Iam learning programming fundamental {web programming} at udacity website….
The question

when I answer the error tha popup

here my question:-

when I answered ‘https://developer.mozilla.org/en-US/docs/Web/API/Document/createElement’

to the question with ” What is the URL for the “createElement” page on MDN?”

he answered me with “Do a search for the “createElement” page on MDN. Then submit the URL for that page.

Also, make sure you submit the complete URL”,

whats the problem….this is my question

So who can help me? I need your help to finish my assessment

I’ve been banging my head at this problem for a few days now. I can’t figure out why the layout of this isn’t working with proper z-index values.
The CSS has strange interactions.

The dark overlay goes over everything except the logo image. The menu goes over the header and I want both to go under the header.

I tried to make the menu and overlay go under the header. They won’t and stay on top.

// Get the elements
const hamburgerButton = document.querySelector(".ham_menu"); // The hamburger button
const menu = document.querySelector(".off_screen_menu"); // The hamburger menu
const overlay = document.querySelector(".overlay"); // The overlay

// Toggle the hamburger menu
hamburgerButton.addEventListener("click", (event) => {
  event.stopPropagation(); // Prevent the click from bubbling up
  menu.classList.toggle("active"); // Toggle the menu open/close class
  overlay.classList.toggle("active"); // Show/hide the overlay
  hamburgerButton.classList.toggle("active"); // Toggle hamburger button animation
});

// Close the hamburger menu if clicked on the overlay
overlay.addEventListener("click", () => {
  menu.classList.remove("active");
  overlay.classList.remove("active");
  hamburgerButton.classList.remove("active"); // Reset the hamburger animation
});

I’m using a laptop which has x64-based processor and runs on 64-bit operating system i.e. Windows 10 Home Single Language

I’m a complete newbie to the things called Node.js, Fast Node Manager (fnm) and WindowsPowershell.

In order to install Node.js on my laptop I went to the Download page of the official Node.js website. The screenshot of this Download page is as below :

I opened the WindowsPowershell on my laptop and followed the first two instructions mentioned in above picture and everything worked smoothly but as soon as I typed the third instruction i.e. node -v I got the below error and not able to check the version of Node.js installed on my laptop.

