We are trying to modify env.const.js file from index.html

index.html

<body>
<script> 
window['localConfig'] = {    // <---------------localConfig can be changed from index.html
   id: 'local123',
   appServer: 'https://local-qa.com/'
}
</script> 
</body>

env.const.js

let URLS = {
  development: {
    id: '456',
    appServer: 'https://abc-qa.com/'
  }
}



// getting `localConfig` from index.html

let API_URL = window['localConfig'] ?  { ...URLS['development'], ...window['localConfig']} : URLS['development'];
module.exports = API_URL;

Getting error as :-

window[‘localConfig’] is not defined

I want to call two IDs with one anchor tag, one in the right sidebar and one in iframe (both IDs are same). onclick functions can also try. I have tried with same ids but its not working.

My requirement.

1. when I click link from left sidebar, ID should be called in right sidebar and iframe.

please note: ids are same with iframe.

$(document).ready(function () {
    $('.nav ul li:first').addClass('active');
    $('.tab-content:not(:first)').hide();
    $('.nav ul li a').click(function (event) {
        event.preventDefault();
        var content = $(this).attr('href');
        $(this).parent().addClass('active');
        $(this).parent().siblings().removeClass('active');
        $(content).show();
        $(content).siblings('.tab-content').hide();
    });
});

I’m trying to create this div dynamically using jquery in angular

  let Word='<div style="position: relative;display: inline-block" *ngIf='+this.show+'">'+ word.trim() + '</div>'

Element is being created but i want to hide it on some condition like i was trying to use *ngIf='+this.show by default it should be hidden and when this.show is true then only this div should be visible.

Any solution Thanks.

je suis en train d essayer de faire le jeux du pendu qui se joue à 2, je joueur 1 marque un mot et le joueur 2 doit essayer de trouver le mot. J’ai réussit à faire en sorte d’afficher autant de “” qu’il y a de caractères dans le mot mais je n’arrive pas à faire de sorte d’afficher la lettre dans le bon “” lorsque la lettre est bonne.

Voici mon code,merci d’avance

let motRentre = document.getElementById("motChercher");

const boutoncherchermot = document.getElementById("boutoncherchermot");
const trouvermotboutton = document.getElementById("trouvermotboutton");
const form1 = document.getElementById("chercherMot");
const form2 = document.getElementById("trouverleMot");
trouverMot = document.getElementById("trouverMot").value;
image = document.createElement('img');
let reponsetableau = [];
let motsecret = "";
const barre = document.getElementById("champs")
let lettre = "";


  function afficherbarre(event) {
      motsecret = motRentre.value;

      lettre = motsecret.split("");
      for (let i=0; i< lettre.length; i++)
      {
        reponsetableau[i] = " _ ";

         
        reponsetableau = document.createTextNode(reponsetableau[i])

         barre.appendChild(reponsetableau);
       
      }
  }


  /*
let lettrerentre = trouverMot.value;
lettre = lettrerentre.split("");
for (let i=0; i< lettre.length; i++)
{
  if(texte[i] == lettre){
   reponsetableau=lettre;

}
}*/



          

boutoncherchermot.addEventListener("click", ajouterlemot);
form1.addEventListener("click", boutoncherchermot);
function ajouterlemot(event) {
afficherbarre();
form1.style.display="none";
}

trouvermotboutton.addEventListener("click", trouverlalettre)
function trouverlalettre(event) {
  validate();
  form1.style.display="none";

}

I keep getting an error saying .forEach is not a function I have a very similar function that runs just fine but I can’t figure out how to fix this forEach issue

function populateRepsDiv(repsArray) {
  removeChildren(senatorDiv)
  repsArray.forEach(representative => {
    const repFigure = document.createElement('figure')
    const repImg = document.createElement('img')
    const repCaption = document.createElement('figcaption')

    repImg.src = representative.imgURL
    repCaption.textContent = representative.name

    repFigure.appendChild(repImg)
    repFigure.appendChild(figCaption)
    senatorDiv.appendChild(repFigure)

    console.log(representative.name)
  })
}

I have an iframe that shows a page with a list of objects.

I have another page where the user can create new objects.
I would like to update the iframe content showing the list updated with the new object created.

controller.html

      allowfullscreen sandbox="allow-scripts">
      </iframe>

<button onclick="obj.create()">Create </button>
</html>

controller.js

//function that is called after the user has created a new object

 getObjList(){
  let iframe  =  document.getElementById('iFrame');
  var iframeDocument = iframe.contentDocument || iframe.contentWindow.document;
  var obj_list
  var obj_message

if (iframeDocument) {
  obj_list = iframeDocument.getElementById('obj_list');
  obj_message = iframeDocument.getElementById('obj_message');
}
$.ajax({
    type: "GET",
    url: '/objects/iframe',
    success: function success(answer) {
      if (obj_list.innerHTML !== ""){
     
        $('#obj_list').html("")
      }
    
      if (typeof answer === 'object') {
        if (answer.message === 'ok'){
        if (answer.result.length > 0){
       
          obj_message.css('display', 'none');
          obj_list.css('display', 'block');

            for (let i=0; i<answer.result.length; i++){
                 obj_list.append(`

iframe.html

<html>
        <h2>LIST OF Obj - IFRAME </h2>
        
            <!---OBJ CONTAINER LIST-->
            <div id="obj_list">

                <p>There have not been created any objects</p>
            </div>
    </div>
</html>

The problem I am having is that I am not able to update the content inside the iframe.
I get this error:
Blocked a frame with origin “xxxxxx” from accessing a cross-origin frame

Is there a way I can achieve the update of the content of an iframe?

