I have the following C# code to generate pre-signed URLs, and it works (client is an AmazonS3Client object):

        public static string GetPreSignedURL(string filename, string displayFilename)
        {
            GetPreSignedUrlRequest request = new();

            request.Verb = HttpVerb.PUT;
            request.BucketName = BucketName;
            request.Key = filename;
            request.Expires = DateTime.UtcNow.AddHours(24);
            request.ContentType = "application/octet-stream";       //this is needed so we can upload using AJAX

            request.ResponseHeaderOverrides.ContentDisposition = "attachment; filename=" + displayFilename;

            return client.GetPreSignedURL(request);
        }

Now I have Jquery to make the PUT request:

                    $.ajax(
                    {
                        url: response1.preSignedURL,
                        type: 'PUT',
                        data: file,
                        processData: false,
                        contentType: "application/octet-stream",
                        success: function(response)
                        {
                            console.log(JSON.stringify(response));
                        }
                    });

It works fine. However if I remove application/octet-stream from the URL generator and the AJAX code, I get a dreaded SignatureDoesNotMatch error.

It would be nice to be able to remove the Content-Type header as it seems a bit hacky.

Getting an error on stackoverflow when running any snippet on chromium browsers (tested on chrome and edge) it is working on firefox though.

(index):1  Refused to display 'https://stacksnippets.net/' in a frame because it set 'X-Frame-Options' to 'sameorigin'.

console.log("stacksnippets.net refused to connect");

I want the website to be fullscreen on iOS 26 so that there’s no background behind the search bar. I want it to be floating over the website, like the screenshot from appleparts.nl below. The other screenshot below is mine.

I want the search bar to be transparent. I tried to make the color transparent, but it didn’t work.

If I’m on the top of the page, there’s nothing, but if I scroll and the navbar goes away, it shows up.

This is the code of the navbar. I thought it was the theme color, but it isn’t. I don’t know how I get the section behind.

const ruler = document.getElementById('ruler');
const indicator = document.getElementById('indicator');

// Genereer ticks zoals bij een meetlat (elke 10e langer)
const totalTicks = 150;
for (let i = 0; i < totalTicks; i++) {
    const tick = document.createElement('div');
    tick.classList.add('tick');
    if (i % 10 === 0) tick.classList.add('long');
    ruler.appendChild(tick);
}

let activeIndex = 0;

function moveTo(index) {
    const link = links[index];
    const linkRect = link.getBoundingClientRect();
    const parentRect = link.parentElement.getBoundingClientRect();

    const centerOffset = linkRect.left - parentRect.left + linkRect.width / 2;

    ruler.style.transform = `translateX(${centerOffset - ruler.offsetWidth / 2}px)`;
    indicator.style.left = `${centerOffset}px`;

    links.forEach(a => a.classList.remove('active'));
    link.classList.add('active');
}

// Hover functionaliteit
links.forEach((link, index) => {
    link.addEventListener('mouseenter', () => moveTo(index));
    link.addEventListener('click', () => {
        activeIndex = index;
        moveTo(index);
    });
});

document.querySelector('.nav-links').addEventListener('mouseleave', () => {
    moveTo(activeIndex);
});

// Init bij laden van pagina
window.addEventListener('load', () => {
    const path = window.location.pathname;

    links.forEach((link, index) => {
        const href = link.getAttribute('href');
        if (path.endsWith(href)) activeIndex = index;
    });

    moveTo(activeIndex);
});

// Hamburger & mobiel menu
const hamburger = document.getElementById('hamburger');
const mobileMenu = document.getElementById('mobileMenu');
const mobileLinks = mobileMenu.querySelectorAll('a');
const desktopLinks = document.querySelectorAll('.nav-links a');

let scrollPosition = 0;

function openMobileMenu() {
    hamburger.classList.add('opened');
    hamburger.setAttribute('aria-expanded', 'true');
    mobileMenu.classList.add('open');

