I have this router:
// get your courses page

router.get('/yourcourses', async (req, res, next) => {
  let results = []
  if(req.user){
    for(let i =0; i<req.user.coursesFollowing.length; i++){
      let course = Course.findOne({ 'published': true, title: req.user.coursesFollowing[i].courseTitle, authorUsername: req.user.coursesFollowing[i].username }).exec(function (err, result) {
        if(err){return next(err)}
        results.push(result)
        console.log(results)
      })
    }
  }
  console.log(results)
  res.render('content', { whichOne: 1, user: req.user, courses: results});
});

I console log the result from the queries it seems to find the right documents, and when i console log the full array it seems okay,

however looking at the terminal I can see the computer prints the values after rendering the page, which means I need to use an async function to wait for the queries to end, however I am used to do it with one query, not multiple queries inside a loop, so how do I do that?

How do I wait until all the queries inside a loop are done before rendering the page? I tried using settimeout() however it is not predicting how much time it will take.
how would I fix this?

THANKS

I am trying to use an integration tool called Integromat (now know as Make) and they have a Text Parser option where I believe I can do what I want, but I am not sure how.

I am setting up a flow and have a webhook set up that receives a payload from another system. One of the fields in the payload is “website link”. It looks like this:

http://www.example.com and also like http://example.com

I want to remove the http:// and also the http://www. when it occurs and be left with the domain name.

I am not finding good search results for this problem as the company is named “make” so I get unintended results. I also looked through their docs and can’t find anything around string replacement that lines up with what I’m trying to do.

I’ve attached a screenshot if it helps show the text parser.

How i can draw on a given background image with a current jQuery Version and placing pins points which refer to a text-label (example image) and saving the new image with a save button?

Is it better to use existing plugins or using slim functions?

As the title already explains a lot of the problem,

I just developed a simple application in React Hook, my current routes are defined by

   <Router>
      <Routes>
        <Route exact path='/' element={<Home/>}/>
        <Route path='/products/:category' element={<ProductBrowsing/>}/>
        <Route path='/productsDetails/:id' element={<ProductDetails/>}/>
        <Route path='/login' element={<Login/>}/>
        <Route path='/register' element={<Register/>}/>
      </Routes>
    </Router>

testing all these routes in my local machine, it was possible to navigate in all pages either by calling the <Link> component or by putting directly through the URL

when I went to the process of deploying my application and putting it inside a VPS, I realized that a call by <Link> is passable unless the /:category attribute is not the same, which causes the page not to load even if the URL changes (and im passing a lot of parameters that doenst affect the page as a result of this), so the next solution imagined was to always refresh the page to force the component to load with the correct URL, but always when I try to refresh the page in my application I get an immediate response from the tag returning “You need to enable JavaScript to run this app.”

basically I can no longer navigate my application and im hopeful to know why

You can check this behavior here -> http://153.92.221.32/

by trying to navigate through the mega menu links inside the navbar and try to refresh the page, or simply change some subcategory inside the megamenu and notice that the URL changes and the components don’t.

I am developing an android app using react-native and i have a but of a struggle of figuring out why my component re-renders on each page navigation.

In my case i have created a wrapper component called Container.android.js

const Container = props => {
  useEffect(() => {
    // fetching some data from async storage
  },[])

  // Using my hook here
  const {code, error} = usePdaScan({ 
    onEvent: (code) => {
        // setting state via useState
    }, 
    onError: (error) => { 
        Alert.alert('Error', error); 
    }, 
    trigger: 'always'
  });

  return <View>
  {props.children}
  </View>
}

Then i declare routes with Stack.Screen where each stack uses a component wrapped with the Container component.

<Stack.Screen name="Overview" component={Overview} />

And my Overview compnent is this

const Overview = props => {
   return <Container>
        <Text>Overview page</Text>
   </Container>
}

My problem is that inside the Container component, there is a hook called usePdaScan. Each time i navigate to another page and the hook gets called, the Container component re-renders twice… I cant get a lead on this… Halp!

So I’m writing a webpage where the user inputs values into two textarea fields, and once they click on the submit button, the program is supposed to initiate a download of both text inputs and save them into a text file. So far, I’ve figured out how to have only one of the text inputs be saved to the text file, and I’ve been trying to figure out how to get my Javascript function to have this done for both text inputs. Here is my html and javascript code:

 <body>
      <label for="textbox">Textbox1</label>
      <textarea id="textbox1"></textarea>

      <label for="bio">Textbox2</label>
      <textarea id="textbox2"></textarea>

      <button type="button" id="bt" value="Exporter" onclick="saveIndex()" for="textbox"> EXPORT </button>

function saveIndex(){
  var myBlob = new Blob([document.getElementById('textbox').value],{type: "text/plain"});

  var url = window.URL.createObjectURL(myBlob);
  var anchor = document.createElement("a");
  anchor.href = url;
  anchor.download = "textfile.txt";

  anchor.click();
  window.URL.revokeObjectURL(url);
  document.removeChild(anchor);
}

I know I need to probably create a new Blob for my second textarea tag, but I’ve tried that and also tried different ways to implement it into my function without any success. I cannot make another function for the second textarea tag, this must all be done within the current saveIndex() function. Any help would be greatly appreciated!