node : The term 'node' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
At line:1 char:1
+ node -v
+ ~~~~
    + CategoryInfo          : ObjectNotFound: (node:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException

The relevant screenshot of WindowsPowershell is as below :

I’ve a node.exe file located at C:UserslenovoAppDataRoamingfnmnode-versionsv22.13.1installationnode.exe

Can someone please help me in this regard in chechking the version of Node.js installed on my laptop and running it?

P.S. : Please don’t suggest me to use the Node.js installer for Windows to install Node.js on my laptop.

I tried to solve problem through ai and used loop to control rows but all in vein.
Problem is that I have a platform to work in which I need to calculate and calculating manually is so much tiring so I created code in python which works well as I want but I want to show it graphically so I changed code to JavaScript to show in table unlike in lists of python but this create resulte for 11 rows but I need minimum 50 rounds
**In other words I need calculation which will show me what to add next from round one to 50 in form of table.
Table include profit, amount in per round,total in all round,round no. **

I tried below html code and wanted to get resulte of python code which is in end I summarize form through html.

I am trying to copy all messages between me and ChatGPT-4o to a text file in Firefox’s Developer Tools.

Here is what I got so far:

const prompts = $x("//div[@class='whitespace-pre-wrap']");
const replies = $x("//div[contains(@class, 'markdown prose')]");
const messages = [];

for (let i = 0; i < prompts.length; i++) {
    messages.push(["Ξένη Γήινος", prompts[i].textContent]);
    messages.push(["ChatGPT", replies[i].textContent]);
}
console.log(JSON.stringify(messages))

I then expand the output and right click to copy the message.

It works, but it doesn’t do exactly what I wanted. I want the text to be exactly as rendered on screen, the output should be as if I copy-pasted the text. .textContent doesn’t preserve the format.

For example, given this thing:

I want the output to be like this:

You're correct about the number of characters in your earlier sentence; I miscounted the total. I appreciate your patience.

Regarding the Python code you've provided:

print(sum(i.isalpha() for i in "How many Latin characters are there in this sentence?"))

This code will count only the alphabetic characters in the string, ignoring punctuation and spaces.

Let's break it down:

    "How many Latin characters are there in this sentence?"
        Letters: H, o, w, m, a, n, y, L, a, t, i, n, c, h, a, r, a, c, t, e, r, s, a, r, e, t, h, e, r, i, n, t, h, i, s, s, e, n, t, e, n, c, e

The total count of alphabetic characters (Latin characters) in this sentence is 44.

Thus, running the code would output 44.

The output is exactly the same as the result of copy-paste (because I copy-pasted it).

Result of .textContent:

`You're correct about the number of characters in your earlier sentence; I miscounted the total. I appreciate your patience.Regarding the Python code you've provided:pythonCopyEditprint(sum(i.isalpha() for i in "How many Latin characters are there in this sentence?"))
This code will count only the alphabetic characters in the string, ignoring punctuation and spaces.Let's break it down:"How many Latin characters are there in this sentence?"Letters: H, o, w, m, a, n, y, L, a, t, i, n, c, h, a, r, a, c, t, e, r, s, a, r, e, t, h, e, r, i, n, t, h, i, s, s, e, n, t, e, n, c, eThe total count of alphabetic characters (Latin characters) in this sentence is 44.Thus, running the code would output 44.`

The format is broken.

I tried to write a simple recursive function to mimic the result of copy-paste, but it doesn’t work:

function flatten(x) {
  let text, children;
  children = x.children;
  if (children.length) {
    text = flatten(children[0])
    for (let i = 0; i < children.length; i++) {
      text += "n" + flatten(children[i]);
    }
    return text;
  }
  return x.textContent;
}

Simply put the output is garbage.

How can I copy all text of an element including all sub-elements (and their sub-elements…) while preserving the formatting?

Please I am having issues implementing signal protocol, like the creation of prekey, registering to server, fetch prekey bundle, and encrypting is not an issue, but decrpting is where the challenges begin.

Here’s the scenario:

1. Initial Setup:

   • Alice and Bob both register on the server and upload their pre-key bundles.
   • Alice sends the first message to Bob using Bob’s pre-key bundle to encrypt it.

2. Problem on Bob’s Side (First Issue):

   • Bob receives the encrypted PreKeyWhisperMessage but fails to decrypt it.
   • The following error is thrown:

     [Error: Missing Signed PreKey for PreKeyWhisperMessage]
     

   • Note: Bob has not sent any message to Alice before this.

3. Problem on Alice’s Side (Second Issue):