    // Body scroll blokkeren
    scrollPosition = window.scrollY;
    document.body.style.position = 'fixed';
    document.body.style.top = `-${scrollPosition}px`;
    document.body.style.left = '0';
    document.body.style.right = '0';
    document.body.style.overflow = 'hidden';
}

function closeMobileMenu() {
    hamburger.classList.remove('opened');
    hamburger.setAttribute('aria-expanded', 'false');
    mobileMenu.classList.remove('open');

    // Body scroll weer toestaan
    document.body.style.position = '';
    document.body.style.top = '';
    document.body.style.left = '';
    document.body.style.right = '';
    document.body.style.overflow = '';

    // Scroll terugzetten naar vorige positie
    window.scrollTo(0, scrollPosition);
}

hamburger.addEventListener('click', () => {
    if (hamburger.classList.contains('opened')) {
        closeMobileMenu();
    } else {
        openMobileMenu();
    }
});

// Menu sluiten bij klikken op link in mobiel menu + active class bijhouden
mobileLinks.forEach((link, index) => {
    link.dataset.index = index;
    link.addEventListener('click', () => {
        closeMobileMenu();

        // Active class mobiel
        mobileLinks.forEach(l => l.classList.remove('active'));
        link.classList.add('active');

        // Active class desktop
        desktopLinks.forEach(dl => dl.classList.remove('active'));
        desktopLinks[index].classList.add('active');

        // Update activeIndex
        activeIndex = index;
        moveTo(activeIndex);
    });
});

// Bij resize: sluit mobiel menu bij desktop & zet scroll aan
window.addEventListener('resize', () => {
    if (window.innerWidth > 900) {
        closeMobileMenu();
    }
});

I’ve tried setting the theme color to transparent, but that didn’t work.

I was iterating over an object in JavaScript and noticed a difference between for…in and Object.keys().

const parent = { inheritedProp: "hello" };
const child = Object.create(parent);
child.ownProp = "world";

// Using for...in
for (let key in child) {
  console.log(key);
}

// Using Object.keys
console.log(Object.keys(child));

Output:

for…in: inheritedProp, ownProp
Object.keys: ownProp

Why does for…in iterate over inherited properties, while Object.keys() only returns the object’s own properties? Is there a specific reason for this behavior in JavaScript?

I have a problem with a client’s website. The html is served fine when the user-agent is a browser, however, the page is not passing online html validation because the server is injecting some javascript code just before the !DOCTYPE tag. If I use wget to download the page I can see the injected stuff. Here it is:

<script>console.log('[PHP] session begin ENDS - 0 ms');</script>
<script>console.log('[PHP] autologin denied ends - 0.013 ms');</script>
<script>console.log('[PHP] bot check ENDS - 0.277 ms');</script>
<script>console.log('[PHP] autologin ENDS - 0.282 ms');</script>
<script>console.log('[PHP] user id forced to be integer ENDS - 0.867 ms');</script>
<script>console.log('[PHP] suser banned ENDS - 0.98 ms');</script>
<script>console.log('[PHP] if bot assign previous session ENDS - 0.985 ms');</script>
<script>console.log('[PHP] screate new session ENDS - 1.004 ms');</script>
<script>console.log('[PHP] deal with no last page ENDS - 2.297 ms');</script>
<script>console.log('[PHP] regenerate autologin ends - 2.301 ms');</script>
<script>console.log('[PHP] refresh data ends - 431.357 ms');</script>

The client wants this removed but I have no idea where this is coming from (some Apache/php module? a hack?). Any ideas?

I tried inspecting .htaccess, but there’s nothing suspicious there.

In span I have number and try to inner text for my test and I can’t do it. I need to check I have 0 or another count of staff and I don’t see result of num_basket in console

<span class="basket-count-items badge badge-primary">1</span>

const num_basket = await page.locator('.basket-count-items.badge').textContent()
 console.log(num_basket)
 if (num_basket !== 0) {await page.locator('//a[@id="dropdownBasket"]').click()
 await page.locator('.btn.btn-danger').click()}

How I can inner text?

