.getElementById(shown).style.display = 'block';
return false;
}
function getNextId() {
for (let i = 0; i<items.length; i++) {
let item = items[i];
if (item.id > id) {
id = item.id;
}
}
id++;
return id;
}
function loadFromLocalStorage() {
let localStorageItems = localStorage.getItem('items');
if (localStorageItems === null) {
return [];
}
return JSON.parse(localStorageItems);
}
function saveToLocalStorage() {
localStorage.setItem('items', JSON.stringify(items));
}
function setChecked(checkbox, isDone) {
if (isDone) {
checkbox.classList.add('checked');
checkbox.src = 'https://image.ibb.co/b1WeN9/done_s.png';
let newPosition = checkTask.childElementCount - 1;
let listItem = checkbox.parentNode;
listItem.classList.add('checked');
checkTask.removeChild(listItem);
checkTask.appendChild(listItem);
} else {
checkbox.classList.remove('checked');
checkbox.src = 'https://image.ibb.co/nqRqUp/todo_s.png';
let listItem = checkbox.parentNode;
listItem.classList.remove('checked');
}
}
function renderItem(item) {
let listItem = document.getElementById('item_template').cloneNode(true);
listItem.style.display = 'block';
listItem.setAttribute('data-id', item.id);
let label = listItem.querySelector('label');
label.innerText = item.description;
let checkbox = listItem.querySelector('input');
checkTask.appendChild(listItem);
setChecked(checkbox, item.isDone);
emptyList.style.display = 'none';
return listItem;
}
function createNewElement(task, isDone) {
let item = { isDone, id: id++, description: task };
items.push(item);
saveToLocalStorage();
renderItem(item);
}
function addTask() {
if (inputTask.value) {
createNewElement(inputTask.value, false);
inputTask.value = '';
show('index');
}
}
function modifyTask() {
if (editTask.value) {
let item = findItem(labelToEdit);
item.description = editTask.value;
labelToEdit.innerText = editTask.value;
saveToLocalStorage();
show('index');
}
}
function findItem(child) {
let listItem = child.parentNode;
let id = listItem.getAttribute('data-id');
id = parseInt(id);
let item = items.find(item => item.id === id);
return item;
}
// Chanhe img to checked
function modifyItem(label) {
labelToEdit = label;
editTask.value = label.innerText;
show('modify');
editTask.focus();
editTask.select();
}
function checkItem(checkbox) {
let item = findItem(checkbox);
if (item === null) {
return;
}
item.isDone = !item.isDone;
saveToLocalStorage();
setChecked(checkbox, item.isDone);
}
function deleteItem(input) {
let listItem = input.parentNode;
let id = listItem.getAttribute('data-id');
id= parseInt(id);
for (let i in items) {
if (items[i].id === id) {
items.splice(i, 1);
break;
}
}
if (items.length === empty) {

Your code does appear to work. If you console.log(JSON.parse(localStorageItems)) right above line 49 in the loadFromLocalStorage function, it shows as expected in the console. Also, upon refreshing the items persist.
If what you mean is that you're checking localStorage and you don't see the items, it might be that you're looking at the preview version of localStorage. (I'm assuming you're using Chrome.) Hover over the top of the empty section and pull down, this should reveal the values stored. If you click on one, it should show in the preview section. I think this was a Chrome dev tools UI change recently implemented.
I checked your code in Codepen and it works.
Why can't character.setAttribute() work. If you delete the line, the
format of what I am trying to accomplish is there, but the CSS for the letters don't make it invisible. If I do put the setAttribute() in, the code doesn't work.

A TextNode doesn't have attributes.
character = document.createElement('li');

I am guessing you want to do:
character = document.createElement('span');
character.appendChild(document.createTextNode(hangmanWord[i]));
character.classList.add('hidden');
underscores.appendChild(character);
Working example:
var possibleWord = ["cow", "better", "harder", "justify", "condemn",
"control", "hello", "understand", "life", "insight", "date", "righteous"
];
var hangmanWord = possibleWord[Math.floor(Math.random() *

window.onload = function() {

placement.appendChild(underlineHelp);
for (i = 0; i < hangmanWord.length; i++) {
underscores = document.createElement('li');
underscores.setAttribute('class', 'boxes');
guesses.push(underscores);
underlineHelp.appendChild(underscores);
character = document.createElement('span');
character.appendChild(document.createTextNode(hangmanWord[i]));
character.classList.add('hidden');