I am a beginner at programming and I am trying to make a clock project.

I am just at the start of it but my code is already not working. At this point of the project what I am trying to do is just to have the timer running when I click on play.

It would be so nice if I could get a bit of help there.

Here is my code :

import React, { useState } from 'react';
import ReactDOM from 'react-dom'


function App(props) {
 
let minutes = 25
let seconds = 0 

function clockmecanics () {

  if (seconds===0) {

   seconds = 60 
   minutes --
   

 }

 seconds -- 

}

function updater () { 

  while (minutes>0){

 setTimeout(clockmecanics(),1000)

}
}


 
   return (
     <div>
     <h1> CLOCK </h1>
     <h1> Breaklength : 5 </h1>
     <button> +  </button>
     <button> -  </button>

     <h1> Sessionlength : 25 </h1>
     <button> +  </button>
     <button> -  </button>
     
     <h1> {minutes}:{seconds} </h1>

     <button onClick={()=> updater ()}>PLAY</button>
     
     

     <h2>  </h2>

     

       </div>
   )
 }


ReactDOM.render(
 <App />,
 document.getElementById('container')
);

Im trying to make a basic clicker game on JS. But theres a problem.

I tried to make a 2x clicker thing which is the game will ask you if you wanna buy 2x clicker when you reached to 100 clicks. 2x clicks will basically give you 2x clicks.

However i think it broked the entire code since click button is not giving any clicks.

Heres the codes:

JS:

let clickCount = 0;
let clickBoost = false;

document.getElementById("clickButton").onclick = function(){
    clickCount +=1;
    document.getElementById("clickCounter").innerHTML = clickCount;

    if (clickCount += 100){
        let boostyorn = prompt("You have more clicks than 100." + "n" + "n" + "Do you wanna buy 2x Clicks?" + "n" + "(Y/N)")
        if (boostyorn == "Y"){
            document.getElementById("clickCounter").innerHTML = clickCount - 100;
            clickBoost = true;
        }
        else{
            alert("You didn't bought 2x Clicks.")
        }
    }

    if (clickBoost == true) {
        document.getElementById("clickButton").onclick = function () {
            clickCount += 2;
            document.getElementById("clickCounter").innerHTML = clickCount;
    }
}

}

Or Google asked for documents to activate minha conta. I sent, but it was wrong. At the time of forwarding or upload button does not work. I don’t know how to contact you to resolve this issue. Does anyone know?

O Google pediu documentos para ativar minha conta. Enviei, mas um estava com erro. Na hora de reenviar o botão upload não funciona. E não sei como fazer contato para resolver isso. Alguém sabe?

So I am trying to enter a post using postman into a mongo db server but my post just returns empty. When I look into my server nothing has been entered and there is no error

table:

const mongoose = require('mongoose');

//Schema describes how our data looks
const PostSchema = mongoose.Schema({
    fullName: {
        type: String,
        required: true,
    },
    date_created: {
        type: Date,
        default: Date.now
    },
    id: {
        type: Number,
        required: true
    }
});

module.exports = mongoose.model('customer', PostSchema);

Route file

const express = require('express');
const router = express.Router();
const customer = require('../models/customer')
router.post('/', async (req,res) => {
const post = new customer({
    fullName: req.body.fullName,
    id: req.body.id
});
try{
    const savedCust = await customer.save();
    res.json(savedCust);
} catch (err) {
    res.json({message: err});
}
});

module.exports = router;

This is what I submit on postman:

{
    "fullName" : "Joy Robinson",
    "id": 2397
}

And this is the response that I get back:

{
    "message": {}
}

userData is a function that receives user data from an API using getUserByChainAccount. getUserByChainAccount requires a username, which in this case is dynamically retrieved from buyer.

I’m interested in avatar , but I keep getting the following error Unhandled Runtime Error

Hell guys. I have a task with my university class. My task is to do a wordpress site with “my own” customizations.

I already finished the task, on the good way i hope. But i’m trying to make something that my other teammates can’t do, the customization tasks. Recentry i saw a website: cryptonoticias . com and then go some random post, now open the dev console, they have a div which is kinda interesting. if you go on this website and seach on dev console the div: “class=”cri_shortcode” you will see something like a affiliate site. I have experience with elementor and wordpress ( 4/10 score skill to be honest )m but i don’t know how is this made. I want to put on my project website something like this but with recipes, my university project is about cooking website. So in this div they are 4 colums and if you let the mouse hover it show a small popup. Does anybody know how is this possible? it’s not look like a plugin is some js scrip maybe?

Thanks for help guys 🙂

I’m learning JS and I’m trying to code a RPS kind of game with a UI, but I’m doing something wrong somewhere and I cannot figure out where.

Whenever I click on one of the options on the UI, the whole thing just freezes. I struggled a bit with the addEventListener logic, but I don’t know if that’s what’s causing it or if it’s something else.

Here’s my HTML and JS.

I am trying to build an interactive GoogleMap in JavaScript via the API for a small town in which some reside in shared buildings. For such locations I would like to show a vertical “pole” on which there is a clickable marker of my choice for each dwelling and the height of the pole varying depending on the number of dwellings.

Or some other useful visualization for such locations.

Would appreciate suggestions and coding tips.