Sorry, I couldn’t find a suitable title for this topic.

I have a script ready and it works fine. What I want to do is add a color switcher to the site and change the background canvas color. I change the code below and add the necessary css tags, but when I click, only the color changes and the sliding canvas in the background does not appear. What am I doing wrong?

enter image description here

<h3 class="text-white">Color Switcher</h3>
<li class="purple" onclick="draw('purple')"data-bs-toggle="tooltip" data-path="css/color-purple.css"></li>

I want the website to fullscreen on iOS 26 so there’s no background behind de search bar so it’s floating over the website like the foto from appleparts.nl the other is mine.

I want that the searchbar is transparent. I did try to make the color transparent but it didn’t work.

If I’m on the top of the page there’s nothing but if I scroll and the navbar goes away it comes

[website where the bar is under the searchbar]

image where it isnt this is what i want

this is the code of the navbar i thought it was the theme color but it inst i dont know how i get the section behind

I was iterating over an object in JavaScript and noticed a difference between for…in and Object.keys().

const parent = { inheritedProp: "hello" };
const child = Object.create(parent);
child.ownProp = "world";

// Using for...in
for (let key in child) {
  console.log(key);
}

// Using Object.keys
console.log(Object.keys(child));

Output:

for…in: inheritedProp, ownProp
Object.keys: ownProp

Why does for…in iterate over inherited properties, while Object.keys() only returns the object’s own properties? Is there a specific reason for this behavior in JavaScript?

I have a problem with a client’s website. The html is served fine when the user-agent is a browser, however, the page is not passing online html validation because the server is injecting some javascript code just before the !DOCTYPE tag. If I use wget to download the page I can see the injected stuff. Here it is:

<script>console.log('[PHP] session begin ENDS - 0 ms');</script><script>console.log('[PHP] autologin denied ends - 0.013 ms');</script><script>console.log('[PHP] bot check ENDS - 0.277 ms');</script><script>console.log('[PHP] autologin ENDS - 0.282 ms');</script><script>console.log('[PHP] user id forced to be integer ENDS - 0.867 ms');</script><script>console.log('[PHP] suser banned ENDS - 0.98 ms');</script><script>console.log('[PHP] if bot assign previous session ENDS - 0.985 ms');</script><script>console.log('[PHP] screate new session ENDS - 1.004 ms');</script><script>console.log('[PHP] deal with no last page ENDS - 2.297 ms');</script><script>console.log('[PHP] regenerate autologin ends - 2.301 ms');</script><script>console.log('[PHP] refresh data ends - 431.357 ms');</script>

The client wants this removed but I have no idea where this is coming from (some Apache/php module? a hack?). Any ideas?

I tried inspecting .htaccess, but there’s nothing suspicious there.

I have an interview coming up for the Microsoft leap software engineer program and was wonder if anyone can offer any advice about what I should study or expect?

Any information and advice would be appreciated.

I’m expecting string related questions but I am not sure what to expect. This is all new for me.

In span I have number and try to inner text for my test and I can’t do it. I need to check I have 0 or another count of staff and I don’t see result of num_basket in console

<span class="basket-count-items badge badge-primary">1</span>

const num_basket = await page.locator('.basket-count-items.badge').textContent()
 console.log(num_basket)
 if (num_basket !== 0) {await page.locator('//a[@id="dropdownBasket"]').click()
 await page.locator('.btn.btn-danger').click()}

How I can inner text?