I would like to create an on click button to run a javascript function to generate a grid in the style of a crossword.
I have written some javascript to create the grid and I have made the button with the onclick function, but I am unable to get the button to run the script.
I'm sure the solution is glaringly obvious but I'm new to coding so any and all help would be appreciated!
<html>
<body>
<!--<button onclick="generateGrid()">Click to generate crossword grid</button>-->
<div id="crosswordGrid" align="center"></div>
</body>
</html>
function generateGrid () {
var crosswordGrid = document.getElementById("crosswordGrid");
for (var r = 0; r < rows; r++) {
var row = crosswordGrid.appendChild(document.createElement("div"));
for (var c = 0; c < cols; c++) {
row.appendChild(document.createElement("span"));
}
}
const gridSize = 7;
var rows = gridSize;
var cols = gridSize;
}
This is what my current code looks like;
http://jsfiddle.net/YEJ9A/97/
So I think you were mostly the way there. I moved the values you were assigning at the bottom of the file into the default value of the function. See the corrections below.
Also updated on fiddle. https://jsfiddle.net/r8aLbakr/1/
function generateGrid (gridSize = 7, rows = 7, cols = 7, crosswordGrid) {
var crosswordGrid = document.getElementById("crosswordGrid");
for (var r = 0; r < rows; r++) {
var row = crosswordGrid.appendChild(document.createElement("div"));
for (var c = 0; c < cols; c++) {
row.appendChild(document.createElement("span"));
}
}
}
#crosswordGrid div {
line-height: 1px;
}
#crosswordGrid span {
display: inline-block;
width: 28px;
height: 28px;
border: 1px solid black;
}
#crosswordGrid div:nth-child(even) span:nth-child(even) {
background-color: black;
}
#crosswordGrid div:nth-child(odd) span:nth-child(odd) {
background-color: white;
}
<html>
<body>
<button onclick="generateGrid()">Click to generate crossword grid</button>
<div id="crosswordGrid" align="center"></div>
</body>
</html>
Try to use "addEventListener" instead of "onclick"
here is my answer
Code:
document.getElementById ("btn").addEventListener("click", function() {
generateGrid(7);
} , false);
function generateGrid(gridSize) {
var rows = gridSize;
var cols = gridSize;
var crosswordGrid = document.getElementById("crosswordGrid");
for (var r = 0; r < rows; r++) {
var row = crosswordGrid.appendChild(document.createElement("div"));
for (var c = 0; c < cols; c++) {
row.appendChild(document.createElement("span"));
}
}
}
#crosswordGrid div {
line-height: 1px;
}
#crosswordGrid span {
display: inline-block;
width: 28px;
height: 28px;
border: 1px solid black;
}
#crosswordGrid div:nth-child(even) span:nth-child(even) {
background-color: black;
}
#crosswordGrid div:nth-child(odd) span:nth-child(odd) {
background-color: white;
}

I have created a calculator I use for counting carbs for my 7 y/o type 1 diabetic but as I add more values into my array the page is getting too long.
I'm looking for a way to start with a single select for the food name then select the weight and it calculates the carbs. Then have a button to dynamically add another row to the form in order to select a new food item and calculate the results of any further additions.
This is my functional code base:

input[type="text"][disabled] {width: 12%; background-color: white; color: black; font-weight: bolder;}
input[type="button"] {}
select {width: 15%}
</style></head>
<body>
<script language="javascript" type="text/javascript">

function reset(){
var t=0;
for (var i=0; i<myArray.length; i++) {
var v = "val"+i;
document.calc.elements[v].value=0;
}
}
function calculate(){
var t=0;
var tt=0;
for (var i=0; i<myArray.length; i++) {
var v = "val"+i;
var a = "answer"+i;
if(isNaN(parseInt(document.calc.elements[v].value))) {
//document.calc.elements[a].value="";
} else {
tt=(parseInt(document.calc.elements[v].value))* myArray[i][1];
document.calc.elements[a].value=tt.toFixed(1);
t+=tt;
}
}
document.calc.answerTot.value=(t).toFixed(1)
}
document.write("<form name=\"calc\" action=\"post\">");

Hello there and welcome to StackOverflow!
Your code required a bit of rework and questions like that (more like a task than a question) aren't usually very successful around here.
Having said that, I wrote something that will hopefully help you, the nice thing about it being that if you want to add new types of food you'll only need to add them in the array and the js will take care of it.
Careful with the approximation to 1 digit though, you might lose some carbs in the calculation. Also, please check your carbs, see if I haven't modified anything by mistake.