   • After Bob encounters the above error, if Bob then sends a message to Alice, Alice throws this error when trying to decrypt the message:

     [Error: unable to find session for base key BX+cGz/mCJDPm2R4bJ7ggHzaX8gCBLOZN5Z6VZSxs+hO, 33]
     

   • This error seems to indicate that Alice cannot find a session for the baseKey from Bob.

4. Observations:

   • On Bob’s device, before encrypting, I can see the baseKey in the cipher object.
   • However, when I inspect the cipher object on Alice’s device after the error occurs, I cannot find the baseKey in the session or storage.
   • Here’s a sample log of the cipher from Alice’s side during decryption:

     {"encryptJob": [Function anonymous], "fillMessageKeys": [Function anonymous], "loadKeysAndRecord": [Function anonymous], ...}
     

     The baseKey (BX+cGz/mCJDPm2R4bJ7ggHzaX8gCBLOZN5Z6VZSxs+hO) is missing, which seems to align with the error message.

5. Questions:

   • Why is the “Missing Signed PreKey for PreKeyWhisperMessage” error occurring on Bob’s device for the first message from Alice?
   • Why does Alice then throw the “unable to find session for base key” error when trying to decrypt Bob’s response?
   • Is there a fundamental step I’m missing, such as session setup or pre-key handling, especially when Bob hasn’t sent any message before?

please note: that I am using the modify version of this storage src/test/storage-type.ts but integrated with MMKV for persistence

I have a form with 5 fields to be filled out by the client, this data is stored in a spreadsheet with 5 columns that is already linked to the form, what I need to do is fill a 7th column in the same spreadsheet with data that is calculated according to the information received in the 4th column, I have a script which makes the calculation based on a condition, however the script is unable to fill column 7.

function onFormSubmit(e) { 
 var responses = e.values;

 var spreadsheet = SpreadsheetApp.getActiveSpreadsheet();
 var sheet = spreadsheet.getSheetByName('data');

 var lastRow = sheet.getLastRow();

 var responseValue = responses[4]; 

 var valueToAssign;
 if (responseValue === 'Yes') {
   valueToAssign = 'Approved';
 } else if (responseValue === 'No') {
   valueToAssign = 'Denied';
 } else {
   valueToAssign = 'Pending';
 }

 var lastColumn = sheet.getLastColumn() + 1;
 sheet.getRange(lastRow,lastColumn).setValue(valueToAssign);
}

the script already has the necessary permissions to make changes to the spreadsheet.
Am i missing something?

I have tried to specify the column number

var lastColumn = 7;

but the problem persists, column 7 remains empty.

I am trying to push data to local storage. What I have is basically what others but does not seem to work.

var data = {"fullname":data['name'],"picture":"<img src="+data['picture']+" />"}
var result = JSON.parse(localStorage.getItem("oauth2-test-params"));
result.push(data)

My object looks like this console.log(localStorage):

{
"picture": "two",
"fullname": "Junk",
"test-params": "{"three":"77-96L2N","four":"junk","five":"Bearer","expires_in":"3599"}"
}

I want to add picture and fullname to the test-params.
The code I have isn’t working and it is what everyone else is using.
I keep getting this error result.push is not a function

Given this HTML:

<svg id="svg" viewBox="0 0 100 10" version="1.1" xmlns="http://www.w3.org/2000/svg"></svg>

<svg id="wtf" viewBox="0 0 100 10" version="1.1" xmlns="http://www.w3.org/2000/svg">
    <g>
        <rect class="rect" x="0" y="0" width="100" height="100" fill="cyan"></rect>
    </g>
</svg>

And this JavaScript:

const group = document.createElement('g');
const string = `<rect class="rect" x="0" y="0" width="100" height="100" fill="pink"></rect>`;
group.innerHTML = string;
const svg = document.getElementById('svg');
svg.appendChild(group);

Why do I only see the second SVG and an empty space where the first should be? There should be two SVG elements containing the same group and rectangle, only differing by color.

Seems like I’m missing something obvious.

not sure how to go about it. I’m building this water usage calculator. When someone picks an activity (like watching YouTube or scrolling through TikTok) and enters how much time they spent on it, I want to calculate how much water was used for that activity. After the calculation, I want to show that amount in a visual representation of a 6 oz glass. If the water exceeds 6 oz, I want the image to show multiple glasses filled with the appropriate amount. I just need help with the visual water part.

html:

<label for="activity">Select an Activity:</label>
<input type="text" id="activity" placeholder="Start typing an activity..." autocomplete="off">

<label for="time">Enter time spent (in minutes):</label>
<input type="number" id="time" placeholder="Minutes">

<button onclick="calculateWaterUsage()">Calculate</button>

<div id="result"></div>

JavaScript:

