I have several inputs, which I am copying n times and I am trying to add numeric values from inputs in the array. I marked word "add" because an array may be already filled by other numbers.
I'm trying to apply method from UncleDave's answer here:
JavaScript - Add Value from input box to array
Example:
I have an array:
var exampleArray = [[1, 1.5], [1, 1], [0, 25.5]];
What I have done:
Wrote value 25 in first input. Wrote value 1.5 in the second input.
Create two new inputs.
Wrote value 25.4 in first input. Wrote value 1 in the second input.
Pressed button for adding into an array.
What I am trying to reach:
var exampleArray = [[1, 1.5], [1, 1], [0, 25.5], [25, 1.5], [25.4, 1]];
What I have reached:
"Udefined" in the console log.

The getElementsByClassName() method returns a collection of all
elements in the document with the specified class name, as a NodeList
object.
You can iterate over the collections for all the numeric inputs and update your result. But I would suggest is to create another class for numeric inputs, so you wouldn't need to check for the type of the input and would keep your code generic.
You can try this code and feel free to clear your doubts in the comments.
function guardarNumeros() {
boxvalue = document.getElementsByClassName('myInput');
i = 0;
while (i < boxvalue.length) {
if (boxvalue[i].type == "number") {
if (boxvalue[i+1] && boxvalue[i+1].type == "number") {
tmp = [boxvalue[i].value, boxvalue[i+1].value]
tmpARR.push(tmp);
i+=2;
}
} else {
i++;
}
}
console.log(tmpARR);
return false;
}
The error is in "guardarNumeros" function because getElementsByClassName returns a collection and collection does not have a "value" property.
try this code
function guardarNumeros() {
const inputs = [...document.getElementsByClassName('myInput')];
const inputNumberArr = inputs.filter(x => x.type === 'number');
// tmpARR = [];
for (let i = 0; i < inputNumberArr.length; i++) {
const element = inputNumberArr[i];
if (i % 2 === 0) {
tmpARR.push([element.value]);
} else if (tmpARR[tmpARR.length -1] instanceof Array) {
tmpARR[tmpARR.length -1].push(element.value);
} else {
tmpARR.push([element.value]);
}
}
return false;

I am trying to deploy my first javascript application, which is a Chrome extension.
This simply generates random passwords and stores it with the url of current active tab.
App runs fine on local but after deploying it to Chrome, I got this error:
Uncaught TypeError: Cannot read properties of null (reading 'length')
index.js:65 (anonymous function)
I am a beginner, so any kind of criticism about my code is highly appreciated.
Thank you so much.
function render() {

"action": {

}
I solved it.
I understand that (please correct me if I'm wrong)
if the local storage is empty, it does not return an empty array when parsed.
Apparently, when I do:
passwords = JSON.parse(localStorage.getItem("savedPasswords"))
passwords is no longer an array.
I instead use:
passwords.push(JSON.parse(localStorage.getItem("savedPasswords")))
But that just pushes a nested array inside passwords.
So I added a for loop, and used an if statement to address the initial error:
let locSavedPasswords = localStorage.getItem("savedPasswords")
if(locSavedPasswords !== null) {
for( var i = 0; i < (JSON.parse(locSavedPasswords)).length; i++){
passwords.push(JSON.parse(locSavedPasswords)[i])
}}
Initially, savedPasswords won't exist in localStorage, so localStorage.getItem('savedPasswords') will return null.
You then do JSON.parse(null), which doesn't immediately crash because null is first coerced to a string and becomes 'null' which is then JSON-parsed and turns back to null since the string with contents null is valid JSON.
But you then do .length on it and crash.
The solution is to handle the case where the item is not yet set and handle it like it was a JSON-stringified empty array. You can do so for example using the nullish coalescing operator ??:
let passwords = JSON.parse(localStorage.getItem("savedPasswords") ?? '[]')
Or, you can keep initializing it with [] as you did before but wrap the assignment with the actual value in a condition:
let passwords = []
const json = localStorage.getItem('savedPasswords')
if (json !== null) {
passwords = JSON.parse(json)
}
Personally, what I like to do for structured data in localStorage is something like this, which also handles the case that other things like invalid JSON somehow got stored there (without bricking the application):
let passwords = []
try {
const data = JSON.parse(localStorage.getItem('savedPasswords'))
if (Array.isArray(data)) passwords = data
} catch {}
I have JS code on a webpage that loads questions in from mysql db and displays the text . What happens is that it cuts off words at the end of the line and continues the word on the next line at the start. So all text across the screen starts/ends at the same point.
This seems to be the code where it displays the text.
For example the text will look like at the end of a line 'cont' and then on next line at the start 'inue'.
How do i fix this?

The website is on my local now but i can upload a screenimage if need be and the whole code of the webpage. Or is the issue in html?