If anyone wants to see the result, this is what I ended up with. I added a couple event listeners and made the weight value a select rather than an input. Thanks again #Paul for the assistance this is exactly what I was trying to accomplish!

Here is a small application I came up with that could also suit your needs.
It consists of five files that should be located in the same directory.
Best of health for your child!
Features include:
adding and removing of new food types
adding and removing food to/from multiple lists
changing, increasing and decreasing count of fooditems in lists
manage (add,remove,rename) multiple lists
save and load data in your browser locally
export and import data through a text area to save your data externally.
layout support for both big screen and handheld devices

Technical Notes:
I am using pure Javascript and css. Some styles might not be compatible with older browsers like Internet Explorer prior to Edge.
Saving of data is handled through the browsers local storage.
Import and Export is handled through plain text in "Javascript Object Notation" (JSON).
The Application itself is written as a Javascript Class e.g. Function named MyCarbCalculator which is created and initialized through the bodies onload event and an init() function.
With this example application I'm trying to show how to use Javascript in a structured (pseudo object oriented) way and the power and flexibility of event listeners and unnamed functions e.g. the use of functions as parameters.
Also I am using CSS media descriptors to create a flexible layout that can be customized for both handheld devices and big screens. This is mostly done through the "flexbox" style which allows for very fluid layouts and offers great control over the positioning of elements.
I'm creating a memory game for my web assignment at uni and I am stuck on how to get my animation playing on match on top of the cards that match.
At the moment, I have been able to get the animation to play on click of the memory_board div, but only works once.
So question 1 - How do you get the animation to work every time you click on the Memory_board div.(It only works once atm, and have to refresh the page to play it again)
My code for the animation to work is:
.sprite {
width:96px;
height:96px;
position: relative;
margin:15px;
}
.toon{
background: url(explode.png);
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script type='text/javascript' src='jquery.animateSprite.js'></script>
<script>//sparkle effect: http://www.rigzsoft.co.uk/how-to-implement-animated-sprite-sheets-on-a-web-page/
$(document).ready(function(){
$("#memory_board").click(function animation(){
$(".toon").animateSprite({
columns: 10,
totalFrames: 50,
duration: 1000,
});
});
});
</script>
<body>
<div class = "grid_10">
<div id="memory_board"></div>
<script>newBoard();</script>
<div style="position: relative; height: 110px;">
<div class="sprite toon"></div>
</div>
</div>
</body>
Question 2 - How will I place this animation over top of each card?
The layout of the board is by float in the memory_boarddiv, where the images are in an array and called up in the function tile.innerHTML = '<img src="' + val + '.png"/>';
Here is the full coding for the board:
div#memory_board{
background: -webkit-radial-gradient(#FFF, #CC99FF); /* For Safari 5.1 to 6.0 */
background: -o-radial-gradient(#FFF, #CC99FF); /* For Opera 11.1 to 12.0 */
background: -moz-radial-gradient(#FFF, #CC99FF); /* For Firefox 3.6 to 15 */
background: radial-gradient(#FFF, #CC99FF); /* Standard syntax (must be last) */
border:#FF0066 10px ridge;
width:510px;
height:405px;
padding:24px;
}
div#memory_board > div{
background:url(tile_background.png) no-repeat;
border:#000 1px solid;
width:45px;
height:45px;
float:left;
margin:7px;
padding:20px;
cursor:pointer;
}

Question 3 - How will I get to play this animation only on match, on top of the cards that have matched.
I'm guessing this is done by putting it into the memoryFlipTile function under the //animation where the sound and match number change upon a match found :
function memoryFlipTile(tile,val){
startTimer();
playClick();
if(tile.innerHTML == "" && memory_values.length < 2){
tile.style.background = '#FFF';
tile.innerHTML = '<img src="' + val + '.png"/>';
if(memory_values.length == 0){
memory_values.push(val);
memory_tile_ids.push(tile.id);
} else if(memory_values.length == 1){
memory_values.push(val);
memory_tile_ids.push(tile.id);
if(memory_values[0] == memory_values[1]){
tiles_flipped += 2;
//sound
playMatch();
//animation
//number of clicks
turns = turns + 1;
document.getElementById("Count").innerHTML = turns;
//number of matches
matches = matches + 1;
document.getElementById("matchNumber").innerHTML = matches;
// Clear both arrays
memory_values = [];
memory_tile_ids = [];
}
