Making a regexp to retrieve href/src of html tags

Im trying to get the href from links and src from script tags.
Since it’s my first time using regex, im isuing quite not enough understand on how groups, negation and conditional selection works.

This is what i’ve got so far

(/|./)((^([http|https]://))*.*?w+)([a-zA-Z]w+)(?=.(js|css|ts)b)(.*?w+)

Working in this cases:

<script src="./script.js"/>
<script src="/script.js"/>
<script src="/my/custom/dir/script.js"/>
<!--Theme same for links-->

Non functioning cases:

<script src="https://my.cdn.fav/script.js"/>
<script src="http://my.cdn.fav/script.js"/>

Or well it does consider the starting http and https but doesnt select them.
It’s this part that is doing something wrong (/|./)((^([http|https]://))

Issue with Fetch Request in a TypeScript react app

I am developing a react app and encountering an issue with a fetch request in my TypeScript file. The app is supposed to send a POST request to a Flask server running on localhost:5000. However, when I include the fetch request within a try-catch block inside a method of a class, the extension’s webpage fails to render any elements, and there are no errors logged in the console.

Here is the relevant code snippet, showing the location of the method within the class:



import fetch from 'node-fetch';

class InfoProvider implements Disposable {
  // Other class properties and methods...

  private async sendProofState(proofState: string) {
    try {
      const response = await fetch('http://localhost:5000/api/generate_tactics', {
        method: 'POST',
        headers: {
          'Content-Type': 'application/json'
        },
        body: JSON.stringify({ proof_state: proofState })
      });
      const data = await response.json();
      console.log("Response from Flask server:", data);
    } catch (error) {
      console.error("Error sending data to Flask server:", error);
    }
  }
//other methods
}

The issue seems to be specifically related to the fetch request, as commenting out this block allows the webpage to render correctly. I have confirmed that CORS is enabled on the server, and the server is running without issues.I even commented the line where the function is called and the issue persisted.

HTML button not clickable despite adding onclick listener

I’ve created a “+” button to send text from an input field to my Firebase database. However, the result is not showing up in that database, and the “+” button is not clickable 🙁 Please take a look at my code below.

index.html:

<!doctype html>
<html>
    <head>
        <title>Reel Time</title>

        <script src="functions.js" type="module"></script>
        <script src="index.js" type="module"></script>
    </body>
</html>

index.js:

import { initializeApp } from "https://www.gstatic.com/firebasejs/9.15.0/firebase-app.js"
import { getDatabase, ref, push } from "https://www.gstatic.com/firebasejs/9.15.0/firebase-database.js"

const appSettings = {
    databaseURL: "https://playground-91206-default-rtdb.asia-southeast1.firebasedatabase.app/"
}

const app = initializeApp(appSettings)
const database = getDatabase(app)
const moviesInDB = ref(database, "movies")

const inputFieldEl = document.getElementById("input-field")
const addButtonEl = document.getElementById("add-button")

addButtonEl.addEventListener("click", function() {
    let inputValue = inputFieldEl.value
    
    push(moviesInDB, inputValue)
    
    console.log(`${inputValue} added to database`)
})

functions.js:

export function add(a,b) {
   return a + b
}

Please advise 🙂

Why RecatJS do not update value when it changes

I`m learning React and I do not understand – why in first render React generate correctly value playerSymbol, but when It changes it is not re-render even when gameBoard changes. Code:

import { useState } from "react";

const initialGameBoard = [
 [null, null, null],
 [null, null, null],
 [null, null, null],
];

export default function GameBoard() {
  const [gameBoard, setGameBoard] = useState(initialGameBoard);

  function handleSelectedSqare(rowIndex, colIndex) {
    console.log("aaaa");
    setGameBoard((prevGameBoard) => {
      const updatedBoard = [
        ...prevGameBoard.map((innerArray) => [...innerArray]),
      ];
      console.log(updatedBoard);
      updatedBoard[rowIndex][colIndex] = "X";
      return updatedBoard;
    });
  }

  return (
    <ol id="game-board">
      {initialGameBoard.map((row, rowIndex) => (
        <li key={rowIndex}>
          <ol>
            {row.map((playerSymbol, colIndex) => (
              <li key={colIndex}>
                <button onClick={() => handleSelectedSqare(rowIndex, colIndex)}>
                  {playerSymbol}
                </button>
              </li>
            ))}
          </ol>
        </li>
      ))}
    </ol>
  );
}

Any idea guys?

nextjs 13, 14 App Directory language without i18n – internalization

Question: Is there a way to do multi-language without i18n since it’s a 2 pages website…

The context

The root layout has the language detection:

1- Using a context that record french if french or else is english.

<script async dangerouslySetInnerHTML={{ __html:(function () {
function setTheme(newTheme) {
window.__theme = newTheme;
window.__onThemeChange(newTheme);
}
// this will be overwritten in our React component
window.__onThemeChange = function () {};

              // this will be triggered by our React component
              window.__setPreferredTheme = function (newTheme) {
                setTheme(newTheme);
                try {
                  localStorage.setItem("lang", JSON.stringify(window.__theme));
                } catch (err) {}
              };

              // detect system theme and monitor for changes
              var darkQuery = navigator.languages ? navigator.languages[0] : (navigator.language || navigator.userLanguage)
              darkQuery = darkQuery.split('-')[0];

              var preferredTheme;
              // try to get saved theme
              try {
                preferredTheme = JSON.parse(localStorage.getItem("lang"));
              } catch (err) {}  
              // initialize preferredTheme
              setTheme(preferredTheme || darkQuery);
            })();`
          }}
        />

`

The goal is to use the contect “en” or “fr” to render the correct json caracter. At the moment I am stuck at the json part.

How to know the action sent to server by a button on a webpage? do you use a chrome addon for that?

how do you process to know the action sent to the server by this ‘Delete’ button on a webpage? do you use a special Chrome addon?


<div _ngcontent-geev-pwa-ssr-c1357586839="" class="modal-footer glob-font-body-bold">
  <button _ngcontent-geev-pwa-ssr-c1357586839="" type="button" class="modal-footer-cancel">Dismiss</button>
 ** <button _ngcontent-geev-pwa-ssr-c1357586839="" type="button" class="modal-footer-validate"> Delete </button>**
</div>

Screenshot

I have used Chrome built-in inspect tool, but this does not provide me any info about the action being actually requested to the web server, what else can I do to find it?