The content of the iframe is a page I manage, that later has to be embedded in another website.

I have my table that displays all the id and title of my menu (1) (see menus.json). I want to add an hyperlink to my title but it doesn’t work:

{
    Header: "Title",
    // accessor: "title"
    accessor: (row) => row.title,
    // Link the content of my cell. NOT WORKING 
    Cell: ({ row }) => (
      <Link to={{ pathname: `/menu/${row.id}` }}>{row.title}</Link>
    )
}

By clicking on my title name,ex Menu1 (1), it will redirect me to a new page with a table that contains all the names of the menus that match my id_menu (2) .

Here a picture to get what I’m saying :
(1)

(2) When you click on Menu1 you should get (not working):

(same idea for the other menus)

Thanks for your time.

Have a simple search bar (input field) which should trigger an onSubmit action while we press Enter button

I’m super new to JS and am struggling with a very basic task as I familiarize myself with it. I want to create a simple run(cmd) function that would receive a string with a command, and return an object containing stderr and stdout.

From what I found, I need to use exec or spawn, but I’m having trouble turning the examples online into a returning function:

const { exec } = require("child_process");

let run(cmd) = exec(cmd, (error, stdout, stderr) => {
    ret = {
        out: "",
        err: "",
        msg: ""
    }
    if (error) {
        ret.msg = error.message;
    }
    if (stderr) {
        ret.err = stderr;
    }
    ret.out = stdout;
    return ret;
});


out = run("ls -al");
console.log(out);

This doesn’t work and I’m probably making mistakes on multiple levels here

I’ve this function with map, how can call only when finish?

 _.map(data,async function (el) {
        if(Number.parseInt(el) != NaN && (el != null) && !isNaN(el)){
            console.log('ID: ' + el)
            await scrapeDetails(el) // <--- need to wait finish and than go to next element in map
        }
    })

async function scrapeDetails(id){
// ... bla bla
}

I’m in the process of learning React, and I found out that trying to pass “key” or even “ref” props to components does not work.

From a bit of research online I found that you can just pass a duplicate prop with the same data in it and it will work. But I couldn’t find why it isn’t allowed in the first place aside from answers stating that React uses these props internally.

I am trying to do the discounted price logic

Discount price should have the default value of actual price , because 0% discount means the discount price is same as actual price.

when i do this i am getting this error, And it is changing randomly sometimes, and most of the time it is working fine .

import React, { Fragment, useState } from "react";
 
const App = () => {
  const [price, setPrice] = useState(0);
  const [discountPrice, setDiscountPrice] = useState(0);
  const [discountRate, setDiscountRate] = useState(0);

  const submitHandler = async () => {
    console.log("hello");
  };

  return (

          </div>
        </div>
      </Fragment>
    </>
  );
};

export default App;

And how to actually see if the discount price value is empty ?

i tried

discountPrice == "" || discountPrice.trim() = "" || discountPrice== null
discountPrice.trim()===""

is not working, says trim is not a function

I have a premade react app page with all the components already built but at the end of the page, I need a button so that when you click on it you either get all the fields of the page or just a screenshot of the actual page. How can I do this?

I try to send SMS(Text message) to a specific mobile number(MA : Morocco, FROM : Morocco) using AWS SNS service using nodeJs I get a success and the data looks like:

{“MessageID”:”ea4cf..”}

However, the SMS does not get delivered.

Here is the code:

router.post('/send-text', (req, res) => {

   var dynamoDBConfiguration = { 
    apiVersion: '2010-03-31',
     accessKeyId: 'A...',
     secretAccessKey: '...',
     region: 'eu-west-3'
    };


AWS.config.update(dynamoDBConfiguration);

// Create publish parameters
var params = {
  Message: req.body.message,
  PhoneNumber: '+' + req.body.number,

  MessageAttributes: {
    
      'AWS.SNS.SMS.SenderID': {
          'DataType': 'String',
          'StringValue': req.body.subject,
          
      }
  }
};
// Create promise and SNS service object
  var publishTextPromise = new AWS.SNS({ apiVersion: '2010-03-31' }).publish(params).promise();

  publishTextPromise.then(
    function (data) {
      res.end(JSON.stringify({ MessageID: data.MessageId }));
    }).catch(
      function (err) {
        res.end(JSON.stringify({ Error: err }));
      });
