im trying to start the project

My site shows users their results on a quiz. The results are returned from a SQL database.
I have confirmed that the data is being returned correctly and as the correct type (integer).
The text fields are being added as expected however for the percentage bar (user’s score), only the first one loads correctly.

My code in php file:

  $(document).ready(function() {
    $width = $("#myResultBar").data('width');
    $("#myResultBar").css("width", $width + "%");
  });
  </script>

My and <?php code that only does the first display with percentage bar correctly:

<?php
  for($i = 0; $i < count($life_ins_quiz_chapter_num); $i++){
?>
      <!-- results box -->
      <div class="result_box">
        <h3 class="hd text-center">Chapter: <?php echo $life_ins_quiz_chapter_num[$i];?></h3>
        <p><?php echo $life_ins_quiz_chapter_desc[$i];?></p>
        <div class="row align-items-center">
          <div class="bar_main col-sm-11 col-9">
            <div id="mySaving" class="bar">
              <div id="mySavingBar" data-width="<?php echo $life_ins_quiz_chapter_pct[$i];?>"></div><!--problem here-->
            </div>
          </div>
          <div class="percent col-sm-1 col-3">
**            <!--This only shows up the first time. What am I doing wrong?-->**
            <?php echo $life_ins_quiz_chapter_pct[$i]; ?> %
          </div>
        </div>
        <div class="box_analysis">
          <h3>Question Score: <?php echo "[ " . $life_ins_quiz_chapter_score[$i] . "/6 ]"; ?> </h3>
          <?php //echo $saving_report_detail; ?>
        </div>
      </div>
<?php
  }//end for
?>

I have:
1-Done multiple checks to get the correct data type into that variable gettype(variable) = integer
2-Could not figure out if there was a way to change something in the js to have it increment the id
(for e.g. #MySavingBar_1(2,3)etc..

Open to any guidance or suggestions.

I have 3 inputs: an array, a total count integer and an arbitrary value.

input_array = ['hello', 'there', 'world']
total_count = 15
fill_value = null

Desired output:

output = [
  'hello',
   null,
   null,
   null,
   null,
   'there',
   null,
   null,
   null,
   null,
   'world',
   null,
   null,
   null,
   null,
]

Assume that the length of input_array does not exceed total_count. Other scenarios:

• If total_count was 3, you’d get ['hello', 'there', 'world']
• If total_count was 4, you’d get ['hello', null, 'there', 'world']
• etc. etc.

This feels like a candidate for a recursive function? You could take Math.ceil((total_count - input_array.length) / input_array.length) and use that value to fill in the slots but I’m not sure what the cleanest syntax would look like.

I would like to run a script in the browser console that will open an array of url’s one by one with a few seconds delay between them, better if in the same tab, will copy some data from the page and will insert it into a file and download it after finishing the url’s.
This is what I got so far, but still not working.
Do you know of any alternative to get the this result?

Thanks for the answers.

I am trying to use Nuxt Content to create a blog section of my website. I have created the directory structure and some testing posts. I have also created the query that grabs the posts and stores them as a ref so they can be used on the page. My issue is that the components I see on the page do not match what is returned by the Nuxt Content query

Snippet

<script setup> 
const { data: recentBlogPosts } = await useAsyncData(`content-${path}`, () => {
  return queryContent()
    .only(['title', 'excerpt', 'created', 'updated', 'slug', 'tags', '_id'])
    .limit(5)
    .sort({ 'updated': -1 })
    .find()
})

index.vue Page Snippet

<nuxt-link v-for="post in recentBlogPosts" :key="post._id" :to="`blog/${post.slug}`">
  <BlogPostShort class="blog-post-short"
    :title="post.title"
    :createdDate="post.created"
    :updatedDate="post.updated"
    :excerpt="post.excerpt"
    :tags="post.tags" />
</nuxt-link>

The resulting website output on the page

An image of Vue DevTools showing only 5 components produced by v-for directive

I have tried adding a :key="post._id" to the code but that hasn’t solved anything. I thought giving Nuxt a means of tying a post to the data on the backend might help it but sadly no such luck

I’m evaluating Axios and one thing I can’t seem to figure out how to enforce that a response is JSON. From what I’ve gathered, Axios will automatically parse the JSON for us based on the content type (https://stackoverflow.com/a/65976510/1103734). However, I was hoping to actually enforce that the response is JSON (e.g. if my nginx proxy returns HTML due to a downstream error, I would want to handle that).

I noticed that the Axios request config has a responseType property, but as near as I can tell, this is not used to actually enforce an expected type is returned. Here’s an example snippet that demonstrates what I’m talking about

axios.get('http://cataas.com/cat?html=true', {responseType: "json"})
  .then(res => console.log(`Response:n ${res.data}`))
  .catch((err) => console.log(`Error: ${err}`))

Output:

Response:
 
                <!DOCTYPE html>
                <html lang="en">
                    <header>
                        <meta charset="utf-8">
                    </header>
                    <body>
                        <img alt="GRxZb4kUHleQ3LhC" src="/cat/GRxZb4kUHleQ3LhC">
                    </body>
                </html>

The best thing I can find is to put JSON.parse in the transformResponse property, but this means that if there’s an error in parsing a response with a bad status code, I will lose that status code information in my catch.

axios.get('http://cataas.com/cat?html=true', {responseType: "json", transformResponse: JSON.parse})
  .then(res => console.log(`Responsen ${res.data}`))
  .catch((err) => console.log(`Error: ${err}`))

Output (obviously, SyntaxError does not contain any information about the response):

Error: SyntaxError: Unexpected token < in JSON at position 17

Is there a nice way to achieve what I want?