I'm guessing that #question{ word-break: break-all; } is probably the culprit then? –
CB..yes that fixed it:)
I am struggling on how to make the result output into images like: image 1, image 2 so on... Is there way to store all those images in the javascript and then show them on the result?
Here's the script of what i am talking about, please bear with me, i am learning and i am not an expert.
function proRangeSlider(sliderid, outputid, colorclass) {
var x = document.getElementById(sliderid).value;
document.getElementById(outputid).innerHTML = x;
document.getElementById(sliderid).setAttribute('class', colorclass);
updateTotal();
}
var total = 0;
function updateTotal() {
var list= document.getElementsByClassName("range");
[].forEach.call(list, function(el) {
console.log(el.value);
total += parseInt(el.value);
});
document.getElementById("n_total").innerHTML = total;
}
$.fn.serializeObject = function()
{
var o = {};
var a = this.serializeArray();
$.each(a, function() {
if (o[this.name] !== undefined) {
if (!o[this.name].push) {
o[this.name] = [o[this.name]];
}
o[this.name].push(this.value || '');
} else {
o[this.name] = this.value || '';
}
});
return o;
};
$(function() {
$('form').submit('click', function() {
$(this).hide();
$('html, body').animate({
scrollTop: $("#anchor").offset().top
}, 500);
$("#result").empty().append(
"<ul>" + Object.entries($('form').serializeObject()).map(e => `<li>${e[0]}: ${e[1]}`).join("") + "</ul>");
$(".hidden-block").show();
return false;
});
});
$(document).ready(function(){
$("#reset").click(function(){
location.reload(true);
});
});

I'm not sure what you mean by 'image' here, but maybe you want to display the slider within div#result?
Your code has some issues. To educate and entertain 😊 I've created a minimal reproducable example, presuming that by 'image' you mean the actual sliders. It
does not use jQuery
does not use inline event handling
does use event delegation
uses data attributes to be able to pass some state values etc.
document.addEventListener(`change`, handle);
updateTotal();
function handle(evt) {
if (evt.target.dataset.inputstate) {
return displayResult(evt.target);
}
}
function displayResult(origin) {
proRangeSlider(origin, ...origin.dataset.inputstate.split(`,`));
let totalValues = [];
document.querySelectorAll(`[data-inputstate]`).forEach(range => {
const rangeClone = createClone(range);
totalValues.push(`<li><div>${rangeClone}</div><div>${
range.dataset.name}: ${range.value}</div></li>`);
});
totalValues.push(`<li><div><b>Total: ${
document.querySelector(`#n_total`).textContent}</b></div></li>`);
document.querySelector(`#result`).innerHTML = `<ul>${totalValues.join(``)}</ul>`;
}
function createClone(fromRange) {
const clone = fromRange.cloneNode();
clone.setAttribute(`value`, fromRange.value);
clone.id = ``;
clone.removeAttribute(`data-inputstate`);
return clone.outerHTML;
}
function proRangeSlider(origin, outputId, colorclass) {
origin.closest(`div`).querySelector(`#${outputId}`).textContent = origin.value;
origin.setAttribute('class', colorclass);
updateTotal();
}
function updateTotal() {
let total = 0;

But ... you meant to create an image from some number, ok. This snippet may help. It uses an image sprite for the numbers.
const createNumber = nr => {
const numbers = `zero,one,two,three,four,five,six,seven,eight,nine`
.split(`,`);
return [...`${nr}`]
.map(n => `<div class="number ${numbers[n]}"></div>`)
.join(``);
}
const example = nr => document.body.insertAdjacentHTML(
`beforeend`,
`<div class="example">${nr} => ${createNumber(nr)}</p>`);
example(1234567890);
example(233);
example(732);
example(1854);

I am dynamically adding new div's to a div container, the problem i'm facing is that the div is probably just a few pixels too big and therefore spawns a scrollbar that is pretty much useless, but with overflow: hidden; a little bit of the div gets cut off. I'm looking to make the div little bit larger in height, applying height: 100%; didn't work. This is how I'm creating the divs
function layerCreatorX(submission) { // creator for normal layers
let unique_id = uuidv4() // created unique IDs
let wrapDiv = document.createElement("div")
wrapDiv.id = "wrapDiv" + unique_id
let activeLayerIcon = document.createElement("IMG")
activeLayerIcon.setAttribute("class", "activeLayerOff")
activeLayerIcon.setAttribute("name", "activeLayerIcon")
let invisibilityIcon = document.createElement("IMG")
invisibilityIcon.setAttribute("class", "visibilityButtonPos invisibilityButton") // filter for grey
invisibilityIcon.setAttribute("name", "invisibilityIcon")
let visibilityIcon = document.createElement("IMG")
visibilityIcon.setAttribute("class", "visibilityButtonPos visibilityButtonOff")
visibilityIcon.setAttribute("name", "visibilityIcon")
let line = document.createElement("hr")
line.setAttribute("style", "margin-top: 0px;")
line.className = "greyLine" //grey line will go underneath the div
let x = document.createElement("span")
let t = document.createTextNode(submission)
layerArray.push(unique_id)
layerNamesForComparison.push(submission) //new name comparator
x.className = "item item-layer"
x.id = unique_id
t.className = "noselect"
x.appendChild(activeLayerIcon)
x.appendChild(t)
x.appendChild(invisibilityIcon)
x.appendChild(visibilityIcon)
wrapDiv.appendChild(x)
wrapDiv.className = "LayerListDiv"
document.querySelector('.LayerList').appendChild(wrapDiv)
document.querySelector('.LayerList').appendChild(line)
}
and this is how they look when I create them:
I want to get rid of the vertical scrollbar on the right but still be able to view the whole div, if I use overflow hidden, the <hr> line from the bottom gets cut off and I can't see it anymore.
.LayerList CSS:
.LayerList {
user-select: none;
overflow: auto;
right: -15px;
width: 100%;
max-height: calc(93% - 60px); /*This height has to stay*/
}

I need script for file attachment in HTML input type file. While files attached in input file then have to show the file names also show the remove file button option beside the file name. Then add more file button option with multiple file attachment need.