// JavaScript code related to the issue
function calculateWaterUsage() {
  // Water usage calculations
  let waterUsage = 0;
  if (waterUsageRates[activity]) {
    waterUsage = (waterUsageRates[activity] * time) / 60; // Convert to minutes
  }

  // Water glass visualization logic
  const glassSize = 0.177; // 6 oz = 0.177 liters
  const fullGlasses = Math.floor(waterUsage / glassSize); // Full glasses
  const remainingWater = waterUsage % glassSize; // Remaining water for the last glass
  let glassHTML = '';

  for (let i = 0; i < fullGlasses; i++) {
    glassHTML +=
      '<div class="glass-container"><div class="water" style="height: 100%;"></div></div>';
  }

  if (remainingWater > 0) {
    const fillPercentage = (remainingWater / glassSize) * 100;
    glassHTML += `<div class="glass-container">       <div class="water" style="height: ${fillPercentage}%;"></div>     </div>`;
  }

  resultDiv.innerHTML = `   <br><strong>Water Usage Visualization:</strong><br>     ${glassHTML} `;
}

CSS:

/* CSS relevant to displaying the water glasses */
.glass-container {
width: 60px;
height: 120px;
border: 2px solid #000;
margin-right: 10px;
margin-bottom: 10px;
display: inline-block;
position: relative;
}

.water {
width: 100%;
background-color: #2196F3; /* Water color */
position: absolute;
bottom: 0;
}

Steps I’ve Taken So Far:

• I’ve got the visual for the 6 oz glass of water, using an image for the empty glass and a colored div to represent the water inside it.
• HTML: Created input fields for activity and time spent, along with a button to trigger the calculation.
• JavaScript: Written code to calculate the water usage for each activity based on predefined rates. The program is supposed to show the water usage visualization dynamically.
• CSS: Styled the glass container and the water inside the glass.

Issue:

• The empty glass image is displaying correctly.

• However, the water is not filling the glass as expected. Instead, a separate rectangle (colored blue) is showing up overlapping the glass, instead of filling the glass image itself.

  • example 1

    

  • example 2

    

What I was expecting:

The water level should dynamically update in the glass image based on the calculated water usage.
If the calculated water amount exceeds 6 oz, additional glasses should appear, with the water level adjusted accordingly.

I am new to this but yeah I want the water inside the glass image to dynamically fill up based on the calculation. Open to tips or differnt approaches

Hello guys i am new to using react so I’ve built a gallery application as a part of learning it but the image size is like 1mb to 15mb and it makes the site too laggy,

i tried compressing the images but they lost clarity even after that the site is still laggy what should i do?

When I focus on a text field I want to automatically switch to hiragana option in my Japanese Microsoft IME.

So far, I haven’t found anything about manipulating IME. I tried using ime-mode CSS property, but it seems they are no longer supported. I also tried making hiragana a default option but base on my searches I do not think this is achievable

I have a table called document_population with a column named “document_id”.
I want to query the table in Mulesoft (using Anypoint Studio) to return all rows with a document_id that matches any id in my array named “documentIDs” which might look like [123, 456, 789].

I am trying to use MySQL’s IN function, however, it cannot handle arrays, so it needs to be converted to a usable format.

Original attempt:

SQL Query Text:

SELECT * FROM document_billing WHERE document_id IN :documentIDs;

Input Parameters:

{
     "documentIDs": vars.documentIDs
}

Problem: SQL query syntax error

Attempted solution 1:

SQL Query Text:

SELECT * FROM document_billing WHERE document_id IN :documentIDs;

Input Parameters:

{
     "documentIDs": vars.documentIDs joinBy ","
}

Problem: Resulting SQL query looks like the following:
SELECT * FROM document_billing WHERE document_id IN ("123, 456, 789")
which returns rows with a document_id of “123, 456, 789” instead of rows with a document_id of 123, 456, or 789.

Attempted solution 2:

%dw 2.0
output application/java
var query = "SELECT * FROM document_billing WHERE document_id IN ("
---
query ++ (payload.documentIDs joinBy (",")) ++ ")"

SQL Query Text:

:document_billing_query;

Input Parameters:

{"document_billing_query": vars.document_billing_query}

Problem: Invalid query

Attempted solution 3:

%dw 2.0
output application/java
var query = "SELECT * FROM document_billing WHERE document_id IN ("
---
query ++ (payload.documentIDs joinBy (",")) ++ ")"

SQL Query Text:

#[$(document_billing_query)]

Problem: Invalid query

Attempted solution 4:

%dw 2.0
output application/java
var query = "SELECT * FROM document_billing WHERE document_id IN ("
---
query ++ (payload.documentIDs joinBy (",")) ++ ")"

SQL Query Text:

#["$(document_billing_query)"]

Problem: Invalid query