I’m trying to zoom in/out while scrolling down/up using ScrollMagic, currently, while I try to scroll down to zoom in on the image, it works, but after it’s completely zoomed in, trying to scroll up to zoom out has no effect, how to fix the problem? I’ve tried various approaches but can’t get this to work, someone please help!

I’m using javascript and here is the problem statement

const sourceArray = [3, 6, 9]

const elementsToGenerate = 10

expected output is random numbers from sourceArray till the length of the output array is 10 and should have at least 1 of each element from sourceArray and should be spread almost evenly

example output 1 [3,9,6,6,3,9,6,3,3,9]

example output 2 [9,6,3,9,6,9,3,9,3,6]

I’m trying to route the user on login to a page depending on data I get from a useQuery call , but the onSuccess is too quick to run while the query hasn’t fetch yet , my code looks like this

  const { data, refetch } = useQuery(["tracks"], getTracks, {
    enabled: false,
  });

  const { mutate, isLoading, isError, error } = useMutation(login, {
    onSuccess(d, v, c) {
      Cookies.set("cookieToken", d?.access);

      let type = Cookies.get("cookieToken");
      type = parseJwt(type);
      type = type.user_type;
      refetch();

      if (data) {
        if (type === 5 || type === 6) {
          navigate(`/${data?.object[0]?.id}?type=prio`);
        } else {
          navigate(`/${data?.object[0]?.id}?type=filtering`);
        }
      }
    },
  });

I want to onSuccess of the use mutation to fetch the query , wait for the result and navigate the user based on the data I get from the query , how to do so ?

I can’t run the useQuery before the onSuccess because it won’t succeed without having the token from the mutation

As a beginner with basic knowledge of HTML and JavaScript, what are some ways to improve my skills in JavaScript and learn Python?

I’m currently following online courses like Skillshare, but I feel like the learning experience would be more engaging and creative if I could test my own coding skills instead of just reproducing pre-made projects. Are there any resources or platforms that allow for more interactive and hands-on learning?”

I have a question about javascript within Jinja2 before I start on my project, so I can understand if jinja is the right solution to use

• I want to create an html email template that will fill in some values for each user, and then send them the rendered template via email. I already have the email functionality set up

• I want to include some charts from chart.js on the page, but because JS isn’t allowed on emails I have to convert the charts to images before sending the email.

My question is, does jinja allow for this to happen when rendering the template? Can I make sure that the charts are converted to images when the template is rendered, and all JS is removed/inactive before sending the template?

Assume a document on Firebase Firestore representing a house

{
  id: "1234",
  owner: "John",
  address: "123 Something Ave.",
  residents: [],
}

I have a cloud function that is supposed to add residents to the house.
Also note: the residents field isn’t always there from the start. Idea is to add it when the first resident is added.

This is my operation, which is part of a cloud function:

db.collection("houses")
      .doc(house_id)
      .set(
        {
          residents: admin.firestore.FieldValue.arrayUnion({
            uid: context.auth.uid,
            first_name: driverData.first_name,
            last_name: driverData.last_name,
          }),
        },
        { merge: true }
      );

But instead of creating this field with the array an leaving all the other data in the document, the function completely removes all the other data and I am only left with the residents array field.

Why is that?

I was trying to use my model to display and find users from the MongoDB,
But when I import it into profile.js and start my App it gives me an Error saying

• Cannot read properties of undefined (reading ‘Users’)
  

Note I Tried using it with the API and It works fine, Idk why it’s like this with my Component,
It’s weird to me because I never had this Error before, Anyone know how to fix it or why it’s showing this Error?

My code

connect.js

import mongoose from "mongoose";

export default async function connect(){
    try{
        const {connection} = await mongoose.connect(process.env.MONGODB_URL)
        if(connection.readyState = 1){
            return Promise.resolve(true)
        }
    }catch(err){
        return Promise.reject(err)
    }
}

user.js

import {Schema, models, model} from "mongoose";

const usersSchema = new Schema({
    ...
})

const Users = models.Users || model('Users', usersSchema)
export default Users

profile.js

import { useState, useEffect } from 'react'
import {signOut, useSession} from 'next-auth/react'
import connect from "@/database/connect"
import Users from "@/database/schema/users"
export default function Profile(){
    const [loaded, setLoaded] = useState(false)
    useEffect(() => {
        setLoaded(true)
    }, [])

    const {data: session} = useSession()
    console.log(session)
    useEffect(() => {
        const userSession = session.user?.email
        if(session){
            const checkUserInfo = async() => {
                const findUser = await Users.findOne({ email: session.user?.email })
                console.log(findUser)
            } 
            checkUserInfo()  
        }
    }, [])
}

When I run:

npm run dev

I get those 36 Errors saying wierd text no one faced it before
starting with this:

C:Windowssystem32cmd.exe [15836]: c:wssrcmodule_wrap.cc:599: Assertion `(it) != (env->id_to_function_map.end())' failed.

I searched for 3 days and found nothing!
This is the error in cmd
This is my package.json file
I struggled founding the solution!

Ran this command

npm run dev

I expected it to run the server for my next.js project

and this is the error it shows

`C:Windowssystem32cmd.exe [15836]: c:wssrcmodule_wrap.cc:599: Assertion `(it) != (env->id_to_function_map.end())' failed.

How to create the image gallery with N number of images to show to user to select in the app form in react js app ? So ,once user click’s the ‘open gallery button’ in the app form, user can view the image gallery to select one and upload in the app.(like wtsup emoji’s gallery)(we need to store all the gallery images inside the app itself)