I tried to pass String from javascript to java. And In java code it has some operations. but it give error.

const inputStrPointer = createTeaVMString(input);
const outputStrPointer = teaVM.instance.exports.process(inputStrPointer);
const result = extractString(outputStrPointer);

here the createTeaVMString is like this,

function createTeaVMString(input) {
const strPointer = teaVM.allocateString(input.length);
const strDataPtr = teaVM.stringData(strPointer);
const charArrayPtr = teaVM.objectArrayData(strDataPtr);
const memory = new Uint16Array(teaVM.memory.buffer, charArrayPtr, input.length);
for (let i = 0; i < input.length; i++) {
memory[i] = input.charCodeAt(i);
}
return strPointer;
}

and the exactTeaVMString is like this,

function extractString(strPointer) {
//pointer
    const stringDataPtr = teaVM.stringData(strPointer);
    const length = teaVM.arrayLength(stringDataPtr);
    const charArrayPtr = teaVM.charArrayData(stringDataPtr);
    const memory = new Uint16Array(teaVM.memory.buffer, charArrayPtr, length);
    let result = "";
    for (let i = 0; i < length; i++) {
        result += String.fromCharCode(memory[i]);
    }
    return result;
}

But in the java code,

@Export(name = "process")
public static String process(String input) {

    return new StringBuilder(input).reverse().toString();

}

@Export(name = "type")
public static String type(String input) {
    return  input.toString().getClass().getSimpleName();
}

First process function is working, but second one is not(type).
And I tried lots of these kind of functions. I tried to look references but there are no any references. Then by using AI it tells that js String is not fully converted to java String.

I’m building a PHP page with multiple tabs (Termijnen, Mandaten, and Admin). Each tab’s content is pre-rendered by PHP inside hidden <div> elements. I then inject the content into a visible container (#tab-content) using jQuery when a tab is clicked.

Here’s the structure of my HTML:

                default => 'bg-light text-dark',
            };

The tabs themselves are buttons:

<div class="button-group" role="group">
    <button class="btn btn-sm btn-outline-primary active" data-tab="termijnen">Termijnen</button>
    <button class="btn btn-sm btn-outline-primary" data-tab="mandaten">Mandaten</button>
    <button class="btn btn-sm btn-outline-secondary" data-tab="admin">Admin</button>
</div>

JavaScript to load tabs:

function loadTab(tab) {
    const content = $(`#content-${tab}`).html();
    $('#tab-content').html(content);

    if (window.feather) feather.replace(); // for icons
}

I also have search, pagination, and dynamic modals for editing IBANs, pausing mandates, linking mandates to termijnen, etc.

Problem

• The hidden for Termijnen exists ($(‘#content-termijnen’).length === 1) and contains HTML, but is not visible in the #tab-content container when expected.
• The hidden s for Mandaten and Admin currently do not exist in the DOM at all when inspected with jQuery ($(‘#content-mandaten’).length === 0).
• Console logs show that the Termijnen HTML exists, but it does not render initially.
• Mandaten only exists dynamically if a button is clicked that makes it active.
• A simple console.log(‘Hello world’); works, so scripts run, but the tab content injection does not appear as expected.
• All libraries (jQuery, Bootstrap, Feather) are loaded, and no JS errors are present.

Question

1. Why does content from hidden <div>s sometimes not render when injected into #tab-content, even though the <div> exists and has HTML?
2. How can I reliably load all tab content immediately on page load or on tab click, so that the dynamic cards, modals, and icons work correctly without requiring extra user interaction?

I tried to render the hidden tab content <div>s (#content-termijnen, #content-mandaten, and #content-admin) into the main container #tab-content using jQuery when the page loads or when a tab button is clicked.

• I verified that $('#content-termijnen').length === 1 and it contains HTML, so I expected it to appear inside #tab-content on page load.
• I also verified that console.log('Hello World') in a separate <script> tag works, proving that scripts execute.
• I expected the Termijnen tab to load automatically, and Mandaten/Admin tabs to populate when their respective buttons are clicked.

Actual results

• Termijnen HTML exists in the DOM but does not appear in #tab-content, so the content is invisible.
• Mandaten and Admins are 0 in length initially and do not appear at all.
• No JavaScript errors occur, and libraries like jQuery and Feather are loaded initially.

I am using editor js but i will not come with default parser.

The editor js output is raw json which is easy to parse but needs to create multiple html element.

If anyone created editorjs parser with styles or only raw html please provide me.

I am working with javascript only no framework here…
